So Cuz tried it, then they both told me. Rye and Cuz, now, both swear that filling a few baggies with water and hanging them high above the pen keeps the flies down because they (the flies) think that the baggies are hornet nests. I don’t know if it will work or not, but I’ll give it a try.

I use the expensive flea drops from the Vet on the “girls” and spray the pen, houses and underneath with High Yield pesticide. I, also, pick up the feces every day, putting them in a sealed container and have fly strips hanging around the pen.

By the way, I plan to run the “girls” in the morning

the Ladies a bath. Shame no one is here to take pictures.
I'll just bill Brag for his share of the bath
