With Nature’s MACE 40 oz Squirrel and Chipmunk Repellent Spray, those pesky invaders meet a gentle but firm “not here.” This plant-based, humane spray doesn’t just keep squirrels and chipmunks away, it helps you reclaim your garden, your peace of mind, and even your engine bay.

Product Description

What This Spray Is and Who It Is For

This product, Nature’s MACE 40 oz Squirrel and Chipmunk Repellent Spray, is a plant-based, ready-to-use formula crafted to deter animals like squirrels, chipmunks, raccoons, and even the occasional rabbit or skunk. It is not a poison or trap; rather, it is a non-toxic, humane option designed for people like you who want wildlife out of your space without harming them. Whether it is your garden, attic, vehicle, or bird feeders, this spray is meant to protect without polluting.

How It Works

I like to explain it this way: imagine squirrely intruders approaching your prized azaleas or engine wiring. What hits them first? The sharp, spicy aroma. This formula combines peppermint, cinnamon, garlic, castor, and soybean oils, each adding scent or taste deterrence. Crucially, there is also a special sticking agent that helps the spray cling even after rain, a big step beyond homemade mixes that wash away instantly. Over time, the squirrels or chipmunks start associating your yard with an unpleasant experience, guiding them elsewhere.

What Makes It Tick and Sets It Apart

• Plant-Based, Non-Toxic Ingredients: Each component is something you would find in a spice rack, not a chemical lab. Made with essential oils and eco-friendly carriers, it is safe for kids, pets, and beneficial wildlife when used as directed.
• Sticking Agent for Durability: It is not just strong, it is long-lasting. That cling factor means protection sticks through light weather, unlike one-off DIY sprays.
• Multi-Purpose Use: You can spray a tree trunk, your engine bay wiring, or the poles of bird feeders. That flexibility makes it more valuable in real-life scenarios, especially once you have had to rewire a car after a squirrel’s midnight snack.

How to Use Nature’s MACE Squirrel Repellent 40 oz Spray

You do not need fancy gear to put this repellent to work. What you do need is a patient “training week,” dry surfaces, and a simple routine. Below is the exact process I give clients, with manufacturer directions and field-tested tips folded in.

Before you start: quick prep and safety

Give the bottle a vigorous shake. Start with dry surfaces and calm weather. Nature’s MACE instructs you to spray daily for the first seven days, then shift to weekly maintenance, and to reapply after a heavy rain. That first week matters a lot because you are breaking a habit.

If you are treating delicate ornamentals, do a small test patch first. The label guidance also advises against heavy spraying on soft-bodied plants. If you need to protect tender plants, treat the pot or surrounding soil instead of the foliage.

Repellents in general work best when you keep up with reapplications, especially after storms. University extension guidance echoes this, noting most repellents need periodic refreshes and touch-ups following heavy rain.

Step-by-step for gardens, beds, trees and bulbs

On day one, walk the property and spray the places squirrels actually touch and travel. That usually means the base of tree trunks, fence tops, railing edges, deck joists, planter rims, and the perimeter around beds. During the training week, spray those same travel lines and chew points once per day, then shift to once a week for maintenance. If activity spikes, add a mid-week touch-up.

Planting bulbs? You can mist bulbs lightly, let them sit for about fifteen minutes to dry, then replant. I still protect the bed with a light perimeter spray and some hardware cloth until plants are up, since physical barriers plus repellents are more reliable than either alone.

Bird feeders and poles

To guard feeders, treat the surfaces squirrels grip the most, like poles, perches, hanger arms, and the branch where the feeder hangs. The brand’s own FAQ calls this out and also suggests using hot pepper in seed as a companion tactic. Birds cannot sense capsaicin the way mammals do, which is why this combination can help you hold ground at the feeder.

Research on capsaicin-treated seed at feeders has shown it can cut squirrel feeding time while birds keep visiting. If you try peppered seed, wear gloves, and still keep up a weekly spray on the hardware since repellent films weather over time.

Attics, sheds and structures

Nature’s MACE says the spray is not for general indoor use, yet it can be applied in barns and attics when you are targeting entry points and trails. In practice, I pair short-term scent deterrence with long-term exclusion: treat around the gap, then seal the hole once you are sure animals are out. Use quarter to half-inch hardware cloth or metal flashing over vents, soffits, and louver screens.

University and trade guidance is consistent here. Exclusion is the durable fix. Fasten hardware cloth over openings with screws or staples, overlap the mesh beyond the hole so chewing around the patch is harder, and trim back branches that give easy roof access. Repellents are a training and buy-time tool while you close the building.

Vehicles and outdoor wiring

For vehicle protection, start with a clean slate. The brand’s directions recommend removing nesting material, blowing out food caches with compressed air, and washing signs of rodents with soap and water before spraying. Once clean and dry, treat reachable wiring looms, wheel wells, and under-hood cavities, and lay a light perimeter around the parking spot. Do not spray painted body panels. Reapply during the training week, then weekly.

Independent guidance for cars lines up with the need for routine refreshes. Experts note scent-based deterrents can help but must be reapplied regularly. Combine that with sanitation, parking lights on when possible, and sealing access to reduce repeat visits.

Weather, drying and timing

Apply to dry surfaces and give the repellent time to set. Avoid spraying right before irrigation or a storm, and repeat after heavy rain. That rule of thumb comes from both the label guidance and university extension reminders about weathering and habituation.

How much to use and how often

A 40 oz ready-to-use bottle is rated to cover up to about 1,400 square feet, which is plenty for the typical set of travel lines, trunks, and feeder hardware in a small yard. You will use more during the first training week since applications are heavier and more frequent.

