The caterpillars of the oak processionary moth have tiny, stinging hairs. These hairs are toxic and can cause health problems upon contact. If your skin comes into contact with them, it can cause intense itching. Red welts or inflammation may develop. Your eyes or respiratory tract can also become irritated. Sometimes, dizziness, fever, or circulatory problems even occur. The symptoms can last from two days to two weeks.
If you discover an infestation on your property, you as the owner are responsible for having the caterpillars removed by a specialist company at your own expense.
