  • Soapy water can be used to kill boxelder bugs on the outside of your home, but you should not kill them this way when they get inside. If boxelder bugs escape into your wall voids and die it can attract dermestid beetles. It is best to use a vacuum to get rid of them inside your home. Be sure to dispose of the bag outside.

  • The best solution for boxelder bugs and other overwintering pests is to hire a professional pest control company to apply a spray to your exterior walls. This will keep them out of your home and prevent them from being an eyesore when they come to congregate.
