Battling Boxelder Bugs!
Boxelder bugs are one of the most common and widely distributed household pests in the Chicagoland area. These distinct red and black bugs are a nuisance to homeowners because they often gather in large numbers on the sides of buildings and on nearby ornamental plants and trees.
They enter homes through:
- open doors
- open windows
- through cracks around sills
- bellow siding
BIOLOGY: The favorite host for this insect is the Boxelder tree (Acer negundo) especially the female tree, which bears the seed pods. Boxelder bugs may also feed on trees in the maple family. Since these insects can migrate great distances, it is not practical to remove the trees in order to reduce their population for Boxelder bug control.
During spring Boxelder bugs can be seen emerging from hibernation sites. Females begin to lay eggs during April and May, depositing them around host trees. The development from egg to adult takes about 60 days.
In the fall, there is an increase in the number of insects on homes and structures as the Boxelder bugs look for suitable sites to overwinter. This is the ideal time to perform Boxelder bug control with exterior barrier treatments. By treating homes in late September and October the Boxelder bugs are prevented from overwintering.
Boxelder bugs overwinter in such places as:
- wall voids
- crawl spaces
Although it is difficult to achieve 100% elimination of this pest, Boxelder bug control applications by Chem-Wise during October will drastically reduce the population and decrease sightings throughout the year. Contact your local office for more information or click here.
