They can also be found under rocks or logs, but they will also hide inside dark spaces in your home, like closets or basements.

Their bites can cause painful reactions like swelling, redness and itching at the bite site. These reactions can last several days or longer depending on individual sensitivity to their venomous bites. You don’t need to treat centipede bites because they don’t carry disease, and their bites shouldn’t be dangerous. However, you should see a doctor immediately if you have an allergic reaction to the centipede’s poison or if it has bitten you more than once.
