Silverfish are wingless and silvery insects belonging to the order Zygentoma. Although these pest bugs will happily live outdoors in the right conditions, they have also become a nuisance in homes across the Americas, Europe, Asia, Africa, Australia, and Pacific islands.
Their name comes from a combination of their color and their smooth, fluid, movements that resemble those of fish.
Silverfish are very common throughout the entire contiguous United States, though visibility tends to drop during the colder months.
Silverfish are not known to be dangerous to humans or pets.
It’s uncommon to have infestations that occur in large numbers, but it’s certainly possible in particular damp, and dark environments.
