I've been reading a lot about the vanilla scented christmas tree car fresheners being used to repel flys from coops. Awhile back I asked if anyone ever let their chickens bathe in chicnchilla dust and if it was safe. I was told yes and have let my chickens take a weekly dust bath in a litterbox of chinchilla dust. They come out smelling good and all sparkly! Well while browsing the pet store the other day I came accross some Vanilla Scented Chinchilla dust! I thought "hmmm I wonder.... just maybe...." so I bought some. My chinchilla hates the stuff but the chickens seem to LOVE it! And guess what? Since they've taken their dust bath there has been a dramatic decrease in not only flies but MOSQUITOES as well! It seems all the flying/biting insects have taken a vacation from bothering my flock and they in turn seem a lot happier! And they smell WONDERFUL and are so shiny and sparkly! I see no downside to this whatsoever! And the stuff was cheap, only like $5 for a whole bottle! I wonder if this will help keep lice/mites away.... Now if only I could find something so wonderful for the ants..... Anyway, I just thought I would share this with everyone! Maybe it will work for you all too!
