Description

This natural, chemical-free treatment will help protect box plants and hedges from box tree caterpillar infestation and damage.

If left unchecked, these serious pests can rapidly increase in number, defoliating plants and damaging leaves. In severe cases, they are capable of boring into the bark of mature box plants and killing them.

To catch the problem early, look for flat, pale yellow eggs that overlap each other in a flat sheet on the underside of the leaves. Newly hatched larvae will be greenish-yellow with black heads, and as they mature will develop dark brown or black stripes.

You can also look for clear webbing left on your plants, which indicates a significant infestation.

How to use:

This treatment contains Steinernema carpocapsae nematodes, the most effective species for controlling the distinctive black-striped green caterpillars.

For best results, first use our box tree moth trap (sold separately) to catch and kill male box tree moths and limit the potential for further infestation.

Next, apply the nematodes using a knapsack or large handheld sprayer (with filters removed). Ideally this should be on a wet or humid day in the early morning or early evening.

Empty one sachet into a bucket of 2.5 litres of water and mix thoroughly. Pour this into your sprayer and top up with another 5.5 litres of water so you are left with 8 litres of solution.

Spray plants from top to bottom, covering the whole plant. Apply plenty of solution onto the foliage and directly onto caterpillars where possible, using at least 250-500m of solution per square metre.

After 7 days, repeat using the second sachet to catch any caterpillars missed during the first treatment, as well as newly hatched caterpillars.

Supplied as 2 packs of 25 million nematodes, each treating up to 35m². Harmless to wildlife, pets and humans. Always read the instructions before use.

Key features:

  • Easy to use - dilute and apply
  • Contains 2 x 25 million nematodes
  • Treats up to 35m²
