This pest is common indoors on the East Coast, and is also found indoors in the Midwest and Pacific Coast. It is found indoors in warm, humid areas such as basements. The eggs are deposited in crevices or under objects singly or in groups of 2 or 3. The female deposits 1-3 eggs per day or at irregular intervals of up to several weeks depending upon availability of food. Eggs hatch in 43 days at 72 F and in 19 days at 90 F. Females may reproduce at 3-4 months of age.
Scales develop in the third instar.
Silverfish may pass through up to 59 instars in their lifetimes. This species is common on the East and West Coasts and in the Midwest. It lives indoors, often infesting attics, particularly if the roof is made of wooden shingles. It may be found outdoors in summer. Its life cycle is similar to that of the silverfish but not as limited by temperature and moisture.
