Maintaining your outdoor environment can also help keep stink bugs at bay. Regularly trimming trees and shrubs can reduce potential hiding places for these bugs. Moreover, if you use firewood, ensure it’s stored about 20 feet from your home and elevated at least 5 inches off the ground. These measures can make your home less inviting to these unwelcome pests.
Ensure that spaces such as basements, attics, crawl spaces, and garages have proper ventilation to minimize potential hideouts for these bugs. It might be helpful to operate a dehumidifier in these zones and install mesh screens over attic vents and chimneys to keep the bugs out.
