These little insects have a unnerving presence and are reputed to cause nasty bites which makes them seem threatening. Before we figure out how to eliminate them we should try to answer why they are there in the first part. Similar to silverfish, the moisture content in the house attractions them into the house, so investing in a dehumidifier maybe your first step. Also keep in mind that baths and showers create a lot of moisture, so make sure to run your bathroom fan often. On the outside of the house, anything that absorbs water such as mulch, attracts house centipedes. Keeping mulch, soil and debris away from the foundation of the house helps. Cracks and crevices in foundation, doors and windows are entry points for these pests, and should be sealed. Their diet includes: spiders, beetles, cockroaches, moths, and a lot more, so the fact that centipedes are in your house could also mean you have other insect issues in your home.
