Most spiders homeowners run into across Phoenix, Scottsdale, Mesa, Tempe, Gilbert, Chandler, Queen Creek, San Tan Valley, Apache Junction, and Cave Creek are harmless, even helpful, since they’re eating other bugs around the home. The one that actually matters is the black widow, which is common in garages, sheds, and woodpiles throughout the Valley and does require real caution.

What kind of spiders are in the Phoenix area?

Black widows are the spider to actually pay attention to here. They’re shiny black with a red hourglass marking on the underside of the abdomen, and they build messy, irregular webs low to the ground, often in garages, under eaves, in woodpiles, or tucked into patio furniture that doesn’t get moved often.

Wolf spiders are the other one people usually notice, mostly because of their size. They’re large, brown, and fast moving, which makes them look far scarier than they actually are. They don’t build webs and aren’t dangerous, they just hunt on the ground and occasionally wander inside.

You may also see jumping spiders, which are small and harmless, and desert recluse spiders on occasion, a relative of the brown recluse found in parts of Arizona, though bites are uncommon and usually far less severe than their eastern relative.

Signs you have a spider problem

• Webs low to the ground in garages, sheds, or under patio furniture, especially messy, uneven webs rather than the neat circular kind
• Egg sacs, which look like small tan or off white silk pouches, often tucked in a corner near a web
• An increase in spider sightings after moving stored boxes, firewood, or furniture that hasn’t been disturbed in a while
• Large spiders indoors at night, which is typically a wolf spider passing through rather than a nest inside the home

A spider or two around the outside of the house is normal in this climate. Regular black widow sightings in the garage or a cluster of egg sacs is the point where it’s worth addressing directly.

Are spider bites actually dangerous?

Most spiders in this region aren’t a real threat. The black widow is the exception. Its bite can cause muscle pain, cramping, and nausea that spreads from the bite site, and while it’s rarely life threatening for a healthy adult, it can be more serious for young children, older adults, and anyone with a health condition. If a black widow bite is suspected, especially in a child, it’s worth calling poison control or seeking medical care rather than waiting it out.

Why do I keep finding spiders around my house?

Spiders show up wherever there’s food and an undisturbed place to build a web. Outdoor lighting draws in flying insects at night, and spiders set up nearby to take advantage of it. Garages, woodpiles, and storage areas are ideal for black widows specifically, since they’re dark, quiet, and rarely disturbed. If a home has an active population of crickets, roaches, or other small insects, spiders are simply following the food source.

How Trellis handles spiders

Spider control fits naturally into our Triple Lock Protection System, since knocking down webs alone doesn’t stop the problem, spiders will just rebuild if the conditions that drew them in are still there. We treat the yard and eliminate the insects spiders are feeding on, create a barrier along the fenceline, and treat the perimeter of the home, including eaves, garages, and other common web spots, so both the spiders and their food source are addressed together.

Spider control is included in every general pest membership at no extra charge, and it’s part of the regular bi-monthly service alongside ants, scorpions, and other common Valley pests.

How much does spider control cost?

Spider control is included in our general pest service, no separate specialty charge. Pricing is based on home size, the same as the rest of general pest coverage, and it’s covered under the same bi-monthly visits as everything else.

Can I get rid of spiders myself?

Knocking down webs and vacuuming up egg sacs helps in the moment, but it doesn’t stop new spiders from moving in if there’s still food and shelter drawing them to the property. For black widows specifically, it’s worth being cautious rather than reaching directly into a woodpile or storage box by hand, since bites usually happen when a spider feels cornered or gets pressed against skin without warning.
