Few things ruin a quiet evening like a spider scurrying across the wall. The good news is you do not need a cabinet full of harsh chemicals to keep them out — a well-formulated peppermint spray can send them packing while leaving your home smelling fresh and clean. This guide walks you through the seven best options on Amazon right now, breaking down the real differences in scent strength, coverage, and staying power so you can pick the one that actually fits your home and your tolerance for mint.
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 key to choosing the right peppermint spray for spiders is understanding that not all formulas work the same way — the difference between a light deterrent and a long-lasting barrier often depends on the concentration of peppermint oil (the percentage of pure peppermint oil in the bottle) and how often you are willing to reapply.

How To Choose The Best Peppermint Spray For Spiders
Picking the right spray depends on three decisions: how strong you want the scent to be, if you need it to just repel or also kill on contact, and how often you are willing to reapply. Here is what to look for.
Peppermint Oil Concentration
This is the single biggest factor. A higher concentration of pure peppermint oil — like the 4% or 5% you see in some formulas — creates a stronger sensory barrier that spiders want to avoid. Lower concentrations still work but fade faster, meaning you will be spraying more often to keep the same level of protection.
Contact Kill vs. Repellent Only
Most peppermint sprays are repellents, not killers. They work by overwhelming a spider’s sensory receptors (the organs it uses to detect scent, movement, and danger), driving it away rather than killing it on the spot. A few formulas are strong enough to kill on direct contact, which matters if you are dealing with an active infestation rather than just trying to keep spiders from entering.
Family and Pet Safety
Peppermint oil is generally safe around dogs and cats once the spray dries, but it can be irritating to birds, reptiles, and small pocket pets (like hamsters or gerbils). Check the label for specific warnings; “pet safe” on the bottle usually means safe for dogs and cats when used as directed, not a blanket guarantee for every animal in your home.

In‑Depth Reviews
1. Minty Insect & Pest Control Gallon
The one-gallon workhorse for anyone ready to drench their perimeter in pure mint.
The highest peppermint oil concentration in this lineup — 5% — gives you the strongest sensory barrier against spiders, which means it lasts longer between sprays than any lower-percentage formula here. This Minty gallon delivers a plant-based formula made in the USA that is safe for people, plants, and pets when used as directed. The 128 fl oz jug covers massive areas, far more than any 16 oz bottle. One reviewer noted the scent is very potent and helped with both a mouse and spider problem. Another mentioned it works well for mosquitoes in a wooded yard and appreciated the easy spray wand. The trade-off is the fade — the strong peppermint scent that repels pests fades within days, so plan on regular reapplication to maintain the barrier.
The included sprayer is a weak point: buyers report it tends to leak and does not give a consistent stream, so you may want to transfer it to a better bottle. Compared to the BugMD spray below, this Minty gallon gives you more than four times the volume with a higher oil percentage (5% vs 4%), making it the economical choice for ongoing perimeter spraying rather than quick spot treatments.
Heavy hitter, heavy volume: Buy this if you want one huge bottle to refill your own sprayers for months. The added cost is justified by the 5% concentration and the sheer coverage you get.
The catch: The sprayer that comes with it is disappointing — plan to use your own equipment for best results.
Reach for this if: you own a house with a yard and want to mix up a batch for both indoor baseboards and outdoor plants.
Look elsewhere if: you just need a small bottle for a single apartment window or you want a sprayer that works perfectly from the start.
2. BugMD Pet Safe Multi-Insect Killer & Repellent
This one actually kills bugs on contact while filling your home with a fresh mint scent.
Unlike most peppermint sprays that only repel, BugMD disrupts sensory receptors (the bug’s ability to detect danger) hard enough to kill spiders and other insects on direct spray. It uses 4% pure peppermint oil to do this, according to the maker. One buyer mentioned it works great on springtails and loved that it is natural, though they warned the citronella scent is strong and you need to air out the room after spraying. Another called it the best on the market, praising its 2-in-1 killer-and-repellent action but recommending proactive sanitation and sealing cracks for best results.
The bottle is compact at 7.83 x 4.09 x 2.99 inches and weighs 1.21 pounds — that is a 22% smaller package than the Mighty Mint 16 oz, which makes it more space-efficient for storage. However, because it is designed to kill on contact, it works best as a spot treatment for active pest problems rather than a passive barrier spray. One owner reported it is not a solution for active infestations but is very effective as a preventative measure.
Compared to the Mighty Mint above, BugMD wins when you need immediate knockdown of a visible spider or roach. But if you are just trying to prevent spiders from ever entering, the Mighty Mint’s extra-concentrated repellent power might serve you better over the long term.
What stands out
- Kills ants, spiders, and roaches on contact with a plant-based formula.
- Fresh mint scent from peppermint, rosemary, and citronella oils.
- Also works as a rodent deterrent in garages and basements.
What to know
- Strong citronella smell lingers for a bit after spraying — air out the room.
- Some buyers reported an allergic skin reaction to the ingredients.
