How to Get Rid of Wolf Spiders in Your House for Good
Are you sharing your home with unwanted eight-legged guests? The sight of a large, hairy spider scurrying across your floor can be unsettling, and if that spider is a wolf spider, it’s understandable to want it gone. Unlike some other spiders, wolf spiders are often active hunters, meaning they’re not content to stay hidden in webs. This guide provides a comprehensive, actionable plan to effectively eliminate wolf spiders from your house and prevent their return.
Understanding the Enemy: Identifying Wolf Spiders and Their Habits
Before tackling the problem, it’s crucial to identify your foe. Wolf spiders are often mistaken for other large spiders, but they have distinct characteristics:
- Appearance: They are typically large (up to 2 inches in body length, including legs), hairy, and brown or grey. They have a distinctive eye arrangement – eight eyes arranged in three rows.
- Behavior: Unlike web-spinning spiders, wolf spiders are active hunters. They roam the ground searching for prey like insects and smaller spiders. They are also known for their speed.
- Habitat: They prefer to live outdoors, under rocks, in leaf litter, and in gardens. They venture indoors seeking shelter, prey, or warmth, especially during colder months.
- Bite: While wolf spider bites are venomous, they are generally not considered medically significant to humans. Bites can cause localized pain, redness, and swelling.
Step-by-Step Guide to Wolf Spider Elimination
Successfully ridding your home of wolf spiders involves a multi-pronged approach. Here’s a breakdown of effective strategies:
1. Inspection and Identification of Entry Points:
- Thorough Inspection: Carefully inspect your home’s interior and exterior, focusing on areas where spiders could enter:
- Around windows and doors
- Cracks in the foundation and walls
- Gaps around pipes and wires
- Vents and crawl spaces
- Seal Entry Points: Use caulk, weather stripping, and expanding foam to seal any cracks, gaps, and openings you find. This is a crucial preventative measure.
- Thorough Inspection: Carefully inspect your home’s interior and exterior, focusing on areas where spiders could enter:
2. Immediate Spider Removal:
- Vacuuming: The most immediate and effective method for removing spiders you see is vacuuming. Use the hose attachment to suck up spiders and their egg sacs (if any). Empty the vacuum bag or canister immediately outdoors.
- Trapping: Place sticky traps in areas where you’ve seen wolf spiders. These traps will catch spiders as they move around.
- Physical Removal: If you’re brave, you can use a container and a piece of cardboard to capture and relocate the spider outdoors.
3. Insecticide Application (Use with Caution):
- Considerations: Insecticides should be used as a last resort and always with caution, especially if you have children or pets. Always read and follow the product label instructions.
- Types of Insecticides:
- Contact Sprays: These kill spiders on contact.
- Residual Sprays: These leave a film that kills spiders when they walk across treated surfaces.
- Insecticide Dusts: These can be applied to cracks and crevices.
- Application: Apply insecticides to areas where spiders are likely to travel, such as baseboards, corners, and around windows and doors.
4. Eliminating the Food Source:
- Control Insect Populations: Wolf spiders are predators, and their primary food source is insects. Reduce the number of insects in your home and around your property to starve them out.
- Keep Your Home Clean: Regularly clean up crumbs, spills, and food debris, which attract insects.
- Proper Trash Disposal: Seal trash cans tightly and dispose of garbage regularly.
5. Outdoor Prevention Strategies:
- Clear Debris: Remove leaf litter, woodpiles, and other debris from around your foundation. These provide hiding places for wolf spiders.
- Maintain Landscaping: Keep bushes and shrubs trimmed away from your house to prevent spiders from using them as bridges to enter your home.
- Outdoor Lighting: Consider using yellow or sodium vapor lights outdoors, as they are less attractive to insects than standard white lights.
Preventing Wolf Spiders from Returning: Long-Term Strategies
Once you’ve eliminated existing wolf spiders, focus on long-term prevention:
- Regular Cleaning: Vacuum and dust regularly to remove spider webs, egg sacs, and potential food sources.
- Ongoing Inspections: Periodically inspect your home for new entry points or signs of spider activity.
- Professional Pest Control: Consider hiring a professional pest control service for regular inspections and treatments, especially if you have a persistent spider problem.
