Somerset BKA's Asian hornet action team co-ordinator Lynne Ingram is urging us all to start monitoring for Asian hornets:
"We're approaching the time when Asian hornet queens will be emerging from hibernation – when the temperature is consistently reaching 13 deg C – and so we need to be monitoring for their presence.
We don’t know if there are any Asian hornet queens over-wintering in the UK this year, or whether any mated queens will make their way into the UK post-hibernation. But we need to be prepared.
We strongly recommend the use of monitoring stations, rather than killing traps. This allows us to get the evidence of Asian hornets that we need, without killing our native beneficial insects, in particular European hornets.
Asian hornet queens will be searching for sugary foods to build up their energy, not preying on your bees. This means that all monitoring stations need to be positioned where you cannot help but see them and where you can easily check them daily - e.g. outside the kitchen window, or in a sunny spot in your garden. All beneficial insects must be released from monitoring stations daily.
From mid-May Asian hornet queens will be mainly in their nests and so monitoring stations can be removed.
We are recommending the adaptation of Thorne's traps to include the wick stations inside. This allows wasps and small flies to escape. (See photos above).
Use Suterra (now sold as Trappit wasp attractant). Get this from your AHAT Team leader if restrictions allow (keep yourself and others safe and comply with government guidelines) or buy online (Pestfix.co.uk sells smaller bottles).
If you cannot get it due to current restrictions try one of these French recipes:
• Dark beer mixed with 25ml strawberry dessert sauce and 25ml orange liqueur
• 350ml sweet white wine (or white wine sweetened with sugar) + 20-30ml mint syrup
Please also observe any flowers where Asian hornet queens may be feeding. Any trees that may be oozing sap are also very attractive to queens in Spring. Being confined to our homes at the moment gives us the ideal opportunity to spend time monitoring for Asian hornets.
From the August onwards, Asian hornet workers may be found preying on your bees, so monitoring stations may also be hung in your apiaries. Again, we need to be monitoring regularly so that we protect our beneficial insects, and so that we have live samples that could be tracked if necessary. Please register your monitoring stations in apiaries on BeeBase.
What to use
• Monitoring stations as above
• Open bait stations – plastic tray with screwed up kitchen roll, a stone and your liquid bait. Ideally protect these from rain - on a bird table
In the Autumn Asian hornet workers can be observed on fallen and growing fruit and on ivy plants, where they will often be seen taking prey. Males and new queens will be produced in the late Autumn and males can be seen feeding on flowers. This is a crucial time to spot Asian Hornets as it is important to find any nests before the queens emerge and go into hibernation. Observe plants, fruit and also around your apiary.
If you think you have seen an Asian Hornet:
• Get a photo (or sample)
• If you are not sure or are struggling to get evidence contact your local Asian Hornet Action Team – firstname.lastname@example.org
• If you are sure and you have evidence, then report on the Asian Hornet Watch App or on email@example.com – and to your local AHAT.
Due to current restrictions please make sure that you keep yourself safe and comply with government guidelines. Check BBKA website for updates on how this relates to beekeepers."