If squirrels resume chewing after a few dry days, treat that spot daily for three to five days to retrain. If you still see determined visits at feeders, add a physical baffle, move the feeder farther from launch points, or rotate in a hot-pepper seed strategy as a companion measure. These layered tactics are consistently recommended by wildlife professionals and backyard birding experts.

Keep a simple log for two weeks: where you sprayed, what you saw, and weather. Switch up tactics if activity shifts. Remember that repellents are part of an integrated approach. Extensions repeatedly caution that effectiveness varies with animal pressure and competing food sources, which is exactly why persistence and pairing with exclusion pays off.

FAQs about Nature’s MACE Squirrel Repellent 40 oz Spray

Does this actually work on both squirrels and chipmunks?

Yes, this formula is marketed specifically to deter squirrels and chipmunks, and the manufacturer also notes it can help with raccoons. The label stresses that results improve with repeated, consistent applications during the first week, then weekly maintenance afterward. Think of it as training the animals to avoid your space.

How long until I see results, and how often should I reapply?

Expect a training period of about seven to ten days. The brand instructs daily applications for the first week, then weekly, and to reapply after heavy rain or irrigation. Independent extension guidance agrees that repellents require persistence and reapplication, especially after storms.

Is it safe around kids, pets, and plants when used correctly?

The manufacturer states the spray is plant-based and non-poisonous when used as directed. Always read the label, avoid applying directly to delicate foliage, and spot-test surfaces first.

What are the active ingredients in the 40 oz ready-to-use spray?

This exact spray contains: Peppermint Oil 0.75 percent, Cinnamon Oil 0.50 percent, Castor Oil 0.50 percent, Soybean Oil 0.25 percent, Garlic Oil 0.25 percent, Sodium Lauryl Sulfate 0.25 percent.

Will rain wash it away?

The product contains a sticking agent to help it last, but you should still reapply after heavy rainfall. That is directly from the brand’s directions and consistent with university extension reminders that all repellents weather over time.

Can I spray my bird feeder and poles?

Yes, the brand’s own FAQ says to spray surfaces squirrels touch most often, like poles, perches, and the base of feeders. They also note no method is perfect if food pressure is high, so combine with feeder placement and hardware like baffles. As a companion tactic, many birders use hot pepper in seed to reduce squirrel feeding time, although practices vary by organization.

Is hot-pepper seed safe for birds and does it really help?

Research shows capsaicin-treated seed significantly reduced both the amount of seed taken by squirrels and the time they spent feeding. Clemson Extension summarizes similar findings. However, Audubon cautions against adding hot pepper to seed and notes capsaicin can harm pollinators. If you try peppered seed, wear gloves, keep it away from children and pets, and prioritize hardware solutions first.

Can I use it indoors, like in an attic?

The product is not for general indoor use. The brand says you can apply it in barns and attics when you are targeting entry points and trails. In my practice, I pair short-term deterrence with long-term exclusion like sealing gaps with hardware cloth, which matches extension best practices.

Will it stain or damage surfaces?

The manufacturer advises testing a small, hidden spot first. They specifically recommend not spraying directly on vehicle paint. For painted furniture and decking, I treat a hidden corner first, then proceed if there is no discoloration.

Can it protect car wiring from rodents?

Yes. The directions explain how to clean nesting debris and then treat reachable wire looms, wheel wells, and under-hood cavities, plus a light perimeter around the parking spot. For persistent issues, experts highlight another proven companion tactic, Honda’s capsaicin rodent-deterrent tape, which you wrap on vulnerable harnesses. Using both, plus sanitation and parking changes, gives you better odds.

How much area does the 40 oz bottle cover?

A single 40 ounce ready-to-use bottle treats up to about 1,400 square feet. Coverage varies with how heavily you apply during the training week and how many chew points you target.

Can I spray it on edible plants?

The brand does not provide explicit edible-crop directions on this product, so I follow a cautious approach that mirrors the company’s edible-use guidance on a different product line. Avoid direct contact with edible portions when possible, treat perimeters and hardware instead, and rinse produce thoroughly if overspray occurs. Always check the label each time you buy because directions can change.

Why do some reviewers say it works great while others say it fades?

That pattern is actually normal with repellents. Efficacy depends on pressure, food availability, and how consistently you apply it. Even on the brand’s own review feed you will see strong wins and some did not last long experiences. That is why I coach clients to combine the spray with one or two physical tactics such as a pole baffle, feeder placement adjustments, or exclusion on structures.

Conclusion

If you are tired of chewed plants, raided bird seed, or mystery bites in your car wiring, Nature’s MACE 40 oz Squirrel and Chipmunk Repellent Spray gives you a humane, plant-based way to take your space back. The 40-ounce ready-to-use bottle is rated to treat about 1,400 square feet, and the directions are simple: a focused seven-day training period, then easy weekly maintenance, with touch-ups after heavy rain. That cadence is exactly what university extension guidance recommends for any scent or taste repellent, which is why homeowners see the best results when they follow it closely.

You are not just buying a spray. You are buying time and control while you nudge squirrels and chipmunks to feed and nest elsewhere. Nature’s MACE spells out where it shines, from garden beds and fruit trees to feeder poles and even problem spots around vehicles, and the formula relies on plant-based essential oils rather than poisons. Used as directed, it is designed to be safe around people, pets, and plants, which is what most families want when they are protecting busy outdoor spaces.

For the most stubborn situations, layer your defenses the way professionals do. Keep up that weekly spray routine, close obvious gaps, and add smart hardware where it helps. If rodents have a habit of chewing under the hood, consider pairing your repellent routine with capsaicin rodent-deterrent tape that Consumer Reports has highlighted, then keep up with cleanliness under the hood to remove scents that draw animals back. Integrated tactics like these are what extension services and mechanics alike point to when pressure is high.
