Study: Nature Helps Reduce Oak Caterpillar Numbers

Greenery Supports Natural Predators
Fewer caterpillars were also found when ivy was planted around trees. And flowers and herbs along roadsides lured to natural enemies like parasitic wasps and flies which also helped control the pest. These methods provide an ecological alternative to conventional practices such as the use of biocides and vacuuming of the subterranean nests.

Future Focus on Reducing Chemicals
The oak processionary moth has fine hair that can irritate to cause itching, rashes and breathing difficulties. Brabant's provincial executive for nature and environment Hagar Roijackers welcomed the research findings, underlining the importance of biological solutions. The aim is to reduce the use of most biocides. To facilitate this transition, the agencies have produced how-to videos for both towns and residents. Because the caterpillars are appearing ahead of schedule this year, thanks to a warm spring, local governments are asking the public to report sightings so they can be removed quickly.
