You can’t help but to overhear a number of conversations about the masses of beetles congregating on the sides of buildings and making their way into your home. These insects deserve a little more explanation because although they are considered “beneficial” insects during the growing season, they can be serious nuisances now as they aggregate for overwintering.
The USDA first imported these beetles to the United States in the late 70s and early 80s to help with aphid control. They are efficient aphid predators that possess biting/chewing mouthparts that can also deliver an irritating bite to people. If enough beetles congregate inside a home they can also cause a small odor problem, may stain certain substrates when smashed, and occasionally cause an allergic reaction in some individuals.
If there are significant numbers of beetles in your area this fall it probably means that aphids were plentiful in nearby crops and other plants this past summer. These beetles are primarily attracted to the south- and west-facing sides of structures because they radiate/reflect the most heat. Control with a vacuum cleaner, broom and dustpan or have your cat chase them out the door. Insecticides can also be used but consider the cost, use of a chemical and how many insects you are dealing with. You can save money and avoid using insecticides if you have a few beetles in your home.
