Centipedes have venomous claws and very painful bites, both of which can lead to severe swelling or allergic reactions. These issues can lead to very serious health problems for certain people, and even in those with tolerance, the results can last for days.
What about millipedes, you might ask? They’re less dangerous than centipedes but they do still have venom that can lead to allergic reactions. Either way, if it has a lot of legs, you likely want to steer clear.
