Product Information

Xentari may not be available in your local garden centre, but it is readily available online. 2. Step Two: Switch to Chemical Insecticides Use a clean, disinfected spray bottle to apply Xentari. Spray it as soon as you notice the first caterpillars on your box hedge, both on the top surfaces of the leaves and the undersides, too. Before treating any area or structure used by bats, you MUST consult Natural England, Scottish Natural Heritage or The Countryside Council for Wales, as bats are protected under the Wildlife and Countryside Act 1981.

The caterpillars go through several stages of growth before pupating into adult moths. The pupae can overwinter in debris around the plants, and when the weather warms up again, they emerge as adult moths, ready to lay eggs and start the cycle anew. What is the best box hedge caterpillar killer? Users must comply in full with their responsibilities under the Control of Pesticides Regulations 1986.However, if you’ve caught your infestation late and your boxwood’s life hangs in the balance (like mine has in the past!), then it may be worth using a chemical insecticide. But a word of warning – you should only use chemical insecticides minimally and in a highly targeted way. Here’s how to do this: Pheromone traps and manual removal can only do so much to get rid of box caterpillars. When these aren’t sufficient, you’ll need an insecticide. The most environmentally friendly of these options is a biological insecticide, also known as a natural or organic insecticide. Encourage natural enemies in gardens, for example the predatory bug Orius laevigatus can occur naturally In glasshouses it is possible to use glasshouse fumigants. Glasshouse should be sealed and instructions on the product label must be followed. An organic fumigant based on garlic is available as Pelsis Pest-Stop Biofume Greenhouse Fumigator and can be used when crop plants are present. Products based on the synthetic pyrethroid permethrin are available asDeadFast Greenhouse Smoke Generator, DeadFast Greenhouse Smoke Fumigator

Pesticide control The RHS believes that avoiding pests, diseases and weeds by good practice in cultivation methods, cultivar selection, garden hygiene and encouraging or introducing natural enemies, should be the first line of control. If chemical controls are used, they should be used only in a minimal and highly targeted manner.

OK, so hand removal doesn’t sound all that fun. But when you’ve noticed the start of an infestation, hand removal may be all you need to control their numbers. Simply put on some protective gloves and get to work, removing each caterpillar by hand.Plant invigorators combine nutrients to stimulate plant growth with surfactants or fatty acids that have a physical mode of action against thrips (e.g. Ecofective Bug Control, Growing Success Bug Stop, Rose Clear 3 in 1 Action SB Plant Invigorator and Westland Resolva Natural Power Bug & Mildew). These products contain some synthetic ingredients and so are not considered organic
