Asian hornet nests on Portland 'extremely worrying'

Available for over a year

The number of Asian hornet sightings so far this year across the UK is at a record high. There've been 22 since the beginning of 2023 - more than double the previous recorded high - with two nests destroyed on Portland and a third sighting in recent days. Worryingly, in previous years the insect has usually become more prevalent in September and October. Mark White, Dorset's Asian Hornet Coordinator, told BBC Radio Solent's Steve Harris what people need to look out for.
