How To Get Rid Of Crab Spiders

Crab spiders can be unsettling to find in your home or business, especially since these spiders often lurk in flowers, plants, and quiet corners waiting for prey. While they are generally harmless to humans and even beneficial outdoors, an indoor infestation or frequent sightings can indicate conditions that are attracting them—usually an abundance of insects or convenient hiding spots. Here are the best ways for property owners to get rid of unwanted crab spiders effectively and safely:

Identify and Eliminate Attractants

Crab spiders enter homes and businesses primarily in search of food (insects) or shelter. Reducing what attracts them is the first step:

Control other insects: Since crab spiders feed on flies, moths, gnats, and other pests, reduce these populations with fly traps, proper sanitation, and professional pest treatments.
Turn off outdoor lights at night: Light attracts insects, which in turn attracts spiders. Use yellow or sodium vapor bulbs that are less appealing to bugs.
Seal gaps and entry points: Inspect windows, door frames, vents, and utility openings. Use caulk or weatherstripping to block possible entryways.

Remove Hiding and Breeding Areas

Crab spiders prefer cluttered, quiet areas where they can ambush prey:

Clear vegetation near the structure: Trim bushes, flowers, and plants at least 1–2 feet away from exterior walls and entry points.
Declutter storage areas: Garages, basements, and attics often harbor spiders. Store items in sealed plastic containers instead of cardboard boxes.
Vacuum and dust regularly: Focus on corners, behind furniture, window sills, and ceiling edges where spiders might hide or build nests.

Use Natural and DIY Control Methods

If you prefer eco-friendly or low-impact solutions, try:

Vacuuming up spiders directly: Safely removes spiders, webs, and egg sacs without chemicals.
Essential oils: Mix peppermint, tea tree, or citrus oil with water and spray around entry points and baseboards—these scents can deter spiders.
Sticky traps: Place non-toxic glue traps in corners, behind furniture, or near windows to monitor and capture crab spiders.

Apply Targeted Chemical Treatments (When Needed)

If the infestation persists:

Use a residual insecticide labeled for spiders: Apply along baseboards, cracks, and exterior foundations. Products containing bifenthrin, deltamethrin, or lambda-cyhalothrin are typically labeled for spiders.
Treat outdoor areas: Focus on the foundation perimeter, window frames, and eaves where spiders hunt and rest.
Always follow safety instructions: Keep pets and children away from treated zones until dry, and wear gloves and protective gear during application.

Prevent Future Infestations

Maintain regular pest control treatments: Our professional service plans can target both spiders and the insects they feed on.
Inspect regularly: Check outdoor lighting fixtures, window screens, and vegetation each season.
Keep humidity low indoors: Use dehumidifiers in basements and crawl spaces to make conditions less appealing to insects and spiders.

If crab spiders continue appearing despite your efforts, or if you notice many insects inside the property, it’s best to hire our licensed pest control professionals. Our professionals can identify and treat the source of insect activity, apply safe, targeted spider treatments, and create a long-term barrier to prevent re-entry.

The Best Way To Get Rid Of Crab Spiders

Our professional spider control is the most effective way to get rid of crab spiders from a home or business because we address the problem comprehensively, safely, and long-term. While DIY methods can be effective at removing individual spiders or reducing sightings, they rarely eliminate the underlying causes that attract spiders or prevent re-infestation. Here’s why hiring our trained pest control specialists is the best approach:

Expert Identification

Crab spiders can be mistaken for other spider species, and each type may require a slightly different approach for effective control. Our professionals can:

Accurately identify crab spiders and any other spider species present.
Assess the severity of the infestation, including hidden egg sacs and webs.
Pinpoint the areas where spiders are most likely entering or nesting.

This precise identification ensures that treatments are targeted and effective, rather than broad and potentially ineffective.

Targeting the Source, Not Just the Symptoms

Crab spiders enter homes and businesses in search of prey and shelter. Simply killing the visible spiders doesn’t solve the root cause. Our professionals:

Inspect both interior and exterior areas for insect populations that attract spiders.
Remove or treat the environmental conditions that allow spiders to thrive, such as excess vegetation, cluttered storage, and entry points.
Treat areas like baseboards, attics, crawl spaces, and exterior foundations, which homeowners often overlook.

By addressing the source, our professional control prevents new spiders from returning.

Safe and Effective Use of Treatments

Our professional exterminators have access to tools and products not typically available to the public, and we know how to apply them safely:

Residual insecticides are applied strategically to maximize effectiveness and minimize exposure to humans and pets.
Our professionals know the correct dosages and locations for treatments, reducing the risk of ineffective DIY sprays or chemical misuse.
We can integrate eco-friendly options when preferred, maintaining a safe environment without compromising results.

Monitoring and Long-Term Prevention

Crab spider control is not always a one-time job. Our professionals provide ongoing solutions:

We can implement monitoring systems to detect new spider activity early.
Seasonal treatments prevent future infestations.
Guidance on habitat modification—trimming vegetation, sealing cracks, managing insect prey populations—ensures the property remains less attractive to spiders over time.

Time and Peace of Mind

Spider infestations can be persistent, especially in larger homes or commercial properties. Hiring our professionals:

Saves time and effort, as DIY methods often require repeated attempts.
Provides peace of mind knowing that the infestation is being treated by our trained experts who understand spider behavior and control techniques.
Reduces the risk of incomplete control, which can result in ongoing sightings, anxiety, and potential damage to stored goods or structures.

Our professional spider control doesn’t just get rid of visible crab spiders—it eliminates the conditions that attract them, prevents future infestations, and ensures the property is safe and pest-free. This comprehensive approach is far more effective, reliable, and efficient than any DIY method.
