Any flavor doesn't matter at all. You can also pour it any place and they will eat it. Pour it on the ground and they will eat the dirt. I try to find rotten matterial and pour it on that. A big long really rotten log is great.what do you pour it on? Do any flavors work better than others? I poured some on a rotted fallen down tree 5 feet from a corn pile and they destroyed the corn, but did not touch the tree.
