Masses of caterpillars on barberry? - Tips for natural control
A single caterpillar still does not cause any galling on a barberry hedge. If, however, hosts of larvae fall over their barberries, effective countermeasures should be taken. The handle to the chemical insecticide is not an option in the natural home garden. These tips show how the control of caterpillars on peat thorns succeeds with ecological means.

Cut the shoots back by a third to catch as many caterpillars as possible at all stages of development. The rest of the rabble spray with a sharp stream of water. Before doing so, spread out foil under the shrubs to catch the larvae along this path and dispose of them with household waste.

An effective and natural spray against caterpillars you can make yourself. To do this, dissolve 8 ml of Niemöl in 1 liter of water and add 2 ml of Rimulgan as emulsifier.

Monotonous fruits are spared so as not to undermine their own reproduction.
