Box Tree Caterpillar Nematodes offer a targeted solution for combating the widespread summer pest, the box tree caterpillar, which has become increasingly common across the UK. This specialized nematode mix covers up to 60 sq.m and is formulated with Steinernema nematodes. These nematodes strategically target the caterpillar, effectively killing the pest and reproducing inside to release more nematodes into the surrounding environment.

Box tree caterpillars, emerging in significant numbers, encase box trees in webs as they develop. As they hatch, these caterpillars swiftly defoliate the plant, consuming leaves and stems, hindering photosynthesis, and potentially leading to the death of untreated plants. Gardening Naturally Box Tree Nematodes offer a proactive solution, requiring application during the caterpillars' most active period between March and October. 

Pest Appearance: Hatching as green and yellow caterpillars with a black head, they mature and develop black and white stripes on their bodies.

Infestation Indicators: Gardeners become aware of box tree caterpillar infestations when they observe defoliation, discover webbing, and notice caterpillars on box plants.

Initial Signs: Caterpillars consume box leaves, producing webbing over their feeding area. Plants may also display patches of dieback, particularly noticeable on trimmed plants.

Ideal Application Conditions/Soil Temp: Avoid exposing nematodes to freezing or high temperatures. The minimum soil temperature for application is 10 degrees.

Storage Guidelines: Store nematodes promptly after delivery, keeping them in the fridge or below 5 degrees until the expiry date on the package.

Application Tips: If using over plants, water them within 30 minutes of application to wash the nematodes off the leaves and back onto the soil. The soil should be kept moist for three to four weeks after application.
