The firebrat is an insect with no wings, almost 13 mm long. Its body is like a teardrop. The head has two long antennae and the abdomen ends in 3 caudal filaments. It resembles silverfish, except that its color is beige, variegated with dark marks and light marks.
The firebrat feeds on paper glue, cotton fabrics, rayon, silk as well as dried beef, flour, pasta, etc.
The firebrat prefers places where it is 32 °C and above with a humidity rate of 70% to 100%. Its favourite hiding places are going to be near heating systems, hot water tanks and any other important source of heat.
The male produces a spermatophore (envelope containing several spermatozoa) which the female introduces into her genital tract. She will then lay 1 to 3 eggs per day which will hatch if the temperature is between 32 °C and 41 °C and with a humidity of 75% to 85%.
