The oak processionary caterpillar is a caterpillar that lives in some oak trees during spring and summer, usually in May, June and July, but due to the colder spring weather in 2021, most nuisance this year will occur in July and August.
Oak trees that house the oak processionary can be identified by a dense spindle around the branches and trunk of the tree. The caterpillars have stinging hairs that are invisible to the naked eye. Contact with the stinging hairs can cause complaints such as itching, bumps on the skin or cold-like symptoms.
Try to avoid contact with the caterpillar. 
Make sure your neck, arms and legs are covered, do not touch the caterpillars and do not sit on the floor. Any children should also be instructed to avoid contact with the caterpillar. In the event of contact, thoroughly wash or rinse the skin with lukewarm water. Alternatively, strip the skin with adhesive tape. Avoid rubbing or scratching.
