Thank you, John, so really there is never likely to be a real problem with these Hornets when they get here any way, no different than our European Hornets with regards taking bees, so no traps of any kind will be needed, same as they are not really needed for wasps.
Edit....doubt these floor traps would catch many of them anyway if they do not go near the hives very much, never notice the European Hornets round the hives, or trying to enter them, more on the outskirts of the Apiaries, or in the back of my truck, lots of these Hornets around here, bumbles and wasps do hang around the hives though, and try and get in.
This is our second year of Asian Hornets here. Where we didn't trap in the spring ( Dismissive one of two hive owners that didn't do anything there was a major nest near) Beekeepers who trapped queens in the spring had much less of a problem.
Its Important to say that as much as The Vespa Crabbo Common European Hornet) does take a few bees, it has a major part in insect control from what we would call pest species. ( flies and mosquitos to name but a few.) and has its place in nature.
The Asian hornet will enter in to a hive, especially later in the year when hive numbers decrease and Asians are still flying. Last year i had them in to November. Mostly
We have a" Green "plastic entrance reducer, made by Nicot. which does block the passage of the Asian Hornet and also reduce stress in the colony.I dont like to use these on a flow, as it severely restricts the flow of bees and above all, traps drones. Its one of those tools , if used at the right time, its a help.
I did a couple of videos on Making traps etc. heres the link.

Chickens do a good job too!!

This is what their like, great video, Nice Narration!! and also important to point out two things, firstly, how the control specialist is in agreement with how the common hornet , shown first , isn't a general problem. and secondly the difference in nest. The common hornet very often makes nests in half a tree trunk, or cavity. Asian hornets, usually in the open, and generally much higher. this one was low , unusually!

Its only my point of view, I dont know it all. Its like everything , changes all the time. However these bottle traps do work!!!
I will be putting a minimum of 3 per apiary this year,. we've had quite a few large nests that have become visible since leaf fall, High up in the tree canopy, so those colonies have released about 60 queens in to the environment)
so Far, I think I have seen 8 on my travels in radius of about 100 km Radius and that a very low numbers. Lots have been destroyed near me, approximately 250 nests during the summer (south of Dinan here )
Can you spot this nest?this is the reality of it!! Apologies it on its side!!

The Asian hornet might well make its presence known in England in a few years, even next year, but personally , with many areas being much highly populated ( i am generalising here) I think that the control will be more effective and nests possible easier to find, with beekeepers more numerous per square mile, therefore, trapping may be more effective.
Theres also recent news, released this year to say that the drone quality of the Asian hornet, is generally poor, which is good news for their future. It was a study done in France last year.
