Background knowledge and recommended action
The oak processionary moth is a moth native to Europe that develops mainly on oak trees. In Switzerland, it is mainly found in western and north-western regions, and on the southern side of the Alps. After hatching, its caterpillars feed in gregarious clusters on the leaves of oak trees, and large populations can lead to the complete defoliation of infested trees. The oak processionary moth attracts particular attention because the urticating (stinging) hairs of its caterpillars can cause allergic reactions in humans and animals.
