You want the spiders gone, but the idea of spraying poison around your dog or cat feels worse than the eight-legged intruder itself. A genuinely pet-safe spider spray lets you keep your home spider-free without risking your pet’s health. This guide sorts through the natural, plant-based options that actually keep spiders away without the harsh chemical fumes.
I’m Rikta — the founder and writer behind Lawn Gear Lab. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
The best pet safe spider spray for your home depends on where you need protection and how often you can reapply. We break down nine top contenders to help you choose.
Our Picks at a Glance
How To Choose The Best Pet Safe Spider Spray
Not all natural sprays work the same way. Some kill insects on contact, while others just create a scent barrier that spiders avoid. Knowing which action you need is the first step to picking the right bottle.
Match the Spray to Your Pest Problem
If you are dealing with an active spider problem and want immediate results, you need a spray that kills on contact. If you are trying to prevent spiders from entering in the first place, a repellent barrier around doors and windows is the better bet. Many sprays do both, but they excel at one or the other.
Check the Active Ingredients
Peppermint oil is the most common natural active ingredient because spiders dislike the strong scent. Some formulas add other oils like rosemary, citronella, or cedarwood for a broader pest range. The concentration of these oils determines both the smell strength and how long the protection lasts.
Consider Application and Coverage
For quick spot treatments inside your home, a ready-to-use spray bottle is the easiest to grab and go. If you need to cover a large yard, a hose-end attachment that treats up to 5,000 square feet works better. Decide first whether you’ll spray baseboards, patios, or both—that choice determines which tool you need.

In‑Depth Reviews
1. Peppermint Oil Insect & Spider Repellent Spray
Our pick — over 4.5★ from 250+ verified ratings; the strongest balance of quality and price.
The fresh-scented all-rounder that keeps the whole house spider-free without harsh fumes.
This is the pick that solves the biggest worry most pet owners have: finding a spray that is genuinely safe around dogs, cats, and kids while still doing the job. The formula uses high-purity peppermint oil and natural plant extracts to create a barrier that spiders actively avoid, and it is explicitly labeled safe for use around pets and children when applied as directed.
What wins people over here is the scent. The fresh, minty smell is the most-praised feature by a wide margin, and it is a welcome change from the chemical odor of traditional sprays. It is also a versatile performer, designed for kitchens, bathrooms, garages, gardens, patios, and even vehicles, with a formula that won’t stain surfaces. A single 16 oz bottle delivers up to 1,500 targeted sprays, stretching your dollar.
Owners consistently report seeing fewer spiders around doors and windows after a quick application, and the spray is noted for its easy, even coverage with no sticky residue left behind. The 1.28-pound bottle is light enough to carry from room to room or out to the garden without a second thought. It is a contact repellant rather than a killer, so it works best as a proactive barrier.
Why it wins
- Pleasant peppermint scent that owners praise most
- Safe for pets, kids, and scent-sensitive households
- Versatile — works indoors, outdoors, and in vehicles
- Light 1.28-pound bottle with up to 1,500 applications
The trade-offs
- Repels spiders but does not kill them on contact
- Needs reapplication to maintain the barrier
Reach for this if: you want a family-safe, pleasant-smelling daily barrier around your home’s entry points.
Look elsewhere if: you need to kill an active infestation on contact rather than prevent one.
2. STAR BRITE Spider Away
The marina-ready repellent that chases spiders off docks and boats without harming them.
This one is built for the outdoor spaces where spiders love to hide: garages, porches, docks, boathouses, sheds, and gazebos. The planet-friendly, biodegradable formula works by making the area unappealing so spiders leave on their own, rather than killing them. It is safe for use around people, pets, and wildlife when used as directed, and it works on multiple surfaces including plastic, metal, vinyl, wood, glass, and painted surfaces.
The full 22 fl oz can is a big reason to consider it, giving you more coverage per bottle than the standard 16 oz sprays. However, there is a critical trick to getting it to work: buyers report that you must shake it vigorously before each use. Those who skip this step see poor results initially. Those who do shake it report spider-free balconies and doorways for a full week.
It is noticeably heavier than many competitors at 1.7 pounds, which reflects the larger aerosol can. Keep in mind that some spiders may still appear in treated areas at first, but they should leave within a few days. As an unscented option, it is a smart choice if you want to avoid adding any fragrance to your outdoor living spaces.
Its strengths
- Large 22 fl oz can for extended coverage
- Biodegradable and safe for pets and wildlife
- Works on a wide range of outdoor surfaces
Know before you buy
- Must be shaken vigorously before each use to work
- Some owners find results inconsistent on boats
Choose it for: docks, boats, and patios where a larger, unscented repellent barrier is needed.
Think twice if: you expect a set-and-forget solution without the shake-first ritual.
3. BugMD Pet Safe Multi-Insect Killer and Repellent Spray
The dual-action spray that kills on contact today and keeps repelling for days after.
