Oak Processionary Moth

Every year, measures are taken to control the oak processionary caterpillar in municipal trees within the municipality of Wassenaar.

The municipality is fully committed to proactive biological pest control. This includes installing additional birdhouses and planting a variety of plants, trees, and bulbs. As a result, the oak processionary caterpillar’s natural predators are present early on.

Caterpillars and nests of caterpillars are also sucked away so that the caterpillars cannot spread further. With this type of control, it is important that the protocol of spotting, recording and acting is followed accurately.