Best for active problems: Grab this if you already see spiders and want them gone now, not just discouraged.
skip it if: you have sensitive skin or a strong aversion to citronella scent mixing with the peppermint.
3. Mighty Mint Peppermint Oil Insect Repellent Spray (16 oz)
A proven all-rounder that has been keeping spiders out of homes since 2018.
Mighty Mint is among the most established names in this space, and this 16 oz bottle has a long track record of satisfied buyers. It uses an extra-concentrated peppermint oil formula that works as a deterrent for spiders, ants, roaches, and more — without harsh chemicals. The company recommends it for use around dogs, cats, and kids when applied as directed, but notes it is not recommended around birds or exotic pets. The spray has a fresh minty scent that owners mention is strong for about 20-30 minutes after application but fades to a pleasant clean aroma.
At 9.53 x 3.31 x 2.76 inches, this bottle is 22% larger than the BugMD spray, giving you a slightly bigger package for the same weight. One customer observed it keeps spiders out of doorways and baseboards without harsh chemicals, which matters when you have pets in the house. Another called it their go-to natural pest repellent, noting it deters wasps, roaches, and stink bugs from entry points and lasts a long time. The honest catch: a 3-star reviewer said it is only a decent deterrent and will not cure an active infestation, and found it weak against spiders specifically.
Compared to the Ant & Spider Repellent Spray below, this Mighty Mint is a known quantity with years of reviews backing it up, but it costs a bit more per ounce. It also shares the exact same weight (1.21 pounds) as the BugMD, yet comes in a larger box.
Proven and predictable: Ideal for anyone who wants a natural deterrent with a strong community of real-world feedback confirming it works.
One honest concern: A few buyers found it weak against spiders specifically and better suited for ants and roaches.
Pick this if: you want a spray with years of positive reviews and a formula you can trust for general indoor pest prevention.
Consider another if: spiders are your only target and you want a spray that is specifically praised for spider control over other pests.
4. Waspika Peppermint Oil Insect and Spider Repellent Spray
A fresh-smelling extra-strength spray that customers note shows results within days.
This Waspika spray is formulated with natural peppermint essential oil for extra strength bug control. It is designed to be safe around pets and family when used as directed, with no strong fumes or harsh chemicals. The non-staining formula leaves no residue on baseboards, entryways, kitchens, patios, or garages. One user highlighted a significant reduction in spiders and insects within days of using it, and another specifically noted fewer spiders and cobwebs both indoors and outdoors.
Buyers consistently praise the pleasant peppermint scent, describing it as fresh and not chemical-smelling. Multiple reviewers noted it dries quickly and leaves no sticky residue. At 1.26 pounds, it is slightly heavier than the BugMD and Mighty Mint sprays (both at 1.21 pounds), giving you a hint of a denser liquid that might last a touch longer per spray. One shopper added they sprayed doors, windows, and the porch and noticed fewer spiders, and they plan to repurchase.
Compared to the Ant & Spider Repellent Spray below, this Waspika formula is also an extra-strength option but at a slightly higher price bracket. The direct head-to-head: both are 16 oz plant-based sprays, but Waspika weighs 1.26 pounds versus the Ant & Spider spray at 1.41 pounds, making it a bit lighter in the hand.
Why buyers love it
- Significant reduction in spiders and cobwebs reported within just days.
- Fresh peppermint scent with no harsh chemical fumes.
- Dries quickly and leaves no sticky residue behind.
A note
- As a newer product (available February 2026), it has fewer long-term reviews than established brands.
- Like most repellents, it requires reapplication to maintain the barrier.
Great for immediate results: Reach for this if you want a plant-based spray that reviewers point out works quickly to drop your spider count within days.
Not for you if: you prefer a brand with a decade of reviews to back its long-term effectiveness.
5. VANQUAR Peppermint Oil Insect & Spider Repellent Spray
A 16 oz bottle that the maker claims delivers up to 1,500 targeted sprays for extended coverage.
VANQUAR positions this as a long-lasting, extra-concentrated spider repellent infused with high-purity peppermint oil (a refined form of peppermint essential oil) and other natural extracts. The formula is designed to create an uncomfortable environment for spiders and bugs while leaving a fresh, crisp scent that is gentle for scent-sensitive households. Buyers consistently report noticing fewer spiders and insects after applying it around doors, windows, and kitchens. One reviewer called it a great product with natural ingredients, noting it has been safe to use around their dog when used as directed.
At 1.28 pounds, it is the same weight as the Mighty Mint 2-Pack below, but in a single 16 oz bottle. Buyers describe the peppermint scent as fresh and not overpowering, which is a common theme among the reviews. One buyer specifically appreciated that there is no strong chemical smell and that the bottle lasts a long time. The company states it is safe around dogs, cats, and kids when applied as directed, with no harsh fumes.
Compared to the Mighty Mint 16 oz above, this VANQUAR spray is a newer entry (March 2026) with a similar price point but a more focused claim of 1,500 applications per bottle. The Mighty Mint has the advantage of years of review history, while VANQUAR offers a comparable formula at competitive value.
