How do I get rid of boxelder bugs?
What You Can Do
To stop boxelder bugs from multiplying, it is often helpful to remove their host trees from the area surrounding your home, but the adults can still fly to locations off of the property.
If you choose to plant boxelder trees in your yard, choose male trees (non-seed-bearing) since female trees are more susceptible to infestation. These trees are not recommended for ornamental planting.

Adult boxelder bugs live and breed on leaves of boxelder trees.
These bugs prefer to lay their eggs in these trees during spring. Their eggs are reddish brown in color, allowing them to stay well hidden in the bark of the host tree.
After a few days, the eggs hatch into red and gray nymphs, which eventually mature and begin the breeding process again.
Mature boxelder bugs can be found gathering in large numbers on branches and boughs. Concentrations will be heaviest in areas receiving sufficient sunlight.
