Q.House Plants That Deter Asian Beetles
We have Asian beetles in our log home. Are there any houseplants that will repel them?

No. They are attracted to the vertical lines of our homes and buildings. Some say to plant mums outside near possible entry points but I didn't see that validated anywhere. They come inside to overwinter. Experts don't recommend insecticides because they work too slowly. Also, Asian beetles are considered beneficial insects because they eat aphids in the garden. The best thing to do is vacuum them up. Try to prevent them from coming in by sealing up the cracks around doors and windows.
