Box Moth Caterpillar Control Nematodes 30sqm x 2 (2 sachets)

Box Moth Caterpillar Control Nematodes (Nematode Steinernema) are microscopic worms that seek out box tree moth caterpillars, then feed and multiply inside them to stop these devastating pests damaging your box (Buxus sp.) plants. Nematodes are naturally found in soil—by using this product you are simply topping up the natural population.

Box tree caterpillar has become increasingly noticeable across the UK, emerging in significant numbers and encasing box trees in webs as they develop.

Damage: As they hatch, these caterpillar pests can totally defoliate plants, consuming leaves and stems, slowing photosynthesis—often leading to the death of infested plants. Caterpillars are green and yellow with a black head, developing black and white stripes as they mature. Signs of infestation include defoliation, webbing, and visible caterpillars on box plants.

Nematode products are renowned biological controls, providing many benefits over traditional gardening chemicals and are a key ally for organic gardeners. All products are simple to apply, safe to use, and harmless to children, pets, birds, and wildlife.
