Effective spider control involves thorough cleaning, sealing entry points, and targeted treatments to eliminate large house spiders safely.
Understanding Large House Spiders and Their Habits
Large house spiders can be intimidating, but knowing their behavior is key to managing them effectively. These arachnids are often nocturnal hunters, preferring dark, undisturbed corners such as basements, attics, and behind furniture. Unlike their smaller cousins, large house spiders are capable of spinning extensive webs and can sometimes be mistaken for more dangerous species due to their size.
Most large house spiders feed on insects, making them beneficial in controlling pests. However, their presence inside homes can cause discomfort or fear. They tend to enter houses through cracks, gaps around windows and doors, or open vents. Moisture-rich areas attract them since these environments support their prey and provide suitable hiding spots.
Identifying the exact species helps determine the best removal method. Common large house spiders include the Giant House Spider (Eratigena atrica) and the Huntsman Spider (Heteropoda venatoria). While generally non-aggressive toward humans, their size alone can cause alarm. Understanding that they rarely bite unless provoked is important for calm and effective control measures.
Preventive Measures to Keep Large House Spiders at Bay
Prevention is the first line of defense against large house spiders invading your living space. The goal is to make your home less attractive and accessible to these eight-legged visitors. Start by keeping your home clean and clutter-free; spiders love hiding in piles of clothes, boxes, or stacks of newspapers. Regular vacuuming removes webs, eggs, and potential food sources like other insects that attract spiders.
Sealing cracks around windows, doors, baseboards, and utility pipes blocks common entry points. Use weather stripping or caulk for a tight seal—this simple step drastically reduces spider traffic indoors. Outdoor lights attract insects at night which in turn lure spiders close to your home; switching to yellow or sodium vapor bulbs reduces this effect significantly.
Controlling humidity also plays a vital role since many large house spiders thrive in damp environments. Use dehumidifiers in basements or poorly ventilated rooms to create less hospitable conditions for them. Removing leaf litter and debris near your foundation cuts down on outdoor spider habitats where they might nest before wandering inside.
Natural Repellents That Work
If you prefer chemical-free options, several natural substances can deter large house spiders effectively:
- Peppermint Oil: Spiders dislike its strong scent; spraying a diluted solution around doorways and windows can keep them away.
- Vinegar: A mixture of vinegar and water sprayed on webs or corners disrupts their sensory receptors.
- Citrus Peels: Placing lemon or orange peels near entry points acts as a mild repellent.
- Cedarwood: Using cedar blocks or shavings in closets discourages spider activity due to its aroma.
These methods are safe for households with pets or children but should be reapplied regularly for sustained effectiveness.
Tackling Existing Large House Spider Infestations
Once you’ve spotted large house spiders inside your home, swift action is necessary to prevent breeding and further spread. Mechanical removal using a vacuum cleaner with a hose attachment is an efficient first step—dispose of the vacuum bag immediately afterward outdoors to avoid re-infestation.
For targeted elimination, insecticides labeled specifically for spider control are available in sprays or dust forms. Apply these carefully along baseboards, corners, behind furniture, and other spider-prone areas following manufacturer instructions strictly for safety reasons.
Sticky traps placed strategically catch wandering spiders before they settle into permanent spots indoors. These traps serve as both monitoring tools and control measures without introducing chemicals.
Professional pest control services offer advanced treatments such as residual insecticides that last longer or specialized baits that attract spiders indirectly by targeting their prey insects.
The Role of Spider Eggs in Infestation Control
Large house spiders lay egg sacs containing dozens to hundreds of eggs hidden within webs or crevices. Ignoring these sacs allows rapid population growth inside your home during warmer months.
Locate egg sacs during cleaning sessions—these look like small white or yellowish silk pouches—and remove them carefully using gloves or vacuuming techniques mentioned earlier.
Destroying egg sacs significantly reduces future spider numbers by preventing hatchlings from emerging undetected.
The Science Behind Spider Control Products
Spider control products come in various formulations designed to target different stages of the spider life cycle while minimizing risks to humans and pets.
| Product Type | Main Ingredients | Description & Use |
|---|---|---|
| Aerosol Sprays | Pyrethrins & Piperonyl Butoxide | Kills on contact; ideal for immediate spider elimination in visible areas. |
| Diatomaceous Earth (Dust) | Diatomaceous earth (silica-based) | Abrasive powder that dehydrates spiders; best applied in cracks and crevices. |
| Boric Acid Baits | Boric acid mixed with attractants | Toxic to insects feeding on baits; indirectly reduces spider food sources. |
Choosing the right product depends on infestation severity and household considerations like children or pets present.
The Importance of Safe Handling While Removing Spiders
Safety must come first when dealing with large house spiders despite their generally non-aggressive nature.
Wearing gloves protects against accidental bites while handling webs or egg sacs.
Avoid crushing spiders directly with bare hands; this may provoke defensive bites or spread allergens from body parts.
If using chemical sprays indoors, ensure proper ventilation by opening windows and doors during application.
Keep pets away from treated areas until products dry completely according to label instructions.
Dispose of captured spiders outdoors far from entrances so they cannot re-enter your home.
Mistakes To Avoid During Spider Removal
- Ineffective partial cleaning: Only removing visible webs without addressing hidden spots lets populations rebound quickly.
- Narrow focus on killing adults: Ignoring eggs means repeating infestations despite efforts.
- Poor sealing efforts: Leaving gaps around doors/windows invites constant new arrivals.
- Mismatched product use: Using repellents alone without physical removal rarely solves infestations fully.
Avoiding these pitfalls increases chances of long-term success at keeping your home spider-free.

Frequently Asked Questions
How To Get Rid Of Large House Spiders Using Cleaning Methods?
Thorough cleaning is essential to get rid of large house spiders. Regular vacuuming removes webs, eggs, and insects that attract spiders. Keeping your home clutter-free eliminates their hiding spots, making your living space less inviting for these arachnids.
What Are the Best Ways To Get Rid Of Large House Spiders By Sealing Entry Points?
Sealing cracks and gaps around windows, doors, baseboards, and utility pipes prevents large house spiders from entering your home. Use caulk or weather stripping to create tight seals, which drastically reduces spider traffic indoors and helps keep them outside where they belong.
Can Targeted Treatments Help To Get Rid Of Large House Spiders Safely?
Targeted treatments like insecticides or natural repellents can effectively reduce large house spider populations. Always choose safe options and apply them in areas where spiders frequent, such as basements and attics, to minimize risks to humans and pets.
How Does Controlling Humidity Help To Get Rid Of Large House Spiders?
Large house spiders thrive in damp environments. Using dehumidifiers in basements or poorly ventilated rooms reduces moisture levels, making your home less hospitable for spiders and their prey. Controlling humidity is a key preventive measure in spider management.

Conclusion – How To Get Rid Of Large House Spiders
Successfully getting rid of large house spiders demands a multi-pronged approach combining prevention, targeted removal, environment management, and safe use of control products. Regular cleaning paired with sealing entry points denies these arachnids easy access while natural repellents provide ongoing deterrence without harsh chemicals.
