Asian Hornet Workshop

Held at the Bee Shed, 7th Jan 2017

Due to the possible arrival of the Asian hornet in the East Devon area in the coming year a Hornet workshop was held to bring members up to date with the latest thinking on what they can do to help their bees survive the new threat.

The NBU advocate putting up monitoring traps in late February to trap over-wintering queen hornets. At other times of the year the traps are used to reduce worker hornet numbers and ease the pressure on bees.

John Badley started off with a short resumé of the key features of the monitoring traps (see slides) followed by a quick demonstration from Colin Osborne on constructing the traps. Participants were then let loose to make their own traps.

After a break for tea and cakes Richard Simpson spoke about suitable bait for the hornet traps. In the spring the emerging queens will be looking to increase their energy stores so sweet baits are appropriate then.

Later, the worker hornets will be looking for protein to feed their brood so added fish and other proteins will make for more efficient baits. Details are given on the slides.

Hints and tips

  1. One of the best bottles we have found to make the NBU design of trap is the LIDL Lemonade bottle, or look for Buxton Water which has a distinct waist.
  2. To kill any specimens you have caught place the whole trap in a plastic bag and keep in a freezer over night. That way you don’t get stung.
  3. To make the trap less complex make one 5mm escape hole in the side and cover with duct tape if not required.
