Spider Control for Charleston-Area Homes & Businesses

Say goodbye to unwanted eight-legged guests with professional spider control built around your property.
Barrier Pest Services provides professional spider control and extermination across Charleston, Berkeley and Dorchester counties. Our licensed technicians bring years of hands-on experience treating the spider activity common to Lowcountry homes, garages, porches and crawlspaces. While many spiders are harmless, increased activity can point to other pest issues around your property, and we treat both the spiders and the conditions that draw them in.
Why Spiders Are Common in Lowcountry Properties
The Lowcountry creates ideal conditions for spider activity. Warm weather, humidity, landscaping, crawlspaces and outdoor lighting all attract insects, and insects attract spiders. Common spider problem areas include:
- Porches, patios and garages
- Crawlspaces, attics and storage areas
- Exterior lighting and rooflines
- Sheds, woodpiles and outdoor structures
- Landscaping near the foundation
Frequent spider activity often means there’s a larger insect population nearby. Exterior lights left on overnight, in particular, draw moths and flying insects, and spiders follow that food supply straight to your porch and eaves.
Common Spiders We Treat
Identifying the species helps us determine the right treatment approach. Our technicians commonly treat:
- Black Widow Spiders: Venomous spiders often found in dark, quiet spaces like garages, crawlspaces, sheds and woodpiles. Females are shiny black with a red hourglass marking and deliver a bite that needs medical attention.
- Brown Recluse Spiders: Light brown spiders with a violin-shaped marking, usually found in undisturbed areas like stored boxes, closets and seldom-used spaces. They aren’t aggressive, but a bite can cause a painful skin reaction and should be checked by a doctor.
- Wolf Spiders: Fast-moving hunting spiders that often enter homes, garages and storage areas through ground-level gaps.
- Orb Weavers: Outdoor spiders that build large webs near porches, lights, rooflines and landscaping.
- House Spiders: Common indoor spiders found in corners, closets, storage areas and less-used rooms.
Our Spider Control Process
Effective spider control requires more than spraying the spiders you see. We focus on reducing activity and treating the conditions that let spiders return.
- Inspection: We check for spider activity, webs, egg sacs and insect pressure around the property.
- Web removal: We remove accessible webs and egg sacs from common activity areas.
- Targeted treatment: We treat the areas where spiders hide, travel and build webs.
- Exterior protection: We apply treatment around entry points, eaves, porches, garages and foundation areas.
- Prevention guidance: We explain what may be attracting spiders and how to reduce future activity.
How to Reduce Spider Activity Between Services
You can make your property less attractive to spiders by reducing insects, clutter and hiding spots.
- Remove webs from porches, corners and exterior lighting
- Reduce clutter in garages, sheds and storage areas
- Seal gaps around doors, windows and utility lines
- Keep landscaping trimmed away from the foundation
- Switch porch lights to amber or warm bulbs, which attract fewer insects than white or blue-spectrum lighting
These steps support professional spider control and help reduce the areas where spiders can hide. If activity picks up again between visits, we’ll come back and address it.
