Unlike other insects, silverfish are wingless. Their body is a tapered carrot shape, covered with silvery scales. They have three slender bristles behind their back.
Silverfish are mostly found in moist areas, like bathrooms, sinks, and basements. They love to hide under objects. As a result, they can be hard to find.
These little insects are one of the oldest species on Earth. Some scientists believe they have cousins who have lived for more than 400 million years.
Silverfish are nocturnal, meaning they only come out at night. In addition, they prefer dark places.
They’re small and slender, with metallic brown or bluish-silver scales. Their antennae are long and curved. The females have an ovipositor, which picks up the spermatophores laid by the male.
Females lay a cluster of 2 to 20 eggs, and some species lay only a few per day. The eggs are about 0.04 inches (0.1 cm) in length.
Adult silverfish are usually a half-inch to three-quarters of an inch long. Unlike other insects, they are not venomous. Although they can be aggressive, they do not transmit diseases.
They are nocturnal, which makes them easier to see at night. You can spot them in dark places, like under furniture, or in damp basements.
Silverfish are a nuisance. They can destroy items you don’t notice. This can negatively affect your home’s quality of life. And their infestations can become worse as they reproduce. Fortunately, you can prevent an infestation.
