Recent unsettling images of squirrels with wart-like growths have prompted new warnings from wildlife experts. These “zombie squirrels,” a nickname coined online, have been seen in several states, causing public concern.
The condition is not a new epidemic but a known virus called squirrel pox, or fibromatosis. This poxvirus causes large, tumor-like growths on the skin but has been documented for decades.
The disease spreads easily among squirrels in areas where they congregate densely, such as around bird feeders. It is transmitted through saliva on shared food sources.
Experts stress that the virus poses no threat to humans or pets. While the sores look alarming, the animals are not dangerous to people.
In some cases, these “zombie” symptoms can also be caused by botfly larvae, which burrow under the skin to grow. This is a separate condition from the poxvirus.
Wildlife officials strongly advise a hands-off approach. Do not attempt to capture or treat the animal, as this causes stress and risks injury.
The best action is to remove bird feeders to discourage gatherings. This helps slow the virus’s spread, allowing the natural cycle to run its course.
