Hi,
So yes....it sucks.
I'm currently sat in the garden with a rain mac on...in 24 degree heat 👍 in the hopes that the waterproof material won't be penetrable. Also socks tucked into trousers, so at least I'm looking good 😳
I always get bad reactions to mosquito bites, especially on my feet, but normally when I cover up, it's ok. Also, shit loads of DEET. But tbh, I don't like using chemicals as strong and controversial as that.
Anyway, sat out last night and I could hear them buzzing around, so put on socks and a cardigan. The bastards bit me through the cardigan AND my top!! 
When you Google, it says vast majority can't penetrate most fabrics, so these must be monsters! I've seen them and they are enormous.
I understand that some people are more tasty to them, but this is more like some kind of mutant breed!
I'm in the UK, but where we are are lots of rivers, so no escape really.
Anyone else feel my pain....literally?!
