There are several ways to kill centipedes, depending on the severity of the infestation and personal preference. Here are some methods:

1. Insecticides: Synthetic pesticides containing pyrethoids, bifenthrin, or cypermethrin will kill centipedes on contact. Ortho® Home Defense Max® Indoor Insect Barrier with Extended Reach Comfort Wand® and Ortho® Home Defense® Insect Killer for Cracks & Crevices are two products that can be used to kill centipedes. However, chemical insecticides should be used sparingly to maintain the quality of air in your home and keep children and pets away from treated areas.

2. Natural dusts: Natural dusts like boric acid and food grade diatomaceous earth can kill centipedes and work well for continual centipede control. These options are non-toxic and can be sprinkled at points of entry, such as baseboards, cracks, crevices, doors, and windows.

3. Sticky traps: Sticky traps made for general insect use can be placed near baseboards or in corners to catch centipedes when they walk on them.

4. Vacuuming: Centipedes can be vacuumed up when they are found, and the vacuum bag should be sealed and disposed of to prevent them from escaping.

Its important to note that centipedes are beneficial predators that eat other pests, so consider removing them from your home instead of killing them if possible. To prevent future centipede problems, eliminate their hiding places by thoroughly cleaning damp areas of your house, like the basement, bathroom, or attic, and reducing moisture. Additionally, getting rid of other pests in your home can eliminate the centipedes food source.
