A spider scurrying across the baseboard can ruin an evening. You want it gone immediately, but without fumigating your kitchen or risking your dog’s health. The right spray kills on contact and leaves a residual barrier that keeps working for weeks, without turning your home into a hazard zone.

Here’s how to pick a spider deterrent spray that actually clears your space, from fast-acting aerosol killers to plant-based barrier sprays.
Our Picks at a Glance
How To Choose The Best Spider Deterrent Spray
Spiders crawl in through gaps, cracks, and open doors. A deterrent spray works in one of two ways: it poisons them on contact, or it lays down a scent barrier they refuse to cross. Choosing between a contact killer and a residual barrier is the first step to a spider-free home.
Decide: Kill now or repel long-term
If you have an active invasion, you want a fast-acting contact killer — an aerosol that drops a spider in seconds. If you want to stop them from ever entering, you want a residual barrier spray that stays effective on surfaces for weeks or even months. Many buyers keep both a contact killer and a residual spray on hand.
Check the spray reach and pattern
Spiders love ceiling corners and the tops of door frames. A spray with a long, targeted stream — some reach up to 5 feet or more — lets you hit them from the floor without a ladder. A wide fog pattern is better for coating large surfaces like baseboards and garage walls.
Match the formula to your household
Chemical sprays are potent but can have strong fumes. Plant-based peppermint oil formulas are gentler — a fit if you have pets, kids, or sensitive noses — but they often need reapplication every few days and may only repel rather than kill. Read the label for the active ingredients before you buy.

In-Depth Reviews
1. Hot Shot Spider & Scorpion Killer Aerosol Spray, 16 Oz, 3 Pack
Our pick — over 4.5★ from 250+ verified ratings; the strongest balance of quality and price.
The aerosol that ends spider standoffs in seconds and keeps working for months
This is the spray you grab when a black widow is in the garage and you want it gone before you blink. The fast-acting formula kills spiders, scorpions, and other listed insects in seconds, and it specifically targets black widow spiders as they hatch. That instant-kill reputation is the thing buyers rave about most, with the basement crowd reporting spiders finally under control.
The residual effect is what separates it from a one-shot spray. It keeps killing ants (excluding harvester, pharaoh, and fire ants), cockroaches, and crickets for up to 4 months after you apply it, so one pass around the baseboards buys you a whole season of quiet. The water-based formula is non-staining and leaves no oily residue or lingering odor, which matters when you are spraying near stored boxes.
The broad spray pattern reaches up to 5 feet, letting you cover a full wall of garage rafters without moving the ladder. Buyers report the 8-ft reach in practice makes hitting high ceiling corners easy, and long-time users say it simply works — the kind of product people repurchase year after year.
What wins people over
- Kills spiders and scorpions in seconds — no waiting
- Residual killing power lasts up to 4 months
- Broad up to 5-ft spray covers large areas fast
- Water-based and non-staining with no lingering odor
Before you buy
- Aerosol cans are bulkier than a simple squeeze bottle
- Chemical formula is not the right fit for scent-sensitive homes
Reach for it if: you need instant kills plus months of protection in basements, garages, and anywhere spiders hide.
Look elsewhere if: you want a purely natural, plant-based approach for every room in the house.
2. Mighty Mint Peppermint Oil Insect Repellent Spray, 16 oz
A minty, pet-safe barrier that sends spiders packing without harsh chemicals
For households with curious dogs and cats, this is the spray that fits the way you actually live. It is formulated with extra-concentrated peppermint oil to deter spiders, ants, and roaches, and it is designed to be safe around dogs, cats, and kids when used as directed. Owners mention using it on baseboards, entryways, and patios without worrying about staining surfaces.
The fresh, synthetic-free mint scent lingers cleanly without a chemical smell. It also works beyond the bug world: owners mention spraying it on flowerbeds keeps deer from eating flowers and shrubs, because they do not like the smell. This dual-purpose deterrent suits both gardeners and homeowners.
