Spiders

Black widow, brown recluse, wolf spider, cellar spider

Overview

Most spiders are beneficial predators, but a few species (black widow, brown recluse) are medically significant. Correctly identifying the species is critical before deciding on treatment.

How to Confirm

Distinctive web patterns (funnel webs, irregular webs, or no web)
Red/orange hourglass marking on underside (black widow female)
Violin-shaped marking on cephalothorax (brown recluse)
Egg sacs in sheltered corners or under furniture

DIY vs. Call a Pro

General spider control with sticky traps + residual spray is DIY-friendly. Confirmed black widow or brown recluse activity in living areas may warrant professional treatment, especially with children or pets.
