Since then I've always provided a dark shelter with a heavy tarp over the door that touches the ground.
I have relatives in Ontario and they warned us about the blackfly and deer/horseflies before the season arrived - I thought they were making a big fuss about nothing till they hit us, I guess they prevale more down the east coast into New England - don't know how bad they are in other parts. They never seem to be around on dull days and we've found that if we ride later on in the day they aren't about so much either and never come into the barn so I've been bringing them in at about 11am and then they go back out later on - but costs us almost as much in hay as it does in the winter, now that we seem to have mostly 'normal' flies they are settling back down again. If it gets really hot I bring them in anyway as they seem to prefer to stand in with the fans on.
No wonder all the primitive horses left this continent!!!!
