Should You Leave Pumpkins Out for Wildlife? What Wildlife Agencies Say

Every October, a post goes viral telling people to leave their old pumpkins in the woods so wildlife can eat them. It sounds kind. Wildlife agencies and extension offices keep asking people to stop.

Where you leave it matters. So does the paint, glitter, or candle wax you put on it. A squirrel nibbling a plain pumpkin on your porch is a long way from a pile of painted jack-o’-lanterns dumped in a preserve.

Local feeding rules and wildlife vary. This sums up what the sources linked here say, and it’s not legal advice.

What the viral post gets right

Animals do eat pumpkins. The US Fish and Wildlife Service says a carved jack-o’-lantern near your door will likely get eaten, including squirrels, raccoons, deer, moose, foxes, mice, and insects.

A wildlife writer at The Nature Conservancy goes further. He says unpainted, uncoated pumpkins are safe and nutritious for wildlife, and many of the animals that eat them already visit bird feeders.

A squirrel helping itself to your porch pumpkin isn’t what agencies are asking people to stop. They’re warning against carrying pumpkins somewhere to feed wildlife.

Why wildlife agencies say don’t

Deer are the biggest worry in the US. Wyoming Game and Fish says mule deer can’t process unnatural foods. It gets many calls this time of year about sickly fawns, and it ties many of them to deer eating foods they can’t digest well.

Deer have four-part stomachs. The microbes in them are matched to what’s available that season. Utah’s wildlife division warns that a sudden change in food can leave deer dying with full stomachs.

Feeding also packs deer together. Utah says herds concentrated by feeding pass diseases like chronic wasting disease (CWD) along more easily. A 2025 study in the Journal of Wildlife Management found CWD prions on deer feeders in a Mississippi study zone where about 30 percent of the deer were apparently infected, and deer touched each other more at feeders than at food plots or oak trees.

CDC says CWD has been found in wild deer in 36 states, and that prions can stay in the soil for years. The feeder study didn’t test pumpkins. It tested the places deer gather to eat. Some states already ban feeding deer. Michigan, for one, defines feed to include fruits and vegetables and bans feeding in the Lower Peninsula.

In the UK, the worry is hedgehogs. The British Deer Society says hedgehogs eating pumpkin right before hibernation can get severe diarrhea and dehydration, then hibernate in poor condition. Cornwall Wildlife Trust and the RSPCA warn about the same risk.

Then there’s what’s on the pumpkin. FWS says a painted pumpkin can be toxic to wildlife if they eat it. Forestry England adds candles and glitter to that list, and the British Deer Society says plastic decorations and candle bits can end up inside animals.

Why the woods are the worst spot

The Nature Conservancy writer’s advice is for a pumpkin or two in your yard. Dump a pile in a preserve, and you’re leaving other people to deal with it.

Illinois Extension says leaving pumpkins on private property or a nature preserve without permission is littering and illegal. A staff member there says pumpkins and straw smother native plants and create moldy little microhabitats, and that pumpkins now grow in preserves, probably from the year before.

The DuPage Forest Preserve District says dumped pumpkins can smother delicate native plants. Rotting pumpkins become breeding grounds for bacteria, fungi, and viruses. Dumping there is illegal and can mean fines. Near roads, they can pull animals into traffic.

Animal by animal

A squirrel, a deer, and a hedgehog don’t face the same risks from your leftover pumpkin.

What to do instead

Compost it. Forestry England says pumpkins are about 90 percent water and rich in nitrogen, so they suit a compost pile. If you don’t have a bin, it says you can bury the pumpkin in your garden.

The RSPCA says birds can eat freshly cut pumpkin and seeds from a bird feeder, off the ground. The British Deer Society suggests turning the shell into a bird feeder, and cleaning it out once it starts to rot. Our piece on keeping feeders up in winter covers what to put in.

Chickens and pigs are the other good fit, with the owner’s okay. We put the full list in what to do with old pumpkins after Halloween, including a checker that sorts your pumpkin by condition.
