How to spot them
Cobwebs collecting in the eaves, garage corners, and around outdoor lights — and in the Central Valley, the one to respect: a shiny black spider with a red hourglass, hanging in a strong, messy web low to the ground in woodpiles, meter boxes, and patio furniture. That's a black widow.
Why they show up in the Central Valley
Our mild winters mean spiders never fully die back, and every outdoor light that attracts insects sets a spider's dinner table. Black widows in particular love the dry, undisturbed clutter of garages, sheds, and fence lines — all standard-issue in Valley homes.
What you can do right now
Knock down webs with a broom, shake out gloves and shoes stored in the garage, and move firewood away from the house. Reducing outdoor lighting (or switching to yellow bug bulbs) removes the insect buffet that draws spiders in.
How Cornerstone handles it
Every regular visit includes sweeping webs and egg sacs from eaves and entry points, plus treatment that thins out the insects spiders hunt. Fewer bugs means fewer spiders — it's the food chain working for you. Black widows around play areas get special attention; tell your technician where the kids play.
