Don't have much in the way of options really. It is illegal to catch and release AH (so if one ends up in your trap you have to leave it there).how many, on finding velutina in their traps would kill them and then call the AH team?
Have a look at the jersey Asian Hornet group on Facebook. There is an endless parade of nests destroyed but somewhere in there is their method. Fascinating. AH don’t forage far from their nests which helps.
Triangulation usually. You don't need the complete flight path, just the general direction.
Thank you for the explanation.Telemetry is useful but is now generally reserved for research tracking purposes as it can be expensive/haphazard.
Hornets chew off the transmitters when they return to the nest so new ones need applying.
Also transmitters fall off. Many reports of AH nest tracked to a low bush only to find it is a detached transmitter.
Triangulation is cheap and easy.
Removed a few when I was living in France - one on my land 50m from my hives. Nests always way up in tall trees - which is not even an option on this quizThis being Asian Hornet Awareness Week, is very timely if anyone has a bit of time and would like to volunteer help with their local AH Teams.
There is a short quiz/exercise here for anybody who wants to check their knowledge about AH. Completion of the quiz and registration gives you extra insurance when out locating nests (separate from BDI ).
The quiz itself is extremely simple (it won't let you proceed until you pick the correct multi-choice answer) but it's still very useful.
