Has anyone else tried Calamine lotion for bug bites? I discovered it keeps the flies off an open area and stops the irritation. The last two years my horse has been on anti-histamines and steroids to deal with a severe reaction to bug bites. She gets bitten around her bag and inner back legs where there is no hair. Year before last she swelled right down to her hocks and walking seemed to cause a lot of discomfort. This year I started putting Calamine lotion on the bites and it seemed to help. Now I'm painting a thin layer on all the skin around her bag that doesn't have hair...and it seems to be working like a charm.
