How to poison food moths. Grain or food moth: how to get rid of larvae and adults and eliminate the source of infection. What modern means are safe?

The first thought that comes to the housewife when she discovers moths in the kitchen is the lack of order in the house. It is too common for people to think that any insects in the home are caused, first of all, by dirt, and only then are other causes considered. In fact, for food moths it makes no difference where to live, in a barracks or in a villa, the main thing is that there is enough food. In this article we will look at the question of how to get rid of food moths in the kitchen.

Oddly enough, the most common way for food moths to enter a home is by bringing it with food purchased in a store.

Leaky packaging of cereals, nuts, flour, dried fruits, etc., plus improper storage of products in warehouses or directly in the store - this is an excellent opportunity for moths to get inside the package, and then into the apartment. In fact, man with my own hands brings a problem into your home.

There is also a possibility that moths will come from neighbors with whom they already “live”, but this happens less frequently: moths fly well, but not over long distances. An insect can get from one apartment to another through ventilation holes or in a simple way- through open window or a door.

If on the ground floor of a residential apartment building there is grocery store, it can also become a source of moths getting into people’s homes.

Causes of infection

As has already become clear, absolutely no one is safe from food moths getting into their homes. Just one fertilized individual flying into an apartment is enough for a whole colony of pests to develop here after a while. And it won’t take much time to reproduce them if certain conditions are met:

  • access to food and water (food is spoiled by larvae, but adults do not feed at all, they simply do not have a mouth);
  • rarely ventilated room (moths cannot tolerate fresh air);
  • tight and long closed cabinets, boxes with food (there, in the dark, in the secluded corners of the moth, it is very comfortable, since she does not like light either);
  • absence of repellent aromas;
  • open packages of dry products, where it multiplies and dies.

The pest will like such a comfortable home and will be happy to start and live in it.

Some types of moths eat the keratin found in the horns of African antelopes.

Damage caused

A flying adult does not pose much harm to humans; it does not bite or eat food. But it is capable of laying eggs in food products to which there is open access, and if this is not noticed in a timely manner, larvae will quickly appear there.

Food moth larvae contaminate the food in which they live with their excrement. Also everywhere you can find the corpses of these insects and the chitinous shell that is shed during rebirth.

Of course, this should not be allowed and food moths must be fought.

Struggle

Withdraw food moth– it’s not an easy matter. It is necessary to fight the entire colony at once, for which there are both popular and chemical methods. However, not all of them are good enough, since moths easily adapt and get used to even aggressive chemicals. Therefore, it makes sense to either change the remedy, or use several (at least 2) methods of struggle in parallel at once. But the first thing to do before starting the fight is to throw away all damaged products.

To save money, many try to save cereals and nuts by roasting them in the oven. Yes, in this way it is possible to carry out thermal disinfection of products, and thereby destroy the eggs or moth larvae that were there before processing. But not everyone will then be able to purely psychologically eat foods on which moth larvae had recently crawled.

Traditional methods

While there are not many moths, you can try to lime them at home using several traditional methods:

  • Vinegar. It has been used against food moths since ancient times. First, the cabinets are emptied and washed with soapy water. After this, you need to arrange a draft in the kitchen for half an hour. Then everything is treated with vinegar internal corners, walls and shelves of cabinets, drawers, etc. kitchen furniture, and the windows close for an hour. After this time, the room must be ventilated.
  • After getting rid of contaminated products, dead wood (or fresh plants) of lavender, mint, and wormwood are placed in the cabinets. Close the doors tightly. You can also apply them essential oils.
  • Garlic. Open cloves are placed on shelves inside the kitchen furniture, but this method should not be abused: the moth, having gotten used to the smell of garlic, begins to eat it too.
  • To prevent moths from entering the house through a window, it is useful to grow geraniums on the windowsills, the smell of which the pest does not like so much.

