I would say maybe our going in there too much. My friend talked me into trying deerpain. I tried it in two different counties nothing. Its crap and doesn't work. If you think it's the cain just turn it over with a shovel. You'll be fine.
I still say it's cause your going in too much. I do it sometimes also. I put a camera out and check it tooooo much, and then I started to scare Good luck.deer off. Find some corn still on the cob throw it oout and give it 7 days in between camera checks.
