I’m Kayla, and squirrels think my yard is their snack bar. Last spring, they chewed through my tomatoes, nibbled my pumpkins, and even tried my patio chair cushions. Cute? Sure. But not when they stare you down while stealing a cherry tomato. You know what? I took it personal.
If you’re curious about why these furry bandits act the way they do (and when they’re most likely to raid your garden), The Old Farmer’s Almanac has a quick explainer on squirrel habits and pressures that helped me time my defenses.
So I went all-in on natural repellents. Sprays, granules, DIY mixes. I tested them in my garden beds, around my bird feeder, and by the attic vent. Some worked great for a while. Some… did not. Here’s the real story. If you’d like every gritty detail—my day-by-day notes, photos, and the final scorecard—you can find it here.
One quick shortcut if you’re tired of the trial-and-error is to grab a premixed, plant-safe spray from Arena Naturals, which ships ready to use and is gentle around kids, pets, and veggies.
My setup (so you can picture it)
- Small veggie beds (tomatoes, basil, strawberries)
- A bird feeder on a metal pole
- A shed and an attic vent squirrels love to explore
- One dog, two kids, nosy neighbors who comment on smells (bless them)
I wanted things that were safe to use near kids and pets. And I didn’t want my yard to stink all the time. Turns out that last part is tricky.
Mighty Mint Peppermint Spray: Fresh but Fickle
This was the first thing I tried: Mighty Mint Rodent Repellent Spray. It smells like a candy cane shop. I sprayed it on the baseboards in our mudroom, around the back door, and along the shed floor.
- What happened: For two days, no squirrel tracks by the door. They hate that mint blast.
- The catch: After a heavy rain, it faded fast outside. I had to re-spray every 2–3 days in hot weather.
- Bonus: Safe around my dog. Also made the mudroom smell nicer than my gym shoes.
Verdict: Great for indoor edges and porches. Outside, it’s short-term.
Squirrel MACE: Good Around Plants (But Reapply)
Next up, Squirrel MACE by Nature’s MACE. It’s a plant-safe spray with mint and garlic. I used it around my tomatoes and pumpkins.
- Week 1: It worked. The new flowers stayed. No bite marks.
- After storms: I had to spray again the next morning, or the squirrels came back.
- Smell: Strong at first. It mellowed by the afternoon.
Real example: In June, I sprayed Monday, skipped Thursday after a storm, and found a half-eaten tomato Friday morning. Lesson learned.
Verdict: Solid for gardens if you’re okay with a routine. Think of it like sunscreen for your veggies.
Critter Ridder Granules: The “Spicy Line” Trick
I tried Havahart Critter Ridder granules along the fence line and around the bird feeder pole. It uses black pepper and capsaicin.
- It made a “no-go” ring for about a week in dry weather.
- Rain cut that down to about two days.
- I also used Critter Ridder spray on the trash can lids. That part was great. No chew marks after.
Pro tip: Don’t sprinkle it where you’ll kneel. I learned that the hard way while weeding. Spicy knees are not fun.
Verdict: Works best as a boundary line. Reapply after rain.
Bonide Repels-All Granules: Stinky, But It Works
Repels-All smells like egg, garlic, and something funky. My husband called it “swamp soup.” I sprinkled it near the attic vent and under the deck.
- It kept squirrels from nosing the vent for about 10 days.
- Neighbors asked, “Do you smell that?” Oops.
Verdict: Effective near spots you don’t hang out, like under decks or along fence gaps.
Shake-Away Granules: Predator Smell, Mixed Results
I tried Shake-Away granules (predator scent). I used it along the back fence and under the hydrangeas.
- First two nights: Zero digging. I was shocked.
- Then a brave squirrel came anyway. Like he read the label.
Verdict: It can spook them for a bit. Works best if you rotate with other products.
DIY Mixes I Actually Used
I love a cheap trick. Some worked; some made a mess.
- Peppermint oil + water + a drop of dish soap in a spray bottle: Good for porch rails and the shed door. Needs daily use in heat.
- Cayenne + garlic + water: This kept squirrels off my pumpkin vines for five days in July. But it clogged my sprayer. I used a cheesecloth filter after that.
- Orange oil + vinegar: Smelled like a cleaning day. Mild effect for two days near the trash bins.
Please be careful with pepper sprays. Don’t mist it on bird seed. Use hot pepper suet instead. Birds don’t mind pepper, but the dust can bug you and your pets if it goes airborne.

Bird Feeder Fix: Hot Pepper Suet and a Baffle
I’ll be honest. Sprays helped, but hot pepper suet cakes helped more. I switched to a hot pepper blend and added a wide baffle on the pole.
Real example: Before the swap, squirrels sat like little kings under the feeder. After the switch, they tried for two days, got mad, and left. Did one of them yell at me? Felt like it.
What Flat-Out Didn’t Work For Me
- Ultrasonic gizmo from a big box store: I returned it. Squirrels used it like a stereo.
- Lemon peels: Cute idea, zero effect after a day.
- Irish Spring soap chunks: Looked funny, no change at all.
The Smell Problem (Let’s talk about it)
Natural often means smelly. Peppermint smells nice, but garlic and egg blends linger. I used those near the fence, not the patio. If you have porch dinners, plan where you place the stinky stuff. On the flip side, when I was testing natural body lotions that actually smell amazing I realized you can get plant-based products that your nose will love—just maybe not for squirrels.
Little Things That Helped A Lot
- Water schedule: I spray in the evening so it sticks overnight.
- Rotate scents: Mint one week, pepper the next. They get lazy when it’s the same smell.
- Close gaps: I used 1/4-inch hardware cloth under the deck step. Squirrels hate that more than any spray.
- Clean up fallen seed: A seed tray under the feeder saves a ton of drama.
- After rain: I re-spray the same day if I can. Rain is their green light.
- Plant a ring of marigolds: I didn’t get them in the ground this year, but many gardeners swear by a cheery border because marigolds give off a scent that squirrels dislike.
So… did natural repellents work?
Yes, with effort. None of them were magic. But mixed together, they helped a lot.
- Best for gardens: Squirrel MACE or Critter Ridder, plus a weekly routine
- Best for doors and sheds: Mighty Mint (easy and fresh)
- Best for fence lines and “keep out” zones: Repels-All granules (stinky but strong)
- Best for feeders: Hot pepper suet + a baffle, hands down
Would I buy them again? Yep. I keep Mighty Mint for quick spray jobs. I use Critter Ridder for borders. And I bring out Repels-All when I see fresh digging near the vent.
One last thing. Squirrels are stubborn. I had a bold one last fall who stared me down while I was holding the spray bottle. I laughed, then sprayed the fence line and put on fresh hot pepper suet. He left. Slowly. Like I offended him. Maybe I did.
If you want fewer chew marks and fewer side-eye squirrel standoffs, start with mint spray for doors, a pepper line for beds, and a baffle on the feeder. Keep it simple, keep it steady, and you’ll see a difference.
