Despite their name, centipedes don’t actually have one hundred legs – some have fewer, though others may have many more. Regardless, the majority of these “creepy crawlies” are very small and completely harmless to humans. They spend their lives under rocks and logs and other moist environments. House centipedes in particular, which many Torontonians might encounter in their basements, cause a lot of fear due to their fast running speed and numerous long legs; however, they may actually be beneficial because they eat smaller invertebrate pests (e.g. silverfish, cockroaches, etc.).
