With regards go the the dreaded Scottish midgies I spent a full Saturday evening a few weekends ago on the patio having dinner and a few beers until darkness descended.
I'm out in the countryside next to a river and the midgies are hell.
This particular Saturday had perfect midgies conditions, however I was burning 2 mosquito coils.
They stink a bit but the patio was midge free.
There was literally a 5 metre radius with not a midge to be seen.
Unfortunately I got bitten x3 when I walked around the side of the house to put my empty beer cans in the bin😠.
I've bought 4 boxes of the things now and have them stashed in the Sib / car / motorbike / caravan etc ready for deployment