If cereals (or flour products, nuts, etc.) were in the cupboard in open form, and moth larvae have managed to breed there, the placement of repellent plants (for example, lavender) inside such a cabinet can play a cruel joke. The fact is that the larvae from the package with the product will still not be able to escape until they have turned into adult flying individuals. Therefore, they have no choice but to inevitably get used to the unpleasant, but not fatal, smell that envelops them. As a result, you can raise a generation of moths with your own hands, which in this case are no longer afraid of lavender, etc.

Application of chemistry

To beat the enemy for sure, together with folk remedies can be used chemicals:

  • Insecticides. Among aerosols, you can look for those specifically designed to combat moths. But you shouldn’t use them many times in a row: the moth quickly adapts to them and stops reacting. However, these products can give excellent results if everything is done correctly right away (by following the steps preceding spraying and following the instructions for using aerosols).
  • Purchased traps (Raptor, Argus, Delta-250, etc.) work to attract adults with their scent. Having flown into the trap, the insect sticks to a special Velcro and dies. The whole benefit of a trap is that an individual caught there will no longer produce offspring. This poses no threat to the larvae.

Prevention

To prevent kitchen moths from appearing at home, you just need to fulfill certain conditions that will destroy the slightest desire of the pest to settle in the apartment or eliminate this possibility altogether:

  • inspecting purchases while still in the store for the integrity of the packaging and the presence of larvae;
  • periodic “audit” of products at home;
  • store bulk and dry products in plastic or glass tightly closed jars;
  • at least occasionally place repellent herbs in the kitchen furniture (or use essential oils with these aromas);
  • to prevent moths from entering through the ventilation, cover its grille with a dense mesh with small cells;
  • frequently ventilate the room;
  • wipe shelves and drawers with vinegar solution from time to time;
  • do not stock up on food for a long time;
  • place dry orange peels on the shelves (moths, any moth, are afraid of them).

Thus, control over products and careful attention to your choice in the store are, perhaps, the main conditions, the fulfillment of which will save your apartment from the invasion of food moths.

Food moths frighten many housewives. At least once in her life, every lady has encountered unpleasant insects, perplexedly trying to understand where the flying moths came from in the kitchen. Initially, it is necessary to find the source of insect reproduction, then suppress the destruction of uninvited “guests”.

The process of getting rid of food moths is unpleasant, lengthy and expensive. Be sure to study the rules for preventing the appearance of insects in your home, because preventing food contamination is much easier than trying to get rid of larvae and adult insects later.

What is food moth

The insect is a pest with a short breeding cycle. Food or grain moths belong to the butterfly family. Adults are beige in color, sometimes light brown. There are also larvae that look like caterpillars; the eggs are light-colored. The larvae vary in size depending on the type of insect, sometimes reaching a length of two centimeters. It is this form of the pest that is considered the most harmful to humans. The larvae devour food and envelop nuts, fruits and cereals in an unpleasant web.

Maximum lifespan adult(butterfly) does not exceed a few days, then the insect lays eggs and dies. During the breeding season, the pest turns into a wingless butterfly, when it destroys many food supplies. This period can last up to six days. Reproduction process grain moth accelerates if environment warm and humid. Therefore, the absence of flying moths is not a reason for peace. At this moment, the larvae can safely feast on your supplies.

Note! The most important thing in the fight against insects in the kitchen is to periodically check all containers with dry products, and not just get rid of the pest once.

These questions worry many housewives, because many believe that they themselves are to blame for the contamination of food with insects. You can’t assume that, you can only take care of your kitchen, but it’s impossible to watch other people. Often, goods purchased in a store (especially on sale) are already contaminated with moth larvae. Unscrupulous owners of wholesale warehouses neglect the rules for storing products. Insects also make their way into the home through ventilation, through windows.

Favorite places for food moths:

  • cereals Favorite place habitats of grain moths: rice, oatmeal, rolled oats, pasta, even portioned bags of cereals are not immune from pest infestation;
  • nuts. The moth lives in shelled peanuts, under the shells of walnuts;
  • dried fruits. Raisins, prunes, dried apricots are often covered with some kind of mold due to moth enveloping the product;
  • carton boxes. Sometimes the larvae are found in unpacked packets of tea, cornflakes, or oatmeal;
  • if insects have been living in your kitchen for a long time, then perhaps they live under window sills, behind cabinets; there are rare cases of grain moths living even in household appliances, which has not been used for a long time;
  • There is an opinion that insects are afraid of garlic, but some claim that they have found larvae even in bags of vegetables;
  • There are foods that moths do not eat, but live in them well (salt, soda). When inspecting the kitchen, pay attention to these bulk items.

