Prevention can be useful in the form of placing dry stocks in winter time on the balcony, in the summer - in the freezer.

3. Unsuitable storage container. The best option is to use glass jars with hermetically sealed lids. Limited air access has a beneficial effect on the long-term preservation of quality products. You can also replace containers with plastic bags, tying them tightly.

Have you found worms and bugs in cereals? How to get rid of it by sifting and heating

The processing option using a sieve is suitable only for small bulk products, such as semolina or flour. and, for example, buckwheat is usually sorted.

Each housewife for the time being is confident in her undivided power over own kitchen. One terrible day it is discovered on the ceiling or white windowsill uninvited guest from the order Coleoptera, and from now on small bugs in the kitchen are becoming more and more common, causing concern and disappointment. It seems strange where bugs come from in cereals that were just brought from the store yesterday.

What bugs are found in food?

There are only a few types of small insects in cereals and flour. They need to be identified in order to understand how dangerous the bugs in flour, pasta, and dried fruits are and what potential harm they can cause to humans.

The bread borer is a bug no larger than 3 mm in size. brown color. It penetrates into the apartment along with its favorite food - crackers, cookies, dryers - any hard baked goods, in which passages and excrement will become noticeable over time. In the house, the grinders will not disdain tea, dry herbs, they will try muesli, chocolate candies. They are noticed on light surfaces when there are already a lot of bugs in the reserves, and they fly into the light in search of a new habitat.

Small flour beetle - small insect(no more than 3 mm) red-brown shades. Khrushchak, or flour bugs, arrive at the kitchen in bags of flour and starch, and from there they are dispersed into loosely closed jars and boxes. Their culinary preferences are any types of flour, rolled oats, semolina, wheat. Flour beetles breed in the crevices of cabinets, so furniture also needs to be sanitized.

The red flour beetle is a bug with a light brown or reddish body no more than 2.5 millimeters long. Lives and reproduces in flour and cereal mills, elevators and grain warehouses, if there is soaked grain or rotten flour. Once it gets to your home, it will most likely die, since it does not like dry foods. It arrives in residential buildings with flour, cereals or in packs of cheap grain food for decorative rodents and rabbits.

A close relative of this species, the Surinam mucoed, differs, perhaps, only in color (dark brown).

Hazard to human health

Let's find out why insects in cereals are dangerous and how they can affect your health. Small black bugs in the kitchen do not pose a threat in themselves. The problem is a large number of eggs and voracious larvae, which reduce the nutritional value of the affected product. Their waste products may contain antigens to which the body will react by developing an allergy.

The most dangerous pests in this regard are flour and semolina, since their excrement is often indistinguishable from particles of these products and can provoke an allergy attack and exacerbation of asthmatic symptoms.

If there is a mucoid infection, then there is a high probability that mold will also get into the food (remember that mucoeds love high humidity). Cereals and flour with such pests can lead to poisoning or intoxication of the body, especially with prolonged consumption of spoiled groceries.

Reasons for appearance

There are several answers to the question of why bugs appear in cereals. Firstly, not only bulk food, but also packaged cereals, baking mixes and muesli may contain illegal migrants who made their way there from production warehouses and stores.

Secondly, eggs and larvae harmful insects often hide in cracks, hinges and other secluded corners kitchen furniture. If one invasion is suppressed, but serious disinfestation measures are not taken, small bugs in the cereals will appear again.

Thirdly, the presence of adult bugs in flour, cereals, and cereals indicates a dense population of the product with pests at different stages of development. Sifting flour through a baking sieve will help get rid of adults and larvae, but after a while the unpleasant neighborhood will resume due to ripened eggs in the same jar.

Signs of defeat

The invasion of grain pests causes great losses. If there are bugs in the cereal, they will definitely leave traces of their presence:

• thin cobwebs on the surface of flour and semolina and under the lid of the container;
• neat round holes in beans, chickpeas, peas;
• granular, dense excrement in dried fruits;
• small worms, empty cocoons of larvae found when washing cereals;
• lumps of several grains of cereal glued together.

Any of these “symptoms” is a reason to think about how to get bugs out of your kitchen cabinet and take the necessary measures.

Methods of disposal

Different products require different approaches. The answer to the question of what to do if there are bugs in flour is clear - throw it away. It is too likely that a lot of toxic and allergenic insect feces will be left behind.

There are several ways to get rid of bugs in cereals:

1. Washing. Bugs and larvae are lighter in weight than grains, so they float to the surface in water and can be easily drained. The legumes are soaked briefly in salt water and then dried on a towel.
2. Sifting on a sieve with medium holes will remove grains of insect excrement from the cereal. You can carry out this procedure before washing.
3. Heat treatment. Exposure to extreme cold or heat will leave small parasites no chance. It is enough to place bags of cereal overnight in freezer or take it out in frosty weather unglazed balcony. The heat works faster. It is enough to heat the cereals spread on a baking sheet for a short time at a temperature of 110 degrees Celsius to kill the entire living “population”.
4. Bait. For adherents of chemistry, there is a remedy for bugs in cereals that is safe for humans . Recipe: Equal amounts of borax, semolina and powdered sugar are mixed into the dough. The “delicacy” is laid out on pieces of cardboard or cellophane in kitchen cabinets. This mixture is especially effective against the flour bug.

