Why do moth larvae spin silk?

The larvae spin silk into cocoons and store wool, upholstered furniture, fur, carpets, blankets, fishmeal, chemical wool, and cotton-blended fabrics for the larvae to feed. The larvae are mostly found in clothing storage rooms and in the cracks of upholstered furniture. The clothing moth has a very weak constitution and does not fly far, which limits its range of activity.

In particular, textiles are stained with food or other contamination, and clothes moths can be seen on the collar or folds of clothing. The most appropriate way is to dispose of the laundry when it is time to put it away. Remove all laundry from the closet, clean the folds, and expose them to the sun for a few hours.

Dry cleaning and wet cleaning should be ironed and sealed in a plastic bag. When the wardrobe is empty, spray the wardrobe with Taosi pine, etc. After treatment, put the clothes back, close the wardrobe tightly, put some mothballs (naphthalene pills) on the upper layer (put in the required amount according to the instructions), remember not to put the clothes with sludge in them, because the smell of sweat is more likely to attract clothes moths.

Clothes moth. The larva is a small white caterpillar.

Hidden in a silky bag or mesh (called a tube nest), a spindle-shaped silk bag with cement attached to it can be seen on the wall, and a larva with a dark brown head is inside. Adults are light yellow and photophobic. If it is pressed to death, it will emit an unpleasant odor.

The body of the adult clothes moth has shiny golden scales, the head is golden red, and the antennae are darker than the rest of the body. Female moths are slightly larger than male moths. Adult females can live for 3-4 weeks and lay 35-50 eggs on the surface of the fabric during mating.

The eggs are white, soft and round, hatching into larvae within 5 days, and may also extend to 20-25 days due to temperature. The larvae are white, creamy, shiny, fully mature larvae about 10-12 mm in length. The larval stage lasts for a total of 35-40 days and can be extended to 2-3 years, depending on temperature and grain**.

The larvae generally pupate in silk.

This is the larva of the clothes moth.

The larvae of the clothes moth spins silk and weaves bags, and is a small brown caterpillar that usually hides in a self-woven silk bag. On the walls can be seen a spindle-shaped silk bag with a dark brown head inside. Adults are small light yellow or brown moths that are afraid of light and prefer darkness.

The larvae are very harmful and will eat wool, soft furniture, fur, hair, carpets, blankets, fishmeal, chemical fibers, cotton blends and other textile items, while cotton clothes do not like to eat. The larvae are often hidden in clothing storage rooms and in the cracks of upholstered furniture. The clothing moth has a very weak constitution and does not fly far, which limits its range of activity.

He is especially fond of textiles and clothes that are stained with food or other contamination.