Caustic (vinegar) and viscous (honey, wait, jam) are not susceptible to infection, because insects simply drown in them.

You shouldn’t panic when you discover a pest; gather yourselves and immediately begin destroying grain moths.

Harm and danger

Many people believe that the insect is absolutely harmless to humans; it’s okay if it eats a couple of grains. It is strictly forbidden to think so. The main problem with grain moths is that an adult can lay about 500 eggs. Each larva changes its skin several times during its short life and contaminates food with its vital activity. Cereals and nuts contain a lot of feces and chitinous covering (insect skin).

Regular consumption of contaminated foods, sometimes even one meal, can lead to dire consequences:

  • food poisoning, serious intoxication of the whole body;
  • severe allergic reaction, including angioedema, which sometimes leads to death;
  • malfunctions of the immune system.

All doctors and exterminators insist that after discovering insects in the kitchen, you need to get rid of them very quickly. Food moths pose a particular danger to children. A fragile body may react acutely to a meal of contaminated foods.

General rules for insect control

  • it is a mistake to put cereals in the refrigerator, low temperatures only lead to the larvae falling asleep. After returning to a humid and warm environment, insects will begin to actively reproduce
  • larvae and eggs die only when high temperatures. It is allowed to steam the cereals in the oven for at least 20 minutes, otherwise some individuals may survive and the disinfestation will have to be repeated again;
  • it was not for nothing that our mothers and grandmothers stored cereals and dried herbs in tin cans. Insects are unable to chew through metal, glass, wood and foil. But fabric, paper, plastic lids - easily. Store all edibles in tightly closed glass containers with special seals. This way you can see the pest through glass jar, insects will not crawl throughout the kitchen;
  • Wash all jars containing contaminated cereals in a vinegar solution. Regular soap has no effect on moths; insects can even live in packets of powder. It is allowed to wash with a soap solution after vinegar treatment for additional hygiene.

Important! No method will help unless you destroy all contaminated food. It is also recommended to thoroughly wash the furniture, the room itself, and general cleaning, adding a little table vinegar to the water for washing floors.

Completely rid the kitchen of annoying insects Chemical agents will help, which eliminates the possibility of saving contaminated products. All remedies against grain moths can be divided into two groups:

  • eradication insecticides. Products consist of chemical elements aimed at poisoning adults, larvae, and killing eggs;
  • repellents. The products include only natural ingredients that can repel insects. The products cannot destroy moths, but contribute to their migration to other territories.

Aerosols

How to deal with food moths in an apartment? One of the most effective means aerosols are considered. Manufacturers produce a lot of products, similar in composition and action, designed to rid the kitchen of food-eating insects in a short period of time.

Popular aerosols:

  • Antimol. Allowed to be used on kitchen furniture, fabrics, the duration of action of the product is amazing - the effect lasts up to one year;
  • Armol. The product is designed to quickly kill moths; the product affects not only butterflies, but also has a prolonged effect against larvae;
  • Battalion commander Famous universal action, destroys all types of moths. The product is safe for pets and can be used on all surfaces.

For help with choosing the right aerosol, contact a consultant at a specialized store. Consider the presence of children in the house. During disinfestation, it is better to leave the premises, take pets, children, even plants. Then ventilate your home thoroughly; insects cannot stand fresh air.

Traps

Flying individuals must also be destroyed to prevent the resumption of contamination of food. To do this, some use regular newspaper or slippers. The moth flies poorly, catching it is not difficult. If you don't like this method, use commercial traps that attract insects. The products are lubricated with a special substance, the pest sticks and can no longer fly, eventually dying.

