How to Squirrel-Proof Your Backyard: Tips for Protecting Your Plants

You spend all weekend working on your lawn, nurturing seedlings, weeding, watering with care, only to wake up the following day and find it was all for nothing. 

Dirt everywhere. 

Tulip bulbs? Gone. 

The culprit? A tiny, twitchy-tailed rodent with zero remorse.

Squirrels are cute and all, but they unfortunately also dig, chew, raid, and treat your backyard like it’s theirs. 

Let’s walk through squirrel-proofing strategies that actually work.

How to Protect Your Plants from Squirrels

1. Install Physical Barriers

Physical barriers are some of the most effective tools in your arsenal for keeping wildlife out. 

• Garden fencing: Use mesh fencing with openings no larger than 1 inch. Make sure it’s tall enough to deter climbing and bury the bottom a few inches underground to stop diggers from sneaking under.
• Protective plant cages: Ideal for seedlings and delicate plants. Wire cages or cloches keep curious critters out while still allowing sun and rain in.
• Netting and cloches: Use lightweight netting or dome-style cloches over raised beds and planters. They deter squirrels without blocking airflow or light.
• Greased poles for bird feeders: Squirrels may be acrobats, but they’re not fans of a slippery climb. Greasing the pole makes bird feeders harder (and funnier) to access.
• Hardware cloth over soil: Laying mesh over areas where bulbs or seeds are planted keeps squirrels from digging. Plants can still grow through, but their roots stay protected.
• Repair broken vent covers and soffits: Small openings along your home’s exterior can become squirrel condos overnight. Seal or screen them to block entry.
• Keep bird feeders squirrel-resistant: Use feeders with baffles or weight-sensitive perches to keep squirrels from treating them like snack dispensers.

2. Consider Natural Repellents and Scents 

The biggest question we get as a pest and wildlife control company is: Do they actually work? 

Squirrels are sensitive to strong scents and spicy flavours, so scents like peppermint, vinegar, or garlic may dissuade them, but unfortunately, it will not keep them away. How often have you seen your neighbourhood squirrel take a nice bite off your jalapeno, leave it, and then come right back for another treat?

That being said, there are some scents that may discourage squirrels from feeding in an area.  They are:

• Natural repellents: Sprinkle or spray scents that squirrels can’t stand around your plants and beds. Popular options include cayenne pepper, garlic spray (pungent), vinegar (sharp and unpleasant), and peppermint oil (bonus: your garden smells minty fresh)
• Commercial repellents: Available at most garden centres, these come in sprays or granules and often use spicy compounds or predator urine (like fox or coyote) to trigger the “danger” instinct in squirrels.
• Rotate your repellents: Squirrels are clever little foragers. If you use the same smell for weeks on end, they may just learn to ignore it. Switch it up every couple of weeks to keep them guessing.
• Apply wisely: Focus on garden edges, the tops of fencing, mulch beds, and around the base of plants. Reapply after rain or heavy watering to maintain effectiveness.

3. Maintain Your Yard to Make It Less Inviting For Squirrels

A few simple maintenance habits can make your space far less attractive to curious (and hungry) rodents.

• Trim tree branches: Squirrels use overhanging limbs like launch pads. Keep branches trimmed at least 6–8 feet from your roof, fences, and bird feeders to cut off their aerial access.
• Pick fallen vegetables and nuts: Vegetable shrubs and nut-bearing plants are squirrel magnets. Don’t let fallen snacks linger; scoop them up regularly before word gets out.
• Secure compost bins and garbage: Use bins with locking lids and avoid tossing in sweet-smelling scraps like melon rinds or bread crusts. Compost can be a big attractant if not managed properly.
• Avoid leaving pet food outdoors: Leftover kibble on the porch? Might as well put up a neon sign. Feed pets indoors or bring dishes in when they’re done.
• Remove brush piles and debris: Stacked wood, brush, or leaves offer cozy nesting spots. Keep your yard tidy to reduce hiding places and discourage long-term stays.
• Mow the lawn regularly: Tall grass and overgrown areas give squirrels great cover for sneaking around or hiding stashed food. Keeping grass trimmed removes their cover.
• Clean up garden waste: Dead plants, dropped veggies, and excess mulch can attract both squirrels and insects—clear it out as part of your seasonal tidy-up.
• Install motion-activated sprinklers or lights: Sudden movement or water jets can give squirrels a not-so-subtle hint they’re not welcome.

4. Avoid These Missteps

When it comes to squirrel control, good intentions can go hilariously (or disastrously) wrong. Here’s what not to do if you want to keep things safe, legal, and effective:

• Don’t feed squirrels. That overflowing bird feeder or open compost bin is asking for trouble. Feeding wildlife encourages repeat visits and makes squirrels bolder.
• Avoid poison or glue traps. They may seem like easy fixes, but they’re dangerous, inhumane, and often illegal, depending on your province. They also put pets, children, and non-target wildlife at risk.
• Don’t block off nesting areas without checking for babies. Sealing off an access point while a mother squirrel is still inside, or worse, separated from her young, is not something you want to do. 
• Don’t assume one squirrel = one problem. Squirrels often travel in family units or revisit the same territory. If you see one, assume there are others.
• Don’t relocate squirrels. In many municipalities, it’s illegal to trap and relocate wildlife without a permit. Plus, humane relocation needs expertise. Relocated squirrels often don’t survive, they struggle to find food and shelter in unfamiliar areas.

When Squirrel-Proofing Isn’t Enough: Call In Humane Wildlife Trapping Experts

You’ve tried the pepper spray, trimmed the trees, and even reinforced the fence, yet the squirrels are still having a party in your yard—and staying. It’s time to consider humane wildlife trapping and removal. Here’s what that means:

• Live traps only. No sticky stuff, no snap traps; just safe, humane cage traps designed to contain (not harm) the animal.
• Strategic placement. Traps are set in high-traffic areas based on squirrel behaviour and entry points.
• Frequent checks. Animals are never left in traps for extended periods (because that’s just not humane).
• Minimizing stress. Humane trapping techniques aim to reduce fear and injury during capture, including baiting methods that keep squirrels calm inside the trap.
• Release or professional handling. Depending on local regulations, squirrels may be released nearby or managed by wildlife officials.
