Yep, we have been thinking about that. We have two game cameras and a GoPro. The game cameras are probably the best bet as they can record more, are motion activated and have the best storage so it would last all night.

He had 19 other baits you could use including peanut butter mixed with baking soda. He also used used fine mortar mix although he said you had to be more careful with that as it could harm other animals if they ate it. I may try the Jiffy mix with the baking soda. He said the important thing was always to use two parts soda to one part of whatever you mixed with it.