When you have found how to remove bugs from cereals and other supplies, there remains one more important concern - preventing them from returning. Periodic cleaning and inspection goes without saying. To completely destroy the pest eggs, the cabinets are washed with a vinegar solution at the rate of 1 tablespoon per 1 liter of water. Sprigs of lavender, cloves of garlic or pyrethrum powder placed on the shelves will repel pests from the food, and Bay leaf can be placed in jars and containers; cereals do not absorb its smell.

If canvas cereal bags are soaked in a salt solution and allowed to dry, insects will not be able to lay eggs there.

Lifehack

The main way to prevent insects from outside from approaching bulk products is through sealed storage containers. They are not always at hand, but you can quickly organize them safe conditions for storing cereals directly in a factory bag. To do this you will need a cut from plastic bottle neck with lid.

The opened corner of the bag (provided that the rest of the bag is intact) is pulled through the neck and the edges of the bag are folded outward. A cork is screwed onto the neck over the cellophane - the express container is ready. It won’t save you from the voracious larvae, of course, but adult beetles won’t crawl in. Less temptation means fewer pests.

Black bugs and other insects in flour and cereals are a common problem. When they appear, they quickly infest everything, and a few days of delay can lead to a long time to remove the pests. They not only spoil food, but can also cause poisoning and allergic reactions. Pests can be brought from a store with low-quality products, and they also appear in places where products are improperly stored. We'll talk about methods of fighting bugs next.

Types of pests

Usually he eats bread, but he can also enjoy rice, buckwheat, tea, animal food and even an old book.

Mucoed

Prefers flour, cereals and grains. It is very voracious, despite its tiny size - 2 millimeters in length. The flour beetle larva is even smaller, so it is difficult to notice it right away: black dots found in flour are a sign of the presence of mucoed larvae in it. The beetle is very prolific, producing offspring up to 7 times a year. large quantities. Therefore, in just a couple of months, flour can turn into a breeding ground for these insects. The ideal environment for a mucous eater is high humidity and warmth.

Flour beetle

This small insect up to 4 millimeters long, reddish-brown. It multiplies rapidly, and settles not only in flour and cereals, but also in furniture and dishes. Breeding a beetle is very difficult, since it is unpretentious to living conditions and is hardy.

food moth

She looks like a simple moth. The length of its body does not exceed 1 centimeter. It is characterized by high fertility (over five hundred eggs in two weeks, from which caterpillars hatch). The moth devours cereal reserves at high speed. Her ability to hide, fly and disguise herself as dark objects makes her virtually invulnerable.

Weevils

They can appear in literally all products: cereals, flour, bread, dried fruits, fruits and vegetables. They look like small bugs, about 5 millimeters in size with a long proboscis. Weevils can fly, changing their location depending on changes in environmental conditions, and also easily climb walls. The pest produces offspring up to 6 times a year. They settle everywhere: remote corners of the kitchen cabinet, containers of cereals, bed linen, baseboards, cracks.

After disposal, it is necessary to wash kitchen shelves and cereal storage containers (if any) with bleach, soda or vinegar. After treatment, be sure to rinse the surfaces with water.

Heat treatment

All types of insects die at temperatures above +50 degrees. This can be either boiling water or steam treatment. This method is good for eliminating bug nests in baseboards and crevices that cannot be reached with chemicals and sanitation.

To remove bugs directly from cereals, you can fry them in the oven at a temperature of about 50-70 degrees for 20 minutes. Or put it in the freezer for several hours. Insects die at temperatures below 15 degrees.

When the larvae and adults are destroyed, it is necessary to thoroughly rinse the grains (beans, beans, nuts) with water and wait for the pests to surface. Then, drain the water and rinse the product again so that there are no larvae left in it. Flour and small grains after heat treatment It is better to sift through a sieve 2-3 times.

Chemicals

On open kitchen surfaces it's better to use special chemicals, which are sold in abundance in hardware stores. Just don’t buy it to fight the bug. simple remedies from cockroaches and ants. IN in this case needed specialized means, for example, "Antizhuk" or "Karbofos".

“Anti-bug” helps in the fight against any bug, be it cereal or wood, that damages windows and furniture. The drug is quite effective, but be sure to read the instructions before use, as it is toxic.

To remove insects, you can use “Rogneda” - a powerful antiseptic that can destroy weevils, mucoeds, ants and cockroaches.

One more effective means is "Lovin Fire Protection". Drug in as soon as possible kills the beetle, but it must be scattered in places inaccessible to animals, as it is a powerful poison.
