I'm not sure it helps prevent the bugs from biting (it might), but may help them cope from it being a bit of a sedative.
The colonial partisans who fought the British during our revolution and operated out the swamps of SC use to mix vinegar with their water to help cope with all the blood suckers (there's a large variety here). Not sure if they gave any to their horses though
