I hope you are joking...  ethics of poisoning campsite "pests" aside,
antifreeze is also strangely delicious to dogs and cats, forgetting
about that frisbee later or spilling a little could cause a few animals
insides to turn to jelly... please dont do that.  Please don't use
antifreeze as any kind of tool other than as intended for the engine.  I
have seen a cat who ate it, it is really, really terrible stuff.  And
seeing what the keeper of that pet goes through is also terrible.

I think the best approach is the secure your goods, dont leave dogfood
or antifreeze on the roof.  Or, invest in some very strong containers
for your roof cargo.
