Rendered suet in a plastic-coated wire cage, hung so the block faces down, brings woodpeckers to a backyard feeder — and that setup only works cleanly in cold weather.
Downy, Hairy, Red-bellied, and even Pileated Woodpeckers will work a suet feeder all winter, and the setup that reaches them is simpler than most feeders sold for the job. Get the fat, the cage, and the hanging height right and birds that already live in your trees will find it within days. Get one part wrong and you feed starlings, grow mold, or quietly grease a woodpecker’s feathers.
Here is what the Cornell Lab of Ornithology’s feeder guidance actually calls for, plus the species notes and warm-weather hazards that decide whether the block helps or harms.
What Kind Of Suet Do Woodpeckers Actually Want?
Buy commercial rendered suet cakes, which are mostly beef or mutton fat and hold their shape far better than raw fat. Plain or insect-and-peanut blends both work, and suet is a known draw for woodpeckers, nuthatches, chickadees, and jays.
Raw suet turns rancid fast once temperatures climb above freezing. Save it for real winter.
Check the label before you buy, because corn, cornmeal, and peanuts in a homemade or cheap cake can support bacterial growth. Stick with reputable brands, or refrigerate cakes containing those ingredients until you hang them.
Which Feeder Design Works Best For Woodpeckers?
A plastic-coated wire cage is the standard safe housing, and an upside-down or tail-prop model gives woodpeckers the advantage. The cage protects the cake from weather and squirrels, and the coating keeps feet and tongues off bare wire.
The down-facing trick matters when starlings and jays raid the feeder. Hanging the suet so the block faces downward forces birds to cling upside down, and woodpeckers and nuthatches handle that posture far better than a starling does. A feeder can hang from a branch, mount flat to a trunk, or sit on a platform — but the downward face is what filters the guest list.

Where Should The Feeder Go?
Hang the feeder beside trees or a brushy edge where woodpeckers already work. Placement decides success more than any product choice does.
Downy Woodpeckers are the most common backyard suet visitor and show up in most of the continental US. Red-bellieds favor yards with woods nearby. Pileateds visit suet feeders sometimes, and standing dead trees raise the odds they stay on the property.
- Leave safe snags and dying trees standing — they offer foraging, roosting, and nesting sites no feeder can replace.
- If nothing visits within several days, scatter a little seed on the ground nearby so birds notice the spot.
- Add black-oil sunflower seed, peanuts, or chunky peanut butter for a wider crowd, especially Downy Woodpeckers.
Will A Suet Feeder Stop Woodpeckers Damaging Your House?
No — a suet feeder is not a reliable fix for siding and trim damage. The feeder may redirect some drumming and probing, but it can also pull woodpeckers closer to the house.
That number is worth knowing before you hang a block as pest control. Use suet to watch birds, not to protect a wall. When a woodpecker is working a wall, the feeder is a separate project.

Common Questions
Do woodpeckers prefer suet over seed?
Woodpeckers favor suet, and Downy Woodpeckers in particular tend to choose suet cages over seed feeders. They will still take black-oil sunflower seeds, peanuts, and millet, so a mixed offering keeps them around between visits to the suet block.
Can I feed suet in summer?
Stop offering suet and peanut butter once heat sets in. Softened fat coats feathers, interferes with their function, and can smear incubating eggs. Rendered suet holds its shape to about 90°F but softens above that, so swap to seed for the warm months.
Why are starlings taking over my suet feeder?
Starlings are strong and will exploit a block that sits flat. Hang the suet so the food faces down, forcing birds to cling upside down. Woodpeckers and nuthatches manage that easily, while starlings and jays feed less effectively from that angle.
