How to Keep Squirrels Out of Garbage Cans: 7 Deterrents That Work

Squirrels treat garbage cans as a buffet. Once one learns that a can holds food scraps, it returns every night, chews through plastic lids, and scatters trash across the yard before dawn. The fix is not a single trick but a layered routine: store cans out of reach, remove the food smells that draw attention, and make the can hard to tip or open. The same animals dig through planting beds, and the barrier logic used to keep squirrels out of garden beds applies to trash as well, because removing the reward and blocking access works everywhere. Seven proven deterrents, used together, end the raids for good.

Why Squirrels Keep Coming Back to Your Trash

Understanding the habit explains every deterrent that follows. Squirrels raid cans for the same reason they raid bird feeders: the food is easy to find, and the can is easy to open.

What Draws Them to the Can

Food scraps, greasy packaging, and pet waste carry smells that squirrels detect from a surprising distance. A can sitting in the sun releases odor faster, which is why raids peak in warm months. Once a squirrel finds a reliable food source, it returns night after night and teaches nearby animals, so a single raid can become a neighborhood-wide problem within a week.

How They Get In

Squirrels climb siding, fences, and trees, then jump onto can lids. Plastic lids flex under their weight, and thin plastic cans get chewed open at the rim. They also knock cans over to spill the contents, which turns a lid problem into a mess problem that attracts every other scavenger in the area. Defense has to cover climbing, opening, and tipping at the same time. Kitchen habits feed the cycle too: scraps that go down the disposal never reach the can, but a leaking connection undoes that benefit, so check the drain line plug on disposal and dishwasher connections during routine maintenance and replace it when the rubber starts to crack.

Signs that squirrels have found your cans:

• Scattered trash and torn bags around the can
• Chew marks or flexed plastic near the lid rim
• Tipped cans with contents dragged a few feet away
• Gnawed food packaging or droppings on the ground

Cut Off the Food Supply

The fastest way to make a can boring is to keep food waste out of it. Less smell in the can means fewer visits from every scavenger in the neighborhood, squirrels included.

Bag, Freeze, and Double-Bag

Always use a trash bag, because loose scraps coat the inside of the can with residue that no rinse fully removes. Freeze smelly items such as meat trimmings, fish bones, and chicken carcasses until pickup day, then drop them into the bag frozen. Double-bagging contains the juices that would otherwise pool in the bottom of the can and turn it into a permanent attractant. Tie the bag shut before lifting it into the can, and lower it instead of dropping it, since a split bag coats the interior with exactly the smell you are trying to avoid.

Run Scraps Through the Disposal

Vegetable peels and plate scrapings belong in the disposal rather than the trash. A clean disposal keeps working without odor buildup, so follow a routine like the one in this garbage disposal cleaning guide: run cold water while grinding, sharpen the blades with ice cubes, and finish with citrus rinds to freshen the chamber. Scraps that disappear down the drain never reach the can, which is the whole point.

Compost with Care

An open compost pile is just another food source. Use a covered bin with a tight-fitting lid and bury fresh scraps under finished compost so the smell stays low. Keep the pile away from fences and trees that give squirrels a launching point toward the cans, and turn the pile weekly so food waste breaks down instead of lingering.

Store Cans Out of Reach and Out of Sight

Storage is the single most effective deterrent on this list. A can that squirrels cannot reach is a can they cannot raid, no matter how tempting the contents.

Garage, Shed, or Enclosure

Keep cans in the garage or a shed until pickup morning. That limits the hours the can is exposed and removes the visual cue that tells squirrels food is available. If indoor storage is not possible, build a simple latched enclosure or use a storage cabinet designed for cans, and keep the door closed so the cans stay out of sight between pickups.

Put Cans Out Late

Set cans at the curb in the morning on pickup day rather than the night before. Fewer overnight hours means fewer chances for a raid, and it keeps the sidewalk clear of bags that get dragged open by passing animals. Check the collection schedule for your address, because pickup times vary by route and shift around holidays. When a holiday moves collection, put cans out the night before the adjusted day instead of a week early, and bring the empty cans back inside the same afternoon.

Protect the Rest of the Yard

Squirrels dig for food everywhere, so trash is only one target in a larger pattern. Flower bulbs planted in fall are a favorite, and the strategies for protecting flower bulbs from squirrels use the same barrier logic that works on cans: wire mesh over planting beds, baffles on bird feeders, and clean ground under trees so fallen seed does not pile up.

Clean the Cans and Use Natural Repellents

A clean can smells like nothing, and a neutral-smelling can does not attract attention. Repellents add a second layer of protection for problem areas around the house.

A Regular Cleaning Routine

Wash cans monthly with a hose, soap, and a long-handled brush, or use a pressure washer on a low setting. Dry them upside down so water does not pool in the bottom. Rinse the area where you wash them so suds and food bits do not wash toward the foundation and create a new attractant.

Deep-Clean Steps

Work through these steps once a month:

1. Empty the can and rinse it with a hose to loosen residue.
2. Scrub the inside and the lid with soapy water and a stiff brush.
3. Rinse thoroughly and tip the can upside down to drain completely.
4. Sprinkle baking soda in the bottom between washes to absorb odors.

Repellent Sprays and Scents

Natural sprays made with vinegar, hot pepper, or ammonia discourage squirrels without harming pets or plants when used as directed. Reapply after rain, since most washes off within a week. A working disposal supports the whole effort: when the garbage disposal troubleshooting basics are handled and the unit runs smoothly, scraps stay out of the trash where they belong instead of fueling the nightly buffet.

Secure the Can Against Climbing and Tipping

Squirrels are persistent climbers and strong enough to tip a half-full can. Physical security stops the methods that smell and cleaning cannot.

Weights, Straps, and Stakes

Add weight to the bottom of the can with a brick, a sandbag, or gravel in a sealed container so it cannot be tipped over. Bungee cords stretched over the lid add tension a squirrel has to fight, and a strap or stake through the handle anchors the can to a fence post or a wall hook. A can that does not move is a can that does not spill.

Metal Cans and Locking Lids

Metal cans resist the chewing that ruins plastic, and locking or hinged lids defeat prying. If you keep plastic cans, choose thick-walled models and replace any lid that shows chew marks, because a damaged lid is an open invitation. Match the can size to the household so the bag fits without bulging the lid open.

Pole Mounts and Grease Barriers

On pole-mounted cans, grease the pole below the can so squirrels lose traction before they reach the lid. For freestanding setups, trim branches to at least 6 feet away from cans and feeders so nothing gives a squirrel a jump point. Motion-activated lights add a final deterrent for nighttime visitors.

Deterrent Methods Compared

Two plumbing habits close the loop on food waste. Grease and fibrous scraps poured down the drain clog the line, so handle them through the disposal or in the trash carefully, and when a blockage does happen, clearing a clogged garbage disposal is a routine DIY repair you can finish in an afternoon. A weekly garbage disposal cleaning routine keeps the sink fresh so food smells never drift toward the cans. Combined with storage, weights, and regular washing, the seven deterrents make the trash the least interesting thing in the yard.
