[QUOTE=Jarpur;8089615]
We started feeding a feed-thru (SimpliFly) a month ago to get a head start on the flies; we normally feed it from early March until mid-October. For several years we used fly predators from various suppliers; in this area, having shipments every three weeks worked better than oncme per month. But, the feed-thru has proved superior to the predators in our situation. We are diligent about manure control and composting, but certainly notice the increase in flies when cattle are brought into our neighborhood. The next-door, horse-owning neighbor also uses the feed-thru, which helps, too.
We’ve been using this concentrate product for the past several years http://www.tractorsupply.com/en/store/permethrin-10-livestock-amp%3B-premise-spray-32-oz; it’s relatively economical and I like being able to adjust the strength. We also generally have a botanical spray on hand, a botanical cream for use on the face, and a roll-on. I don’t feel comfortable using fly baits and we have had a problem with songbirds getting caught on some of the larger sticky traps.
One thing that does work well here is old-fashioned fly tape – the little cylinders that unfurl and cost about a quarter when bought in quantity. We hang multiples from rafters between stalls, plus use one of those stinky fly traps, festooned with a fly tape, hung from a tree branch hanging over the manure cart, away from the barn, which catches lots of flies.
We also have individual, battery operated fly spray dispensers in our stalls, mounted high and away from feed and water. Previously, we had the Country Vet brand, but this year replaced them with air freshener ones that fit the Country Vet cans; the stronger strength seems to be worth the extra cost in our well-ventilated shed row barn: http://www.tractorsupply.com/en/store/country-vetreg%3B-mosquito-amp%3B-fly-spray-maximum-strength-formula-69-oz
We are fortunate to not have a problem with horse flies, normally, but one year a few moved in, so we put up an Epps fly trap (our neighbor went in on this and we placed it near the fence line between our places) which quickly collapsed the population: http://www.horselineproducts.com/eppsbitingflytra.html
However, some of the parts are not very durable and have needed repeated replacement.
At one time, I consulted with an entomologist, who recommended spraying the walls of our barn, inside and outside, as flies like to rest on the walls. This is the product she recommended, although we haven’t used it in years: http://www.valleyvet.com/ct_detail.html?pgguid=30e079d0-7b6a-11d5-a192-00b0d0204ae5&sfb=1&itemguid=3269e3e1-7b6a-11d5-a192-00b0d0204ae5&utm_content=21985&ccd=IBSM0001&utm_source=BingAds&utm_medium=shopping&mr:referralID=9a377077-db3d-11e4-82f7-001b2166c2c0
I tried feeding apple cider vinegar, but it didn’t seem to make any difference. We rarely have to use a fly spray on our horses, but sometimes have to change the fly tape frequently. Visitors have commented on how relatively few flies we have, so I guess our program works as well as can be expected. Good luck - I hope you find something to give the horses some relief.[/QUOTE]
This is so helpful! Thank you.
