In the fight against the oak processionary caterpillar, the Amsterdamse Bos is planting flower bulbs from stinzen plants this autumn. These wild spring flowers attract natural enemies of the caterpillar.

The oak processionary caterpillar causes a lot of nuisance every year. The little animal can cause red bumps and in particular a lot of itching in people and animals. In the past, various parts of the Amsterdamse Bos were closed off after a large number of nests were found.

The stinzen plant attracts animals that love the caterpillar, such as parasitic wasps, lacewings, tits and bats. The flower bulbs are planted at the Eikenlaan along the cycle path from the Boswinkel.

At the end of last year, half a million flower bulbs from Stinzen plants were already planted along the Grote Speelweide, while nest boxes were placed this spring to attract birds that eat the caterpillar.
