Here’s how to identify, prevent, and eliminate boxelder bugs effectively in Calgary homes and businesses.
🔍 1. What Are Boxelder Bugs?
Boxelder bugs are black with red or orange markings on their wings and measure about 12–14 mm long. They feed primarily on boxelder, maple, and ash trees, especially the seeds and leaves. When temperatures drop, they gather on sunny walls and windows before sneaking indoors through cracks and gaps to overwinter.
🚪 2. How to Prevent Boxelder Bugs from Entering Your Home
Prevention is the most effective way to control boxelder bugs. Follow these proven steps:
🔸 Seal all entry points: Caulk cracks around doors, windows, vents, and siding.
🔸 Install screens: Add fine mesh screens on attic vents and repair any damaged window screens.
🔸 Inspect foundations: Seal gaps where pipes, wires, or cables enter your home.
🔸 Reduce outdoor attractants: Rake up fallen seeds and leaves near boxelder or maple trees.
🌿 3. Natural Boxelder Bug Control Methods
If you notice boxelder bugs gathering outside your home or on walls:
🧴 Spray with soapy water: Mix dish soap and water to kill bugs on contact.
🧹 Vacuum indoors: Remove bugs instead of crushing them to avoid odor and stains.
🪟 Clean window sills: Remove dead bugs regularly to prevent secondary infestations.
