I treated 10 trees - 10 ml in 10 litres of water, 2 watering cans per tree in the root area ... there are approximately 100 trees on the piece of land, but I wanted to first see the effect for myself. After about a week, the caterpillars began to avoid the treated trees, no longer climbing onto them. Two weeks after the first application, this behaviour became more obvious: caterpillars that were thrown off by the wind and weather no longer climbed back onto the trees, and other groups marched back down off the tree they were on. In the meantime I watered the trees again with the remedy. I did not see this migration with trees that were not treated. http://www.narayana-publishers.com/Bombyx-processionea-Prozessionsspinner/Homeoplant/b8433(source) (133)
