Firebrats vs Silverfish: What Is the Difference?

Firebrats are close relatives of silverfish and are often confused with them.

The short answer

Silverfish are silvery-grey and prefer cool, damp places, while firebrats are mottled brown and prefer hot, humid places such as near ovens, boilers and heaters. Their habits and damage are similar. Control is similar too: reduce humidity and heat, seal cracks, store items sealed and clean up crumbs.

• Silverfish: silvery, evenly coloured.
• Firebrats: mottled, darker.

Habitat
