Hate to rain on your parade guys, but critters are evil. For some years ,at my house, I have been at war with them. Especially raccoons, opossums, and feral cats. They burrow under the siding on the house and wreck havoc. I have rewired my phone lines 5 times. They tear through insulation. I am pretty sure there is a dead opossum in my wall now... there's a smell for you. I have hired exterminators, set traps, and got a few with a pellet gun. Still they come. BTW opossums are the most disgusting creatures on Earth. They will not touch the bait in a trap until it is spoiled and has some mold on it.
Currently I am constructing what has been dubbed "The Great Wall of Trump". It is a concrete barrier that will surround every inch of the house. My first choice was to dig a moat and fill it full of sharks with lasers attached to their heads.