Know the trade-off: this is primarily a contact spray, so it repels and kills only on a direct stream hit. At 1.23 pounds, the bottle is a touch heavier than some rivals like the Nature-Cide at 1.1 pounds, but the weight difference is negligible in daily use. Wipe any residue to avoid stickiness on surfaces.
The upside
- Pet-friendly and family-safe peppermint formula
- Pleasant mint scent with no synthetic fragrances
- Versatile — deters deer from flowerbeds too
- Ready-to-use 16 oz spray for quick treatments
The catch
- Mostly repels — reliable kills need a direct stream hit
- Sprayer performance draws mixed feedback
- Not a long-term residual barrier against a full colony
A strong fit for: pet owners who want gentle, plant-based protection in kitchens and high-traffic rooms.
Think twice if: you need heavy-duty contact-killing power against an active infestation.
3. BugMD Pet Safe Multi-Insect Killer and Repellent Spray
A plant-powered spray that kills spiders on contact and keeps mice away as a bonus
This one does double duty in a way most sprays cannot match. The formula uses essential oils like peppermint, rosemary, and citronella to kill ants, spiders, and roaches on contact, and the concentrated peppermint scent also acts as a rodent deterrent. Customers note it cleared spiders hiding in the stucco of their house, and the application is simple on baseboards, windowsills, and in kitchens.
The fresh mint scent is a recurring point of praise — it smells far more pleasant than harsh chemical sprays, which is why people use it between professional pest control treatments. One owner in Texas, where “every insect ever found” lives, keeps it in rotation for ongoing defense. It is formulated for use around children and pets when used as directed.
Plan to reapply every three to five days to maintain the repellent barrier, since this is not a months-long residual. The essential oil base can leave a slight oily look right after spraying, though reviewers point out it dissipates quickly. It’s a ready-to-use alternative to slow-acting baits, but it requires reapplication every few days.
Why it stands out
- Kills and repels spiders, ants, and roaches on contact
- Peppermint scent doubles as a mouse and rodent deterrent
- Plant-powered formula safe around kids and pets
- Pleasant fresh mint smell, not chemical
Keep in mind
- Needs reapplication every 3 to 5 days for a full barrier
- Leaves a slight oily look that fades quickly
- Some buyers find the scent too strong
The right pick for: anyone wanting one natural spray that handles spiders plus a few stray mice in the garage or basement.
Not for: those who want a single application to last for months.
4. Nature-Cide All Purpose Insecticide, 32 oz
A plant-based spray that kills on contact with barely a scent left behind
If strong smells are your pet peeve, this is the formula to try. Made from 100% natural and non-toxic ingredients with the active ingredient glycerin, it kills bedbugs, cockroaches, ants, wasps, and other pests on contact. Shoppers say it “works great for spiders” and appreciate that there is no real odor hanging in the air afterward.
At 32 fluid ounces, this bottle delivers twice the liquid of a standard 16-ounce spray, which matters when you are treating more than one room. It is a ready-to-use solution in a commercial spray bottle, so there is no mixing or measuring. The safety angle is a big draw — one owner uses it all over without fear of poisoning their dogs.
The honest limitation here is that effectiveness gets mixed reviews as a contact killer — it works reliably for spiders and ants, but some buyers found it underwhelming on large cockroaches. The scent-free quality is what most people praise along with the safety. It is a solid all-natural option for everyday spider and ant duty.
What owners liked
- Nearly scent-free — no chemical smell after spraying
- 32 oz of ready-to-use liquid in one bottle
- 100% natural ingredients, gentle for homes with pets
- Works well for spiders and ants on contact
What to expect
- Contact-only — no residual barrier for long-term control
- Effectiveness on larger roaches is inconsistent
- Mixed feedback on the sprayer’s performance
Choose this if: you want natural, low-odor contact killing and a bigger bottle for wider coverage.
skip it if: you are counting on one spray to create a lasting perimeter barrier.
5. Harris Spider Killer Liquid Spray, 32oz 2-Pack
An odorless, EPA-registered spray that kills spiders as it dries and keeps them away for weeks
If you hate the smell of bug killers, this barrier spray is for you. The odorless, non-staining formula kills spiders once completely dried, and it also handles ants, roaches, Asian lady beetles, crickets, and silverfish. It is registered with the Environmental Protection Agency (No. 3-11) for indoor residential use, so you get a stamp of legitimacy for indoor confidence.
