I’ve been seeing boxelder beetles inside my house the past two weeks. I’ve sprayed everywhere but they just keep coming. New ones are in my sink and on my counters every morning. Where are they coming from and how do I stop the invasion??
Boxelder beetles are very active in the spring and fall. Typically every fall they find a good spot to hibernate, which is usually a house or some other warm structure, and during the winter they’ll emerge making a nuisance of themselves. To stop them in living areas, you’ll need to treat with some of the D-Force Aerosol we have listed in our Boxelder Beetle Control article.
The real key to stopping the problem will be to get them before they ever get inside. This is usually done by treating the outside in the fall. Failure to get them during this phase almost always insures they’ll be around all winter. In the spring, they’ll be super active as they try to leave the home. Spraying the outside again will be required to help reduce the numbers that successfully leave. That’s because the ones that do get away will come back in the fall so you’ll have to deal with them anyway and getting them as they leave is the easiest time. Remember, most all insect problems originate from the outside so if you follow the treatment details listed in our boxelder beetle article, you’ll be able to keep them out of the home.
