In 2018 much of the UK had its first experience of Box Tree Moth Caterpillar. Though it has been around since 2011 or so, this pest has increasing made its presence felt recently. Many have seen it after the horse had bolted. With their – in some cases very expensive – box installations reduced to just a bunch of sticks.

From the ground up has tried various solutions over the last two years. Consequently we have tried and trusted plans to address this invasion for our clients, and stop box tree moth caterpillar. Depending on the volume of buxus present we have effective methods to try to prevent infestation. A combination of pheromone traps and direct spraying prevents and cures. Because the traps contain a lure that attracts the male, they are caught preventing any eggs laid by the female being fertilised. However, in 2020 the trap makers suggest that the trap is used purely as an indicator of moth presence. As if half your buxus missing were not clue enough.
Chemical spray or more expensive nematode or biological insecticide solutions are available to treat caterpillars directly. Spray treatment needs to be thorough and get right inside the plant, past the protective web left by the caterpillars. Using a pump spray with a lance gets it right into the plant, ensuring that all the foliage is covered. That’s why using a hand spray is not effective. To kill off any infestation first, repeated treatment every 7-10 days to start, and then approximately every 4-6 weeks between March and October. The spray is absorbed into the plant, and kills the caterpillars as they eat the leaves.
