It's almost time to set your traps for the wretched Asian Hornets. It's between Mid February and March/April when the Queens leave their winter underground quarters, and the traps are most effective. I believe these particular Hornets are already in the UK, so this applies to Brits also.
I read recently that traps set in Spring can reduce Hornet numbers by anywhere up to 90%.
Traps are simple to make. I use large glass jars, with a good Hornet-sized hole in the lids. I quarter fill the jar with a mix of beer, jam, sugar, and anything else sweet that's hanging around at the back of the fridge. Ours are hung in Fig and Apple trees.
These simple traps are extremely efficient; last year I must have caught hundreds, if not thousands.
I am reliably (I think) informed that in Germany one can be fined €50,000 for killing Hornets. Well, if the German Hornet Police come round here threatening to fine me, they'll feel the sharp end of my pitch fork pretty damn quick. They can pamper their own bloody pests if they wish; here we are not so keen.
I live in a major Chestnut growing area, and Bees are brought in every year to help pollinate the trees. Asian Hornets, and maybe the native ones too, kill thousands of Honey Bees annually, so the less Hornets the better; not to mention the danger they are to humans.
We want Honey Bees, not Hornets! Get setting those traps!
