The only reason I mentioned that about the corn is because other non-targeted animals could consume it and it could lead to their long and needless suffering adn most likely death.
But, i don't think it matters whether you pile or spread the bait. the squirrels will find it. It might take a few days for them to find it regardless, but not likely.
I've made some fine sewing needles and a few fish hooks, awls, punches outta the bones.
Hope you get em and eat em up.
