A hornet nest has been discovered in Ilford, raising fresh concerns.
The yellow-legged Asian hornet nest, found six metres high in a tree, is among six recently identified across the south of England.
The British Beekeepers Association (BBKA) said it sees the invasive species as an "existential threat" to the UK’s bee population.
Diane Drinkwater, chair of the BBKA, said: "They’re all amazing pollinators and all are at risk from yellow-legged hornets which eat voraciously and indiscriminately."
The hornets, known for their distinctive yellow legs, bright orange faces, and orange abdominal bands, are capable of consuming up to 11kg of insects each year—posing a serious threat to bees, butterflies, and other pollinators.
This summer has seen a record increase in Asian hornet activity, with 24 nests already found in 2025—matching the total for the whole of 2024.
Nine nests were discovered along the south coast in June, the highest monthly total ever recorded.

The National Bee Unit, part of the Animal and Plant Health Agency (APHA), has received 68 credible sightings so far this year.
It is continuing to investigate other reports and expects to find more nests.
The BBKA is urging the public to remain vigilant and to report any suspected sightings using the Asian Hornet Watch App.
Ms Drinkwater said: "We must protect pollinators before it’s too late.
"All it takes is missing one queen and her nest for one season and we could be facing the same catastrophic problems as our European neighbours."
The yellow-legged Asian hornet (Vespa velutina) first arrived in Europe more than 20 years ago and has since spread across France, Belgium, Spain, Portugal, and Italy.
The UK is pursuing an eradication policy in England and Wales, but the BBKA warns that public awareness and quick reporting are essential to its success.
The surge in hornet numbers coincides with an increase in other insects, including wasps.
Experts believe the trend is linked to the hot and dry weather.
To raise public awareness, the BBKA will hold Yellow-legged Asian Hornet Week from September 1 to 8.
The charity has warned that even a single overlooked nest could allow the species to spread uncontrollably.
In addition to the Ilford nest, others were found in Kent and East Sussex.
The BBKA is calling on residents to familiarise themselves with the appearance of the hornet and to report any sightings immediately to help protect the UK’s pollinators.