Buyers in heavily wooded areas swear by it — one lives in the woods with infrared security cameras and found this spray far more effective than the leading brand at keeping webs off the lenses. The spray stream stays composed, making it easy to hit spiders up to 6 feet away on roof rafters. It works for about three to four weeks per application, and does not stain walls or concrete.
At 64 fluid ounces total across the two-pack, it is a generous supply for the money, and the odorless quality means you can use it indoors and outdoors without airing the house out. The main gripe is the spray mechanism — occasional nozzles do not spray properly. The spider killing is what owners praise most, with many calling it the best they have used in decades.
The strengths
- Odorless and non-staining on fabrics and walls
- EPA registered for indoor residential use
- Kills spiders when dry; works 3-4 weeks per spray
- Two-bottle pack gives you 64 fluid ounces total
The drawbacks
- Nozzle quality is inconsistent across bottles
- Some buyers feel the value is a waste of money
Best if: you want a serious, odorless chemical barrier for indoor perimeter defense that lasts weeks.
Not ideal if: a faulty spray nozzle would be a dealbreaker for you — check it right away.
6. Peppermint Oil Insect and Spider Repellent Spray, 16 oz
An extra-strength peppermint spray that builds a plant-powered barrier without sticky residue
This spray turns the classic peppermint trick up a notch. Formulated with natural peppermint oil for extra strength, it is designed to repel and control spiders, ants, and roaches while staying safe around pets and family when used as directed. Owners consistently report a significant reduction in spiders after spraying around doors, windows, and corners.
The quick-drying, non-staining formula is a practical win — it leaves no residue and no sticky feeling, so you can spray baseboards in the kitchen without worrying about your socks. The crisp peppermint scent freshens the room rather than assaulting it, which buyers routinely describe as pleasant and non-overpowering compared to chemical sprays.
The 16 oz bottle is easy to handle for regular use indoors and outdoors, from entryways to patios to garages. It works well as a routine preventive treatment rather than a one-time fix, and buyers report it is worth the money for the safety and scent alone.
What stands out
- Extra-strength peppermint for sturdy natural defense
- Dries fast with no sticky residue
- Pleasant mint scent that freshens rooms
- Safe for pets and kids when used as directed
Consider this
- Repels more than it kills — direct hits do the killing
- 16 oz goes fast with frequent reapplication
Reach for this if: you want a strong natural spray as a weekly routine in high-traffic rooms.
Pass on it if: you are dealing with an active infestation that needs instant chemical knockdown.
7. Ortho Home Defense MAX Insect Killer Spray, 24-Ounce 2-Pack
The set-and-forget perimeter spray that protects your home for up to a year
This is the long-haul champion of the list. Ortho’s Home Defense MAX controls ants, roaches, and spiders indoors on nonporous surfaces for up to 12 months, creating a bug barrier that most other sprays cannot touch. One owner sprayed an area, let it dry, put everything back, and did not see a single ant for almost a month — with the promise of a full year of control.
The formula is odor-free and non-staining, so it is comfortable to use around windows, doors, screens, and the bottom of doorways. Long-term users keep a bottle in the basement, garage, and upstairs for quick touch-ups, and describe it as very effective for household perimeter defense. The 24-ounce two-pack gives you plenty to cover an entire home perimeter.
The honest trade-off: it is not the fastest knockdown. Owners mention that a directly sprayed roach may keep crawling for a while before dying, which is a different experience from instant-kill aerosols. But for prevention and long-lasting control, this is the one that keeps bugs from ever getting a foothold.
The big wins
- Controls spiders, ants, and roaches up to 12 months
- Odor-free and non-staining indoors
- Creates a lasting bug barrier around the perimeter
- Two 24-oz bottles cover a whole home
The trade-offs
- Slower kill — sprayed bugs may keep moving for a bit
- Opinions on value are mixed among buyers
Pick this for: homeowners who want to spray once and forget about bugs for nearly a year.
