Interesting Facts

They will congregate on the south and west sides of buildings to seek heat.


They congregate on the south and west sunny sides of the home. They make their home in a box elder, maple or ash tree during warmer months and migrate into buildings and homes to find shelter in the winter.

Boxelder bugs enter buildings through small cracks and crevices and will emerge when heat sources are high in the building. They do not cause damage to buildings, however, they leave droppings and stains on furniture and linens.

How does Batzner get rid of boxelder bugs?

Your Batzner Service Professional will come to your property to identify the source of the boxelder bugs and determine the proper treatment method. Fall is the time to help prevent Boxelder Bugs from using your building or home as a refuge for the coming winter season. With the onset of cooler temperatures in autumn, these insects congregate on buildings in search of overwintering sites. To prevent pest entry, treatment must be applied before the insects begin to enter buildings during late September or early October to be effective. Once the pests have entered the building, treatments can be done in Winter or Spring. The most effective pest management option is prevention. Prevention is the key!

What steps can I take to control or prevent boxelder bugs myself?

Prevent boxelder bugs from entering your home or business in the first place by sealing off all entry points to the building outdoors. This includes areas where phone lines, cable TV wires, and other pipes and vents enter buildings. Repair or replace any damaged window or door screens, screens in roof vents and in bathroom and kitchen fans.
