Doin' it right with Dairy Cows

Ok got a question for anyone out there that may be able to help out. My dairy cow is in paddock shift system by herself with her baby. So there isnt a ton of poop in her pasture... its nice an clean ... not swampy areas. But yet i seem to have a terrible fly problem with her. Especially on the underside of her udders between the teats. They bite her like crazy an i have tried D.E. an tried using geranium oil an teatree oil on her... an nothing seems to help. So i am now turning to everyone out there at permies for possible solutions?!?

wish i could help, Kristie.

we had a rough year last year with flies, so we ordered some fly predators this year (http://www.arbico-organics.com/product/fly-control-program-alt/beneficial-insects-organisms) they seem to be helping, although i realize that isnt much help to you now...

we tried a few natural/organic fly sprays last year and none of them seemed to do much good.
we also DE her, but it doesnt work for long either...

hopefully others can help.

Hey Kristy,
Sorry to hear about your fly problem. A few years ago a large commercial poultry operation move onto the property behind us. We suddenly were swarming with flies every where. What we did was set up stink barrels. You take an old barrel ,cut a small hole in the side large enough to put a small pvc pipe in. Glue a t on each end of the pipe. Next drill several holes in the lid and cover the top of barrel with fine mesh screen and put lid back on. Fill barrel about 1/3 way up with water. just enough to keep it from blowing over in a wind. I put vegetable oil on the water and place a large piece of rotten meat inside floating in the oil and water. The flies are attracted to the rotten meat get in through the t-piece , They try to fly out the top and get trapped by the screen. It works great. Word of warning though. Place barrels downwind of you and wear a mask when you clean them out once a month. They do stink but are very effective.

@ Kristie -

Ultra Boss seems to be one of the few pour ons that are ok to use on lactating cows:

here are the ingredients, if anyone has any feed back on them, im all ears.

INERT INGREDIENTS*** 90.00%

TOTAL 100.00%

i also 2nd Becky's suggestion.
i have used raw meat in standard fly traps instead of the stinky yellow stuff that comes with it, and it works pretty good.

thanks kelly, but im really looking for a natural, or better yet organic way of controling the fly problem. An Its not the large black flies, these are little annoying biting flies. NOt only are they biting the crap out of my milk cows bag, but also around her eyes some. An around my highlanders eyes. So i really need to find something that work. like ive said though i have tried d.e. an ive tried geranium an tea tree oil. An they arent helping.

I just wanted to let you all know that i have started a new thread that hopefully will help a lot of people out. Especially with it being fly season! https://permies.com/t/36829/cattle/biting-flies-beef-dairy-cows#287259
