Do Silverfish Carry Disease?
Silverfish are not known to carry any threatening diseases. However, they can trigger allergic reactions, if found in large numbers. Inhaling or accidentally consuming silverfish eggs and their dead body parts can trigger allergy-induced asthma and other respiratory problems. When silverfish feces and dead skin mix with the bodies of other dead pests as dust inside your home, the risk of serious allergic reactions is increased.
And, though not overly dangerous themselves, silverfish attract other, more threatening pests, such as centipedes, spiders, and cockroaches that CAN harm humans or spread diseases.
