I have a kid with a peanut allergy and when peanuts started showing up all over the place outside, we asked our neighbors the same thing: please stop giving the squirrels peanuts. We couldn't let the kids go outside in their own backyard.
Thankfully, our neighbors are all generally really nice people and not child-murdering monsters, and actually stopped it.
People: Keep your peanuts to yourself and do not feed wildlife. Both of those things are common sense.
I wish it were that easy for us. We've got a walnut tree somewhere in the neighborhood, and those furry little fucks keep bringing them into our yard and either trying to break them open on the driveway or they're burying them in the garden planters.....
