I would kind of disagree with this, well, not that it works but that it is a good thing to do. That fly spy can be very irritating to the skin. Keeping it on the hair, without working it down to actual skin contact, will help keep flies away while minimizing skin absorbtion. Some of the chemicals are NOT good for any living thing. If I get the stuff on my hands, it kind of burns. I am very careful to spray my horse near his sheath (where the midges make him miserable) where there is plenty of hair and avoid the sheath itself , where the skin is thin and sensitive.
