Latin: Thermobia domestica.
The adult is almost 2 cm long. It is gray with dark spots. The firebrat requires more heat than silverfish to thrive. At temperatures below 25 ° C it cannot survive nor reproduce. At 27 ° C the eggs hatch in 44 days and the full development to maturity takes almost a year. The firebrat survives at low humidity. Firebrats are found in kitchens and bakeries near heaters or other heat generators. The firebrat is, like the silverfish, omnivorous, with a preference for starches. Firebrats are exterminated in the same fashion as silverfish.
