Whitjr,
Being a new grower, I haven't tried this yet; but I trapped up until last season, and I still have a pretty good store of coyote urine. I just add a dash of glycol, and keep it in a freezer.
I am thinking of putting some in a mist spray bottle, and spray down areas around my beds. Also, soak and hang some felt scent pads around.
I don't know whether or not this will work, but I'm gonna try it.
Prolly have to refresh after a heavy rain, but I have plenty. Plus, most all trapper's supply dealers carry it.
Whatever the results, I'll post on that around June 2012.
I'll prolly pee there too. ... LOL.
