The oak processionary caterpillar (Thaumethopea precessionea) is the caterpillar of a moth. The caterpillars go in groups (in procession) in the months of May, June and July in search of food. These are oak leaves, hence the name oak processionary caterpillar. After contact with the fire hairs of this caterpillar, symptoms such as itching, skin rash, irritation to the eyes or even to the respiratory tract may occur. As the owner of infected trees, you are responsible for nuisance control. BKC works with professional removal equipment, which removes the oak processionary caterpillars completely and safely. Both the caterpillars with fire hairs and the nests are sucked up and removed. Have you spotted oak processionary caterpillars? Please contact our office for more information.
