Now all we need is for people to start posting links to the headline stories of "Person really does actually die after bee/wasp sting" (as opposed to "person thought they might die after spider bite" stories).
What? There are no such stories out there? Why not? It happens a lot more often than the spider bite stories do.

So effectively by condoning their presense you encourage them to breed, and that's how we ended up with grey squirrels and mink, American crayfish, and Himalyan balsam............
If you have so many in your flat, they're breeding hundreds of others.
We are an island people; we can control our borders and we can eliminate the undesirable incomers, if we work together.
Anaphylactic shock isn't a bacterial infection, but I do take Cranmere's point on the spider bite injuries.

I don't think they travelled very far from the south coast or docks though; the spread northwards is probably what has brought them to the attention of, and concern, the rest of the population.

Hornets always seemed sort of American Comic type mega wasps to us; but they're not found up here so we didn't have any other frame of reference for them.

It actually flew into his motorhome whilst he was on the 'phone to me, so I had to listen to his attempts to evict it!
The Hornets we get at home (Cambridgeshire) seem to be very shy and will fly away from you rather than buzz around you like Wasps do. I'm told that if they do sting it is no worse than a Wasp, despite their size, but wouldn't like to put it to the test.
One strange thing happened recently, I went out into the garden at about 10 o clock at night, and it was very dark, the security light came on, and within a coupe of minutes, there were 3 or 4 Hornets buzzing around the light. This surprised me at that time of night. (But as your post says, this is quite common behaviour?).
Hornets fly at night quite commonly. They regularly turn up in some numbers in moth traps, to the dismay of those emptying the trap in the morning. Up to 50 irate hornets at a time can really ruin the start to your day.
I remember Jon Pickett saying he got loads in his moth traps. He just picked them up and let them go - they are very calm creatures really (unless the nest is violated)
