RE: Deer Co-Cain ???
I used the regular liquid bottle last year and had great results. I placed it close to a break in the trees not terribly far from my feeder. There was no path there to begin with, but within 3 weeks of placing it there, I had major traffic starting from that point heading towards my feeder.
I bought some this year (the powder), but just put it out last weekend . . . haven't had a chance to go back and see if its had any traffic.
