Moth beaten

In response to ‘VT’s question on pyrale de buis, there is a misconception that the treatments available commercially are chemical-based.

In fact, they contain a bacterium, Bacillus thuringiensis,  that specifically targets the caterpillars, so can be considered as a natural ‘predator’ and ecologically friendly. A variant of the bacterium is also useful in preventing and treating infestations of processionary caterpillars in both oak and pine.
