Little is known about adult biology. The only adults commonly seen are newly emerged adults and ovipositing females. Eggs are laid in batches of about 500 in dry cracks or crevices above the chosen larval media Other adults apparently live in a wild environment and their habits are largely unknown. They do not try to enter houses and are usually not a problem. In 15 years of investigating this insect, I can remember only one complaint about adults entering a residence.
