action must be taken before spring to avoid the proliferation of processionary caterpillars

Like cotton balls on the tips of the pine trees in your garden? Look no further, your plants are infested by processionary caterpillar nests. For the moment, these parasites are in their cocoon, feeding on the pine needles which they weaken. Same cocoon that they should leave in spring, descending from the trunks to bury themselves while waiting to become a butterfly. It is also during this period that they are the most dangerous.
