Garden Spider

Garden spiders are not dangerous to humans or pets. They are docile and bite only if grabbed or trapped against the skin, and on the rare occasion that happens, the result is typically mild and short-lived, similar to a minor bee sting with some local redness or swelling. They carry no medically significant venom for people. If you simply leave them on their web and avoid handling them, there is no real risk, which is why we generally recommend leaving them undisturbed.

Garden spiders are large, with females reaching up to about an inch, and show a striking bright yellow-and-black pattern on the abdomen. The clearest tell is the white zigzag band, called a stabilimentum, woven down the center of a large circular web, where the spider hangs head-down. Dangerous Southern California spiders look very different: black widows are glossy black with a red hourglass and build messy webs, and the reclusive desert recluse is uniformly tan with a violin mark and avoids open webs entirely.

Because garden spiders build in sunny, sheltered spots near a steady insect supply, the simplest deterrents are clearing webs from entryways and seating areas with a broom, trimming back overgrown weeds and flowers next to those zones, and reducing nighttime lighting that draws the insects they hunt. They will usually rebuild out in the garden where they belong. If webs keep reappearing in high-traffic areas, a licensed technician can relocate the spiders and apply precision-targeted treatment, often as part of recurring service.
