Fly spray

Fly traps! They are large plastic jars and you put a little water and fly bait in the bottom of them. It is amazing how fast they fill up with flies - thousands of them. Kind of disgusting to empty them out and recharge them - but man they eliminate a ton of flies. We were getting ours at Fleet Farm here in WI, I would think any farm supply place would have them or maybe you can order them from some place like Jeffers.
 
We use cylence on the deer.



Then we use the plastic bottles from TSC 6.95 ea. We use a liquid bait that takes 2-3 days to activate before use. Pour about an inch of liquid in each bottle and in a day you have 2-3 inchs of flies in the bottle. This stuff is great.



If interested shoot me a message and I will get you the info.
 
I had flys and mosquitos BAD and sprayed the grass and trees in the pens with permethrin 10%(Animal friendly) and haven't seen a bug in them for several days now. It's pretty resonably priced if you shop around. I also sprayed all the grass and soaked the trees around the outside with tempo(not to be sprayed in pens), it lasts for along time(couple weeks or so unless it rains) and the flys usaully hang out in the shade of the trees during the day. The deer are loving it! Make sure the permethrin is 10% and not the 1% that is sold in most stores, 1% is an actual drench dilluted to put right on the animal but by the time you dilute with water for a spray mix it's too diluted. You may have to order it off the internet. It's the same stuff the guys who have the timer foggers use. If you spray down the grass in the area they like to bed in it works great, gets right on them. I wish I would have done it a month ago. Good luck

Fly Predators use no chemicals at all, I will have information at Wills auction and also on the web page for your review. There are many ways to irradicate flies, just find which one works best for you but if pesticides are a concern, then this is the way to go.
 
Henry you are always looking out for the fellow deer farmer... I really like the idea of no chemicals in my pens to get rid of the disease carrying flies. This is even cheaper than garlic mixed in the feed.
 
Thanks Dale, I try to do my best in everything I do and even more in this business. I love Whitetail deer and certainly would do deer farming for a living if I could. Thanks again for your kind words.
 
I have used permethrin in my A1 mist sprayer. It takes quite a bit to fog enough to get rid of the deer flies. I believe the other post about spraying in the grass where the deer bed would be the best because that would get some on them. I had a shade shed I sprayed down real heavy with it and that worked well. The deer would lay in there and the flies would not come in.



Another option is to spray with malathion with corn syrup mixed in. I used about 2.5 gal of malathion and 2 gallons of corn syrup and that killed good with a bit of residual if it doesn't get rained out right away. I guess you can use molasses also but it has to be clear with out the additives. If the molasses has the mineral additives it will curdle when mixed with the malathion. I sprayed a little better than 10 acres with that mix. I had a nice peaceful yard and pens for a few days until it rained with a big wind.



Good Luck
