Fly FactsBy Kentucky Equine Research Staff · April 7, 2011
Flies prefer dark-coated horses to those with light-colored coats, but how much more attractive are the blacks and bays? Research in Hungary involved coating black, brown, and white horses with a sticky substance, turning the horses out in a pasture, and counting the flies stuck to each horse every other day for eight weeks. The totals showed that compared to the white horse the black horses attracted 25 times as many flies and the brown horses attracted 15 times as many flies. The study also turned up the fact that flies are attracted to red cars.
