Asian hornet nest discovered in Torteval
Friday 08 September 2017

An Asian hornet nest has been discovered in Torteval.

The nest is in a Sycamore tree approximately 9m above ground level, and is estimated to measure approximately 30cm across. The nest has been treated with a powder insecticide this afternoon by a professional pest controller. It will be removed from the tree shortly once the pesticide has killed any live hornets. Once removed, the nest will be bagged and frozen to kill any remaining unhatched larvae.

To protect public safety, the location of the nest will not be disclosed until after it has been removed, as hornets may be aggressive if disturbed.

The discovery was made by Damian Harris, a local bee keeper, and has been verified by Agriculture, Countryside and Land Management Services (ACLMS). Mr Harris said:

"As it was too overcast and showery to do anything with my bee hives, I decided it would be a perfect opportunity to go out for a walk and see if I could see any Asian hornets flying around the area of Torteval where insects have been sighted. I have a lot of bee hives on the island and it is in my interest to prevent the spread of the Asian hornet.

I wandered the lanes with my binoculars looking for anything large that could be hornets and mainly by luck saw a large egg shaped object in a tree and knew at once that this was a hornet nest. The hornets were out wandering over the surface of the nest and flying in and out.

I'm very relieved to have found it as a beekeeper and will continue looking for nests at other potential sites."

Agriculture, Countryside and Land Management Services wishes to thank members of the public and the Guernsey Beekeepers Association for their assistance with hornet sightings so far, which have played a vital role in the discovery of the nest.

The public are asked to remain vigilant, as information gathered so far indicates that at least one further nest is likely present in the southwest of the island (Torteval, St Saviour's, St Peter's) and also a nest in the Vale in the vicinity of Bordeaux and the Bridge.

It is important that any nests are found as soon as possible. Queen hornets will shortly be leaving the nest to overwinter and any queens which survive the winter will go on to build new nests next year.

Anyone finding an Asian hornet is asked to photograph the insect if possible, note the location and watch it long enough to determine the direction of travel as this may be helpful in finding a nest site.

Information about the Asian hornet and Asian hornet nests is available from the National Bee Unit's website: http://www.nationalbeeunit.com/index.cfm?pageid=208 (paper copies available from Raymond Falla House). There is a short video clip of an Asian hornet on gov.gg/asianhornet as well as downloadable PDF documents which highlight the differences between the Asian hornet and other similar looking species.

Sightings should be reported to Agriculture, Countryside and Land Management Services, Raymond Falla House by emailing aclms@gov.gg or telephoning: 01481 234567. Sightings can also be reported through the 'Asian Hornet Watch' app, which is free to download from the App Store. Any sightings in Alderney and Sark should be reported to the States of Alderney or Sark Government offices.

NEWS UPDATE 27th July 2017

Dear Members,

Well its happened the news I hoped I would not have to pass on to you but knew that inevitably I would.

Three Asian Hornets, what I believe to be female workers were caught yesterday at a property within about one hundred meters of the Torteval church and a an abandoned embryo nest of approx 4cm x 6cm was cleared by the states from a property adjacent to the church. It was discovered in a Wendy house.

The workers were caught foraging on I believe aphids on a willow so this indicates they have young to feed as they are seeking protein

The nest found was the embryo nest that the queen builds raising a few workers who then abandon this to build the larger nest high in the tree canopy nearby.

There will be a nest in the early stages of development in this area

Members who have bees in this area are being organised to look for this nest which will probably at this stage be difficult to find.

We must not let up our search as should this nest not be found and produces Queens to overwinter then we will have a very big problem next year.

So please check and refresh your traps and add the protein element such as cat meat, prawns, mashed fish etc as an encouragement. Meat, fish etc will probably need to be replaced every few days. Don’t abandon the sweet liquid entirely as the hornet gets its reward from the larvae when it returns with mashed up insects but better still if it continues to get it in your trap.

The French cocktail used in traps is Biere Brune, vin blanc, Crème de Cassis or Sirop de cassis in the ratio of 2:1:.02 (500ml:250m:l50ml. Use a Ruby beer but not light ales, bitter or stout. Avoid beers with hops and burnt malt. Biere Brune is a strong sweet malt beer but whether it is available in Guernsey I am not sure.

Also be vigilant and alert your neighbours and friends to the possibility of there being more hornets around the island. If they can reach Torteval they can be developing nests anywhere.



Dear Members,

By now some of you will have stopped maintaining your hornet traps having not seen any Hornet Queens through the spring but we must not allow our defences to be lowered.
It may well be that there are no hornets in the island but there just as well could be and we must maintain our guard.
In the early part of the year hornet queens build embryo nests close to ground level which reach the size of a small football. It was one of these that was found in Jersey last week and in an outhouse in Alderney last year. Workers then start the construction of a larger nest high up in trees hidden by the leaf cover and which don't show themselves until leaf fall. By then it is too late as they will have released lots of queens to hibernate over the winter.
Just Saturday afternoon a sighting was made in Sark and from the photos placed on Facebook it certainly looks like an Asian hornet.
The hornet was seen on flowers so would have been taking nectar and may not yet have a nest started so both the sweet and protein bait should be made available to them.
So we must maintain our guard and the best way we can do this is by maintaining the traps, being vigilant and if one is spotted try to capture and kill it in the freezer.
Traps may well need replenishing with proteins now if any hornets have established a nest and are feeding young they will be looking for meats.
As a refresher I attach bate instructions provided earlier in the year for your information.

Preparation of the Asian Hornet attractant

The contents of each sachet is a concentrated preparation based on plant extracts and natural ingredients. It is manufactured by Véto-pharma

Caution: The contents contain ethanol.
Keep out of the reach of children. Do not swallow Store in a dry place at room temperature.

Contents of sachet- Purified water, Ethanol, Plant extracts and natural ingredients,


1-Mix the contents of the sachet with 200cc of water and 50g of sugar.
2-Add the mixture to the trap and position in an open location, where it will be found by the hornets.

The attractant will lose its effectiveness after 3-4 weeks and needs to be replaced.

Hornet queens are looking for carbohydrates in early spring so the sweetness of the attractant is important

Other attractants that can be used in the spring and summer are Wine, vinegar and cassis Dark beer, sugar, Blackcurrant syrup Sweet Apple juice

Later on in July onwards sardine or shrimp or cat food will attract workers if nests become established

Just a couple of photos as a reminder of what they look like

These are my Mark 2 Asian Hornet trap. Exactly the same as before but now the bottom of the bottle is not cut.
Before inverting the neck some foam rubber or sponge is pushed to the bottom onto that I have placed the mesh. This will prevent any insects from drowning the 5.5 mm holes near the top allow other insects to escape. The top cover is a shop bought trifle container.
The sponge absorbs the bate and provides a support for the mesh if added but not necessary as long as the foam is higher than the liquid.
These will be a lot easier to make.
