Spider Control

Spiders in Southern California

In sunny Southern California, spiders thrive around homes year-round. Common indoor species include the web-spinning American house spider, the long-legged cellar spider, and the swift wolf spider. Outdoors, brown and black widows are often found near patio furniture during warmer months, while orb-weavers dominate late summer and fall, weaving webs in shrubs, trees, and roof eaves.

Mind the Gaps

Spiders enter homes through tiny cracks, gaps in foundations, pipe openings, or poorly sealed windows and doors. They can also hitch a ride with firewood, potted plants, or packages left on your doorstep. Janus Pest Management will inspect your property and recommend tailored solutions to seal these entry points, keeping spiders out.

Comprehensive Spider Control

Thanks to our Mediterranean climate, spider populations surge early in April through November, peaking in late summer. Black widows are especially persistent—one female can produce 3 to 10 egg sacs, each containing 100 to 400 eggs. Spiderlings disperse through ballooning, rapidly spreading infestations.

At Janus Pest Management, we take a proactive approach to control. Our services include removing egg sacs, clearing webs from eaves, porches, and patio furniture, and applying multi-mode action (MOA) treatments to prevent infestations before they start.
