Habits: Feed on microscopic mold growths. Need damp environments which favor mold growth. Some species may develop wings under some conditions but most are wingless. Although called ‘lice’ Psocids are not true lice and do not bite humans or suck blood. Often transported in or on paper goods and cardboard which was stored in a damp environment.
Habitat: Damp, dark environments
Prevention: Store paper and cardboard in dry environments to prevent mold growth.

Size: Black carpet beetle up to 3/8 inches. Other species more oval and smaller
Habits: Feed on a variety of animal and dried plant products including wool, feathers, and silk. The black carpet beetle is more of a scavenger feeding on lint accumulations behind baseboards of older homes. Other carpet beetles can be found on flowers such as Spirea outdoors in the spring.
Habitat: Any dark area containing susceptible food sources.
Threat: Can damage fabrics and museum pieces containing animal products.
Prevention: If storing susceptible items for extended periods, consider cold storage. Unlike clothes moths, dry cleaning will not prevent infestation.
Color: Golden-buff with or without three small, dark spots
Size: 1/2 inch wing spread
Habits: Eggs are laid on fabrics containing animal products such as wool, felt, feathers, furs, etc. The larvae food on the fabric. The case-making cloths moth larvae make small, white, silken cases in which they live. The cases a most commonly formed in seams of the fabric. The webbing clothes moth larvae simply make silken webbing over the areas in which they feed. Cocoons are made on the fabric. The adults are weak fliers.

Threat: Can damage furs, wool rugs, wool clothing, felt hats and similar products
Prevention: The newly hatched larvae need soiled fabric on which to feed. Dry cleaning susceptible items before storage helps prevent infestation. Furs should be stored at 40ºF or colder to prevent infestation. Moth balls or flakes can retard infestation if the vapors are confined in storage chests or other containers.
