Update 12 June 2026
BOX TREE CATERPILLER
The first moths of the year have been spotted, and sightings are set to increase as the warm weather approaches.
It is still too early to treat. Trapping male moths with pheromone traps does not reduce the damage. Only some of the males are caught, and the number of caterpillars remains high.
The next treatment period will be around the beginning of July. Keep an eye on our updates.
