Highly a good remedy with a problem, how to get rid of cereal bugs in the kitchen is to process all the shelves where the products are placed with an vinegar solution, in the proportion of one tablespoon per liter of water. You can place bags with pyrethrum (a kind of chamomile) in the corners, the smell of which, like vinegar, can scare away not only bugs, but also moths. Experts recommend treating cracks with boiling water, however, not all coatings are temperature resistant.
Any insects large or small bugs in the kitchen, not a single source will tell how to get rid of at least part of the cereals.

There is a possibility that the poison will be eaten and as many individuals as possible will be brought to the nest, and this will lead to the death of most of the colony.
How the bait is made:
In emergency situations, when there is nothing to cook from, you can use water. The affected croup is filled with water (it can be salty), under the influence of the pressure of the croup, it sinks down, and the insects float up. The cereal itself must then be thoroughly rinsed from contamination. The remaining bugs in the cereal, how to get rid of them, you need in several stages, after washing and calcining, it is advisable to sift everything again. In order to avoid shock at the sight of live insects, before filling the cereal with water, it must first be ignited.
This method is not suitable in the case when the bugs are in flour, we have already told how to get rid of them.
Previously, people did not have the opportunity to ignite under high temperature or freeze food. More recently, spoilage of such a product as cereals was considered a great misfortune, but even then the spoiled product was given to animal feed. In order to prevent the bugs from appearing at all, other methods were used.
How to get rid of bugs in the kitchen with folk remedies:
Summing up, I would like to say that there are no magic methods for getting rid of bugs in croup forever. All the same, you cannot be 100% sure of the products of the same store or warehouse where these products are packaged. The main guarantee is the careful observance of cleanliness in the kitchen and the constant treatment of surfaces with disinfectants.
My friend has been struggling with a sticky problem for a long time. In her locker with cereals, bugs constantly settle. In search of an answer to the question of how to get rid of bugs in croup, we decided to try all known methods. As the saying goes, in war all means are good.

How the bait is made:
People who value their time and nerves prefer to turn to experienced exterminators from the sanitary service. Specialists have years of experience, as well as knowledge about the behavior of insects.
It is important to note that the insecticides that masters use have a detrimental effect on pests, but at the same time are harmless to humans, pets and animals. environment.
They belong to the 4th class and do not spoil the decoration of the apartment. In addition, the products do not have an unpleasant chemical odor, so they will not cause discomfort after treatment.To order the service of the destruction of the beetle, just call the phone number of the ECO-Capital sanitary company or request a call back. The specialist will answer questions, tell you about the services and help you choose the type of processing based on your specific situation.
If there is no opportunity or desire to deal with the mucoed on your own, use the services of special sanitary brigades. Employees of such services are experienced in the fight against insect pests and are aware of the habits of flour eaters.
Children and pets must be removed from the apartment during the work of exterminators, as well as food, clothing and children's toys should be hidden.
The work of the sanitary service consists of two stages:
Good companies provide a guarantee that the flour beetle will no longer appear in the apartment. Firms are now using fourth-generation insecticides that do not have bad smell and do not pose a threat to human health.
The most efficient and effective way to eliminate pests completely is to throw away all contaminated food, or better, get rid of all the cereals and pasta that are in the box.
It is worth remembering that sifting and sorting out bulk products will not help, because flour beetle eggs are so small that they cannot be seen with the naked eye.
Even thorough washing and blowing with air will not help get rid of all the masonry, so the beetles will soon appear again.If, due to various circumstances, there is no opportunity to ruthlessly throw away products, you can use the following methods:

It may seem that the process of pest control is quite complicated, but smaller measures will not lead to the desired result, because flour beetle egg clutches can be located in the most different places, it is better to protect yourself from the appearance of such unpleasant neighbors.
It is forbidden to use chemical agents against flour beetles, as all this will fall on food, which, after processing, can no longer be eaten. Poisoning can occur in humans and animals.
To prevent re-infestation by pests, the following precautions must be observed:
Knowing the types, signs and causes of the appearance, following the tips and recommendations for the prevention of infection, you can permanently get rid of these unpleasant little pests.
It doesn’t matter if large or small beetles appeared on the grocery shelves of the cabinet, the methods of dealing with them will be the same. It should be remembered that pests like wet, stale foods. Therefore, moisture should not be allowed to appear in the cabinets.
It is also advisable not to buy too many cereals if there are no containers to store them properly.After the contents of the container have been used, do not immediately add a new portion of food. Bank or Plastic container must be thoroughly washed and dried. This is done in order to destroy the eggs of the beetle, if they are there.
Pests of this species do not like the smell of bay leaf, garlic, chamomile, lavender. Dried herbs in bags should be laid out on the shelves to repel insects. Another interesting way there is a piece of metal wire, metal caps (for example, from a bottle) or nails placed on the cabinet shelves.
It is important to remember that metal products can rust, so they should not be wetted, but only wiped with a dry towel.
