I have never had any problems at all with fly spray...until recently. My husband bought a little thing of Farnam roll on repelent for our donkey who hates being sprayed. I used it on my mare as I hadn't bought her any spray yet. I put it on her face, a couple stripes down each leg, a stripe on her shoulder, etc. right before a ride. Well something came up and I didn't get to ride. I untacked Lenore and left her in her dry lot for the evening. When I went out to feed later that night I didn't notice anything funny, but it was dark, and I was in a hurry. The next morning Lenore had huge welts everywhere the roll on had touched her, the skin being raised everywhere in the exact shape of the mark where I had put the repelent. I immediately scrubbed her down with slightly soapy water and kept an eye on her. She seemed fine other than that. The welts went away...or so I thought. The next day I was gone most of the day helping my brother move. When I got home late that afternoon and went to turn the girls out I immediately saw something was not right with Lenore. She was panting despite just standing around in her stall, her nose running. I could see her pulse jerking the flesh on her chest and she seemed oddly puffy everywhere. She had rubbed a spot on her chest/neck raw and places where I had put the repelent on her legs were raw and blistery, oozing. I had the vet out on an emergency call and, as I was suspecting, Lenore was having a terrible allergic reaction to the roll on. The welts hadn't actually gone away like I thought, the rest of Lenore's skin just puffed up around them. I felt horrible for not seeing is sooner, but other than the welts she had seemed fine the day before. The vet got her all fixed up thought and she is fine now.
I have since been using Absorbine Bug Block on her and she is doing fine with it. That was a scary expierence though. I had no idea she would be allergic as I have used plenty of fly spray on her before.
