never heard of it, and apparently google hasn't either  :)

I doubt a fly repellent would have much effect on earthworms, or that there'd be much of it in the manure or urine .... what may be a concern would be the worm meds frequently fed to horses, although I haven't seen any problems with it myself

Thanks Bill

I am very careful to make sure all manure is seperated from the horses for a "minimum" of a month before the worms get it.

a real good policy is to run {{gwi:1339922}} thru {{gwi:1339923}} along with the stable bedding [straw or wood chips] and {{gwi:1339924}} - will take care of any possible problems with horse meds, but more important, insure there's not an excess of nitrogen that may cause heating in the worm bin
