How To Get Rid Of Sac Spiders

Getting rid of sac spiders on your own requires a combination of sanitation, exclusion, and targeted treatment. These spiders—often yellowish or tan with a small body and long legs—are nocturnal hunters that don’t build traditional webs, instead creating small silk sacs for shelter. They’re known to bite when disturbed, so handling an infestation carefully is important. Here is how homeowners and business owners can get rid of sac spiders from their property:

Identify and Locate the Problem

Inspect common hiding areas: Sac spiders often hide in corners, behind picture frames, under furniture, around window and door frames, baseboards, ceiling edges, and in closets.
Look for their silk sacs: These small, papery silk retreats (about the size of a dime) are usually found along walls, ceilings, or behind objects.
Check outdoors as well: They may shelter under siding, behind shutters, or in eaves before entering your structure.

Eliminate Attractants

Reduce indoor insect activity: Sac spiders are hunters that feed on small insects. Keep your space free of other pests to make it less appealing.
Maintain cleanliness: Vacuum regularly, especially in corners, ceilings, and behind furniture. Remove spider sacs, egg sacs, and live spiders when seen.
Eliminate clutter: Cardboard boxes, stored items, and piles of papers create ideal hiding places.

Seal Entry Points

Inspect and repair gaps: Caulk around window and door frames, utility openings, vents, and cracks in foundations or siding.
Install weatherstripping: Use tight-fitting door sweeps and seals around windows to block access.
Replace torn screens: Even small rips in window or door screens can allow spiders inside.

Use Physical and Mechanical Controls

Vacuuming: Safely remove spiders and sacs using a vacuum with a hose attachment. Dispose of the vacuum bag or empty the canister immediately outdoors.
Sticky traps: Place non-toxic glue traps along baseboards, behind furniture, and near corners to monitor and capture spiders.

Apply Targeted Treatments

Use residual insecticides carefully: Apply a labeled spider or general pest control spray (e.g., with pyrethrins or bifenthrin) along baseboards, cracks, wall-ceiling junctions, and around entry points.
Aerosol or dust formulations: For crevices, attics, or behind electrical outlets, a residual dust (like deltamethrin dust) can be effective.
Outdoor barrier: Apply a perimeter treatment around the foundation, focusing on windows, doors, siding gaps, and eaves.

Maintain Ongoing Prevention

Keep exterior lighting minimal or switch to yellow bulbs to reduce the insects that attract spiders.
Trim vegetation, shrubs, and tree limbs away from the structure to reduce outdoor harborage sites.
Continue monthly inspections, especially during late summer and early fall when sac spiders are most active indoors.

A successful DIY approach to sac spider control depends on consistent cleaning, sealing entry points, and precise application of insecticides. However, because sac spiders often nest in hard-to-reach areas and may indicate a larger insect problem, our professional pest control is more thorough and long-lasting.

The Best Way To Get Rid Of Sac Spiders

Our professional spider control is the most effective and reliable way to eliminate sac spiders because our experts bring specialized knowledge, advanced products, and precise application techniques that go far beyond what most homeowners or business owners can achieve with DIY methods. Sac spiders are particularly troublesome because they hide in concealed areas, build small silk retreats that are easy to overlook, and often enter structures from the outside.

Accurate Identification and Inspection

Our professional exterminators begin with a thorough inspection to identify the specific spider species and locate areas of activity. Sac spiders are often mistaken for other small hunting spiders, and proper identification is critical to selecting the right treatment strategy.

Our experts know where to look — ceiling corners, upper walls, window frames, and behind fixtures — where sac spiders commonly build their sacs.
We also inspect both the interior and exterior of the property to locate entry points and outdoor harborage areas that may be sustaining the infestation.

Targeted and Professional-Grade Treatments

Our professionals use EPA-approved, commercial-grade insecticides that are not available to the general public. These formulas are longer-lasting, more effective against spiders and their prey insects, and applied with precision.

Treatments are placed strategically in cracks, voids, ceiling junctions, basements, attics, and other areas that are often missed during DIY efforts.
Our professionals also use specialized dusts, aerosols, and microencapsulated residuals that provide extended protection in hard-to-reach areas where sac spiders nest.
We integrate insect management for the underlying pest populations that attract spiders in the first place.

Comprehensive, Long-Term Solutions

Our professional pest control services don’t just treat visible spiders—we implement a complete integrated pest management (IPM) plan designed to prevent re-infestation.

Our technicians identify and seal access points, remove conducive conditions, and recommend structural or sanitation improvements.
Ongoing protective visits ensure the treatment remains effective, especially during seasonal activity spikes.
Our professionals also target outdoor nesting and entry zones, creating a protective perimeter barrier around the entire structure.

Safety and Precision

Spider control products, when misused, can pose risks to people, pets, and property. Our professional technicians are trained and licensed to apply treatments safely and effectively, minimizing exposure while maximizing results.

We know how to apply treatments in sensitive environments—such as food service areas, offices, or homes with children and pets—without compromising safety.
We also ensure compliance with local and federal pest control regulations, something DIY users may overlook.

Expertise in Behavior and Prevention

Sac spiders are nocturnal and elusive, often migrating indoors from outdoor habitats during cooler months. Our professionals understand these behavioral patterns and adapt our approach accordingly.

We anticipate seasonal movements, nesting preferences, and reproduction cycles.
We provide expert guidance on long-term prevention, including lighting adjustments, vegetation management, and moisture control around the property.

Time and Cost Efficiency

While DIY efforts can involve repeated applications, wasted products, and missed problem areas, our professional treatments deliver faster and more reliable results.

We can resolve a sac spider infestation in a fraction of the time it takes for an untrained person.
In the long run, this saves money by preventing costly re-infestations or structural damage from associated insect pests.

Our professional spider control is the best solution for sac spider infestations because we combine accurate identification, specialized treatments, safety expertise, and long-term prevention. Home and business owners benefit from working with our licensed pest control team that understands local spider behavior, seasonal activity, and environmental factors that drive infestations.
