How To Get Rid Of Brown Widow Spiders
Brown widow spiders (Latrodectus geometricus) are venomous relatives of the more infamous black widow, and while their bite is typically less potent, their presence around a home or business can still be concerning—especially in areas with high human activity. If you’re a property owner looking to get rid of brown widow spiders on your own, a combination of thorough cleaning, habitat modification, targeted pesticide use, and ongoing monitoring is the most effective DIY approach. Here’s how to get rid of brown widow spiders safely and effectively:
Identify and Locate the Infestation
Start by inspecting areas where brown widows commonly hide:
Outdoors: Under patio furniture, mailboxes, eaves, fence posts, garden equipment, and cluttered storage sheds.
Indoors: In basements, garages, crawl spaces, closets, or behind appliances.
Brown widows often build irregular, tangled webs in low, sheltered areas. Their egg sacs are distinctive—tan to cream-colored with pointed spikes on the surface.
Remove Webs, Egg Sacs, and Spiders Manually
Use a long-handled duster, vacuum, or broom to knock down webs and egg sacs.
Dispose of the vacuum bag or debris in a sealed plastic bag immediately.
Wear gloves during cleanup to protect yourself from potential bites.
This step physically removes the bulk of the population and discourages reestablishment.
Eliminate Attractants and Hiding Places
Brown widows thrive in dark, undisturbed environments. To make your property less hospitable:
Reduce clutter around the exterior of buildings, garages, and sheds.
Seal cracks and gaps around doors, windows, vents, and utility lines.
Trim vegetation away from the structure to minimize harborage areas.
Keep outdoor lighting minimal or switch to yellow “bug” lights, which attract fewer insects—the spider’s prey.
Apply Targeted Insecticide Treatments
If spiders persist, use a residual insecticide labeled for spiders:
Focus on crack and crevice treatments around window frames, doorways, baseboards, and entry points.
Apply insecticide dust or aerosols (such as those containing deltamethrin, bifenthrin, or cypermethrin) to voids, corners, and crevices where webs are found.
For outdoor control, apply a residual perimeter spray 2–3 feet up and out from the building foundation.
Always follow label directions precisely and avoid over-application, especially indoors.
Reduce the Insect Population
Because brown widows feed on other insects, lowering your general pest population indirectly reduces spider activity.
Use outdoor lighting strategically to minimize flying insect attraction.
Treat for ants, flies, and crickets—common spider prey—using integrated pest management (IPM) principles.
Monitor and Reinspect Regularly
After initial cleanup, continue inspecting high-risk areas weekly.
Reapply insecticides as needed, per label intervals.
Watch for new webs or egg sacs as indicators of renewed activity.
Prioritize Safety
Although brown widow bites are typically not life-threatening, they can cause pain and discomfort.
Never handle spiders directly.
Seek medical attention immediately if bitten, especially for children, elderly individuals, or those with allergic reactions.
If your efforts fail to control the infestation or if brown widows are found in sensitive areas (e.g., near children’s play zones, inside commercial buildings, or around entryways), it’s wise to contact our team of licensed pest control professionals. Our experts can identify all hiding areas, apply specialized treatments, and establish long-term preventive strategies safely and effectively.
The Best Way To Get Rid Of Brown Widow Spiders
Our professional spider control is the best and most reliable way to eliminate brown widow spiders because our experts possess the specialized knowledge, equipment, and treatment methods necessary to target both the visible spiders and the hidden breeding sites that most homeowners miss. Brown widows are resilient pests that thrive in protected, hard-to-reach areas, and their ability to reproduce rapidly makes DIY control methods only temporarily effective. Here is why hiring our professionals is the superior solution for managing brown widow spider infestations in homes and businesses.
Accurate Identification and Inspection
Brown widow spiders can easily be mistaken for common house spiders or other widow species. Our professional exterminators are trained to accurately identify brown widows, their egg sacs, and their preferred nesting locations. Through detailed inspections, we locate all areas of activity—including secluded voids, cracks, attics, basements, sheds, and outdoor structures—ensuring that no hidden populations are overlooked.
Targeted and Effective Treatment Methods
Store-bought sprays or foggers rarely reach the deep, protected spaces where brown widows hide. Our pest control professionals use industry-grade insecticides and precise application techniques to eliminate spiders and their egg sacs at the source.
Residual insecticides are applied strategically to baseboards, wall voids, eaves, and exterior perimeters to prevent re-infestation.
Dust formulations are injected into crevices, outlets, and inaccessible spaces where spiders nest.
We also use growth regulators to break the breeding cycle and prevent future outbreaks.
This level of precision and product performance simply can’t be matched with over-the-counter treatments.
Integrated Pest Management (IPM) Approach
Our professionals understand that brown widows thrive where insect prey is abundant. Our professional spider control services address the entire pest ecosystem, not just the visible spiders. Through an IPM approach, we combine:
Habitat modification (removing clutter, sealing cracks, and reducing harborage zones).
Mechanical control (web and egg sac removal).
Targeted chemical applications (long-lasting, regulated products).
Monitoring and prevention strategies (routine inspections and exterior barrier maintenance).
This holistic method delivers long-term relief rather than temporary suppression.
Enhanced Safety and Peace of Mind
Although brown widow bites are typically less dangerous than black widow bites, they can still cause severe pain, cramping, or allergic reactions. Our professional technicians are trained to handle infestations safely, minimizing risk to occupants and pets. We also use EPA-registered products and follow all application and safety protocols, ensuring that treatments are effective yet environmentally responsible.
Long-Term Prevention and Maintenance
Our professional pest control isn’t just about eliminating current infestations—it’s about preventing them from returning. After treatment, our experts will provide:
Ongoing treatment and re-inspection services.
Customized recommendations to keep your property spider-free (e.g., reducing lighting, sealing entry points, managing moisture, or controlling other insects).
This proactive approach ensures year-round security and drastically reduces the chances of future brown widow activity.
Protection for Businesses and High-Risk Environments
For commercial properties—especially restaurants, warehouses, offices, or schools—brown widow infestations pose both liability and reputation risks. Our professional exterminators follow strict safety, documentation, and compliance standards to protect your facility, employees, and customers while maintaining regulatory adherence.
Cost-Effective in the Long Run
DIY spider control may seem cheaper initially, but repeated product purchases, limited effectiveness, and recurring infestations quickly add up. Our professional treatments eliminate the problem at its root and includes preventive services—saving you time, money, and stress over the long term.
Hiring our professional spider control is the most efficient, safe, and lasting way to get rid of brown widow spiders. Our trained experts provide comprehensive inspection, precise treatment, and ongoing prevention to ensure these venomous pests are fully eliminated and don’t return. For property owners who value safety, effectiveness, and peace of mind, our professional spider control is the only truly reliable solution.
