A team of exterminators were taken to the site by Le Mourier Marine aboard their charter Princess 45 Flybridge yacht, Amour Toujours. The nest, which was on an overhang 15 metres above the sea, was spotted by a group of kayakers.
The exterminators used an extendable pole to spray the nest with pesticides.
Last month, Alastair Christie, Jersey’s Asian hornet co-ordinator, said the fighter against the invasive species was entering a ‘critical phase’.
‘Towards the end of the summer and early autumn the nests start to produce drones, which are the males, and the nests also produce virgin queens.
‘Once the virgin queens start to leave the nests and are mated by the drones, we are moving into a position that is directly related to what will happen the following year, as the queens will hibernate and, if they survive, go off to produce a nest in the spring.’
He added: ‘Each nest produces about 200 to 300 virgin queens. The death rate is very high, but if 5% or 10% of the mated queens survive the winter, then quite a few nests will be created next year by the queens emerging now.
‘We are therefore in a critical phase in the fight against Asian hornets. It is very important that we find the existing nests and destroy them as soon as possible.’
The species, which began to spread through Europe in 2004 after arriving in the south of France inside a freight ship, was first spotted in Jersey in late 2016 and the number of nests has been growing year on year.
The invasive insects prey on bees – eating as many as 50 a day – and are considered a threat to other pollinators.
