Boxwood growers have to be tackled with different measures at different times
Successfully combat boxwoodsuckers: depending on the right time
The boxwood cinder (Cydalima perspectalis) is a nocturnal butterfly from East Asia. The pests have been around since about 2019 in Germany and neighboring countries. As so-called neozoans (ie invasive species), they hardly fear natural enemies in this country, and the animals also have a similar climate and feel very well here.
Biology and lifestyle determines the right time
Only those who have informed themselves about the life cycle of the boxwood can effectively tackle the pest. In particular, when biological insecticides such as Bacillus thuringiensis are used, you should know your enemy. The ideal time to use the spray is when the moth is still at the beginning of its development. Since its eggs overwinter inside the boxwood, the caterpillars hatch very early in the year: About the beginning of March, when the temperatures are permanently above about seven to nine degrees Celsius, the big eating begins. Special boxwood caterpillars also help you discover flying butterflies.
Fight boxwood growlers - when to do what
Once one has caught in one of your traps, you must act. Adult female butterflies lay up to 150 eggs in their short, approximately nine-day life. To prevent the offspring from hatching, you have to be quick. Every year between three and five populations occur; h., the fattener multiplies incredibly fast. And so you fight the animals:

2. From the beginning of March
3rd end of April / beginning of May
4. From the beginning / middle of May
Tips
If you want to protect your boxwood from infestation with a phytosanitary net, choose green meshes that are as narrow-meshed as possible - they are visually less noticeable. Only in autumn, with permanent temperatures of less than seven degrees Celsius, the nets can be removed.
