I’m hoping some of our ‘cousins’ that live in the warmer and more humid environments, might have some recommendations for insect repellents and bite treatment.

We are just at the beginning of our summer here in England, and I’m hoping to get through without too many bites.
We don’t have many really nasty critters here, but, as my wife and I spend most of the day and quite a few evenings in the garden any advice would be most welcome.
Thanks, in advance.