High value per spray: If you want a long-lasting bottle that promises a huge number of applications, this is a strong contender. The reviews back up its effectiveness for general spider and insect deterrence.
The honest trade-off: It is a newer product, so it lacks the deep review history of the Mighty Mint or BugMD. The long-term consistency is less proven.
Ideal for cost-conscious buyers: Pick this if you want a lot of sprays per dollar and the reassurance of a pleasant, natural scent that does not overwhelm your home.
Consider an established brand instead if: you need a spray with a longer track record of verified reviews over multiple years.
6. Ant & Spider Repellent Spray 16 oz
A budget-friendly entry that doubles up with peppermint and cinnamon oils for a broader bug barrier.
This spray uses a blend of peppermint oil and cinnamon oil to stimulate the olfactory and visual systems (scent and sight organs) of ants, spiders, and roaches, deterring them from approaching. It weighs 1.41 pounds versus the BugMD spray at 1.21 pounds, and its package dimensions are 8.43 x 3.74 x 3.11 inches versus BugMD’s 7.83 x 4.09 x 2.99 inches. The formula is plant-based and the company states it is safe for children and pets once dried, with no discomfort in areas where they crawl or play.
Buyers consistently mention the fresh mint scent and the confidence that comes from using a non-toxic spray around their pets and kids. One reviewer specifically said it is super practical for both inside and outside the house to keep spiders and ants at bay. The herbal mint scent is described as pleasant and not too strong. The spray is suitable for kitchens, living rooms, behind appliances, corners, garages, and attics.
Compared to the Mighty Mint 16 oz above, this Ant & Spider spray is a lighter investment per bottle and weighs 1.41 pounds versus 1.21 pounds. The cinnamon oil addition gives it a slightly different scent profile that some may prefer over pure peppermint.
What works
- Dual oil formula (peppermint + cinnamon) targets multiple sensory receptors in pests.
- 1.41-pound bottle with peppermint and cinnamon oils.
- Buyers love the natural mint scent and safety around kids and pets.
Keep in mind
- As a brand-new product (available October 2025), it has no long-term review history.
- One reviewer noted it requires repeated use for longer-lasting results.
Best for budget entry: Grab this if you want to try a peppermint-based spray without spending much and appreciate the added cinnamon oil for a unique scent.
Not for you if: you want a spray with years of proven feedback from hundreds of buyers.
7. Mighty Mint 8oz Spider Repellent Peppermint Oil (2-Pack)
A two-pack of extra-concentrated Mighty Mint that some shoppers say keeps spiders away for a month.
This 2-pack gives you two 8 oz bottles of Mighty Mint’s extra-concentrated spider repellent, using Pure Origin Peppermint Essential Oil as the active ingredient. The smaller 8 oz size is easier to handle for quick sprays around door edges and windowsills. One buyer who is terrified of spiders called this the best spider repellent they have tried, reporting it keeps spiders away for at least a month without killing them. Another reviewer noted it works quickly with a pleasant peppermint scent and no annoying spray smell.
The catch is that application technique matters. One buyer found spiders returned quickly initially, but after learning to spray heavily around door edges, the repellent effect became reliable. Another reviewer with asthma found the smell extremely strong and struggled with it, but still planned to use it on the outside of their house. At 1.28 pounds for the two-pack, it weighs the same as the single VANQUAR 16 oz bottle, so you are getting two bottles for the same shipping weight.
Compared to the single Mighty Mint 16 oz above, this 2-pack offers the same trusted formula in smaller, more portable bottles. It costs more upfront but gives you the flexibility to keep one bottle on each floor or in different rooms without carrying a big sprayer around.
Repellent specialist: This is purely a deterrent — it does not kill spiders. But buyers confirm that heavy, consistent application creates a long-lasting barrier that genuinely keeps spiders out.
The honest limit: The strong peppermint smell can be overwhelming for some people, especially those with asthma or scent sensitivity. Plan to ventilate well after spraying.
Pick this if: you want a proven repellent in a convenient two-pack format and are willing to apply it generously around every entry point for a month-long effect.
pass on it if: you need a spray that kills spiders on contact or you are sensitive to strong peppermint odors.
Understanding the Specs
Peppermint Oil Percentage
This is the number that tells you how potent the spray really is. Higher percentages, like the 5% in the Minty gallon or the 4% in the BugMD spray, create a stronger sensory overload for spiders — meaning they will avoid the area longer because the scent is more intense. Lower concentrations require more frequent reapplication because the scent fades faster. Always check the label for the actual percentage rather than relying on “extra strength” claims alone — the number is the truth.
Repellent vs. Contact Kill
Not all peppermint sprays work the same way. Most are repellents that create an invisible barrier spiders will not cross. A few, like the BugMD spray, are formulated strong enough to kill on direct contact by disrupting the insect’s sensory receptors (the organs it uses to detect danger and scent). If you have an active infestation of visible spiders, you want a contact-kill formula. If you are just trying to keep them from entering, a standard repellent is all you need and it is usually gentler on your home’s surfaces and air quality.