If the appearance of flour beetles could not be avoided, the products will most likely have to be thrown away. The dishes in which food was stored, as well as the room itself and furniture, should be washed with a bleach solution. Of course, you can sort out the cereals, and sift the flour.
But there is no guarantee that there will be no skins from molting bugs or eggs among the products. Since the beetles breed quickly, so all the work can go down the drain. Therefore, it is best to throw away infected cereals or feed them to birds. You can also carry out disinfection according to the folk method.
To do this, cereals and flour must be calcined in the oven at a temperature above 100 degrees or put in the freezer for a day.After this disinfection, the products can be eaten. That's just the properties of the products (mostly flour) may change. And few dare to eat such products. Therefore, it is necessary to disinfect the entire room:
It should be remembered that if not a single beetle is visible throughout the room, this does not mean that it is completely destroyed. It is possible that egg clutches will remain invisible due to their small size. So that the whole nightmare does not repeat itself after a couple of weeks, cleaning with disinfectants must be thorough and repeated.
If Khrushchaks are found in a living room, it is worth carrying out a general cleaning of all drawers and gastronomic containers. All cereals, flour, pasta and bakery products with pests are thrown away. The boxes and their storage containers are first thoroughly washed with water, and then treated with an vinegar solution (1 tablespoon of vinegar per 1 liter of water).
This product has a very unpleasant odor, so it is not recommended for allergy sufferers to use it. Instead, you can use a soda solution. It also repels bugs. In addition to boxes and containers, you will need to process the top cover of the ventilation shaft, window sills, baseboards and thoroughly rinse all the cracks in the kitchen.
To prevent the reproduction of beetles, it is worth storing all products in glass or metal containers that do not allow air and moisture to pass through.
It is not recommended to store cereals in paper or plastic bags. These materials are quickly gnawed by pests, so that it is not difficult for them to “run across” to another cereal.

The beetle itself has a black-brown color and a reddish abdomen. The insect belongs to the synanthropic species. It originated from the Mediterranean, and today has spread throughout the world. Khrushchak is not indifferent to various bulk products: cereals, flour, flakes, bran, starch.
Accordingly, it can appear in warehouses, grain storages and bakeries.At one time, the female lays about 200 eggs, from which larvae appear. During the year, the larva undergoes several molts, after which it becomes an adult. Flour beetles are insects of the dark beetle family, their size does not exceed 3-5.5 mm (with the exception of the large beetle).
The beetles have an oblong body, the color of the cover is reddish-brown. Distributed in all regions of our country. The reproduction of bugs is very fast. Only one female lays up to one thousand eggs in her life, and this is a very numerous offspring, it takes a little time and the pests form a whole colony.
If the conditions for the development and life of the beetle are normal, then there is a lot of food and optimal humidity, the larva pupates for 20 days, under adverse environmental factors - up to four months.
The bugs do not tolerate low temperatures at all, even the larvae die at -7 degrees and below.
Most often found in apartments the following types flour beetle.
Adults reach 1.8 cm in length, the body of the beetle is flat, black-brown above, with a red tint below. The larva is naked, cylindrical, 2.5 cm long, brownish-yellow.
The larvae do not have eyes, but there are legs with claws, on the posterior segment of the body there are two hooks and small warts, with the help of which they are repelled from surfaces.
The flour beetle pupa is white, with brownish protrusions, two spines are located on the posterior ring.Its flat brown body with a red tint has wings, but the beetle does not fly. The beetle has glands that secrete a highly odorous liquid to scare off enemies.
Small flour beetle larva is flattened. Its yellow body 6-7 mm is covered with short hairs, the head has flat shape. After 5-12 molts, she turns into a chrysalis.
The pupa is shiny, light yellow, with two tubercles at the end of the abdomen. At a temperature of 23-25 degrees, the entire development cycle lasts 47-56 days. At room temperature and relative humidity of 70%, beetles live a little over six months.
The body is dull-shiny, black or dark brown, the abdomen and legs are light. The beetle is similar to the small beetle, only it has a larger size.
The larvae are also similar, flat with hairs, only in the black beetle, the developed larvae are large (12 mm) light brown, development lasts a long time, about one year. They pupate without a cocoon, in caves.
Beetles appear at the end of summer, are predominantly nocturnal. The larvae of all types of beetles are called "meal worms", they easily move in the thickness of the products and on any surfaces, they are able to overwinter at a temperature of about zero.
The small hrushchak prefers to settle in warehouses, granaries, pasta factories, but is also found in apartments. Females penetrate into the slightest cracks in boxes, bags or bags of food and even into cracks in the walls, multiply under the wallpaper.
Plastic, paper or fabric gnaws through harmful insects. Due to the fact that the eggs are covered with sticky mucus, they stick firmly to any surface.
They choose storerooms as housing, kitchen drawers(scattered grits), places where there is a lot of dust, such as baseboards.This does not mean that the pests sit quietly in the products and do not crawl out anywhere, with a large number they feel like full-fledged owners in the apartment and crawl anywhere, only smooth vertical surfaces are beyond their power.
