Box Moth Trap and Refill
The Box Tree Moth caterpillars feed on leaves causing defoliation and dieback. The caterpillars produce webbing tents to protect themselves. Early detection and control are essential as the webbing makes effective control difficult.
This trap should be used between March and October.
The refill allows re-use of the trap for a further season.
Recommended density is 1 traps per 0.5 acres.
Trapping Season: Place traps in an area by mid-March and continue until October. It should be noted that the exact time of insect emergence will vary with location and seasonal variation.
Trap Placement and Density for monitoring: Traps should be placed in an open area where the plants susceptible to attack are being grown. The traps should be mounted at a height of 1.5 to 2 metres above the ground. The current recommended density is 4 traps per hectare; this density is subject to change depending on location and severity of the moth.
Use of Lures: The lure should be kept in the sealed packet until it is needed. Do not try to open or pierce the capsule; just place it in the cage on the trap lid. Dispose of the sachet and used lures well away from the trapping area.
Trap Servicing and Change of Lures: Add approximately 5cm of water with a drop of detergent into the trap bucket. Lures should be changed every 5 weeks. The funnel traps should be emptied weekly to avoid the trap filling and repellency from putrefaction of the caught insects.
This moth is a native of East Asia and was first reported in UK gardens in 2011. An important pest of box plants (Buxus spp.), larvae feed on leaves and in severe infestations can cause defoliation and dieback. Currently established in southern England, late instar caterpillars produce webbing ‘tents’ to protect themselves whilst feeding. Early detection and control are necessary as this webbing makes effective control difficult.
