Professional Spider Control Services
Finding spiders in your home can be unsettling. While most spiders in Washington are harmless and beneficial to our ecosystem, they become pests when they invade our living spaces, build unsightly webs, and create a sense of unease. At Sparrow’s Pest Control, we understand that for many, a spider problem is a serious concern. We offer a professional solution that not only removes current spiders and their webs but also creates a lasting barrier to keep them from returning.
Identifying Common Spiders in the Pacific Northwest
Knowing which spiders are common in our region can help alleviate fears and determine the best course of action.
- Giant House Spider: Often causing the most alarm due to its large size and incredible speed, the Giant House Spider is a common indoor resident. They are typically brown with chevron-like markings on their abdomen. Despite their intimidating appearance, their bite is harmless to humans and they are excellent at controlling other pests.
- Hobo Spider: Frequently confused with other brown spiders, the Hobo Spider builds funnel-shaped webs in dark, moist areas like woodpiles, retaining walls, and foundations. While their reputation for a dangerous bite is now largely debated by experts, they are still considered a pest that requires professional management due to their tendency to wander indoors in late summer and fall.
- Black Widow Spider: The most medically significant spider in our area, the Black Widow is easily identified by the red hourglass marking on the underside of its shiny, black abdomen. They prefer dark, undisturbed locations like woodpiles, sheds, crawlspaces, and cluttered garages. A Black Widow bite requires immediate medical attention.

The Sparrow’s Web-Free Shield: Our Spider Control Process
Our service is designed to provide both immediate cosmetic improvement and long-lasting protection from future spider invasions.
1. Detailed Inspection Our technician starts by inspecting your property’s exterior to identify high-activity areas, entry points, and conditions that attract spiders, such as other insect populations and exterior lighting placement.
2. Thorough De-Webbing A critical first step is the physical removal of all accessible spider webs, nests, and egg sacs from the eaves, window frames, doorways, and corners of your home’s exterior. This not only provides an instant clean appearance but also removes the spiders’ existing homes and future generations.
3. Professional Barrier Treatment We apply a professional-grade liquid residual insecticide to the exterior of your property. This powerful barrier is meticulously applied around the foundation, along eaves, and around all potential entry points like windows and doors. The product is designed to be undetectable to spiders, who receive a lethal dose upon contact, and it remains effective for weeks.
4. Interior Spot Treatment (As Needed) For active infestations inside the home, we can apply targeted spot treatments to cracks, crevices, and other common spider hiding places, ensuring complete removal while minimizing product use indoors.

Why Choose a Professional for Spider Control?
Store-bought spider sprays offer a temporary solution at best. A professional service provides comprehensive and lasting results.
- Long-Lasting Products: The residual products we use are far more potent and weather-resistant than anything available to consumers, providing a protective barrier that lasts for up to 90 days.
- Proper Equipment and Safety: Effectively treating a home’s exterior, especially two-story eaves and high peaks, requires specialized equipment. Our technicians are trained to perform these applications safely and effectively.
- Comprehensive Approach: We don’t just spray. The combination of de-webbing, treating, and providing recommendations for prevention (like changing exterior light bulbs to less-attractive yellow lights) addresses the problem from all angles.
Frequently Asked Questions
For the most part, no. The vast majority of spiders you will encounter indoors are harmless nuisance pests like the Giant House Spider. The only medically significant spider commonly found in our area is the Black Widow, which typically prefers to live outdoors in undisturbed areas. However, any spider bite can potentially become infected, so it’s always best to exercise caution.
Our professional exterior barrier treatments are designed to last for 60-90 days, depending on weather conditions. For year-round control and to prevent the major influx of spiders in the fall, we highly recommend our recurring seasonal pest protection plan.
Yes. The professional product we use for the exterior barrier is effective against a wide range of crawling insects. While it’s specifically applied to target spiders, it will also help control ants, beetles, and other common pests attempting to enter your home, which in turn reduces the spiders’ primary food source.
A large spider population is usually an indicator of two things: a healthy supply of other insects for them to eat, and ideal environmental conditions. Exterior lights left on at night attract flying insects, which then attract spiders. Dense vegetation, clutter, and moisture around your foundation also provide perfect harborage for them.
