Silverfish are small insects that are normally shiny gray or silver. They are normally around an inch long, and they’re nocturnal, so you may not see them during the day. When it comes to humans, silverfish don’t normally do much. They don’t bite, and they don’t carry any harmful diseases. However, they might cause slight allergic reactions in some people.

When it comes to your property, however, silverfish can do a lot of damage. They are known to feast on anything from insulation in your walls to cereal boxes. They may even eat your clothing or documents. So you don’t want to deal with silverfish in your home or business.
