Lots of rattlesnakes here in southern Colorado, and I have taken care of several over the years. When I retired in 2015 we moved into a new home right on the edge of the city limits, other side of the fence is miles and miles of high prairie with an abundance of critters. Since then I have had 2 or 3 on my patio every year and I have gotten very good at taking care of business with a garden shovel.
First time I found one I was sitting on the patio reading a book and enjoying an adult beverage. Some movement caught my eye about 3 feet from my left foot; juvenile prairie rattler with just a button on his tail. I was flailing away with the shovel, banging into the gravel, making a little racket. Wife opened the back door and asked what I was doing. I told her to go back in the house. She insisted on knowing what I was doing, so I told her I was killing a rattlesnake. Back door banged shut, deadbolt lock clicked into place!
Took a while to convince my wife that the patio is perfectly safe, so long as we take a quick look around before stepping out the door.
Good idea to give the surrounding area a good look after dispatching one rattler. About half the time I will find another one nearby.
After that first snake I mentioned it to our maintenance contractor, told him I had killed it with a shovel. He told me he uses a weed-eater or a lawn mower.
