Centipede Infestations In The Attic

Next on our list of common attic pests are the creepy, crawly — and oftentimes dangerous — centipedes. Not to be confused with the harmless millipede, centipedes are fast, venomous insects that are capable of growing over hundreds of legs. Although their bites are rarely fatal (only some of the larger tropical species pose a serious threat), they still have a painful bite that may become infected if not properly cared for. This is why it’s important for homeowners to treat centipede infestations at the first sign of a problem.

Fact: Centipedes Are Attracted To Water

If centipedes are a problem in your attic, there’s a good chance that water is leaking or building up somewhere in it. Most homeowners notice centipedes in the kitchen or bathroom, as these areas typically contain water. However, centipedes will travel to any part of the home where water is present, including the attic.

The first step towards treating a centipede infestation in the attic is to remove standing water. Centipedes, like most insects, are naturally attracted to water. By removing water sources in your home, you’ll encourage them to stay outside rather than taking refuge in your attic.

Common Sources of Water In The Attic

  • HVAC condensation pan overflowing
  • Excessive humidity
  • Leaking roof
  • Poor ventilation

Note: if your attic experiences a high level of humidity, consider using a dehumidifier to help draw the moisture out of the air. Certain regions are prone to higher levels of humidity, and even proper ventilation does little to control it.

Should I Hire a Professional Pest Control Company?

Whether or not to hire a professional pest control company is a decision that you’ll have to make. Centipedes infestations are relatively easy to control if you’re willing to put forth the effort. After removing sources of moisture and water from your home, go around the exterior of your home to remove piles of debris and mulch. Also, keep your lawn manicured so there’s room for centipedes and other bugs to hide.

Depending on the severity of the infestation, you may want to spray your attic with an insecticide chemical. You can find some professional-grade chemicals available for sale at most DIY pest supply stores, one of which is Demon WP. This water-soluble insecticide is highly effective for treating centipedes, scorpions, roaches, ants and dozens of other insects.
