This post and those above all seem negative about dealing with hornets once they reach the hawking stage - but the extensive study identified before was not. The study did not mention use of custard so lets clarify what we might do in UK.And that's what the hard of thinking really struggle to grasp - whether it's fipronil or kill traps
Spring: hang traps to catch foundress queens if lucky, and at least random workers that indicate a nest is nearby that NBU could track and destroy. Nbu can only have finite number of inspectors and may at some time be overwhelmed by the number of calls and not arrive, in which case beekeepers might at least put an attractant on trays, covered with chicken-wire mesh to exclude birds and rats, and somehow find time to sit and watch for hornets to arrive, when they can be dabbed with fipronil custard if that has been authorised and made available safely.
Presumably the FC is rubbed off by close contact in the nest in the way OA solution is shared around bees, not activly cleaned off. Whether any is rubbed off onto the queen would be up to luck. If Qis killed, can AH rear another Q from an egg, as bees do? Ie is difference between Q and worker due to feeding, as in bees, or inherent in the egg?
The attractant would need to be something that would induce the hornets to return immediately to the nest, so not just a sweet drink. Wasps cut off the head and abdomen of bees and feed just the thorax to wasp larvae - that respond by feeding the adult wasp with a sweet solution. Do hornets do the same? If so, attractant could be bits of dried meat thorax sized - or even dried insect thoraxes. Huge new market here for bee suppliers!
Summer: AH are now attracted to bee hives, not bait, and hawk outside hive until bees cringe and stay inside. Hive entrances need to be reduced to 5mm so AH cant actually enter. Hives can be closed entirely and AH attracted to bait seeped in insecticide. Bait will be fed to larvae, so insecticide will not have to be as dangerous as fipronil for a ‘brood break’ to be acheived. But what is Q naturally fed? Do we know? She must get some form of protein as eggs cant be made from only sugar. Do Q attendants masticate incoming insect food into some special form to feed the Q? If so, then some poisoned food might be fed to the Q. Wishful thinking?
The brood break will mean no more workers emerge when all existing pupae have emerged - how long is that? Bee foragers last only 2 to 4 weeks - how long do AH flyers live? What therefore is the time period from feeding hawkers with bait to the end of hawking? Might be well into autumn? How much quicker if hawkers pick up bait seeped with a contact poison, that kills them after they have fed larvae? Ie , back to mild treatment with FC?
Please enjoy pointing out my inaccuracies. I must be word perfect for an association meeting on 15 March to prepare for action.
