Farnam MosquitoHalt Insect and Pest Repellent Spray for Horses

If you've done horse stuff for any amount of time you know there are 'seasons' where nothing seems to work. I'm from Nebraska. 2 years ago, went to a show in Wisconson and equine eating critters of unknown entymology were sending my thin skinned fainting goat diva OTTB out of his walnut-sized brain [brave eventer - HA!]. Wisconsin-ites scoffed at my chosen fly control and said, 'we have real bug problems up here, and THIS [Mosquito-Halt] is what we use'. I bought 2 from the show vendor and here I am 2 years later still using it. That being said,....folks get real about fly spray. I see people applying it like perfume before going to the opera!. We had the 'bomb cyclone' in March and the whole state remains a large puddle and a mosquito & fly breeding ground. July & August in 'normal years', I find myself using 2 fly spray products regularly- AT THE SAME TIME!! Usually and herbal and a chemical. They BOTH get applied just after grooming and then again right before I get on. That is FOUR LAYERS of fly spray folks. That ABOUT does the job. I have yet to meet ANY fly spray, applied by itself once right before a ride, especially on the trails wher mosquitos are thick, that keeps my thin skinned fainting goat diva OTTB 'Sir Braveheart' Eventer from going nutso. MosquitoHalt has been doing the job for me [maybe because everyone else is using other stuff and the bugs are getting used to that and not to the MosquitoHalt]. I use MosquitoHalt + an herbal spray - 4 coats for trail rides and lessons outdoors. 2 coats for lessons indoors where the bugs are less intense. [the herbal would never control things on it's own, BTW]. Just my experience but I neede to do the same with my calm stoic Dutch boy too.
