Note that this is a fairly long letter with a number of varied topics relating to the hornet. I have italicised the various headings in the letter, and point out that the final item is describing the new method of monitoring. I hope that this will help and encourage you to read it all.
National news
The numbers of YLH insect and nest sightings being confirmed weekly by APHA and communicated to YLH coordinators continues to rise rapidly week on weekAs of 28th August, there have been 342 credible YLH sightings, and 86 confirmed nests. The newest nests discovered have been in:
London: Ilford, Barkingside
Kent: Stonecrouch, Ashford, Exted, Wingham, Thanington, Lenham, Wittersham
Surrey: Holmbury St. Mary
East Sussex: Udimore, Fouroaks,
The first nest has been confirmed in Cork, Rep. of Ireland.
42025 Already has the highest number of sightings and nests and the “crunch” weeks of sexual gyne production are likely happening now and for only a few weeks more.
This week (w/c 1st September) is Yellow-legged Asian Hornet Week, there is a lot of activity planned for both beekeepers and the general public
NBU Update:
There will be an update from Peter Davies, Operational Delivery Lead and an APHA Science Blog will be released during the week.
Zoom Talk by Andrew Durham:
Yellow-legged Asian Hornet – Is Nest Destruction a Dangerous Delusion? Is Spring Trapping the Lesser of Two Evils? – Wednesday 3rd September 7.30pm
Andrew is a Cambridgeshire beekeeper who started his research into the yellow-legged Hornet in 2014, travelling around France and researching the impact of the hornet on French beekeeping.
The talk: as the hornet continues to make ground on the continent and is threatening to get established in mainland UK, this is an important and timely contribution to a debate that beekeepers are going to have to have before the NBU withdraws from the front-line battle to eradicate the hornet. Beekeepers on the continent are getting drawn into the general fight against the hornet and are being overwhelmed. Andrew examines the pros and cons of the different schemes in operation in France (and Jersey) and he suggests how beekeepers could best use their limited resources to serve their bees.

Yellow Sock Day, Friday September 5th:
The idea behind ‘Yellow Sock Day’ is to wear yellow socks to emphasize ‘yellow legs’ as a key identifier of Yellow-legged Asian Hornet. The BBKA want to help build public engagement, improve identification and raise awareness in a fun way. Please take a photo of yourself wearing yellow socks and share it on social media tagging the BBKA: #BBKA and #YellowLeggedHornets BBKA Trustee, Luke Whyatt, (and some Accompanying YLH coordinators you may recognise) will also be visiting various London landmarks on Monday 1st September wearing the Yellow- legged Asian Hornet costume to help raise public awareness.
Surrey County News.
You will have seen from the list above that Surrey now has its first nest in 2025. I am relieved that it was found 3 days after being reported and was destroyed within the week. It will be some months before the analysis confirms if the nest was mature enough to have released sexually mature hornets.
What concerns me more is the apparent isolation of Holmbury St. Mary relative to where we thought the “front line” was, with no obvious adjacency to a transport route or hub. This means we need to further increase our efforts to both raise awareness of identification and reporting amongst the public AND do more monitoring.
Let’s use Asian hornet week (1-7 Sept) to encourage every Surrey resident to be our eyes looking for hornets, YOU can help raise awareness by
• taking an active and visible part in Asian Hornet Week by following and reposting @britishbeekeepers posts regarding Yellow-legged Hornets on social media.
• wearing knee high yellow socks or wellies on Friday the 5th of September, which will be “Yellow Socks Day”
Create your own social media posts, share BBKA or your own association posts focusing on
- how to recognise Yellow-legged Hornets from other insects
- how to report them using the Asian Hornet Watch Free App. See it! Snap it! App it!
- The need to check vehicles and luggage for unwanted stowaways when travelling home from Continental Europe, the Channel Islands or the South and South East coasts of England.
Our new approach to monitoring is less “bait hungry” than previously. The NBU now advise to put wick monitoring pots / open bait trays out for 2 – 3 days so that Hornets find them, then only put them out for up to an hour and watch them while they are out.
This takes advantage of the hornet’s tendency to fly foraging circuits, so once they have found your bait they will return if they are in the area. However, as we keep taking them in when we can’t actively observe them, we will not use up as much bait as we have in previous years.
The important thing is to have a broad spread across a whole division’s area – so please if you can help, please talk to your YLH coordinator and join the monitoring programme. We will all feel a lot calmer heaving a sigh of relief in October, when we have found nothing more.
Once again, if you have not done so already- please download the Asian hornet watch app and encourage everyone you know to do so as well. The NBU will not attend unless or until they have a photograph to support a report, so it is best that we are all prepared to jump to the correct action as soon as we think we see an invading hornet.
LAST BIG Show for Public Awareness Raising
Finally- early date for your diary. We have space for more YLH awareness raising activity at The Ardingly Autumn Show.
• When? Saturday 27th and Sunday 28th of September
• Time? Chose a slot 9am – 1:30pm: 11 – 3:30pm; 2 – 6:30pm
• Where? Ardingly Show ground, Haywards Heath RH17 6TL
You get free parking and entry to the show so it’s a great way of enjoying 5 hours or so at the show for “spending” 4 hours talking about YLH in the Honey Pavillion to the public and meeting beekeepers from across Kent and Sussex.
Please contact Helen on YLHlead@epsombeekeepers.co.uk to agree the slot(s) you can cover.
More details below.
