Signs of spiders in San Diego County
Spider activity is easiest to confirm by looking in the undisturbed corners of a garage, shed, or exterior eave. Web style and location both help identify what you are dealing with.
How to tell if you have spiders
- Irregular tangled webs in cornersBlack widows and common house spiders build messy, non-symmetrical webs low in garages, sheds, and under eaves.
- Egg sacs attached to websRound, tan or off-white sacs about the size of a pea mean a female spider is actively reproducing nearby.
- Spiders in stored itemsFinding spiders in boxes, shoes, or gloves that have sat undisturbed points to an active nesting spot.
- Web buildup near outdoor lightsPorch and garage lights attract flying insects, which in turn draws web-building spiders to the same fixtures.
- Shiny black spiders with red markingsA black widow sighting, especially near ground level in a garage or woodpile, should be treated as a real signal, not a one-off.
What to do next
Keep garages and sheds decluttered, trim vegetation back from the house, and treat outdoor lighting with insect-reducing bulbs to cut down on the food source spiders are chasing.

Common questions
Are black widows common in San Diego County garages?
Yes. Black widows are one of the most common spider calls across San Diego County, especially in garages with stored boxes and wood.
Does killing spiders on sight actually help?
It removes one spider but not the egg sac or the food source drawing them in. Clearing webs and reducing insects works better long term.
What should I do if I find a black widow egg sac?
Avoid handling it directly. Knock it down carefully with a broom or call a pro if you are finding multiple sacs in the same area.
