Why do black and brown bugs appear in cereals: reasons for their appearance

Bugs in cereals
Many housewives often have questions: “Why do black and brown bugs appear in cereals?”, “What are the reasons for their appearance?” Here is the answer:

Insects are usually brought from the store with purchased products.
Even your neighbor, without knowing it, could lend you contaminated cereals or flour.
Also, amateur fishermen specially breed mealworms to use them as bait.

Worth knowing: The pests themselves do not travel long distances, only along with packaged products.

It's hard to see them in the store because they are so small. In addition, there may be larvae in the cereal or flour - they are not visible at all.

But how do they get into store packages? The reason lies in non-compliance with storage rules and weakening of sanitary control in production. To preserve food in warehouses, minimum air humidity is required. If this indicator is violated and the humidity is 50% or higher , then the risk of insect damage greatly increases. Moreover, if they are packaged not in small containers, but in bags with the subsequent sale of products by weight.

Insects appeared in bulk products

Infection with flour bugs occurs due to non-compliance with the conditions of production and storage of flour or cereals. In this case, there is often an increase in humidity levels and insufficient quality of product processing. Usually the critical limit of humidity is considered to be 14%. At higher values the beetle may get infested.

Most often, loose flour becomes infected, since it is stored in the open air, which means that pests can lay eggs. It is almost impossible to determine the presence of larvae, since they develop inside small white shells. For this reason, it is recommended to purchase factory-packaged products. However, there is also a risk that flour bugs will appear, since some types of insects gnaw not only products with a dense structure, but also the walls of plastic packaging.

If they are severely infested with flour beetles, they should be thrown away, as eating them is dangerous to health.

Bugs in the croup
If even one bug catches your eye, then you need to act immediately, without putting the matter off for a long time. It is quite possible that all the cereals are already infected with larvae and in a few days there will be hundreds of times more of them. How to get rid of food bugs in cereals?

It is quite difficult to completely get rid of them, but you still need to do everything possible to destroy them. What needs to be done? Here are effective ways:

Review all supplies , find the source of infection and all affected products, and if there are a lot of bugs, the best solution is to throw away all the cereals and flour without regret.
If there is a slight infection, you can try to save the cereals - put them in the freezer for at least a week or place them in a hot oven at a temperature of about 50°C for 2-3 hours (without packaging).
If all else fails, you will have to use chemistry . The best remedy for killing bugs is D ichlovos. This product is smelly and harmful to our health. Therefore, you need to take precautions when working with this drug; they are indicated on the packaging. There are other drugs, for example, Raptor .

Before using it, you need to put the flour, which strongly absorbs all odors, into a tight bag and tie it well. You need to do the same with the rest of the products.
Place napkins moistened with camphor alcohol in the corners of the cabinet.
Also put them on shelves in the corners and close the doors for 3 hours . You need to do this 3-4 times a week until the bugs disappear completely.

Pest control is good, but ongoing prevention can be done to ensure the insects never get infested. Read more below.

Chemicals

If the beetle has infected all the products, then it is much more advisable to treat the infected room with insecticides. Below are the drugs that are used to combat small and large flour beetles.

Phosphine

A gas produced by mixing phosphorus with hot alkali. In agricultural stores it is sold in the form of blocks for fumigation, containing substances that synthesize this chemical element when heated.

Phosphine affects the nervous system and disrupts the metabolism of insects, including the flour beetle. It is also effective against other pests.

Expert opinion

The connection is also dangerous for humans. During the fumigation of the room, you must leave it and return only after 10 - 12 hours. The treatment area must be well ventilated.

Borax

Relatively safe product. Effective against adults, but not against larvae. Borax is mixed with flour and sugar and placed in areas where the parasite is expected to live. When ingested by a beetle, the substance causes severe dehydration, resulting in death.

Ozone

Flour beetles do not tolerate air saturated with ozone. Therefore, ionizers are used to combat them. They are left on for several hours in the room being treated.

Ozone is also toxic to humans. Therefore, the room must be well ventilated before using it.

Insecticide solutions are also used against the beetle. However, it is strictly forbidden to use them for food processing - you can get poisoned. Using solutions, the pest is removed from the seed.

DO NOT STOCK:

You shouldn't stock up on large amounts of food.

Storing cereals closed STORE
GREATS CLOSED:

Quality departments monitor the purity of each batch of products sent to the counter. However, an unfair attitude towards this stage of production is present and bears fruit - bugs appear in the customers’ kitchen and infect other products.

The main way for a beetle to enter an apartment is to purchase products that have already been contaminated. Surely you have had a situation where, after buying groceries, you open the package, and there are larvae or bugs swarming around there.

Once in a multi-storey building with the help of birds, where the beetle cannot find a suitable place for breeding and food, it enters the apartments through the ventilation shafts.
