Quick truth
Silverfish don’t bite or sting. They’re mostly a “humidity + shelter” signal.

Silverfish facts — no need to panic
- They are wingless and shy, so they sprint for cover when the lights flip on.
- They keep molting as adults, which is rare among insects.
- Estimated lifespan: around 2 to 8 years.
- You can live for years with the same silverfish in your home.
- They do not transmit disease.
- A silverfish usually lays fewer than 100 eggs in her lifetime.
- Their diet leans toward starches and glue (paper, book bindings, crumbs), not people.
- They are an ancient lineage of insects that has barely changed in form.
Are silverfish harmful? (No — here's why)
- They eat spare starches and crumbs you did not mean to leave behind.
- They can be low-key enrichment for indoor cats who like to watch tiny skittering creatures.
- They can live as long as the average marriage lasts, which is long-term companionship energy.
- Adorable, in a tiny ancient-dinosaur way.