Look elsewhere if: you need instant, visible kills on every single bug you hit.
8. Smart Grower Peppermint Oil Spray for Rodents & Insects, 16 oz
One ready-to-use peppermint spray that chases spiders, ants, and even mice out of the house
This is the multi-tasker of natural pest control. The concentrated peppermint essential oil formula repels mice, rats, and rodents on contact while also working on spiders, ants, wasps, bees, and roaches. Customers note a laundry room spider problem resolved after using it, and one boat owner credits it with keeping mice away from their bass boat — a double win most sprays cannot deliver.
The extra-strength, ready-to-use formula needs no mixing and claims fewer applications for longer-lasting control. It is safe to use around the family in kitchens, bedrooms, and basements with 100% pure peppermint oil and no synthetic pesticides. Owners emphasize the peppermint scent is far more livable than a harsh chemical spray.
Two practical notes: the spray nozzle must be secured properly, and the bottle can warp in heat and cause spills, so store it cool. The strength is solid for spiders after several uses, though it may not tackle heavy mosquito pressure outdoors.
What it does well
- Repels rodents as well as spiders, ants, and wasps
- Ready-to-use with no mixing required
- 100% pure peppermint oil, no synthetic pesticides
- Works indoors and outdoors in many spaces
Watch out for
- Nozzle must be secured properly to prevent leaks
- Bottle can warp in heat and spill
- Strength is mixed — some find it not strong enough
Choose it if: you want one natural spray that doubles as a spider spray and a rodent repellent.
pass on it if: you expect it to nuke a heavy outdoor pest population.
9. Wondercide Indoor Pest Control Spray, Peppermint 16 oz
A plant-powered spray that kills a huge range of pests and is gentle enough for weekly use
For homes where pets rule, Wondercide is the spray to keep. It uses natural essential oils — 4.2% cedar oil, 2.2% sodium lauryl sulfate, 1.5% peppermint oil, and 0.1% sesame oil — to kill and repel ants, roaches, spiders, flies, fleas, ticks, wasps, and mosquitoes. The brand designs it to be safe around dogs and cats when used as directed, and owners praise that as the reason they keep it in the house.
It goes beyond spiders into full flea control: the spray kills fleas in carpet, furniture, bedding, and flooring, eliminating adults, eggs, and larvae without staining. Reviewers point out it kills crickets, spiders, roaches, and centipedes, and works on direct contact for insects like spotted lantern flies. The scent is plant-based with no artificial fragrances.
Be realistic about the catch: the residual effect is weak, so this needs frequent reapplication to keep working — one owner found a bottle lasts about a month with regular use. It is a pricey option for heavy infestations. The kill can also take one to two minutes rather than being instant.
Why it wins fans
- Kills and repels a huge range of indoor pests
- Doubles as a flea treatment for carpet and furniture
- Plant-powered with no artificial colors or fragrances
- Safe around dogs and cats when used as directed
Be honest about
- Weak residual effect — needs frequent reapplication
- Slower kill, taking 1-2 minutes on some bugs
- Oil-based spray can leave residue on walls and carpets
- Pricey for a smaller 16 oz bottle
Reach for it if: you want a family-safe spray that also handles fleas in your carpets and pet bedding.
Look elsewhere if: you need a budget-friendly option with months of residual power.
Understanding the Specs
Residual Effect vs. Contact Kill
This is the single most important spec to understand. Contact killers drop a spider the second the spray hits it, but they leave no lasting protection. Residual sprays leave a barrier on surfaces that continues killing for weeks or months — like the Ortho formula that controls pests up to 12 months or the Hot Shot that keeps killing for up to 4 months. If you want prevention, you want residual power.
Spray Reach and Pattern
Spiders live up high, in ceiling corners and on door frames, so a spray’s reach decides if you need a ladder. The Hot Shot aerosol delivers a broad pattern up to 5 feet, while buyers of the Harris spray report a composed stream that easily hits spiders 6 feet away. A wide fog pattern coats large surfaces fast, but a targeted stream is better for picking off individual spiders.
