The answer to 'why is my silverfish bites' is that silverfish do not actually bite humans. Silverfish are small, wingless insects that feed on things like paper, starch, and sugar. While they can sometimes crawl on people, they do not have the ability to bite or sting. Any perceived bites or irritation is likely caused by something else, such as dry skin, allergic reactions, or other pests.
Silverfish are generally harmless to humans, but they can be a nuisance and cause damage to household items. If you're seeing signs of silverfish in your home, it's best to take steps to eliminate their food sources and remove any damp, humid conditions that they prefer. This may involve sealing cracks and crevices, reducing moisture, and using traps or baits to control the population. If the problem persists, it's a good idea to call in a professional pest control expert to properly identify and treat the issue.