Wet, stale foods are preferred for tormenters, and if there are such places in the house, you may store pasta or cereals on the balcony, in a closet where there is no ventilation, most likely the place where the bugs spread is located there.
A large beetle needs to develop high humidity, and the small one lives safely in dry apartments with heating.
The flour-eater beetle is a frequent inhabitant of elevators, poultry farms, feed mills, and warehouses. From the elevator, the eggs and pupae of the beetle go unnoticed to the store where you buy flour or cereals. So the flour beetle gets into the apartment. Sometimes a beetle can start up in an apartment by flying in from an open window.
As a dwelling, a large Khrushchak chooses pantries, kitchen cabinets and drawers, bread bins and jars of bulk products, can live with skirting boards. The beetle multiplies rapidly, which leads to the destruction of all food supplies. The neighborhood of the Khrushchak does not bring joy to the tenants of the apartment and their pets, you need to get rid of this neighborhood as soon as possible.
Overwinters in the larval stage warehouses, often unheated, or in natural conditions. Pupation occurs in the spring in a variety of places: behind boards, in cracks, bags, etc. The pupa develops over 6-47 days, which directly depends on temperature.
Imago start to appear late spring or at the beginning of summer. The large flour beetle has a secretive lifestyle with nocturnal activity. En masse are going to light sources.
If the room is not heated, then the beetle gives one generation, and in a heated room - incomplete two generations. Egg laying occurs one by one or in groups on food, containers, walls.
During the day, one female is able to lay up to 40 eggs, throughout her life - up to 550 eggs. At favorable conditions molting of the larva passes up to 15 times, if there is a lack of food - up to 30 times.
Development lasts about one year under favorable conditions and two years under unfavorable conditions.The larvae are quite resistant to temperature fluctuations: for example, at a temperature of -5 ° C, death occurs within 70-80 days, at -10 ° C - within a month, but at a temperature of + 50 ° C, death occurs in an hour. When exposed to direct sunlight, they die within 10 minutes.
Common beetle small size, belongs to the group of dark beetles and reaches a length of no more than 3.5 mm. The body of the insect is from red to dark brown, depending on the species. Pests live in the most different conditions, including in rooms without heating.
They are especially active in warm apartments and homes with direct access to food. The breeding season for beetles takes a minimum amount of time. The female lays up to 1000 eggs at a time, so the number of insects is rapidly increasing.
In order for the beetle larva to develop in full mode, the air temperature should not be below 10 degrees, and the humidity level should be as comfortable as possible.
Only under such conditions will the larva move to a new stage of development - it will turn into a chrysalis. The less nutrients will receive it during the development period, the longer the pupation process will be (in some cases it can be delayed up to 4 months).
Not a single mealworm in the apartment (how to get rid of it - more on that below) is able to survive under low temperatures. It is enough to achieve a temperature of -7 degrees Celsius so that the larvae and adults die without additional pest control.
The main way the hruschak enters the apartment is to purchase products that have already been infected. Surely you had such a situation when, after buying groceries, you open the package, and larvae or bugs swarm there. Infection occurs in warehouses and storage facilities when storage rules are not followed.
A large beetle feels good in an attic with pigeons, lives and breeds, as it can feed on animal substances, such as the remains of feathers.
Once in multi-storey building with the help of birds where the beetle can't find suitable place for reproduction and food, penetrates into apartments through ventilation shafts.There are several ways for a pest to enter an apartment:
The eggs hatch into larvae and remain in food. Such flour and cereals cannot be used for food. Although the larvae are not poisonous, it is unlikely that anyone will dare to try such food. Someone does not immediately run to throw away spoiled food, but prefers to simply sift the flour, and sort out the cereal.
It is worth remembering that particles of larvae skins and their excrement will in any case remain in bulk products.
Flour beetles are practically omnivorous and damage many products - flour, bran, semolina, some semi-finished flour products. Khrushchaks do not disdain dried fruits, chocolate, buckwheat, glue, nylon and knitwear. Foods contaminated with flour become completely unsuitable for human consumption.
If the larvae can be removed by sieving, then the eggs are so small that they pass through the sieve, it is difficult to detect them, since they are covered with product particles.
Pests pollute groceries with skins of larvae, excrement, impregnate it with their pungent odor.The larvae can damage linen, there are reliable facts when the larvae of the flour beetle gnawed through burlap and tarpaulin. Flourish pests even bother pets, and in humans they only cause disgust. During the year, more than one generation of flour beetles develops, so you need to deal with them as soon as possible.
Contaminated products are completely unsuitable for human consumption. Larvae can be removed mechanically, but beetle eggs are difficult to see, sifting through a sieve will not help due to their small size. Eggs are covered with mucus, which helps the food product stick to it.
Pests infect food stocks of hosts with products of their vital activity, skins, dishes acquire an unpleasant aroma, which is difficult to get rid of.
