Firebrats are close relatives of silverfish, sharing a similar body shape but preferring warmer environments. Commonly found near ovens, boilers, and heating systems, they are a frequent nuisance in commercial kitchens, bakeries, and industrial facilities across Kenya where consistent heat sources are present.
Common Types of Firebrats
Common Firebrat (Thermobia domestica)
The primary species encountered indoors, mottled grey-brown in color, thriving in temperatures between 32°C and 41°C — making kitchens, boiler rooms, and areas near industrial ovens ideal habitats.
What Attracts Firebrats
1. Heat sources — Ovens, water heaters, furnaces, and boiler rooms provide the warm microclimate firebrats require to thrive and reproduce.
2. Starchy and organic debris — Crumbs, flour dust, cardboard, and paper products near kitchens and storage areas serve as a steady food source.
3. Moisture near heat — Areas combining warmth with residual humidity, such as around dishwashers or laundry equipment, are particularly attractive.
4. Cracks near heat-generating equipment — Gaps behind ovens, boiler housings, and heating ducts offer shelter close to a stable food and heat supply.
How to Keep Firebrats Away
Clean food debris and flour dust from kitchen equipment and floors regularly, especially around ovens and stoves. Seal cracks and gaps behind heat-generating appliances where firebrats hide during the day. Store dry goods in airtight containers rather than paper or cardboard packaging, and address any moisture issues near boiler or laundry rooms promptly.
Why Professional Treatment Matters
Because firebrats favor hard-to-reach areas around industrial equipment, commercial kitchens and bakeries often need professional-grade treatments that safely target these zones without disrupting food-safety compliance. Pest control technicians apply appropriate residual insecticides or dust formulations into wall voids and equipment gaps, tailored for food-handling environments.
Firebrats are a specialized nuisance tied closely to heat sources in kitchens and industrial spaces. Regular cleaning around ovens and heating equipment, proper food storage, and professional treatment for commercial facilities keep firebrat populations from establishing a foothold.