The Aeroxon food moth trap has proven excellent. The adhesive surface of the product does not dry out for a long time, and the special aroma attracts butterflies. The trap can be purchased at any hardware store; the cost of one package does not exceed 200 rubles. One trap should be enough to completely destroy adult individuals; if this does not happen, purchase another product.

Prevention of occurrence

You can reduce the damage caused by moths and prevent their occurrence in the house using the following recommendations:

Grain moths are a nuisance, but you can get rid of them. Stick to it useful rules, if necessary, engage in pest control.

Food moths start very easily, but are very difficult to remove. If you notice centimeter larvae in your kitchen white or fluttering insects - take immediate action. Which? Watch this helpful video:

Food moth repellents are used to keep food safe. Small butterflies seem harmless, but in practice it turns out that they are quite dangerous insects. If you do not get rid of food moths in time, they will undermine existing supplies. Eventually they will have to be thrown away. You can save products that are less affected.

If there is a moth, it is probably a representative of one of the species:

Such insects are more often found in private housing within the kitchen. Wingspan – up to 8 mm. The color is pale: from beige to brown. The upper wings are darker than the lower ones.

The pest reaches 1 cm in length. When the wings are folded, representatives different types insects are similar to each other, since the color is difficult to see.

The larvae reach 1.5 cm in length and are characterized by a light color. If adults differ in external signs, then young offspring are sometimes difficult to distinguish.

Damage caused

It is imperative to remove moths from the kitchen, as otherwise they will destroy most products. Insects feed on cereals and flour, nuts, dried fruits, as well as seasonings, tea, chocolate products and seeds. They spread through the air (fly into windows, through ventilation), and enter the apartment with products brought from the store. Accordingly, it is impossible to completely protect yourself.

Eating food contaminated by insects can lead to a severe allergic reaction.

It is recommended to begin fighting insects immediately after signs of infestation appear: rot at the bottom of containers with bulk products; change in the structure of flour and cereals (they become lumpy). The nuts have holes made by caterpillars. The appearance of the product deteriorates, cocoons and cobwebs are noticeable, and larvae are detected. It's especially unpleasant when they end up inside chocolates, because in this case the caterpillars are difficult to notice.

A butterfly can appear suddenly, even if the house is kept clean and not stored a large number of stocks. You can get rid of food moths in your apartment different ways, but first you need to find the source of infection. To completely exterminate all individuals and offspring, it is necessary to clean the kitchen.

To destroy larvae and eggs, certain means are used, since not all drugs have an effect on the young offspring of butterflies. In addition, you need to decide what to do with moth-infested products.

Finding the source of infection

Before getting rid of the moth itself, you should find the source of its appearance. Butterflies leave offspring in different places, where in a week the larvae will appear and begin to destroy the product. Cobwebs and large black-headed caterpillars are noticeable in their habitats. Moth eggs are difficult to spot because they small size(no more than a grain of semolina) and white.

First you need to inspect the ceiling and cabinets for the presence of butterfly cocoons. They are usually on ceiling skirting boards, wallpaper joints, at the base of lamps, in cracks and corners. Pest cocoons are also found in the upper parts of cabinets.

The first step is to inspect the products. You should look for stuck together grains and larvae.

Cleaning the premises

Pest control involves cleaning the entire kitchen. It is necessary to get rid of traces of insects. Heavily contaminated food is thrown away first. Having gotten rid of the source of pests, they move on to cleaning the furniture from the inside. To do this, the contents are pulled out, and shelves are also taken out of cabinets if possible.

Using a vacuum cleaner, you need to go through all the corners, crevices and surfaces with the nozzle. The air flow will attract insects. It is better to throw away the dust bag, but you can also leave it in freezer for a few days. This will kill the insects.

The surfaces inside the cabinets should be treated with a vinegar solution or insecticides (Antimol, etc.). Storage containers bulk products It is also necessary to wash it with a vinegar solution or laundry soap.

Chemicals and traditional methods

An aerosol is suitable for treating cabinets and other surfaces, but only if food is not stored inside. This food moth repellent is not used for spraying food. Popular options: Raptor, Raid, Armol, Combat Super spray.