This is the one to grab when you want immediate action against active pests, not just a preventive barrier. The all-in-one formula kills ants, spiders, and roaches on contact, while the essential oil blend of peppermint, rosemary, and citronella leaves a fresh mint scent that keeps new pests away. It is formulated for use around children and pets when used as directed.
It is a multi-purpose household defender, suitable for non-porous surfaces like baseboards, windowsills, and kitchens. The manufacturer recommends reapplying every three to five days to maintain the repellent barrier, which gives you a clear maintenance schedule. A nice bonus is the concentrated peppermint scent, which also acts as a deterrent for mice and other rodents in garages and basements.
Buyers who have tried other pest control methods say this is one of the best they’ve used, praising its natural ingredients and the confidence of using it around kids and pets. The 1.21-pound bottle is light enough to carry from room to room. It feels balanced—not as flimsy as the lightest sprays, not as bulky as heavier aerosol cans.
Solid all-rounder: combines contact kill with a lasting repellent barrier in one 16 fl oz bottle, and the rodent-deterrent bonus adds real value for garages and basements.
4. Nature’s Dome Pest Control Spray
The triple-oil knockout punch for anyone fighting more than just spiders.
If your pest problem goes beyond eight-legged intruders, this spray is designed to handle a wider roster. It kills 40+ pests on contact, including ants, roaches, spiders, mosquitoes, ticks, fleas, flies, and bed bugs. The fast-acting formula works against both adult insects and their larvae, which helps break the pest life cycle.
The secret is the triple-action blend of geraniol, cinnamon oil, and cottonseed oil. Each one attacks pests differently — geraniol disrupts their nervous systems, cinnamon oil repels, and cottonseed oil suffocates on contact. This is a more sophisticated approach than single-ingredient sprays. Lab-tested and certified safe for dogs, cats, children, and plants when used as directed.
This EPA-listed formula has a mild natural scent, and the 16 oz bottle covers up to 500 sq ft. Owners note it kills fire ants effectively and is safe enough to use around cats, with one even mentioning their vet approved it. The recommended reapply window is every 5-7 days, which is a little more forgiving than some other sprays.
The upside
- Kills 40+ pests, including larvae
- EPA-listed and lab-tested pet & family safe
- Covers up to 500 sq ft per 16 oz bottle
The caveats
- Strong scent can spread through the house for some
- May require multiple applications for stubborn ants
Best if: you need one spray that tackles a whole list of household pests, not just spiders.
Not ideal if: you are highly sensitive to strong natural scents.
5. Mighty Mint Peppermint Oil Insect Repellent Spray
The extra-concentrated spray that kills fast and smells like a candy shop.
This is the spray with serious name recognition, and it has the review volume to back it up — a huge community of owners has put it to the test. The formula uses extra-concentrated peppermint oil, making it a proven deterrent and killer for spiders, ants, and roaches. It is safe to use around dogs, cats, and kids when applied as directed, with no harsh fumes.
The scent is the defining feature here. Owners describe it as a pleasant, crisp mint — some even compare it to chocolate mint — that lingers without overwhelming the room. It is also free from synthetic fragrances, making it a gentle option for scent-sensitive households. A nice bonus is the included microfiber cloth, which helps with clean-up after application.
It is a contact spray, meaning it works best when you spray the pest directly rather than just laying down a barrier. Owners mention fast kills on spiders and sugar ants, though some note that ants can return once the spray dries, since it doesn’t eliminate the whole colony. The 16 oz bottle is ready to use right from the start — just spray and go.
Fast and fragrant: the best-smelling option here by owner consensus, with quick contact kills, but it is a spot-treatment tool rather than a colony eliminator.
6. Smart Grower Peppermint Insect & Pest Control Spray
The pure-oil barrier that tackles everything from spiders to mice to rats.
This spray is for the homeowner dealing with a diverse cast of unwelcome visitors. Beyond spiders, ants, wasps, and bees, the formula is powerful enough to repel mice and rats. It uses 100% pure peppermint essential oil with no synthetic pesticides, creating a long-lasting barrier that keeps pests out of your home, garden, and outdoor spaces.
The extra-strength formula is ready to use straight from the bottle with no mixing required. It is designed for year-round protection across home, apartment, garden, shed, attic, basement, garage, and vehicle. For a versatile pest solution, this covers more ground than most. The label directs you to check pet safety information before use.
Owners have had notable success with this one specifically for rodents — a bass boat owner reports it keeps mice away, and another user drenched their awning to successfully drive off bats. The scent is described as nice and not overpowering. One owner found it effective as a deterrent for ants, though they noted you have to keep up with reapplication since it doesn’t kill them.
Beyond spiders: the rare natural spray that earns real praise for repelling mice and rats, making it a strong fit for garages, boats, and attics where rodents are the real issue.
7. Wondercide Ant & Roach Aerosol Spray
The aerosol that drops a thousand ants in under a minute.
