Kill an infestation of Asian beetles using a combination of methods including vacuuming them up, drowning them in liquid soap, placing glue traps and spraying insecticide indoors and outdoors. Beware of traps that attract beetles using pheromones, as they may attract more beetles than they catch.Continue Reading
Use the hose attachment to vacuum beetles from light fixtures, windows and other areas where they congregate. Secure a nylon stocking inside the hose with a rubber band so the beetles are bagged within the stocking and can be easily removed and disposed of.
Use light to lure beetles to traps. However, the light does not kill the beetles, so drown them in liquid soap afterwards.
Place glue traps on window sills and near light fixtures. The beetles get stuck on the traps and die. Replace the traps as needed.
Spray a pyrethrum-based fog in indoor areas where other extermination methods have not been effective. Clear the room as much as possible, close all windows and doors, fog the room, and stay outside as long as the directions on the sprayer indicate.
Check the soil under your lawn in late summer if you are experiencing repeat infestations. If you find an abundance of beetle grubs, treat the lawn with an insecticide that kills grubs.
