Eliminate Webs, Reduce Spider Activity, and Keep Them From Coming Back
Spiders follow insects. Where flying and crawling pests gather, spiders build webs and settle into quiet corners, eaves, garages, and crawl spaces. Effective spider control requires more than knocking down webs — it requires treating the places spiders hide, hunt, and lay eggs.
Pestcom Pest Management provides professional spider control services designed to remove existing spiders and create a protective barrier that prevents new infestations.
Why Spiders Appear
Spiders are attracted to:
- Exterior lights that draw insects
- Eaves, soffits, and porch ceilings
- Garages, crawl spaces, and storage areas
- Vegetation touching siding and foundation gaps
When insect populations increase, spiders follow. Seasonal weather changes also push them indoors in search of stable shelter.
Common Problems Spiders Cause
- Webs and egg sacs collecting on eaves, corners, and fixtures
- Startle and comfort concerns for families and pets
- Black widows and other medically important species hiding in undisturbed areas such as woodpiles, sheds, and garage corners
Spiders We Commonly Treat
- Common house and cobweb spiders
- Cellar spiders (daddy-longlegs type)
- Wolf and grass spiders that wander indoors
- Jumping spiders on walls and windows
- Black widows in dark, dry, undisturbed areas
- Funnel-weavers and hobo-type spiders near ground-level gaps
Note on risk: Brown recluse spiders are not established in Idaho. Black widows remain the primary medically important species of concern in this region.
Where Spiders Hide
Indoors
- Garage corners and storage boxes
- Crawl spaces and basements
- Window wells and ceiling corners

Outdoors
- Eaves, soffits, and porch ceilings
- Under decks and patio furniture
- Fence lines, sheds, and woodpiles
- Dense shrubs touching structures
Our Spider Control Process
1) Inspection & Species Awareness
We identify:
- Spider species present
- Web and egg-sac locations
- Insect prey sources
- Entry points and harborage zones
2) Targeted Knockdown & Web Removal
- Web and egg-sac removal on eaves, fixtures, and corners
- Precision applications in seams, voids, and protected areas
- Focused treatments for black widow pressure points
3) Exterior Barrier & Entry Control
- Perimeter treatment around foundations, soffits, and trim
- Entry-gap sealing and weather-stripping guidance
- Vegetation and clutter reduction recommendations
4) Follow-Up & Maintenance
Quarterly service maintains the barrier, removes new webs, and prevents seasonal rebound.
Before & After Your Service
Before we arrive
- Unlock gates
- Move patio items 2–3 feet from walls
- Turn off misters or sprinklers
- Note bite concerns or high-traffic areas
After treatment
- Avoid washing treated areas for 24 hours
- Leave removed webs down
- Expect fewer new webs within 7–10 days
- Switch exterior bulbs to warmer tones to reduce insect attraction
DIY vs Professional Spider Control
Removing visible webs helps temporarily, but without treating harborage areas and the insects spiders feed on, new spiders return quickly. Professional spider control targets the entire environment, not just what you can see.
Prevention Checklist
- Use warmer outdoor bulbs to reduce insect attraction
- Trim shrubs and trees away from siding and rooflines
- Seal door sweeps, screens, and utility gaps
- Store items in sealed bins off the floor
- Keep basements and crawl spaces dry and ventilated

Spiders In Our Area
Spiders are one of the most common pests in the Treasure Valley and are commonly found in residential and commercial properties. These pests are attracted to dark, secluded areas in homes like attics, basements, crawl spaces, and closets.
There are many different types of spiders in the area, but the most common include:
- Black widow spiders: The black widows are one of the most venomous spiders in America. They weave strong, loose webs and use their combed feet to easily tear prey apart. They usually make their web in dark areas and are often found in garages, sheds, woodpiles, and basements.
- Hobo spiders: Hobo spiders are common in the state of Idaho. They’re usually ¼-inch and ½-in-sized arachnids that lurk around on ground level. They make funnel-shaped webs to capture prey such as other insects or even small bugs.
If you think you may have a spider problem in your home or business, call us today for a free inspection. We will find the source of your infestation and create a customized treatment plan to get rid of these pests for good!
What Is the Lifespan of a Spider?
Most household spiders live 1–3 years, though some species may live longer under ideal conditions. Females typically live longer than males. Because spiders reproduce and lay egg sacs inside protected areas, populations can grow quickly if not controlled.

-
Do you monitor after it’s resolved?Yes - monitoring and rechecks can be added, especially for canal-adjacent lots, open-field edges, or foothill neighborhoods.

Are Spiders Dangerous to Humans?
Most spiders are harmless and avoid people. However, a small number of species, especially black widows, can cause medically significant bites. While bites are rarely fatal, they can be painful and require medical attention.
Professional spider control reduces the risk by removing both spiders and the conditions that allow them to thrive.
