Of all the development stages of the boxwood moth, the caterpillars are the most dangerous. It is they who can eat the bush leafless. But first, a lot of eggs have to be laid somewhere. Detecting and eliminating them would be a major step in combating them.

- first eggs are laid aroundin April
- second egg laying followsin July

Each egg-laying date is heavily dependent on the weather, which is why the time cannot be narrowed down more precisely. Set up a pheromone trap from mid-May. If the first moths stick to it, you should carry out daily checks from now on.
Where and how many eggs does the boxwood moth lay?
Each butterfly laysup to 150 eggs. He chooses the green foliage of the boxwood as a storage location. He places the eggs on theundersides of the outer leaves, about 20 of them close together. We prefer to choose a boxwood that has not yet been infected.

Tip
Cover the box with a close-meshed net in spring
The bush tree grows very slowly. It is very unfortunate if it has to be cut back excessively because of boxwood moths. It makes more sense to prevent an infestation by covering it with a close-meshed net in spring. This makes it more difficult for the butterflies to lay their eggs.
