Centipedes are one of the ugliest creepy crawlers found indoors, with their squishy bodies and long legs, and when you see one on your basement ceiling you probably have the urge to kill that sucker. But you might want to consider setting that centipede free instead because it could actually come in handy.
Why You Should Not Kill a Centipede

Centipedes eat other uglier creepy crawlers such as ants, spiders, bed bugs, cockroaches, and silverfish; in fact, they’ll eat any arthropod pests. They are not poisonous or dangerous so you are not putting yourself at any risk in keeping them around. That being said, you don’t have to have dozens of them crawling around in your house, they are creepy and not fun to look at. Instead, scoop it up in a jar and release it outside, preferably somewhere damp.
