In some cases, during the period of taking a shower, it is possible to find an unpleasant gift under your feet - a small creature unpleasant in appearance, similar to a mustachioed beetle.

Often, unknowingly, these creatures are mistaken for beetles, millipedes, even silverfish (although there is no resemblance to the latter in appearance at all). But this is just ordinary woodlice (armadillo), absolutely harmless, but this is no less an unpleasant creature.

In the article, we will look at where they come from and where they live, what are the reasons for their appearance, as well as why they often wind up in the bathroom of a house or apartment, and how to get rid of them.

Brief definition

Woodlouse is a small crustacean, whose dimensions are on average 10-12 millimeters., however, in some cases, individuals are found larger, up to 18 millimeters. The body is gray, in some cases dark, almost black, although there are also practically white specimens, the carapace is 7-segment, slightly plastic, rounded. Each segment has its own pair of legs (7 pairs of legs in total).

On the small head of the crustacean, there are two pairs of antennae (one pair is long, noticeable, and the second is underdeveloped), the eyes are placed on the sides. At the end of the body there are tactile organs, similar to 2 small ponytails-appendages.


In nature

The habitual sphere for this crustacean is wildlife., and can often be found in the following places:

  1. under fences, stones, foliage, stumps;
  2. on roadside;
  3. at the bases of the walls overgrown with grass;
  4. in landfills;
  5. in greenhouses;
  6. in loose soil.

Woodlice feeds on plants, both decaying and active, for this reason, to a certain extent, it can be a pest of civilized plantings. Although the crustacean does not disdain unpeeled plants, which can serve many gardeners.

In living quarters

Why do they appear in residential buildings? Since moisture is the main thing for woodlice for a comfortable existence, it can also settle in damp rooms: sheds, basements, warehouses. Once in the apartment, she will certainly prefer those areas where there is more humidity:

  • pantry;
  • bathroom;
  • restroom.

As already mentioned, human housing is not considered a favorite area for woodlice to live, for this reason they are rather unique "guests" in the apartment.

Causes of occurrence

In the apartment

The appearance of wood lice is, as a rule, the result, but the reason is the favorable conditions created in the apartment for their life. Darkness, humidity and warmth are the 3 main conditions that cause these insects to appear in the room. What else attracts wood lice to human housing:

  1. wet laundry accumulated in the bathroom;
  2. the presence of plants in the housing that require abundant watering;
  3. musty debris and food leftovers;
  4. old paper, as well as books that have not been opened for many years;
  5. rotting plants;
  6. dirt in the hidden corners of the apartment.

In a private house

Woodlice in the home arise in search of comfort. What attracts crustaceans in a human dwelling:

  • Constant humidity. If a pipe passes through the room or there is constant condensation in the batteries, wood lice will choose a home existence.
  • Food Source Food leftovers and rotten leftovers are a feast for crustacean pests.
  • Wet ground Greenhouses and greenhouses are ideal habitats and breeding grounds for wood lice and other parasites.
  • In garages, mold and mildew often develop, which attracts centipedes.
  • A private well or a water column attracts crustaceans if the old pipes are leaking. In puddles of water, moldiness is divorced, and the place forever becomes an oasis for wood lice.
  • In the season of heavy rain, the basement and cellar are flooded with water without proper treatment. The moisture settles on the walls of the building, and crustaceans instantly start.
  • The presence of small defects in the roof leads to the fact that water flows into the attic during the rainy season and will be an impeccable place for woodlice to live in the house.
  • In autumn, woodlice appears on the site under fallen leaves, covered with branches and decorative stones.

Where do they breed?

Quite often, the owner of the dwelling does not even assume about the presence of uninvited visitors. Woodlice prefer moist air and hide well... They lead an intensive lifestyle only at night. Most often they can be found in places where damp rags are stored, in black corners, under tiles or baseboards. If water is regularly dripping from the sewer pipes or you are flooded by neighbors, wood lice will soon appear.

For the life of these insects, special conditions are necessary, contained in a significant humidity of the air, the absence of light. Under such conditions, they reproduce quickly and live well. After they can form a feeling of insect invasion, but this does not last long.

What are the first signals of appearance?

At home wood lice are often found in pots of houseplants, eventually exterminating them... They are especially partial to sultry types. It is not at all difficult to recognize the presence of this insect in the soil of a houseplant. In the course of life, woodlice significantly compacts the soil in the pot.

If you see such a manifestation, instantly loosen the soil, otherwise the roots of the plant may die from oxygen starvation.

The appearance of snow-white larvae on the surface indicates the presence of a parasite.

How to get rid of them?

Finding wood lice in your apartment:

  1. The first thing to do is to find the zones of their penetration. These can be various gaps in the floor and walls, or soil in pots of houseplants.
    • all cracks must be closed using hermetic means;
    • it is more correct to dig up indoor plants and transplant them into a different soil;
    • the old soil must be put in a plastic bag, fastened tightly and taken to the trash.
  2. The next step to be taken:
    • thoroughly check the water supply;
    • eliminate all problems;
    • clean out clogged pipes and repair leaking pipes.

Woodlice already in the house can be eliminated by some methods.

The most popular and effective is the use of chemicals. There are various substances, gel-like in consistency. They cultivate all corners, crevices, areas near baseboards and hard-to-reach areas. The result is achieved in about 2 days. In addition, in order to eliminate wood lice, salt and a solution of boric acid are used. They act very quickly and efficiently and, unlike chemical-based products, their use ensures absolute safety for human well-being.

After eliminating all wood lice in the apartment, it's time to move on to the next step. This step is considered the implementation of a general cleaning. Avoiding dirt as the root cause will greatly reduce the possibility of secondary woodlice infestation. Thus, in a few steps, it is possible to simply eliminate all wood lice in the house. But it must be remembered that getting rid of it constantly is much more difficult than preventing the occurrence.

Prevention of the appearance

For the purpose of baiting, it is recommended to use folk and chemical methods of fighting arthropods. However, it is more correct to implement measures to prevent their occurrence at home.


  1. Keep residential and other buildings clean.
  2. Repair the skirting boards, walls and panels so that no extra holes are left.
  3. Control the degree of moisture in private housing, buy a climate control device.
  4. Do not store waste, but instantly take it outside the boundaries of the site.
  5. Eliminate pipe leaks, check the gaskets, the reliability of the sewerage system and water supply.
  6. Clean the ventilation in the apartment, garage, cellar, summer kitchen regularly.
  7. Fertilize plants using folk methods, so that chemistry does not harm the roots.

Choose an acceptable method of your choice and get rid of wood lice forever.


An ordinary wood louse is an absolutely harmless creature. She does not bite, does not destroy food. However, with a large number of their houses, all indoor plants are threatened, and it does not matter which room they are in. In a suburban area, woodlice can cause damage to agricultural plantings, eating up roots and leaves. For this reason, a person does not tolerate the neighborhood with woodlice and resorts to measures to eliminate it.
