Further to DEFRA statement in December about Yellow Legged Hornet spring trapping, the analysis carried out by Fera Science Ltd to help inform local trapping initiatives in England has now been completed.
The work has identified areas where there may be a higher risk of overwintering Yellow Legged Hornets (YLHs), in England. It was done using data from nests destroyed in 2023 and 2024 to predict which nests in 2025 were more likely to have released reproductive drones prior to destruction in 2025.
In England in 2025, a total of 32 nests were destroyed on or after 30th September. Fera have calculated that these nests had a probability of producing reproductive drones of between 18 – 50% by that point. Therefore these areas are considered to be of higher risk.
A map highlighting the YLH nests found and destroyed in 2025 is shown below. The nests have been coloured according to their calculated risk level. There are 32 high risk nests (red), 35 medium risk nests (amber) and 95 low risk nests (green).
Further details of the nests which are considered to be high risk will be shared with the BBKA teams coordinating the spring trapping work.

As of 28/08/2025:
A change in approach to YLH sighting updates on BeeBase and Gov.uk: Since the beginning of May 2025, there have been a high number of credible sightings of yellow-legged hornets in the UK. Due to the extensive work in the field and the corresponding laboratory analysis it is not possible to provide a meaningful figure for the number of confirmed sightings as the information quickly becomes out of date as nests are found. The focus of the contingency action is on finding and destroying nests. Not all of the credible sightings will be linked to nests so until contingency action has finished, updates will only be provided on the nests found and destroyed.

Please note:
Summary of results from spring trapping for Yellow-Legged hornets in GB in 2025
A total of 22 individual Yellow-Legged Hornets (YLHs) were confirmed between January and early June 2025. Some of these hornets were captured during spring trapping led by the Animal and Plant Health Agency’s National Bee Unit (NBU) which was carried out for 8 weeks from early April 2025 to early June 2025. All these hornets were sent for further analysis.
There were 20 spring queens, one damaged individual that was likely a queen and one lone worker.
Four of the spring queens were identified as likely offspring from 2 of the nests destroyed in 2024. These were the nest destroyed in Coldred on 25th October and the nest destroyed in Udimore on 1st November. These 2 nests were themselves likely offspring of nests destroyed in 2023. This is the first evidence of a second generation of YLHs being produced in GB. None of the other 16 queens were likely related to known nests from the previous year.
Figures are included below to illustrate.

It is important to note that the numbers of second-generation hornets are very low and there have been good levels of monitoring by beekeepers and the NBU. The NBU deployed 350 traps and a total of 5,500 trap checks were made. This is not considered to be strong evidence of an established population and the NBU are continuing to take contingency action against YLH. The evidence gathered from action taken during 2025 will be reviewed overwinter.
The Tropilaelaps advisory leaflet has been updated. This leaflet explains the biology, distribution, and risks of Tropilaelaps mites; invasive brood parasites of honey bees that are now spreading toward Europe. The leaflet outlines their life cycle, harmful effects on colonies, potential pathways for introduction into the UK, and the legal responsibilities of beekeepers to prevent and report infestations. This leaflet also provides guidance on monitoring methods, contingency planning, and resources for support and compliance with UK import legislation.
Tropilaelaps monitoring advisory note: The use of waxing strips to uncap brood cells for inspection of Tropilaelaps has been widely promoted. However, the updated booklet does not contain this method. The NBU cannot endorse this practice because it is currently being reviewed by the FSA for its potential impact on food safety. Please refrain from using this technique until further guidance is issued.
In the December 2025 Bee Health Advisory Forum, Defra confirmed that they will not ask APHA’s National Bee Unit to carry out Spring trapping activity for yellow-legged hornet (YLH) in 2026. This decision has been taken in response to the high number and geographic spread of later season nest finds during 2025. Finding and destroying nests is considered to be the most effective control mechanism. Spring trapping involves looking for a small number of queen hornets in large area and is not the best way to achieve effective control. Therefore, a government-led systematic trapping programme will not be carried out in 2026.
We are working with Fera Science Limited to review the data from 2025 and supply mapping information of areas we consider to be higher risk due to the time of year nests were located and destroyed, to help inform local trapping initiatives. This information is not expected to be available until the new year. Defra remain committed to combatting this threat, and whilst there is no strong evidence of establishment, continue to support an eradication policy. APHA’s National Bee Unit stand ready to respond to reports of YLHs during 2026.
