The Firebrat (Thermobia domestica, sometimes listed as Thermophila furnorum) is a small insect (typically 11.5 cm) similar to the Silverfish, both in the order Thysanura. Firebrats prefer higher temperatures and require some humidity, and can be found in bakeries and near boilers or furnaces. They feed on a wide variety of carbohydrates and starches that are also protein sources such as dog food, flour and book bindings. They are distributed throughout most parts of the world and are normally found outdoors under rocks, leaf litter, and similar, but are also often found indoors where they are considered pests. They are primarily a nuisance inside the home or buildings, as they do not cause major damage, though they can contaminate food, damage paper goods, and stain clothing. Otherwise they are mostly harmless. At 1 2 to 4 2 months of age the female firebrat begins laying eggs if the temperature is right (3241 C or 90106 F). It may lay up to 195 eggs in a lifetime.
