Squirrel-Proof Bird Feeders in the UK: What Stops Grey Squirrels
Grey squirrels are clever, persistent and widespread across Britain. Which feeders actually keep them out, how far they jump, and what to do if red squirrels visit your garden.

Equipment for this job
A caged tube feeder and a baffle — the two pieces that do most of the work. We deliver to the UK.
18-Inch Squirrel Baffle
A wide black baffle for helping keep squirrels from reaching a hanging or pole-mounted feeder. The cone measures 18 inches (45.7 cm) across. Choose the hanging-hook setup or pole-collar setup to suit your feeder station. Position the baffle so squirrels cannot bypass it from a nearby branch, railing, or roof.
Caged Tube Bird Feeder
A metal tube feeder inside a wide protective cage. The outer cage limits access by squirrels and larger birds while smaller birds can reach the inner seed tube. A top handle makes it easy to hang, and the lid lifts for refilling. Available in black or green. No feeder is completely squirrel-proof, so placement still matters.
- Vertical jump
- About 1.5 m
- Sideways leap
- Up to about 3 m
- Cage gap
- Around 3–3.5 cm lets small birds in, keeps greys out
- Baffle height
- Bottom edge at least 1.2 m off the ground
- Legal note
- Trapped grey squirrels may not legally be released
Why grey squirrels win most of the time
The grey squirrel arrived from North America in the late 1800s and is now found across most of England, Wales and lowland Scotland, and in much of Ireland. It is bigger and bolder than the native red, and a garden feeder is an easy source of high-fat food. One squirrel can empty a peanut feeder in an afternoon and chew through plastic ports to get at sunflower hearts.
No single trick stops them for good. What works is a combination: feeders they physically can't get into, placed where they can't reach, with nothing on the ground to reward them. Miss one of those and they'll find the gap.
Three things that actually work
Most squirrel-proofing falls into three categories. Use at least two.
- A cage: an outer steel guard around a tube feeder, with gaps of roughly 3 to 3.5 cm. Tits, finches, sparrows and Robins get through; grey squirrels and Woodpigeons don't. The cage needs to be far enough from the inner tube that a squirrel can't reach in with its paws.
- A baffle: a wide dome above a hanging feeder, or a cone or tube on a pole with its bottom edge at least 1.2 m off the ground. Squirrels can't climb or reach round it.
- Distance: keep the feeder at least 3 m from fences, walls, sheds and branches. Greys jump about 1.5 m straight up and leap around 3 m sideways.
What doesn't work
Plastic feeders without metal ports get chewed. Thin wire hangers let squirrels slide down from a branch. Grease on poles is cruel and messes up birds' feathers, and it's not recommended by any UK wildlife charity. Chilli-treated seed is sold as a squirrel deterrent; birds can't taste capsaicin, so it doesn't harm them, but squirrels often learn to tolerate it and the dust is unpleasant to handle.
Feeding the squirrels somewhere else works in some gardens and backfires in others. A separate squirrel feeder far from the bird station can keep them busy, but it also feeds more squirrels.
If red squirrels visit
Red squirrels are protected and in decline, surviving mainly in Scotland, Northumberland and Cumbria, Anglesey, parts of Northern Ireland and a few island populations. If reds come to your garden, you're lucky. Many local red squirrel groups encourage feeding them with hazelnuts in a dedicated box feeder — and ask you to report sightings of greys, because greys carry squirrelpox, which is fatal to reds.
Hygiene matters even more in red squirrel areas: clean feeders regularly so disease isn't spread between animals using the same food.
The law on grey squirrels
Grey squirrels are listed as an invasive non-native species. Under the Wildlife and Countryside Act 1981 and the Invasive Alien Species (Enforcement and Permitting) Order 2019, it is illegal to release a grey squirrel you have trapped, or to let one go elsewhere. Anyone considering control should read the official guidance first. For most gardens, excluding them from feeders is simpler and causes no welfare problems.
Setting up a squirrel-resistant station
Put a caged tube of sunflower hearts on a pole or arm with a baffle underneath, 3 m from anything a squirrel can jump from. Hang a suet cage under a wide dome. Sweep up spilt seed under the station every few days, or use husk-free food so there is less spillage. Squirrels that get nothing usually move on to easier gardens within a week or two.
Check the station after you set it up. Watch for a day: where does the squirrel try first? It will show you the weak point, usually a branch you didn't notice or a fence post closer than you thought.
Food choices that help
What you put out changes how hard squirrels try. Sunflower hearts and nyjer in a caged feeder are less rewarding to a squirrel than a mesh feeder full of peanuts, which is the single most squirrel-attracting thing you can hang in a British garden. If you want to offer peanuts, keep them inside a cage or under a baffle, and accept that they will be the first target.
Suet blocks and fat balls are another favourite. Hang them under a wide dome and well away from fences. A squirrel that has to work for an hour for a few crumbs will usually give up and go next door, where the feeders are easier. Consistency matters: if you leave a weak spot one weekend, the squirrels learn the station is worth checking again.

Frequently asked
What is the best squirrel-proof bird feeder in the UK?
A caged tube feeder with metal ports and gaps of roughly 3–3.5 cm, hung under a baffle and kept 3 m from fences and branches.
How far can grey squirrels jump?
About 1.5 m straight up and roughly 3 m sideways from a fence, wall or branch.
Does chilli seed stop squirrels?
Birds can't taste capsaicin so it won't harm them, but squirrels often get used to it. Physical barriers work better.
Can I release a grey squirrel I catch?
No. Grey squirrels are an invasive non-native species and releasing one is illegal in Great Britain.
