Spider Control in British Columbia
Every September, BC homeowners get the same unwelcome visitor: a palm-sized spider sprinting across the living room floor. That is the giant house spider, now the most common large spider in Metro Vancouver.
BC's mild, damp climate supports spider populations that drier provinces never see. Two optimal treatment windows exist: mid-June before egg-laying begins, and early September as eggs hatch. Two well-timed treatments produce better results than ten panicked spray sessions in October.
