WITH reference to your articleon trapping Asian hornets, we gave up on traps when we realised how many moths, beetles and butterflies go for them. When our trap killed a scarce swallowtail, that was it.
As a former beekeeper, I can sympathise enormously but non-discriminatory insect traps should not be used unless they come up with an awful lot of hornet corpses and very little collateral damage or by-kill.
The only effective method of dealing with Asian hornets is nest destruction, by professionals. Look now, especially near beehives, before the leaves grow back on the trees.
