In order of implementation, my plan on the arrival of the Asian hornet is as follows:

I will have left the grass to grow long in an arc in front of the hives. I do that now anyway so that I do not disturb the bees when cutting the grass.
I will have installed screens in front of the hive stands to remove hiding places under the hive and between them.
In late February/early March I will put out my spring monitoring traps near likely hibernation spots or water sources and this will NOT necessarily be in the apiary itself.
When configuring my hives for the new season I will take the opportunity to install the Apishield floors.
Early on I will identify any colonies that are weaker than others and I will unite these to get strong colonies in the summer; that will be really important.
In early summer I will begin summer trapping with traps placed around the apiary at around 1.5m in trees and in the sun; the number will be determined by seeing what the bees are doing. If they are not flying I am not catching enough hornets; simple as that.
When the hornets start hawking the hives towards the end of July and I judge the main flow is ending I will drop the entrance restrictors and install the muzzles.
When I have identified the hornets’ flight path I will deploy the harpe electrique and I will be putting sticky traps under the hives.
I will time my inspections to avoid mid-day, favouring early evening.
As hawking intensifies I will install additional non-selective inner traps at entrance level just in front but to the side of the entrances.
At peak predation I will introduce Veto Pharma traps on top of and behind the hives and I will feed the bees.
In October, I will ensure the bait is appropriate for autumn trapping of sexuals.
