I hear you! I have tried a bunch of things too. It seems the older I get, the worse I react to them too. I tried afterbite, baking powder, scratching, not scratching etc. etc. etc. I cover as much as possible and if I have to work out in the grass I wear a hat with the screen ($ store has them) this time of year in the garden section. I was watching the news and they said it is going to be a record tick season as well.
