This is possibly the best and most humane way of killing a raccoon. You can first trap them as mentioned before. Once you have them caged, you can take them with you to a vet or a professional animal trapper to have them euthanized. This typically involves carbon dioxide chambers or even a serum injection which provides a painless death to the animal.

With that, you have some ways in which you can kill a raccoon humanely. There are plenty of nonlethal approaches to take when you want to get rid of a raccoon, and it’s recommended you attempt those first. If that doesn’t work, you can attempt some humane methods of getting rid of them. But no matter what happens, avoid drowning or poisoning raccoons as both are incredibly inhumane, and poisoning can help spread disease and puts any pets you have at risk.
