Local spiders conditions in Cody.
Cody sits in a semi-arid continental climate, and that sets the pace for spider activity here: late summer through fall (August-October).

What a spider visit looks like.
Inside, they focus on corners, closets and the garage. They treat cracks, gaps and hiding spots, not open lawn. They knock down webs and egg sacs around eaves and windows. The tech walks the outside first. Most visits take about an hour.
Sticky traps tell you a lot.
They show which spiders you have and where they travel. Check them after a week. Set sticky traps along baseboards, behind furniture and in the garage.
Outdoor lights and spiders.
Motion-sensor lights help too. Yellow bulbs attract fewer bugs. Porch lights draw insects, and insects draw spiders.
Cellar spiders in the basement.
A dehumidifier and a broom keep them in check. They're harmless and even eat other spiders. Long-legged cellar spiders hang in basement corners.
Spiders in the garage.
A door sweep and a sticky trap by the door help. Store things in sealed bins off the floor. Garages collect webs, boxes and insects.

When spiders are busiest around Cody
Black widows are spotted sunning in webs on cool summer mornings; spiderlings disperse into buildings and are too small to exclude by sealing alone (UW Extension).
University of Wyoming Extension entomologist Scott Schell: brown recluses 'are apparently an outdoor spider that spills indoors in their native range, the southcentral U.S.' Wyoming's real medically significant spider is the western black widow, and 'black widows bite very few people despite being common in Wyoming.'
