That’ll kill anything that drinks it - coons, dogs, cats, squirrels, fox, birds, deer, kids, etc.
Not saying that they will all drink it, just saying they’ll die if they do.
It works well. It is a simple solution to prevent most of these animals from partaking. The following will not: cats, squirrels, birds, deer. Since fox are close to dogs, and dogs eat dam near anything, maybe. But you can reduce the collateral damage by only using it overnight and in a closed-in area that only coons can access, such as elevated places, e.g., tree stand, crate with hole, etc., and then put it away during the day. You will not need to use it daily (er, nightly), as after a few days, the traffic and the word seems to get around.
