Silverfish Infestation

These insects are nocturnal creatures and will hide for most parts of the day. Once nighttime comes, they go out to wander around and feed. Silverfish and firebrats all like dry foods including oatmeal, book bindings, any paper with glue on it, pet food, and flour. What’s more, they like munching on cotton, silk, and linen, but they also eat protein-rich foods such as dead insects, fungi, and dried meats. These insects are also cannibalistic. They’ll make a hearty meal out of injured or dead members of their kind.

A male silverfish will attract a female with a mating dance that involves antennae touching and some head bobbing. Afterwards, the male will then leave the female a sperm capsule. A female silverfish will lay its eggs in an area that’s protected. It may also burry its eggs in your food or in household dust. A female lays up to 50 eggs. Adults will live up to 3 years.

Silverfish and Firebrats in a Home or Apartment

As for firebrats, they prefer environments that are dry and warm. They hide and breed around ovens, hot water pipes, and heating units. Both insects will invade homes during the summer season as conditions outside start becoming dry. Firebrats and silverfish also hitchhike into your home on lumber and drywall. These pests ruin books, documents, and clothing pieces with their habit of feeding.
