Spiders control — prevention & targeted treatment
Spiders are predators that help control other pests. Most are harmless; a few species, like the black widow and brown recluse, merit caution.
Signs to look for
- Webs accumulating in corners, attics, or garages
- Egg sacs in undisturbed areas
- Frequent sightings of wandering species
- A steady food source (other insects) keeping spiders fed
Prevention (starts before the pest does)
- Seal gaps around windows, doors, and vents
- Reduce clutter and cardboard storage where they hide
- Turn off exterior lights or use yellow bulbs that attract fewer insects
- Keep vegetation trimmed away from the home
Safe DIY limits
- Vacuum webs and egg sacs routinely
- Seal entry points and reduce moisture
- Remove obvious hiding spots in garages and basements
Eco-friendly approach
Least-toxic, targeted approach: habitat change, exclusion, and vacuuming first; spot treatments only where a medically significant species is present.

Common questions
Should I be worried about every spider I see?
Very few species are medically significant. Learn to identify black widows and brown recluses, and contact a professional if you're unsure — most spiders are beneficial predators.
How can I keep spiders out of the garage?
Seal the garage door threshold and around vents, reduce clutter and boxes, and reduce the insects that feed them.
