preventive measures

The most important measure is targeted prevention. Were endangered for a Buchsbaumzünslerbefall are weakened plants. Therefore, a good care and fertilization not only healthy plant growth, but also act as a preventive measure.

Already in the spring you should check your box trees for a caterpillar infestation. The boxwood borer has two to three generations per year, so regular checks are recommended. Because the first larvae still live and eat secretly inside the plant, they are often discovered too late and the plant is already badly damaged.

The feeding damage is still not all: An infestation in many cases causes plant-specific fungal diseases, such as the "Buchdriebsterben".

Tip: The large butterfly is easily recognizable by its characteristic coloring. As soon as the Boxwood Borer lands on your boxwood, you should chase it away. If the butterflies are increasingly observed, stretched nets above the plants keep the insects from landing.

Anyone who discovers the infestation soon enough should collect the caterpillars from the shoots or spray them off with a stream of hard water, pick them up from the ground and dispose of them - but in most cases it is already too late for such measures and chemical sprays are needed.

Tip: Experts recommend using a combination of two sprays. A remedy that works against the boxwood conifer and one against fungal diseases that often occur together with the caterpillar.

The spraying should be done with sufficient pressure and all shoots - also inside the trees - should be completely wetted. The collected larvae are destroyed, so that they can not attack other plants.
