What to do if there are book lice in the furniture

Book lice (Book lice, Book louse) belong to the order of rodents (Order Credential), there are more than 2,000 species in the world, and the body color is white, pale yellow or gray.

It feeds on organic matter such as molds and fungi, and will cause damage to fur fabrics, specimens and books when it occurs in large quantities.

It can breed 6 to 8 generations a year, and can reproduce automatically. The eggs hatch into larvae in 6-21 days, and then become adults after four molts, with an average lifespan of 175 days. It mostly appears in damp, dark, poorly ventilated environments, in paper and books that are not often used, and eats away at the edge of the book and the paste used for mounting, and even mold on the paper.

The environment is too humid to cause a large number of book lice to multiply, causing harm, with the tiny size of the book lice (body length 1-5 mm), a small number of book lice gnaw on the traces of paper, it is not easy to see with the naked eye.

When the newly decorated house is often due to high humidity (damp house), high temperature, poor ventilation, book lice can occur in a large number of short time, at this time book lice grow on the surface of the wet wallpaper and the floor, wood and other gaps of fungi, mycelium staple food, in the environment humid, high temperature, poor ventilation, conducive to the growth of fungi, so promote the harm of book lice.

The most effective way to control book lice is to keep the house dry (especially the decoration is often limited due to the construction period, there is not enough drying period after mud work, and the wood is immediately followed by construction - the house is too wet), such as a relative humidity of 50% Some insect pests are relatively difficult to produce. For example, the use of dehumidifiers and dehumidification packs, the use of vacuum cleaners to clean the food is not conducive to the acquisition of food, and the ventilation is enhanced when the humidity is low. When none of the above methods can inhibit the treatment of the extractable agent (some agents have both antiseptic effects).

Spraying with 2% formaldehyde can be inactivated, but it is also harmful to the human body, so use with caution!

Book lice can be removed in the following ways:

1. Aluminum phosphide and dichlorvos mixed fumigation (mixed method).

According to the provisions of the use of the agent to calculate the dosage, in the grain surface and ventilation holes placed aluminum phosphide tablets, each ventilation hole does not exceed 2kg, other agents placed on the grain surface, around the warehouse can be appropriately increased dosing. Then, spray the sack with dichlorvos dilution and hang it evenly in the compartment space. For the first few days, the circulation fan is not turned on, and after about 3 days, the fan circulation is turned on (at this time, the phosphine concentration basically reaches the highest value, and the active component of dichlorvos basically volatilizes into space).

Through circulation, dichlorvos and phosphine gas act on pests and insects at the same time to achieve the effect of superposition and synergy. This method is suitable for cases where the density of book lice is high.

2. Simple aluminum phosphide fumigation method (fumigation method).

Aluminum phosphide circulation fumigation is used alone. This method is suitable for cases where the density of book lice is low.

3. Dichlorvos space fumigation (suspension method).

The dichlorvos dilution is evenly sprayed on the sack or blanket and other equipment, and then evenly hung in the space of the warehouse, relying on the fumigation and diffusion of the agent to achieve the purpose of killing insects. This method is suitable for the situation where there are many book lice, and they are distributed in the space above the grain surface, and there are no other pests.

4. Dichlorvos attachment burial method (burial method).

Spray dichlorvos emulsion directly on newspaper balls or bricks, bury them in the grain pile (10 30 cm below the grain surface), take them out regularly, clean up the insect corpses, respray the liquid medicine, and place them in the grain pile. This method is suitable for the situation that there are many book lice in the grain pile, and there are many impurities that are not easy to penetrate, and it has the dual role of trapping and prevention.

You can get rid of lice disease by buying it and putting it in.

Book lice are rodents of the family Book lice, which are the main late-stage pests, reproduce 3-6 generations per year, have relatively strong vitality, overwinter with eggs, crawl quickly, like high temperature environment, often inhabit more than one foot of grain surface or gather near warehouse doors and windows; When a large amount occurs, it is easy to cause local fever of stored grain, and has strong resistance to drugs and other fumigants. Use a special liquid net welling insecticide with smoke fumigation, dilute the insecticide with water 20-30 times, spray the surface of the insect-infested wall furniture, and then fumigate with smoke, and the liquid sanitize penetrate to kill the eggs, and the effect of the smoke is not in place, such as the ceiling high, etc., as a backup for fumigation in place.

Pinch it to death, or you want to keep it?
