Adjustable collar anti-caterpillar processionary pine - Diameter 55cm

Effectively prevent the proliferation of pine processionary caterpillars with the SOLABIOL collar. This innovative system captures caterpillars as they emerge from their winter nests and descend along the trunk. Stopped by the strapping composed of foam and flange, the tracks are then led to the inside of the collector bag. This trap prevents these pests from burying themselves in the ground and becoming the next generation of breeding butterflies.
