Auckland Intensifies Fight Against Invasive Yellow-Legged Hornet

Authorities in Auckland have intensified efforts to eradicate the invasive yellow-legged hornet following the detection of 27 queen hornets in the region. This surge in hornet sightings includes seven workers and 17 nests that have been discovered and removed from the Glenfield and Birkdale areas. The first hornet was spotted in Glenfield in late October, prompting immediate action due to the species’ potential threat to local ecosystems, particularly to honey bees and wild bees, which are crucial pollinators.

Genetic testing indicates that the hornets belong to a “small, contained population,” reducing concerns of a widespread infestation. According to Mike Inglis, commissioner of Biosecurity New Zealand North, the findings demonstrate that surveillance measures are working effectively. This has led to an expanded search across Auckland’s North Shore, as reported by 1News.

Enhanced Surveillance and Community Involvement

Inglis noted that in recent weeks, authorities have deployed five times as many traps, increasing the total to over 600, within a 5-kilometre radius from detection sites. Property-by-property searches are ongoing within 200 metres of confirmed sightings. As of now, teams have inspected more than 2,100 properties, with numbers rising daily.

“The ground searches are paying dividends,” Inglis stated, as many nests and queens have been detected through these intensive efforts. The response operation involves collaboration between Auckland Council, Pest Free Kaipātiki, Plant & Food Research, and Kiwifruit Vine Health, in partnership with Biosecurity New Zealand. Additionally, electronic tracking equipment sourced from international expertise has arrived to bolster these efforts.

Community Engagement and Public Notifications

Inglis emphasized the importance of community involvement in this eradication effort. More than 4,000 public notifications have been made, showcasing the community’s significant contribution to the campaign. “We’re very keen for this to continue,” he added, highlighting the value of public vigilance in identifying potential hornet nests.

Residents who encounter a suspected hornet nest or possess photographic evidence are urged to contact Biosecurity New Zealand promptly. This collaborative approach aims to safeguard local ecosystems and protect essential pollinators from the threats posed by the yellow-legged hornet. The ongoing efforts are crucial in maintaining the ecological balance in Auckland and ensuring the health of its bee populations.