Of the named drugs, only Armol destroys only adult individuals. If the task is to breed young ones (larvae and caterpillars), then you should use Raptor, Combat, Raid.

Special sections allow you to get rid of butterflies: Globol, Raptor, Moskitol. They are located in the corners of the room, close to the source of infection. This product should not be stored near food.

If moths are found in cereals, then you should consider glue traps. They use a pheromone to attract males. Without males, butterflies will not reproduce.

You can also fight the pest with folk remedies:

  • Dried lavender or essential oil
  • Laundry soap. It is cut into pieces and laid out around the room
  • Lemon, orange zest
  • Strong-smelling herbs: tansy, wormwood, cloves, rosemary, thyme or mint.

Home methods repel pests, but do not lead to death. For this reason, they are considered only as an auxiliary measure to combat moths.

How to handle contaminated products?

Destructive temperature for the butterfly and offspring: more than -10 and above +30 degrees. To be safe, the products are processed in the oven at +60 degrees or higher, or by placing them outside if it is hot outside.

An effective way to control pests is freezing.

The name “food moth” is popularly understood to mean several types of moths - small butterflies whose caterpillars feed on cereals, nuts and groceries. Each of these species has its own characteristics, however, despite the fact that outwardly different types of food moths differ well from each other, no one particularly wants to understand them and is simply looking for ways to get rid of these pests as quickly as possible.

At the same time light and universal instructions, how, no - due to the specific feeding habits of these butterflies, conventional methods such as aerosol insecticides are not suitable (after all, the poison can get into food). Therefore, the fight against food moths is always quite a troublesome and resource-intensive undertaking.

This is interesting

Before the development of human civilization, all types of moths were fairly inconspicuous participants in natural biocenoses, and their caterpillars fed on the seeds of grasses and trees. But with the advent of granaries, barns and warehouses, and especially with the beginning of active transportation of goods between countries and continents, food moths quickly spread throughout the world and became a real cosmopolitan, equally effectively infecting grain in Argentina, China and Chad. And even today industrial methods Fighting food moths does not always cope with its destructive activities.

Types of food moths and features of their morphology

If you look at photos of different types of food moths, you may be surprised how they are generally confused and combined under one name. For example, in the photo below there is a flour moth, one of the most common types of food moths in an apartment:

But the southern barn moth, which has beautiful drawing on the wings. Getting it out is often the hardest thing to do:

And in the photo below you can see what the cocoa moth looks like - a common food moth, which can easily be confused with a clothes moth due to the inconspicuous light yellow color of the wings:

But in general, any food moth looks inconspicuous, even despite the pattern on the wings of some of its species. All of them are butterflies of discreet colors and small sizes.

Usually the length of their wings does not exceed 7-8 mm, and when sitting on the surface, the insect folds them and becomes like a small protrusion on the surface. It is not surprising that the simple glance of a city apartment resident is usually not able to discern the difference in the color of these butterflies.

On a note

For an unprepared resident of a big city, food moths and clothing moths are very similar. The easiest way to distinguish them is by their meeting places - clothing moths rarely catch your eye in the kitchen, while food moths, on the contrary, do not favor wardrobes and bedrooms with their attention.

But the larvae of food moths all look the same. These are small (up to one and a half centimeters) white-yellow or white-pink caterpillars without any hair or outgrowths on the body. Usually by appearance It is impossible to determine whether a caterpillar belongs to one or another moth. Fortunately, they can all be hatched using the same methods, and it is not necessary to determine the species of the larvae for this.

For example, in the photo below is a larva of the meal moth:

And in the next picture is a cocoa moth larva. Even despite the obvious differences in the color of adult butterflies, their larvae are very similar:

On a note

Food moth larvae lead a secretive and sedentary lifestyle. They are usually encountered either in contaminated products or when crawling out of cabinets to pupate. In this case, they move along the walls and greatly attract attention. The photo shows an adult food moth larva ready to pupate.

Food moth: a little biology

Food moth is a pest with a fairly short reproduction cycle. At suitable temperature and humidity, it takes about two months, and sometimes six weeks, from egg to egg.

