Firebrats lay about 50 eggs at a time in batches. The eggs hatch in about two weeks under warm conditions. Young silverfish and firebrats look like the adults except for being smaller and white. Depending on the species, silverfish and firebrats typically reach maturity in three to 24 months. In general, silverfish prefer damp, cool areas and can be found throughout the home.
Firebrats prefer hot places such as near ovens, fireplaces, furnaces and hot water pipes.
Silverfish and firebrats are typically brought into a home in food, books, paper, starched clothing and furniture. Their populations tend to increase slowly. If a large infestation is present in a house, it is usually an indication of longtime infestation. The first step to control is identification of the particular species that you have. Identification is helpful in determining the preferred living areas and food materials, which helps in locating the infestation.
