I can offer you a way to eliminate the Rattlesnakes you referred
I’ve known it to work countless times. Toss Ping Pong balls all
around the landscape…snakes mistake them for eggs and swallow
them. The end result is that the plastic balls can’t be dissolved
by their digestive system. This blocks the digestive track and
causes eventual death.
I hope this simple solution is of help to you and possibly others.
