Do you find yourself feeling disgusted and driven to get rid of any insects you find in your house? It makes perfect sense, particularly because some of them are very harmful and contain toxins that can cause stings that are excruciating or even lethal.

However, think about this before you squash that house centipede you discovered in your bathroom—they might be helping you out after all. Despite their unsettling appearance, centipedes are essential for preventing other little pests from entering your home.

They are known to eat every arthropod they come across because they have such a voracious appetite. So why not be grateful and leave them alone instead of crushing them?
Now, I’m not saying that you should bring swarms of centipedes inside your house. However, it seems reasonable to spare the odd one or two you find as a sign of appreciation. Simply let them to go or gently take them outside so they can eat some leaves.
Another reason to reconsider your decision to smash every bug you come across is the possibility that doing so could unintentionally unleash hundreds of young spiders into your house. You don’t want to watch it, I assure you.

In all honesty, centipedes aren’t all that horrible. They’re basically harmless little creatures that can’t really hurt you, other than frightening you. Additionally, they don’t contaminate your house with pathogens like other insects do. They are the good people because of this!
