Silverfish

The Marvelous in Nature:

An individual silverfish can live as long as two to eight years. Think about that. If you moved in the last few years, there might be silverfish in your house that have lived there longer than you have. Fortunately, they’re not that prolific; a female may lay fewer than 100 eggs in her lifetime. And a healthy household population of earwigs, spiders and house centipedes will also help keep their numbers down.