The optimal conditions for the development of food moth butterflies are a temperature of about 25°C and a humidity of about 50%. At these air parameters, they develop most quickly, and it turns out to be very difficult to remove them.

Adult food moth butterflies do not feed at all: their oral apparatus is not developed and the digestive system does not function. And they don’t live very long - about a week, mating literally on the first or second day after emerging from the pupa. The females devote the remaining few days to laying a hundred to one and a half eggs where future offspring will find enough food, and the males look for other females or die.

In general, taking into account the larval stage, the food moth lives for about a month and a half. Of these, a week or two is spent on metamorphosis in the pupal stage.

Almost always, food moths reproduce in the same place where their larvae live. Only in some cases do adult insects mate away from the grocery store, and the females then return to the feeding environment.

Pest in an apartment: how does it get here, where does it live and what does it eat?

Food moth larvae feed on groceries. Moreover, food moths eat almost everything indiscriminately: cereals, flour, sugar, cocoa, nuts, dried fruits, bread, crackers, cookies, not very hot spices, unground grains, etc.

Food moth larvae are especially numerous in grain warehouses, which can cause significant damage. Each species has its own food preferences, but in general the range of food products for each moth is wide. In an apartment, any type of food moth feeds on almost any grocery product.

Thus, wherever there is dry food, food moths can appear.

The photo shows dry apricots, among which the larvae of food moths are visible. In case of mass infestation of large volumes, it can be extremely difficult to remove moths from such a product:

Each food moth larva not only eats the product in which it lives, but also constantly weaves itself into a cocoon of silk. This is how “incomprehensible” lumps and pellets appear in cereals or flour, and neat nests with a worm inside appear in nuts.

It is important to understand that food moths are very poor fliers. Spread between houses, and even more so between food warehouses And she can’t live in apartments herself, and in the apartment food moths are taken only with purchases and products from the supermarket. Food moths also breed in industrial warehouses: their larvae are transported in grain from one warehouse to another, and their descendants already master the abundant food sources.

Harm from food moths

The main harm of food moths is food spoilage. Moth-infested groceries are no longer edible, and in industrial warehouses, contaminated food is unsuitable for sale.

If there is a serious infestation in a warehouse, food moths are dangerous big losses product and a strong decrease in its quality.

On a note

It is moth-infested and secondary purified products that enter the market at bargain prices - after all, they need to be sold somehow. And by buying them, an ordinary city resident risks bringing a pest into his home with them.

Food moths do not eat clothes and are not dangerous to the wardrobe. This, however, does not mean that if there are food moths in the room, you should not worry about things: clothes moths and food moths do not interfere with each other and can easily coexist in the same apartment, while mainly food moths will be seen. In any case, you need to remove the moth from the first signs of its detection in the house.

Fighting food moths: measures and means

It is necessary at all stages of its development. It is incorrect to say that if only the larvae are harmful, then only them need to be destroyed: each flying female moth lays up to 160 eggs in different places, from which new caterpillars will hatch within a week.

Therefore, it is necessary to destroy food moths in a comprehensive manner:

A good tool for catching butterflies is the Aeroxon food moth trap. It attracts butterflies with its smell, and its adhesive surface does not dry out for a long time. You can buy such a food moth trap online or at some hardware stores. Its cost is about 200 rubles:

More simple methods control of food moths has not yet been developed. On industrial enterprises against moths, phosphine-based fumigators and grain spraying with contact insecticides are used. Conduct similar treatment food products indoors is not allowed.

Measures to protect your home from food moth infestation

Knowing how to kill food moths is useful, but not enough to protect the premises from the pest. It is much wiser not to let him into the house at all, taking several steps to prevent infestation of the apartment with food moths. Among these measures:

  • thorough check of all products upon purchase
  • avoidance of grocery products with obviously low prices
  • purchasing food that will be eaten within one week
  • use of moth repellents.

To comply with the last point, it is useful to know. Among the substances that repel it are strong-smelling herbs (wormwood, tansy, lavender, rosemary), essential oils, fresh orange peels, laundry and strawberry soap, vinegar, horse chestnut cones.
