How to identify spiders
- Western black widow: glossy black, red hourglass on underside, messy 3D web
- Brown widow: tan with orange hourglass, ridged tan-and-white egg sacs
- Cellar spiders / daddy long-legs: harmless, long thin legs, indoor ceilings
- House spiders: harmless, small, build small webs in corners
Signs of an infestation
- Messy 3D webs under patio furniture, in garages, around water meters
- Spiky tan egg sacs hanging in protected outdoor spots (brown widow)
- Sudden increase in small insect activity (their prey base)
Why spiders thrive in the SFV
Brown widows have spread aggressively across LA County over the last 15 years and are now common in every SFV city. They favor protected, low-traffic spots: under patio chairs, inside grill covers, behind house numbers, and in block-wall weep holes.

Frequently asked questions
Are black widows really in my yard?
Yes — they're native to Southern California and common in every SFV city. They prefer protected outdoor spots and rarely come indoors. Check under patio furniture, in garage corners, and around water meter boxes before reaching blindly.
What should I do if I'm bitten?
For a confirmed or suspected black widow or brown widow bite, seek medical attention. Bring the spider if you can safely capture it. Most other SFV spider bites are harmless and self-resolve.
How often do you need to treat?
Most homes see lasting relief from a single treatment plus quarterly maintenance. Heavily landscaped properties or homes backing open space often need bi-monthly service in spring and summer.
