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

When spiders are busiest around Roswell
Widows and violin spiders shelter year-round in seldom-disturbed places; NMSU advises never placing a hand where you cannot see or into a tangled web.
NMSU: 'Fortunately, black widows are very shy and very few bites are recorded for the number of spiders occurring in the region,' and 'violin spiders are not especially aggressive and may live in numbers in a house without a bite occurring.' The brown recluse proper (L. reclusa) is reported in eastern New Mexico and established around Roswell; the rest of the state's recluses are native desert species.
