Boxelder bugs in Quebec
The boxelder bug is a common insect in Quebec. They often gather in large numbers on sunny exterior walls of homes, as well as around doors and windows, especially in the spring and fall.
Although they are not dangerous to humans, their presence can become very invasive, and the insects may occasionally enter buildings.
Boxelder Bug Control
Boxelder bug management is mainly carried out through exterior treatments around the building to reduce their presence near the home and limit their entry indoors.
An intervention performed by a qualified professional helps ensure an effective and safe treatment.

Annual Cycle
In Quebec, boxelder bugs generally produce one generation per year. Adults overwinter in buildings or in natural shelters. In the spring, they emerge to feed and reproduce near boxelder trees, beginning their life cycle again.
The Life Cycle of the Boxelder Bug
Eggs
The eggs of the boxelder bug are small, oval-shaped, and reddish-brown to rust in color. They are laid in clusters in the spring, mainly in the crevices of boxelder tree bark or under leaves. They typically hatch after 10 to 14 days, giving rise to bright red nymphs.
Nymph (Juvenile Stage)
The boxelder bug nymph is bright red with black markings. At this stage, the insect does not yet have fully developed wings and measures only a few millimeters in length. Nymphs often gather in large numbers on the trunks of boxelder trees, on fallen seeds on the ground, or on warm, sunny surfaces near buildings. During their development, nymphs go through several molts before becoming adults. During this period, they feed mainly on the seeds, leaves, and sap of boxelder trees.
Adult
Adult boxelder bugs measure about 12 to 14 mm. Their bodies are black with red or orange lines on the wings, forming a characteristic X-shaped pattern.
In late summer and especially in the fall, they gather on the sunny walls of homes and buildings in search of a place to overwinter. At this time, they may enter houses through cracks, windows, or soffits.
