Centipedes are ugly bugs that often find their way into homes. Generally, they are not harmful to humans, but most people would prefer not to share their home with them. Centipedes are rather easy to control, though, if you know how to keep them away.
Centipedes can get to six inches in length. They are more harmless than they look and are, actually, a good bug catcher. They eat spiders, cockroaches and other pests that are often found in homes. They prefer dark and damp areas and are often found in bathrooms. They get in through cracks and other small openings. Centipedes can bite, though. There bite feels like a sting, but it does not usually cause any major problems. They rarely bite humans, but will if they feel threatened or if their food source is gone.
To help control centipedes in your home you should remove their outside habitats like piles of leaves or wood. You can also use diatomaceous earth around your house which is deadly to insects, but a safe for humans and animals. You should also use dehumidifiers in damp areas of your home. Also rid your home of other pests. Without food the centipedes will go elsewhere. Be aware, though, that is a difficult task on its own. You should try the other suggestions before attempting this.
If you have tried all the suggested things and you still have a problem then you may need to contact a professional. Any extreme infestation requires the knowledge and skills of a professional as they understand better exactly how to tackle a pest problem. You may wish to have them treat your home for other pests at the same time to help prevent further infestation of centipedes.
Remember that centipedes rarely harm humans and are more of an annoyance than anything.