When you need instant results, the aerosol format gives you a longer reach and a more powerful spray than a standard pump bottle. This is designed for quick kill and fast knockdown of ants and roaches, proven to work against over 20 common household bugs including spiders, fleas, carpet beetles, earwigs, silverfish, and stink bugs. It’s a lab-proven, plant-powered alternative to chemical sprays.
The formula uses natural essential oils of lemongrass and geraniol, with no artificial colors or fragrances, and is formulated to be safe around pets and family when used as directed. It is easy to use throughout the home: point, spray to kill the bug, and wipe them away. The 2-pack gives you two 10 oz cans, which is handy for keeping one in the kitchen and one in the garage.
Effectiveness is the most-praised feature by far — customers note killing large numbers of ants almost instantly and eliminating roach nests on contact. One buyer called it “the best product ever purchased” after watching ants drop in under a minute. The main trade-off mentioned is an oily residue left behind, which owners note is part of what stops the bugs.
What stands out
- Fast, powerful knockdown of ants and roaches
- Kills over 20 different household bugs
- 2-pack value for multi-room coverage
Watch for
- Leaves an oily residue after spraying
- Scent is strong for some owners
Grab this if: you want a powerful aerosol with a long reach for active infestations in kitchens and baseboards.
skip it if: you dislike wiping up an oily film after spraying.
8. Trail Guard Natural Extra Strength Spray
The one-bottle solution for fleas, ticks, and spiders on every family adventure.
This is a different kind of pet-safe spray because it is designed to be used directly on your pets as well as around your home. It is safe for use on dogs, cats, and humans, from young kittens to senior dogs, and gentle enough for children. The formula kills 98-100% of fleas, ticks, and other pests on contact while leaving a repellent barrier against new ones.
The active ingredients are cedarwood oil, plant-based sodium lauryl sulfate, lemongrass oil, and sesame oil. The manufacturer says this formula packs 3X the active ingredients of comparable natural sprays. It is made in the USA and free from artificial dyes, colors, and fragrances. The pleasant lemongrass scent is a big part of the appeal, making it a fresh alternative to chemical-heavy collars and drops.
It is designed for outdoor enthusiasts, protecting you, your kids, your dog, and all your gear on adventures. Owners have taken it camping and report effective protection in wooded areas, along with reduced fleas around the home. The main gripe is the spray bottle itself, with some owners reporting the sprayer stops working after a couple of weeks of use.
Why it’s different
- Safe to spray directly on dogs, cats, and people
- 3X the active ingredients of similar natural sprays
- Pleasant lemongrass scent, made in the USA
The catch
- Spray bottle can fail after a couple weeks for some
- Strong scent requires care to avoid overspray
Perfect for: campers and hikers who want one natural spray for the whole family — pets included.
Consider alternatives if: you only need a home barrier and don’t want to spray directly on your pet.
9. Cedarcide YardSafe
The hose-end heavyweight that treats the whole yard, not just the baseboards.
This is the pick for the bigger picture: the backyard where kids and dogs play. It is a yard treatment rather than a spot spray, designed to be attached to your garden hose and sprayed over large areas. The 1-quart (32 oz) bottle treats up to 5,000 square feet, making it a true whole-property solution for mosquitoes, ticks, fleas, chiggers, and more.
The formula uses natural essential oils — specifically a powerful cedar and lemongrass blend — for a toxin-free solution. The brand backs it with over 20 years of testing and a 100% satisfaction guarantee. It is pet-friendly and family-safe, so you can treat the yard without worrying about the dogs rolling in the grass afterward.
Reviewers point out impressive results, with one saying ticks are completely gone after other methods failed, and another solving a chigger problem while keeping two Boston Terriers safe after a 2-hour dry time. The scent gets solid praise. The effect lasts through normal rain but may need reapplication after heavy downpours. Since it’s a repellent, effectiveness is mixed for some, particularly against mosquitoes.
The big win
- Treats up to 5,000 sq ft via hose attachment
- Natural cedar and lemongrass formula
- Survives normal rain; pets safe after dry time
Keep in mind
- Effectiveness is mixed for mosquitoes specifically
- Not a spot-treatment tool for indoor use
Choose this for: reclaiming a large yard from ticks, chiggers, and mosquitoes while keeping pets and kids safe.
It’s not for: indoor baseboard treatments — that’s a job for a pump spray.
Understanding the Specs
Kill vs. Repel
This is the most important distinction. A contact killer like Wondercide or Nature’s Dome kills pests on contact and is best for active infestations. A repellent like the Peppermint Oil Repellent spray creates a scent barrier that keeps spiders away but doesn’t eliminate existing ones. Some sprays like BugMD and Mighty Mint do both. Decide whether you’re treating an existing problem or preventing a future one.
Active Ingredients
Peppermint oil is the most common natural active ingredient because spiders and many insects strongly dislike the scent. Other effective oils include rosemary, citronella, lemongrass, cedarwood, geraniol, and cinnamon. The more concentrated the oil, the stronger the scent and the longer the protection tends to last. For scent-sensitive households, look for formulas without synthetic fragrances.
