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 Dissolve 3 grams of Xentari granules for every 30 litres of water. This will cover around 30 m² of boxwood surface.

But trust me; this isn’t the case – I’m talking from past experience here! It’s important to act straight away to minimise the damage. So, what can you do? These pests can cause extreme damage to boxwood plants. In short, they strip them of their leaves, which weakens their overall health and destroys their well-kempt appearance. Where to use: For the control of insect pests such as aphids and caterpillars on roses and a range of garden vegetables, Py Bug Killer Concentrate will also control beetles on specified vegetables. Do not apply when bees are actively foraging (use early in the morning or late in the evening).

Another action to take is to use a pheromone trap. Have these up around your boxwood to attract any male moths away from your plants. Installing traps won’t be the only step you need to take, but they’ll give you a heads-up to get your gloves on or an insecticide at the ready.

Unfortunately, box caterpillars leave you few alternative options! While you could normally leave caterpillars and other insects out for the birds, our native birds don’t like box caterpillars much. If it’s your first time seeing these crawly creatures on your boxwood, you’re probably wondering what they are. Well, these are box caterpillars. Spray the whole plant, including the undersides and tops of the leaves, as well as any plants directly beside your affected boxwood. However, DO NOT spray any flowering plants, as a chemical insecticide doesn’t only kill caterpillars – it will kill pollinators like bees, too. In glasshouses it is possible to use glasshouse fumigants. Glasshouse should be sealed and instructions on the product label must be followed.

But how do you know it’s a box caterpillar infestation? To recognise this, you need to know the signs. What Are the Signs of a Box Caterpillar Infestation?Organic control methods may be the best route to go down if you catch an infestation early on. You can tell when you’ve caught it early because the damage to your boxwood plant is minimal. Perhaps you’ve noticed a few caterpillars appear, or you’ve seen some defoliation, but the majority of the plant’s leaves are still intact. Note: This product is dangerous to use around bees. DO NOT apply around areas where bees are actively foraging. 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.
