The Asian Hornet, Vespa velutina, is an aggressive predator of honey bees and other beneficial insects. It has extended its geographical range from Asia to mainland Europe following an accidental introduction to France, is now also present in Spain, Belgium, Portugal and Italy and now the UK.

Adult hornets are highly mobile; the rate of spread across France is approximately 100 km/year.

Hanging a simple trap in your apiary will allow you to monitor for pest arrival and, if necessary, help to protect your colonies from attack. These are especially effective if used in spring.

Reports from France suggest that in areas where spring trapping has been used, subsequent numbers of Asian hornet nests are reduced by as much as 97% (2 or 3 nests in trapping areas versus >70 nests where no traps have been hung).

Following advice from the NBU, we are organising a trap making workshop 14 Sidney Road, CV22 5LB on the morning of Saturday 11th February 10.30am - 12.30am.

Required materials:

– One (or two if you can) 2 litre plastic bottle - ridged ones obtained from Asda or any bottle with the bottom slightly larger than the middle section.

We will provide :
– plastic coated garden wire
– 100mm square off-cut of wire mesh
– sharp knife, wire snips or Stanley blade
– scissors

On the day we will assemble one trap together following the NBU guidance, and you can make more at home if you wish.
