Swiss foxes suffer as deadly mite infestations spread across regions

A growing number of foxes in Switzerland are falling seriously ill due to a severe mite infestation. Over the past two years, around 150 cases of foxes with unusual symptoms—such as hair loss, crusty skin, and a rat-like tail—have been reported to cantonal hunting authorities. Most sightings occurred in Bern, Zurich, and Lucerne.

One such case involved a fox in Liebefeld, near Bern, which repeatedly visited a resident's garden over several weeks. At first, the animal kept its distance, but it soon became unusually tame, eventually settling into a garden basket. The fox's condition worsened: its fur matted, a swollen hump formed on its spine, and it barely moved.

The animal was later diagnosed with mange, caused by *Sarcoptes scabiei* mites. Due to the severity of the disease, the fox had to be euthanised to prevent further suffering. Wildlife experts explain that sick foxes often lose their natural fear of humans and stay in one place due to reduced mobility. Authorities urge the public to report any foxes that appear lethargic, unusually approachable, or linger in the same spot. These symptoms often indicate fatal diseases like mange or distemper, which require immediate action.

The rise in sick foxes highlights the need for public vigilance. Anyone encountering a fox with abnormal behaviour or physical symptoms should contact a wildlife warden or local hunting association without delay. Early reporting helps prevent prolonged suffering and limits the spread of disease.
