Common House Spider in Commercial Drive.

Why common house spider activity is specific to Commercial Drive

Commercial Drive's spider profile is similar to Mount Pleasant's but with slightly different housing mix: more three-storey walk-up apartments, more restaurant and retail ground-floor stock. House spiders here establish in basement restaurants (drawn by insect prey), apartment unit windows, and residential crawlspaces. Hobo spiders (Eratigena agrestis) show up occasionally; the rest are benign common house spiders that help control other indoor insects. Our Commercial Drive spider work is nearly always ID-first — we usually don't treat beneficial spiders, and we work with residents on realistic tolerance thresholds for spiders that aren't a medical concern.
