  1. Identify the species — note if it's a medically significant one (like a black widow or brown recluse) and treat those with extra caution.
  2. Knock down and remove webs on sight, indoors and out; spiders won't stay where they can't rebuild.
  3. Reduce the insects they're feeding on — fewer prey means fewer spiders sticking around.
  4. Apply a residual concentrated insecticide along baseboards, window and door frames, under furniture, and in closets or storage areas.
  5. Treat the exterior foundation (about a foot up the wall and a foot out onto the ground) plus any utility entry points.
  6. Place sticky traps in corners, closets, and under appliances to monitor activity over time.

Wear long pants, a long-sleeved shirt, closed-toe shoes with socks, chemical-resistant gloves, and goggles. Add a respirator if the label calls for it or ventilation is poor.
