    Early Detection Is Key

    How To Identify Box Tree Caterpillars

    Box tree caterpillars can cause significant damage in a short period of time, so early identification is essential. Look out for these common signs:

    • Green caterpillars with black and white stripes
    • Fine webbing throughout the hedge
    • Chewed leaves and bare stems
    • Brown patches appearing suddenly
    • Moths flying around box hedges during spring and summer

    Early treatment gives the best chance of recovery.

    Monitor Moth Activity

    Adult Box Tree Moths lay the eggs that become damaging caterpillars. Using pheromone traps helps monitor activity and provides an early warning when moth numbers increase.
