“Zombie Squirrels” Spark Concern Across U.S. After fears over “zombie rabbits,” Americans are now being warned about squirrels with oozing sores, wart-like lumps, and disfigured faces. Photos and videos shared online show squirrels covered in grotesque growths, prompting alarm.
Experts say the condition is a naturally occurring disease called squirrel pox (or squirrel fibromatosis), which spreads easily through saliva or mosquito bites — especially at feeders where squirrels gather.
Wildlife biologist Shevenell Webb from Maine’s Department of Inland Fisheries and Wildlife confirmed that while the disease looks scary, it’s not dangerous to humans, cats, or dogs. Most infected squirrels recover unless the growths affect vital organs or block their vision or ability to eat.
Staff at Evelyn’s Wildlife Refuge note some cases may also be caused by botfly parasites, which require professional care to remove. They’re urging the public not to handle infected squirrels.
Though shocking to see, experts advise not interfering, and suggest removing backyard feeders during outbreaks to slow the spread. Many squirrels recover, with one wildlife fan sharing: “He beat the worst squirrel pox I’ve seen — scars remain, but he’s back to normal.”
