Entrance block or not?

Read an article in Beecraft earlier and now think I know why the bees took offence to me cutting the grass the other day and had never before.

A couple of weeks ago I was watching the bees going in and out and could see there was a bit of a bottle neck going through the reduced entrance that the entrance block creates, I thought if they could go in and out quicker I would get more honey?

But I think what happened was that the bees got uncomfortable with the wider entrance to guard. They have to guard the entrance because other bees and wasps will rob honey from other colonies, I have often seen bees fighting with wasps at the entrance. Bees are also creatures of habit and they don't like change. The end result is that I think I made them a bit more aggressive and the lawn mower tipped them over the edge.

Yesterday evening I popped out and put the entrance block back in, hopefully they will feel a bit better and I can cut the grass again at a reasonable hour of the day! Time will tell.

PS Just noticed that I have posted over 100 posts, so a little bit of a milestone :-)
