Sacramento sits in a mediterranean climate, and that sets the pace for spider activity here: late summer through fall (August-October).

An inspection in Sacramento usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first.
The gap under a door is one of the easiest ways in, for spiders and for the insects they follow.When you’ll see more of them.
Spring brings a new hatch. Clear egg sacs in winter. You'll see the most in late summer and fall. That's when males wander. Winter lows around 39°F in Sacramento slow spiders outside, but house spiders carry on indoors.

- Doorways and porch lights: brush webs away weekly. - Eaves and window frames: a long-handled brush works well. - Woodpiles: keep them off the ground and away from the house. - Gloves: wear them when moving firewood, pots or patio cushions. - Garden orb weavers: leave them.

Spiders and pets.
Most spiders are no threat to pets. A widow bite can sicken a dog or cat. your vet. Some sprays are risky for cats. Ask the company which products are cat-safe.
What a spider visit looks like.
Most visits take about an hour. The tech walks the outside first. They knock down webs and egg sacs around eaves and windows. They treat cracks, gaps and hiding spots, not open lawn. Inside, they focus on corners, closets and the garage.
Sticky traps tell you a lot.
They show which spiders you have and where they travel. Set sticky traps along baseboards, behind furniture and in the garage. Check them after a week.
Outdoor lights and spiders.
Motion-sensor lights help too. Porch lights draw insects, and insects draw spiders. Yellow bulbs attract fewer bugs.
Cellar spiders in the basement.
A dehumidifier and a broom keep them in check. Long-legged cellar spiders hang in basement corners. They're harmless and even eat other spiders.
Spiders in the garage.
A door sweep and a sticky trap by the door help. Garages collect webs, boxes and insects. Store things in sealed bins off the floor.

- Clear webbing from eaves and deck framing every few weeks during the dry season rather than once a year.
- Move woodpiles off the ground and away from the wall, since Sacramento woodpiles are prime widow habitat.
- Check irrigation valve boxes and the water meter lid, which stay damp and dark all summer.
- Replace white exterior bulbs with warm or amber ones to cut insect traffic at the door.
- Store garage contents in sealed bins on shelves instead of stacked cardboard on concrete.
- Fit door sweeps and repair screens before the first cool nights in September.
- Shake out gardening gloves, boots, and cushions that have sat unused through the dry months.
