That made me think about the size differences, don't see many hornets at all where I am. I found the attached on the web courtesy of Isle of Wight - Asian Hornet Watch.

I haven't see many European Hornets my way this year - a dozen maybe. They're impressively big! I also noticed that they're really not a threat to my hives as in spite of hanging around trying to catch a free meal, they're not gifted flyers compared to the Asian Hornets. This season, on a good / bad day, I've trapped 40 Asian Hornets.

Long may you go without encountering them in your neck of the woods.

Hi Richard do you know what the optimum height aperture should be for bees ? Im guessing about 5mm? Im wondering if this will keep out the Asian Hornets?I'm worried it will trap the drones however.

As I understand it only young (hence smaller) Asian Hornets can get through a gap of 5.5/6mm. I've personally not yet seen it happen. At 5mm I'd have thought you'd be safe but I can't say for certain. Yes it will trap drones. Everybody says they will be kicked out of the hive any time soon but I don't know....a guy not far from me had them at Christmas time last year! Anyhow, it's the price for stopping hornet intrusions. I suspect the hornets will be gone in a couple of weeks and then you can increase the space to let drones freely move around.

Asian hornets hawk at the entrance surely? By the time they are invading the hive the colony is knackered

In general absolutely. But you do get the occasional one going in. I've noticed as the season has progressed they've also progressed from hovering in front to increasingly landing and the odd one entering. Maybe they're testing it out to see how strong it is? If you get several going in simultaneously I imagine it's safe to say the colony is doomed. I've recovered a few dead Asian hornets from inside the hives over the last month.

I,m not sure that is the case Dani. My bees seem very active the hornets are opportunists and the beer and grenadine seems to have been very effective in culling them.I've also seen my bees kicking dead hornets out of the hive.

Im really hoping this is not the case. Ive seen the behaviour of my bees change over the past few weeks, but I've put this down to the change in the weather. Short of camping outside the entrance of the hive Ive been very vigilant with the hornets so Im praying they survive. I need to have a look inside the hive I guess if we have a freakish warm day. Ill try and see whats going on.

If you've changed the entrance and put a couple of traps out by the hive there's nothing else you can do. Either they're OK or they're not (they probably are...). Are there bees coming and going when the sun shines?

Yes they're normally active when the sun comes out and Ive banged the hive a few times and they react in defence.

Hi Will when was the last time hive was inspected? Why not crack the crown board and look.

I've been thinking that, I want to wait for a sunny day. The first time I looked in the hive was on the 23rd October. The frames looked very healthy and full of honey even though I only got the bees in late April.Not being an expert the experience was quite overwhelming the bees where quite active and I wasn't really sure what I was supposed to be looking for. I was surprised at the ferocity of them and also the number of them.

They have despatched a hornet I saw them drag a dead one out of the hive.My bees are fierce. I used smoke on them when I opened the hive and they were certainly not docile.
