Crawling pest
Spiders Control in Elgin, Illinois
Usually a sign of other insect activity.
What they look like
Common Illinois house spiders are small and brown or gray. Cellar spiders have long thin legs; funnel weavers build sheet webs in ground cover and window wells.
Signs of an infestation
- Webbing in corners, window wells, garages and soffits
- Egg sacs in undisturbed corners
- Regular sightings in basements or around exterior lights
Where they're found
Basements, garages, crawl spaces, window wells, soffits, and around exterior lighting.
Why they show up
Spiders follow their food. Exterior lights that draw flying insects, cluttered storage and moisture-rich basements all create good hunting.
Seasonality in Illinois
Sightings peak in late summer and early fall as spiders mature and males move around looking for mates.
Prevention tips
- Reduce clutter in basements, garages and storage areas
- Knock down webbing regularly so sites aren't re-used
- Switch exterior fixtures to warmer-toned bulbs that attract fewer insects
- Seal gaps around window wells, vents and door frames
When to call a professional
If spider activity is constant, the underlying insect population usually needs attention too. Any concern about a medically significant spider should be handled by a professional rather than guessed at online.
