I would think if bee stings are especially an issue - stay away from the Hiney Stinger packs. Never know - could be they are trying to get back some of their product.
All kidding aside,
I think the Cliff Shot Blocks are the least messy, and therefore, would provide the least amount of insect attracting residue. I personally find the texture disgusting, but if was between that and potential death from bee sting, I will take the Cliff Shots Blocks.
