It is a gel type substance that you pour over stumps, logs, or mix with feed. I absolutely love it, and the deer devour it. here are a couple pics.
This is right after I put out the cam and poured it on there. If you look at the stump you will see corn and a normal looking stump with no damage
Look at the stump only 30 minutes later
I That was last year the stump has gone from flat on the top to now it has a 4"-5" depression and also the root legs are all eaten up. I use this stuff all the time and swear by it. I have used the persimon and apple and the apple is by far the best.
BTW you can get it at bass pro. It is made in Louisiana by the same people that make deer cane
*EDIT* use this link and look at the picture associated with the number. Apparently I have become computer illiterate. I've been having trouble posting pics on here from photobucket the last couple times now. WHAT'S THE DEAL??!!!
