Dealing With Spiders in Cotati Homes
Most of the spiders found in Cotati homes are not dangerous, but a few species deserve care, mainly the brown recluse and the black widow where they occur. Identification comes first, because webs, egg sacs and hiding spots differ by species. Pest control technicians check basements, closets, sheds and the corners of ceilings, where spiders settle near their prey. Spiders keep coming when crickets, flies and other bugs are around, so the plan often includes their food supply too. A follow-up visit looks for new webs and egg sacs. Bites are uncommon, yet if someone may have been bitten by a recluse or widow, call a doctor or poison control, or 911 for serious symptoms.

Before the Exterminator Arrives
- Do not handle the spider. If you think it is a brown recluse or black widow, keep your bare hands off it. Cover it with a jar and slide a card underneath, or save the specimen so the technician can identify it.
- Wear gloves around clutter. Black widows and recluses hide in boxes, woodpiles, garages and shoes. Wear gloves when you move stored items, and shake out shoes and clothing left on the floor.
- Know when a bite needs help. Call poison control, a doctor or 911 right away if you think a brown recluse or black widow bit someone, or if symptoms are serious. Keep the spider if you can do so safely, since it helps with identification.
- Cut off food and hiding spots. Vacuum webs and egg sacs and empty the vacuum outside. Move clutter off the floor and away from walls, seal boxes, and cut back shrubs and ivy that touch the house.

Signs You Need Pest Control For Spiders
- Violin-marked brown spiders in closets and boxes. Brown recluses are plain tan to brown, with a darker violin shape on the head and six eyes in pairs. In areas where they live, they hide in dry, undisturbed spots such as boxes, closets and behind furniture.
- Black widows in woodpiles and garages. Females are shiny black with a red hourglass on the underside. Messy, tangled webs close to the ground in sheds, meter boxes, woodpiles and garages are typical.
- Fast, hairy spiders on floors at night. Wolf spiders hunt rather than build webs, and they turn up in garages, basements and near doors. They look alarming but are not usually dangerous, though they can bite if handled.
- Funnel-shaped webs in low spots. Hobo spiders and grass spiders make flat webs with a funnel at the back, in window wells, foundation cracks, basements and under rocks. The spider waits inside the funnel.
- Cobwebs and round egg sacs in corners. House spiders leave tangled webs in ceiling corners, eaves and window frames, often with papery egg sacs hanging in them. Lots of webs usually mean lots of insects to feed on.
Local conditions
Pest Control For Spiders in Cotati: What to Know
In California, black widows are common in woodpiles, garages and yards, and false widows, wolf spiders and house spiders turn up indoors. Brown recluses are not native to California. Black widows and house spiders are the usual ones indoors in California.
Calls about spider problems come from every Cotati ZIP code, day and night.
How the Job Is Done
- Identify and inspect. The technician checks corners, eaves, basements, garages, window wells and storage areas, and identifies the species. A brown recluse or black widow needs different attention than a common house spider.
- Treat hiding spots and entry points. Product goes along baseboards, cracks, eaves and window frames, and a dust may be used in wall voids. Webs and egg sacs are brushed or vacuumed away.
- Reduce their food and follow up. Spiders follow their prey, so the plan also covers crickets, flies and other insects. A return visit checks for new webs, and a regular plan can keep numbers down.
