We have used this product to put in front of trail cameras in the past and it seems to work really well.
The first time we had a camera out we had no attractant in front of the camera and after a week we had 17 pictures of deer just moving past on the trail the camera was looking over. The next week we tried Stump Likker and after week 2 we had over 75 pictures of deer licking and biting the rotton stump we poured it on.
I feel like it works well and we still use it today. Great product.
