BOXELDER BUG

HOW TO GET RID OF BOXELDER BUGS

Boxelder bugs (also spelled 'box elder bugs') are well known insects here in Ontario, appearing in homes in the fall. Boxelder bugs stray into houses through cracks in the foundation and siding, gaps along windows and doors, and other small openings.

The boxelder bug is usually between 11mm and 14mm (or 1/2") in length, and has a dark body with red markings on it. They winter over inside buildings, entering in the fall and leaving again in the spring. They are not truly harmful insects, though they do pose a nuisance.
