28.10.16

This morning we successfully removed the Asian hornet's nest and destroyed the contents.

75% of the intact nest has been frozen, we hoped of a better amount, the majority of the nest is undamaged.

We had a sheet present underneath which collected other falling debris, hornets and larvae - we managed to get this into a bag so in all we have about 90% of the nest.

 

The nest has been frozen to -20 degrees and triple bagged and is located at our abattoir at kiln farm Alderney awaiting examination.

There are issues with shipping hazardous good off island so the organisation of having people to come here to examine the nest is being taken care of at the moment. Examination of the nest on island will allow the relevant people to look at the location at which the nest was destroyed.

Conclusion:

Continuous surveying by the bee keepers is ongoing and they have my contact details to alert me to any situations they have, or any nests that they may discover. Once the leaves have come down from the trees I am going to search for more of the nests.

The preparation and execution of the operation was successful and this method will be one we are using again when presented with the difficulty of areas being inaccessible by vehicles. Where vehicles can be used they will be but the administering of the poison and the safety measures taken will remain the same.
