6 legs, straight antenna, gray, crawling

Introduction:  All members of the order Thysanura have a teardrop/carrot/fish-shaped body and get the common name of bristletail because of their 3 long, bristlelike or taillike appendages on the posterior/rear end of their body. Firebrat is the common name for those species which prefer areas of high temperature, 90oF (32.2oC) and above. Firebrats are found throughout the United States and world.

Recognition: Adult body length, not including tails, about ½” (12-13mm) long. Wingless with flattened body. Shape teardrop/carrot/fishlike, tapering from head to rear, and generally covered with scales. Color uniformly grayish or grayish with numerous dark markings. Antennae long, threadlike.

Habits:  Firebrats prefer areas of high humidity, but temperature is the critical factor. They are typically found in areas where the temperature is 90oF (32oC) and above. Such places include boiler rooms, bakeries, hot attics, steam tunnels, around ovens, furnaces, fireplaces, hot water heaters and pipes, etc., with breeding areas possibly in adjacent wall voids, subflooring, etc. They are fast runners, prefer the dark, hide during the day, and prefer to hide or nest in tight cracks or crevices
