Clover fish, also known as scissors fish, carp, whitebait, anchovy and so on. , a primitive wingless insect, belongs to trilobite family, with about 250 species known all over the world and more than 20 species known in China. This insect is not only a moth stored indoors, but also an important pest of archives, books and cultural relics in libraries around the world. In China, the common species in libraries are Chlamys farreri, Chlamys farreri from Taiwan Province Province and Chlamys farreri.

The breeding grounds of clothing fish are bookcases, bookshelves, book bundles, floor seams and gaps between old books. Carp has negative phototaxis, so it often hides in the dark and comes out at night. Carp is sensitive to temperature and humidity. The suitable environmental temperature for carp breeding is 65438 06℃ ~ 30℃, and the relative humidity is 75% ~ 95%. When the temperature and humidity are not suitable for the breeding of sweater fish, clothing fish will migrate to an environment with suitable temperature and humidity. Carp has a wide range of recipes, such as grain, finished grain, Chinese herbal medicine, organic matter in indoor dust, photos, paper, paste, glue, cotton cloth, animal fur, silk fiber, human dander, etc., all of which are rich in protein, sugar and trace elements. The feeding characteristics of Armillaria mellea larvae and adults are similar, and foods rich in sugar are more attractive to them.

Prevention and treatment

Because of its omnivorous diet, many hidden places and fast action, it is difficult to prevent and control sweater fish. We should mainly focus on the following points:

(1) Do a good job in environmental sanitation, clean up rotten and damp articles, and clean the surface that is not often exposed, thus reducing the spawning habitat and number of long-haired fish and reducing the number of insect mouths.

(2) Control temperature and humidity. The suitable temperature for the development of long-haired fish is 22 ~ 28℃ and the humidity is 75 ~ 95%. Therefore, it is best to avoid the optimum temperature and humidity for the development of hairy fish.

(3) Around the doors and windows, around the legs of filing cabinets, sprinkle some powdery pesticides, such as Baichongling. Liquid pesticides can also be used. This can cut off the activity and storage route of woolly fish and reduce its damage area and scope.

(4) If necessary, you can put some insect repellent. There are many drugs on the market, which are mixed, so we should choose products from reliable manufacturers.
