The answer to 'how to kill centipede' is to use a targeted insecticide spray or bait. Centipedes are nocturnal predators that feed on other insects, so using a pesticide specifically formulated to kill them is the most effective way to get rid of an infestation. Apply the product as directed, being sure to treat areas where centipedes are commonly found, such as under sinks, in basements, and around the home's foundation.
It's important to follow all safety precautions when using pesticides, including wearing gloves and ensuring proper ventilation. You may need to reapply the treatment every few weeks to keep centipedes at bay. If the infestation persists or you're uncomfortable handling pesticides, it's best to call in a professional pest control technician to assess and treat the problem.
