Spiders are useful creatures outdoors. Inside your home, they’re a different story. Whether you’re dealing with a full-blown infestation or just want to prevent them from setting up shop in the first place, there are effective strategies that don’t require calling an exterminator every season. Most of them involve making your home less appealing to spiders before they show up.
Here’s a complete breakdown of how to keep your home free from spiders using both prevention and targeted removal.
Seal Up Entry Points First
Spiders don’t teleport into your house. They walk in through gaps that are often easy to fix. Before you worry about anything inside, do a thorough inspection of the exterior of your home.
Check around door and window frames for gaps where weatherstripping has worn away or caulk has cracked. Look where utility pipes and cables enter the house — these penetrations are frequently left with oversized gaps around them. Inspect the foundation for cracks, particularly in older homes. Also check screens on windows and vents. Small tears that seem minor are large enough for most spider species to use.
Hardware stores carry foam backer rod, caulk, and weatherstripping in every form factor. Sealing these entry points takes an afternoon and prevents far more than just spiders — it also helps with insects, mice, and energy loss.
Eliminate Their Prey and You Eliminate Them
Spiders move into a space because there’s food — specifically, other insects. If you reduce the overall insect population in and around your home, spiders have no reason to stay. Address outdoor lighting first: bright white lights attract flying insects at night, which in turn attracts spiders. Switching to amber or yellow LED bulbs dramatically reduces this effect without sacrificing illumination.
Make sure door seals are tight and that screens don’t have gaps. Standing water near the foundation attracts mosquitoes, which attract other predators. Firewood stored directly against the house creates habitat for all kinds of insects and spiders — move it at least 20 feet away and store it elevated off the ground if possible.
Keep the Interior Less Hospitable
Spiders love undisturbed corners, clutter, and dark spaces where they can build webs and stay out of sight. Regular cleaning makes your home structurally less appealing to them.
Vacuum corners, baseboards, and window frames regularly. Pull furniture away from walls periodically and clean the space behind it. Pay special attention to areas under sinks, in closets, in the garage, and in any storage room where boxes sit undisturbed for long periods. Cardboard boxes are particularly attractive because they retain moisture and provide easy hiding spots — switching to plastic bins with lids is a simple upgrade that makes a meaningful difference.
Organizing your kitchen and living spaces also reduces the overall insect population that feeds spiders. Clean up food residue promptly, keep trash in sealed containers, and repair any leaking pipes or faucets that create moisture attractive to insects.

Remove Webs Immediately and Consistently
When a spider builds a web and nothing disturbs it, that’s a signal to the spider that it’s found a good location. Removing webs promptly sends the opposite message. Use a vacuum to pull down webs rather than sweeping them — this also captures any egg sacs before they hatch.
Check ceiling corners, the area behind and above window treatments, light fixtures, the garage ceiling, and basement joists. These are the high-frequency spots. Make web removal part of your regular cleaning routine rather than treating it as a one-time fix.
Natural Repellents That Actually Work
Several natural substances interfere with spiders’ ability to sense their environment or simply make surfaces unpleasant for them to walk on. These work best as part of a broader prevention strategy rather than as a standalone solution.
Peppermint oil is the most widely tested and consistently effective natural repellent. Mix 15 to 20 drops of pure peppermint essential oil (not extract) into a 32-ounce spray bottle of water and shake well before each use. Spray along baseboards, window sills, door frames, and anywhere you’ve spotted activity. Refresh every week or two, or after cleaning. The smell dissipates for humans quickly but remains detectable for spiders.
White vinegar applied in a 50/50 solution with water works similarly, though the smell is more noticeable. Spray along the same areas as peppermint oil. Both can be alternated — some people rotate them to prevent spiders from habituating to a single deterrent.
Citrus peels placed near entry points or in corners add additional deterrence. Dried citrus also works — you can place dried lemon or orange peel in a small sachet and tuck it into closets or storage areas. Replace monthly as the scent fades.
Cinnamon works as a contact deterrent rather than an airborne one. Lightly dusting cinnamon powder along windowsills or near entry points discourages spiders from crossing. Use sparingly on surfaces where residue would be visible.
When Natural Methods Aren’t Enough
For persistent infestations or fast-acting control, spider sprays and residual insecticides are effective. Look for products containing lambda-cyhalothrin or deltamethrin. Apply along baseboards, under furniture, and in other low-traffic areas where spiders typically travel. Always follow label directions and keep children and pets away from treated surfaces until dry.
Glue traps placed in corners and along baseboards don’t kill spiders directly but catch them as they move through the space. They’re also a useful diagnostic tool — if you’re catching a lot of spiders in a specific area, that tells you where to focus other prevention efforts.
Which Spiders Are Actually Dangerous
In North America, the overwhelming majority of household spiders are harmless to humans. The species you’re most likely to encounter in your home — house spiders, cellar spiders (daddy longlegs), wolf spiders — are nuisances but not threats.
There are two species worth knowing and being cautious about:
The black widow is found across most of the United States and is recognizable by the red hourglass marking on the underside of its abdomen. It builds irregular, sticky webs close to the ground in undisturbed areas like garages, woodpiles, and crawlspaces. Its venom is medically significant. Bites are painful and can cause muscle cramping and nausea, though fatalities are extremely rare with modern medical treatment.
The brown recluse is found primarily in the south-central United States and is identified by the violin-shaped marking on its back and its six eyes (most spiders have eight). It prefers dark, undisturbed spaces like closets, attic insulation, and cardboard boxes. Its bite can cause necrotic tissue damage in some cases, though severe reactions are uncommon.
If you see either of these species in your home, targeted removal with a jar-and-card method or a vacuum is more effective than spray, since these spiders tend to hide rather than walk across open surfaces where spray residue would contact them.
Professional Pest Control: When It Makes Sense
If you’ve worked through all of the above and the problem persists, or if you’ve identified a significant brown recluse or black widow presence in your home, professional treatment makes sense. A licensed pest control technician can apply residual products in wall voids and other inaccessible areas and give you a structural assessment of why the problem is recurring. Many companies offer quarterly treatment plans that address spiders as part of general pest management.
Keep Your Whole Home in Good Shape
Spider prevention is connected to overall home maintenance — sealing gaps, managing moisture, reducing clutter, and keeping outdoor areas tidy. The same habits that keep spiders out also improve energy efficiency, reduce other pest activity, and make your home more pleasant to live in.