Helen Worwood (Surrey YLHT Co-ordinator)
Help run Yellow-legged Hornet awareness stand at South of England Showground, Ardingly
Saturday 27th & Sunday 28th September
The South of England Autumn Show is rapidly approaching. A great weekend (Sat 27th and Sun 28th September) to enjoy and variety of countryside sports, displays, and “have a go” activities, all aimed at celebrating the joys of rural life and equestrian pursuits. The Show features a non-stop programme of agricultural and equestrian displays, country pursuits, live entertainment, rural crafts and an abundance of food, drink and shopping opportunities.
Surrey YLHT have secured a stand in the pavilion alongside he South of England honey show to raise awareness of the Yellow-legged Hornet. Croydon and Reigate beekeepers will lead on organising our presence at the event (tables, banners etc) but are appealing for additional volunteers from across Surrey to talk to the public about the risks the hornet presents and to hand out flyers
The show is open 9am to 6:30pm each day. If you have a few hours free that day we would particularly like help covering the following shifts
9am – 1:30am: (Set up on day1) and shift 1
11:00am – 3:30pm shift 2
2:0pm – 6:30pm shift 3 (Pack away on last day)
If you are free, please email YLHlead@epsombeekeepers.co.uk indicating which dates (Sat 27th or Sun 28th) and shift(s) you can cover.
Helping out gets you a free pass to the show and parking in the free “helpers” carpark. You are, of course, free to fully enjoy the show when not on shift at our stall.
I look forward to meeting many of you there.
Monitoring for the Presence of Yellow Legged (Asian) Hornet
A Surrey Beekeepers Association Initiative – Summer 2025
Working together to keep Surrey free of this Invasive Predator
The Yellow-Legged Hornet (YLH, Vespa velutina nigrithorax), sometimes referred to as the Asian hornet, is not yet established in the UK. However, recent credible sightings in Kent, Sussex,
Hampshire — and now Surrey — show the threat is very close. The National Bee Unit (NBU) can only investigate credible reports, which must include a clear photograph of the suspect insect. It is vital that we can all recognise the Yellow Legged hornet and report sightings quickly.
Your help could make the difference in keeping Surrey free from this invasive predator.
The simplest and safest tool to use is a home-made wick bait station as this gives you the opportunity to monitor the insect(s) and to take pictures. The wick pot does not trap insects and so there is no insect by-catch to release.
Hornets fly circuits repeatedly returning to the same food source so once they have found your wick pot they will return, this behaviour enables us to take photos – just be patient for the hornet to return. The equipment required to make a bait station is very straight forward: a jam jar with its lid, a disposable kitchen cloth, and the bait liquid.
Editor’s note: This is not a ‘trap’, i.e. it will not ‘catch’ a hornet. Its purpose is to see if there are hornets in your area.
To make your own wick pot.
1. Prepare the Jar and Lid
Make a hole in the lid of the jar. The hole should be under 1cm diameter.
To make the hole, use a pointed item such as a countersink/chamfer drill bit, position it in the middle of the lid and tap it using a hammer, shape is not important. To protect your fingers, flatten any sharp metal edges on the inside using the hammer.
2. Prepare the Kitchen Cloth Roll a piece of kitchen cloth into a tube and fit it through the hole in the lid. It needs to be snug and extend to reach both the bottom of jar and 2 –3cm out of the lid.
3. Add the Bait Liquid to the Bait Station
Fill the jar with wasp bait to a depth of about 3cm. Shake the jar so the cloth is fully wet with the bait liquid. Wasp bait can be purchased at garden stores or obtained from your Beekeeping Association.
Put the wick pot outside
Leave the wick pot where you can easily see it.
Action to take if a YLH comes to feed
You can approach close to the bait station with little risk as the insects are very focused on feeding but do not poke them and try to can easily see it from a window, ideally in a sunny position. Consider putting it undercover as rain will dilute the bait. Initially it may take 2 –3 days for the hornets to find it during a circuit flight. Once they have found it you only need to put it outside for about an hour while you can monitor it.
You may find that visiting wasps and European hornets nibble the cloth and shorten it. If you allow a longer length inside the jar, then you can pull more cloth upwards through the lid instead of having to replace the whole cloth.
The bait will get used up after a few hours. To conserve it, only put the wick pot out when you can monitor it, at other times put it away avoid standing in their line of flight.
Take a photograph of the insect – zoom in as close as your camera allows. Key features to see and photograph are yellow legs and yellow abdominal segment.
Use the Asian Hornet Watch App to report your sighting. Download the app and follow the in app instructions to give location and don’t forget to attach the photograph!
Pictures and locations are essential information for the sighting to be treated as credible.
Surrey Beekeepers long-term YLH Monitoring Plan
Our aim is to keep the YLH from becoming established in Surrey. To support the NBU eradication plan we need lots of monitoring across the whole of Surrey. Our long-term goal is one wick pot per km². Every volunteer helps us get closer to county wide coverage.
We need as many volunteers as possible to become involved in monitoring in bursts of 1 week between spring and autumn, driven by sightings and prevailing weather conditions.
To get involved contact
NAME of local YLH lead:
EMAIL of YLH Lead:
with the following information:
1. The location that you can monitor a wick pot, preferably a what3words reference or a postcode

Tiny transmitters on Asian Hornets a game-changer
I am picking up that many are aware of this new device. For those who have not heard about it, the following is a quotation from a report accessible via Google:
‘Tracy Wilson, from the Animal & Plant Health Agency (APHA), called the new trackers “game- changers” in their work and said the speed at which nests could now be found would mean resources were freed up to find more nests. Dan Etheridge, from the National Bee Unit, has been experimenting with the transmitters in the UK over the past week.
“We’ve already used six tags and we’ve found six nests, so it’s going to speed things up dramatically for what we do in the field,” he said. ’You can access the report by feeding into Google asian hornet tracker
Thanks to those who have made us aware of this device.
