Silverfish appear frequently in homes, but the temperature they enjoy depends on the type of silverfish insect in particular. All versions and varieties can cause damage — typically to paper products and wood. However, the environments they prefer vary.
Understanding how each breed grows in its ideal set of conditions can help with eradication.
Firebrats
The firebrat is a high-temperature variety of the silverfish. This type of insect prefers areas with significant heat — as much as 90 degrees Fahrenheit or warmer. Preferring to function and live near sources of strong ambient heat (not burning), firebrats can appear near heaters and related piping and ovens, as well as the surrounding furniture or nooks adjacent to a well-used fireplace. Even hot-water pipes will trigger notice for the bugs if the plumbing runs frequently. Locale-wise, firebrats are common in the lower, warmer states such as Arizona. While they do avoid light, they migrate toward heat emanation in the dark.
Four-Lined Silverfish
This type of silverfish functions in both temperature modes. Formally known as the Ctenolepisma lineata, this variety of silverfish has a hardier body and longer legs. In terms of temperature, the four-lined silverfish can be found in either cold or hot climate. While the insect will migrate toward warmth given the option, it’s not the type of insect that simply dies in cold winter.
