Say Goodbye to these Creepy Crawlers for Good

Seeing webs in corners, spiders near baseboards, or activity in the garage? Our Boise spider control service eliminates active infestations, removes webs, and creates a protective barrier so spiders don’t come back. Request a free inspection and same-day scheduling at 208-795-3298.

Why Spiders Show Up in Treasure Valley Homes

Spiders follow food. When flying and crawling insects increase around exterior lights, door thresholds, and eaves, spiders move in to hunt. Boise’s dry summers and cold winters also push them toward consistent moisture and shelter—garages, crawl spaces, basements, and quiet storage areas. If you’re finding regular spider activity indoors, you likely have favorable harborage, entry points, and an underlying insect food source.

• Common issues spiders cause
• Webs and egg sacs collecting in eaves, corners, and storage areas
• Startle/comfort concerns for kids and pets
• Occasional medically important species (e.g., black widows) in protected, undisturbed spots such as woodpiles, sheds, and under deck stairs

Spiders We Commonly See in Boise-Metro

• Cellar spiders (daddy longlegs-type), common house spiders, and cobweb spiders in corners and window frames
• Wolf spiders and grass spiders that wander in from landscaping and garages
• Jumping spiders on sunny sills and interior walls
• Black widows in dark, undisturbed exterior sites such as woodpiles, valve boxes, and sheds
• Hobo spiders and other funnel weavers around ground-level foundation gaps and cluttered storage

Note on risk: Brown recluse spiders are not established in Idaho; rare, transported individuals may appear but sustained populations haven’t been verified locally. Hobo spiders are no longer considered of medical concern by experts; black widows remain the primary medically important species to watch for in our area.

Where Spiders Hide (Indoors & Outside)

Indoors: garage corners, behind stored boxes, under stairs, inside utility rooms, crawl spaces, window wells, and quiet ceiling corners.
Outside: under eaves, behind downspouts, in valve boxes, under patio furniture, beneath deck stairs, woodpiles, and dense shrubs touching siding.

Signs to watch for

• Fresh webs and egg sacs reappearing after you clean
• Night activity around porch lights and door thresholds
• Shed skins and live spiders along baseboards and window frames

Our Spider Control Process

1) Same-Day Inspection and Species Identification

We trace conducive conditions (insect prey, moisture, vegetation touching the home) and locate hot spots: garages, crawl spaces, soffits/eaves, light fixtures, and foundation gaps. Service area includes Boise, Meridian, Nampa, Caldwell, Eagle, Kuna, Star, Middleton, and Garden City.

2) Targeted Knockdown and Web Removal

Precision applications where spiders live and hunt (interior voids as needed, exterior seams, and protected harborage)

Web removal at eaves, porch ceilings, soffits, play structures, sheds, and fence lines

Focused black widow treatments for garages, woodpiles, and utility boxes when present

3) Exterior Barrier and Entry-Point Hardening

Perimeter treatment to stop new spiders and insect prey from establishing

Recommendations to seal utility penetrations and weather-strip thresholds

Vegetation and clutter guidance so exterior zones don’t continually re-seed new webs

4) Follow-Up and Maintenance

Quarterly protection plans keep a fresh barrier in place through seasonal shifts, with de-webbing and retreatment of pressure points so activity doesn’t rebound.

Black Widow Attention Areas

Widows prefer dry, undisturbed corners and clutter near ground level. We target garages, sheds, valve boxes, deck undersides, and wood piles with careful applications and web removal. Gloves and visual checks are recommended when moving stored items, firewood, or patio furniture.

DIY vs Professional

Knocking down visible webs helps, but without treating harborage and addressing the underlying insect food source, spiders return quickly. Store-bought sprays can leave gaps, especially in complex eave systems and crawl spaces. A species-aware program with routine maintenance provides better long-term results.

Prevention Checklist

Reduce outside night lighting or switch to warmer bulbs that attract fewer insects

Trim plants and shrubs back from siding and keep mulch/rock from bridging to foundation gaps

Seal door sweeps and utility penetrations, fix torn screens, and close gaps at garage weather-stripping

Store boxes off the floor; use sealed bins; keep woodpiles away from structures

Keep basements and crawl spaces dry and ventilated
