How to Buy or Make a Squirrel Proof Bird Feeder
How Do You Keep Squirrels Off Your Bird Feeder?
First, know your enemy! Squirrels belong to a family of mammals known as Sciuridae that include tree squirrels with bushy tails as well as flying squirrels, ground squirrels, chipmunks, and woodchucks.
In the UK, our native squirrels were originally the Eurasian Red variety but they have been largely displaced the American Eastern Grey.
There is a wood behind our house and a large oak tree in our garden so we are overrun with grey squirrels. They are very cute, but like naughty children, can also be very annoying. Their irritating habits include chewing plants, digging in plant pots and tubs, eating bulbs, and even digging up whole plants and playing with them. But their worst crime by far is destroying bird feeders and stealing the bird food inside.
Anyone who has put out a conventional bird feeder containing nuts or seeds will understand what I mean. If it is made of plastic or wood, then they will take it apart by chewing and gnawing it until they can access the food. Trying to make the feeder inaccessible is more difficult that you might think.
Squirrels are not only very smart and cunning but they can do all of the following:
- Leap well over 10 feet
- Climb along or down a thin metal wire
- Chew and gnaw plastic or wood to destruction
- Pull bird feeders to the ground by detaching them from supporting hooks, cable or other fixings
Here is a typical cycle of events that those who underestimate this cunning creature will experience:
- Start with wooden or plastic feeder hung from a bird table, pole, etc. They will easily accesses the feeder, destroy it, and eat the food.
- Relocate the feeder to where you are sure they can't reach. For example, hanging from a bracket mounted 15 feet from the ground on a brick wall of the house. Squirrel climbs the brickwork and destroys feeder as before.
- Hang the feeder from a wire hanging from a tree branch. The critter leaps from the tree to the suspended feeder. If it's made of bite-proof material, then they will get it on the ground and roll it around to empty the contents.
So what can you do to defeat these hungry little rascals? The liberal view is to provide a squirrel-friendly feeding area in your garden. However, they will rapidly remove all the food you provide and then bury what they can't eat, then return to attacking the bird feeders with renewed vigour (you've just provided them with an energy-rich meal!)

Defence no. 1: Enclose the Feeder in a Squirrel-Proof Cage that only Birds can Enter
I made a homemade version by enclosing the feeder in a suspended chicken wire cage.
Unfortunately, an enterprising squirrel (be warned there is always one that is even smarter than the rest and won't give up) jumped onto the cage, prised it open, and squeezed inside. It couldn't get out again. He or she became very stressed and, when I climbed the ladder and retrieved the cage, it made the most dreadful noises, assuming it was about to become my supper. When I released it, it was so upset that it just lay spread out on the grass at my feet waiting to die. However, once I left it alone, it quickly recovered.
So unless you are a first class craftsman, it is probably safer for you and the squirrels to buy a manufactured version of the caged feeder.
No 2. The Baffle to keep the squirrels away from your bird feeder
Here is a typical baffle that you can fix above the feeder to keep the squirrels at bay.
Defence No. 2: Keep Them Away from the Feeder
This is typically done using baffles. These are dome-shaped objects mounted either on the suspending wire or the supporting pole which hopefully prevent the squirrel getting to the feeder.
I had a feeder suspended on a wire about 15 feet off the ground between our oak tree and the house. They simply walked upside-down along the wire and dropped onto the feeder. I then tried homemade baffles and grease on the wire, but neither stopped them.
At one point I left the stepladder next to the suspended feeder (yes I am that stupid) and when I returned, a squirrel had climbed the ladder and leapt onto the feeder.
Defence No. 3: Shut the Food Hatch When They Arrive
Some feeders have a metal sleeve which covers the bottom part of the feeder when they land on it. These only work if the attack is mounted from above, for example, by climbing down the supporting wire.
Defense No. 4: Active Hostility
This is where things gets slightly nasty: squirrels projected through the air at high speeds through whirling blades, high voltage wires, and explosive devices. These are just some of my fantasies.
The most practical devices include adding a motor to the base of the feeder so the feeding area spins when the creature 'perches' on the feeder. This propels them into space.
Typical of these feeders is the . This feeder spins when the squirrel appears on the bottom rail and keeps going until the dizzy squirrel drops to the ground (see entertaining video below). I have slight health and safety concerns here. Droll Yankees' Flipper
Be sure the motorised feeder isn't too high off the ground and avoid the temptation to put a padding pool full of water under the feeder—this would be cruel!
