Again from my own experience ..... Bonemeal & bloodmeal once they become wet (You buy the stuff dry & you apply it dry) - will smell like carrion, decomposing animal matter - which it actually is. I've found that it attracts coyotes + foxes + raccoons + skunks - but NOT squirrels hereabouts for me (Mid-central Ontario).
Occassionally such critters will dig down for it IF they detect a quantity of it in the soil, under the surface. I've found the best approach is to mix it well with the soil so there's NOT a pocket of it. Not a lump of it for the animals to detect & to attempt to dig up. When blended with the soil they WILL be attracted to it by it's appealing - to them - odour. But they usually realize that to eat it they're going to get quite a lot of 'fibre & grit' with it, & after a brief smell-taste will likely move on to the fella next door's garden who has put a dozen Grade 'A' large white Leghorn eggs under his Giant pumpkin seeds.
