Reasons and what to do if a mole starts up in walnuts

What to do if moths start in walnuts? Every person faces such a problem in his life. The moth settles not only in them. It often affects cereals, flour, dried fruits, clothing, furs, and carpets. I would like to save the product and get rid of the pest. If the walnuts were kept in their shells, then they can be saved.

Description of the pest

The butterfly is about 2 cm long. Belongs to the order Lepidoptera. The wings are brown-gray. There is a pair of antennae on the head. Has 2 pairs of legs. The insect lays eggs in cereals, dried fruits, flour and other places. The eggs are small, up to 0.5 mm in diameter, it is almost impossible to notice them. From them, larvae appear, which cause the main damage to products. After the larval stage, the moth transforms into a pupa and then into a butterfly.

Important! The main damage to products is caused by butterfly larvae.

Moth damage

The butterfly itself does not harm the walnut. She lays eggs in the bag, but does not feed on them. When the larvae hatch to the surface, they contaminate the surface of the shell with feces, chitinous particles. If the fruit is in the shell, then you can save it.

If they are kept clean, they will most likely have to be disposed of. The insect infects food at any time of the year.

Foods spoiled by moths can harm the human body:

  • intoxication;
  • poisoning;
  • decreased immunity.

Causes and signs of appearance

Moths start in the kitchen for several reasons:

  • bringing food contaminated with insects into the house;
  • storing nuts in a room with high humidity;
  • rare airing of the room;
  • finding an open container next to the window, bringing in from neighbors.

To determine if there is a moth in the house, you need to pay attention to certain signs:

  • a small butterfly flies in the apartment mainly in the evening;
  • stirring is observed in cereals or nuts;
  • detection of larvae in nuts;
  • the larvae crawl onto the walls.

Important! Moth appears in places where old cereals, nuts or dried fruits are stored for a long time.

What to do if a mole starts up in walnuts

Don't wait for the moth to hit all the food in the house. As soon as the first signs appear, you need to immediately begin to fight the insect. In order to completely exterminate the moth population, all affected products are initially thrown away, then containers and furniture are processed.


Chemicals are used to combat the butterfly not only in products, but also in carpets, clothing, and fur things. The most effective drugs are:

  • Raptor. Apply to the surface of wooden furniture. The smell scares off butterflies;
  • Armol. Spray used to treat furniture surfaces;
  • Combat. They are used in hard-to-reach places where moths and their larvae are hidden;
  • Antimole. Spray on fabrics and clothing that are near the insect's habitat.

The nuts themselves are not processed with the means. You can save them only if the moth was discovered quickly and the nuts were in the shell. To do this, the walnuts are washed in warm water, drained, and calcined in an oven at 100 ° C for 2 - 3 minutes.

Important! Chemicals are absorbed even through the dense shell of the fruit, they cannot be processed with them, this will lead to poisoning.

The use of folk methods

Folk remedies are suitable for those who do not want to resort to the use of chemicals. They are prepared on the basis of herbs, the smell of which is difficult for the moth to tolerate. The best recipes are considered:

  • Bay leaf. This method serves not only to fight, but also to prevent moth infestation. Leaves are laid out in cabinets and containers where the insect has started.
  • Traps are prepared from flour and boric acid. The ingredients are mixed in a ratio of 1: 3, then poured into a container and placed in a cabinet, where the larvae and adults fall.
  • The walls of the closet and furniture, where the insect has wound up, are greased with lavender or fir oil. In addition, dry branches of these plants can be laid out in the shelves.
  • The tobacco smell effectively repels moths. To do this, crumble several cigarettes on a plate and put them in the room where the pest lives.
  • Orange peel. After peeling the orange, it is laid out inside the furniture.
  • To kill the eggs, they wipe the shelves with ammonia.

Important! Folk remedies not only relieve moths, but are also means of prevention.

Features of prevention

To prevent the appearance of moths in an apartment, preventive measures must be followed. This insect appears indoors at any time of the year. As soon as the conditions are optimal for her in the room, she immediately settles in cereals, dried fruits or nuts. To prevent infection, you need:

  • Wipe the walls of kitchen furniture with food vinegar 2 times a year. The strong smell of the solution will be partially absorbed into the furniture and scare away the pest.
  • Do not create clutter in the room. Clean up and sort out periodic old things. Throw away and remove old clothes, spoiled dried fruits, old cereals.
