Hay-eaters rarely settle in an apartment. Mistresses most often do not even know what this pest looks like and where to look for its habitat. However, if he has already wound up in the house, getting rid of him is very difficult. Let’s figure out what kind of insect it is and how to effectively deal with it.

Species features of the pest

The detachment of hay-eaters has more than five thousand varieties. These are small bugs about 1 mm in size, the largest species — no more than 5 mm. The pest is easy to distinguish by the peculiar structure of the head. The massive upper jaw is typical for gnawing. On the lower there is a solid process directed forward with teeth. It looks like a small proboscis. The beetle breaks and crushes food with them. The body is oval, flat. You can see in more detail in the photo below — the fact that you will know the parasite «by sight» will help determine the right means of how to get rid of the hay-eater.

Most species have wings or their vestigial remains. Despite this, pests rarely fly, but move very quickly. In nature, they live in warm, humid places: in forests, in glades, in swamps. They feed on plant dust, parasitic and mold fungi, plant residues, and the smallest organisms. They are unpretentious in food, so they find food everywhere.

For the inhabitants of our country, two types of pests are dangerous: book lice and dusty hay eaters. They are not much different from each other, only the latter can fly. They start up in damp warm corners: bathrooms or bathrooms. They love new buildings, especially block ones, for high humidity and the opportunity to feast on casein glue, tile grout, etc. In the kitchen they prefer cabinets with cereals and flour, and other supplies.

Books are especially attractive to harmful insects. Previously, a paste was used to make bindings, which they love very much. Therefore, colonies of bugs live in any book storage or library. Together with books they are brought into the house.


This is not the only way book lice appear in an apartment. They are brought with infected cereals or flour, other products.

Pests enter the dwelling through ventilation shafts, small gaps between the wall and a window or doorway, any, even the smallest gap. They settle in secluded places, prefer the wettest. The presence of mold provides them with a food base. It is necessary to start fighting them immediately after at least one individual has been seen. It must be understood that the bugs are small. Most often, when they catch the eye, their numbers are already very large.

How to get rid of a home hay eater

Getting out uninvited neighbors is not easy. First you need to determine the scale of the invasion. To do this, you need to examine all the places where beetles can settle. First of all, this is a home library: books and shelves. In the kitchen, you need to look in bags or jars with bulk products and inside cabinets. If there are rooms with mold, these are the best conditions for «tenants». They settle on engineering communications, in ventilation shafts.

You can find bugs in any room. On the ground floor or in a private house, pests live comfortably under the floor covering. A small gap between the substrate and the laminate or linoleum is quite enough for them. There are also a lot of them on the upper floors, especially if the roof leaks. It must be understood that it will not be possible to find all the nests. You can only determine the areas where processing is needed.

Special processing

If there are a lot of them, it is better to contact specialists immediately. They know how to get rid of hay eaters in an apartment. The most effective techniques are cold or hot fog. The suspension is sprayed using special equipment. The smallest droplets penetrate literally everywhere, settle where it is impossible to process in another way. They are saturated with a poisonous substance that quickly kills the beetles.


Turning to specialists is effective, but not always possible.

Self processing

In order not to make a mistake in the choice of means, you need to make sure that there are no errors in identification. Book lice are the smallest, all other harmful varieties are two to three times larger. In addition, they do not bite, so there are no bite marks. You can suspect the presence of hay beetles by small dots of excrement and a soft knock, similar to the quiet ticking of a clock when they break their food with their proboscis.

Most often, individual specimens come across in the kitchen or near books. You can get rid of them only with the help of an insecticide. Means based on permethrin and other poisons will help, for example, «Executioner», «Flicid», «Akarin». It is important that the drug destroys not only adults, but also eggs. Otherwise, after a while the colony will be reborn. Let’s take a step-by-step look at what you can do at home.

Action algorithm

  1. We take all the books off the shelves. If there are few of them, close them in plastic bags and put them in the freezer for a day. An important point: this should not be done with antique folios, there is a threat of their damage. You can treat books with insecticide, but that can also ruin them. We take the volumes out onto the street or onto the balcony, open them, place them on a film and spray them with a spray bottle. Leave open for a day, then remove in place.
  2. We vacuum the shelves, immediately shake out the bag. We treat with insecticide, wait for the time indicated in the instructions. We wash them with soapy water, wipe dry.
  3. We wash textiles with traces of the presence of beetles at the highest possible temperature. We dry in the sun. Steam and iron with a hot iron. Not all textiles are washable. Then, if possible, we place it in the freezer for a day or treat it with special disinfectants such as Trilox, Hypostabil or Sulfochlorantin-D.
  4. We treat the room with insecticide. This is not necessary, but desirable, given that the insects are very small and difficult to see. Close windows, take pets out. We spray the aerosol on all surfaces from a distance of 30-35 cm. We leave the room, close the door tightly. We are waiting for the remedy to work. Then we ventilate the room and wash with soapy water everything that the insecticide has come into contact with.

In the kitchen, special requirements must be observed. Infected products are immediately discarded. They are contaminated with the excrement of dust lice. Storage containers are thoroughly washed and put in the freezer for a day. A good result will give exposure to high temperature, if this does not spoil the jars. Then the entire room is treated with an insecticidal preparation with the obligatory observance of safety instructions.


Insect Prevention Measures

In all recommendations on how to get rid of a hay eater at home, it is emphasized that preventive measures must be taken after processing. Otherwise, the population will return, restore its numbers and even increase.

Preventive measures

  1. Reduction of air humidity to normal values. New individuals hatch from eggs only in conditions of high humidity. Its decrease significantly reduces the number of harmful beetles. An effective ventilation system needs to be repaired or installed.

  2. Destruction of mold and fungus. This is the best food base for insects. All moldy areas in the bathroom, bathroom and other places should be cleaned and sanitized.

  3. Maintenance of engineering communications in good condition. Even the smallest leaks and leaks must be eliminated in a timely manner in order to prevent the formation of constantly weeping areas.
  4. House plant care. A lot of moisture in pots and trays attracts dust lice.

  5. Maintain order in storage systems. Do not litter the rooms with old books or things. You need to regularly disassemble your stocks, get rid of trash and deal with dust.


It is difficult to notice dust lice, even when they already live in an apartment. But if they caught your eye, you must immediately decide how to get rid of hay-eaters. The most effective way is to call a team of exterminators. They will destroy the entire population of bugs along with the eggs. It remains only to carry out preventive measures so that uninvited neighbors do not settle in the house again.
