How to Get Rid of Boxelder Bugs
Many people have a problem with the infestation of boxelder bugs in the fall or early spring, which is very common. The pesky insects are approximately 1/2" in length and commonly congregate in large numbers. Other than being a nuisance, they do not pose any type of danger.
How to Get Rid of Boxelder Bugs
Determine where the bugs are entering your home, which is usually through cracks or crevices.
Use caulk, weather stripping or expandable foam to close cracks around windows and doors.
Use a pressure hose to wash the bugs off of exterior walls and trees.
If you have a female boxelder tree the tree would need to be eliminated in order to permanently get rid of the pests. If you want to keep the tree, have it professional sprayed each year before the spring.
Remove any leaves or weeds around the perimeter of the house, particularly on the west and south sides.
If you found a colony of the bugs, spray them with soapy water and it will kill the insects.
