There are always occasions when the needs of humans are more important than those of insects or animals. Now I will be trolled!!
Last summer we had bees nesting between the interior lining and outer cladding of our garden shed. I first noticed them when they attacked me and chased me halfway down the garden. After that I could not get within 20 foot of the shed, which is large,contains the stock of our small antiques business and DH's work area and a lot of my vegtable garden
I spent hours googling to see if there was any way I could move them on, I then googled all the local pest removers until I found one who was overtly pro bee, who agreed to come and look. After he was mobbed by bees before he got anywhere near the nest. He agreed this was an exception to the rules and the only thing to do was to destroy it. And he did.
Absgran you are in exactly the same position as I was, in this case it is your health at risk. Get someone in to destroy it.
As for the plea for the wasp. I was listening to a R4 program this week about wasps. What are described as 'yellow jackets' are only a tiny proportion of all the different types of wasps around, most of whom we do not notice because they have different behaviours and neither nest near nor bother humans.
We were parked for a while in a country layby yesterday and I was looking into the hedgerow and saw a mass of insepcts around one type of plant. When I looked closely I realised they were very small wasps. I was looking at a myriad number of the wasps that go about their pollination business and bother no-one.
Clearing a dangerous wasp's nest like will do little or no damage to the number of wasps around busy playing their part in the world ecosystem.
