Bunnies are a clear indication there are no snakes around. We see this as a sign when we camp down south, lots of bunnies a good thing, lack of bunnies means snakes. They're are rattlesnakes all over where were at. I know of no known snake deterrent though.Not really, our backyard is snake free, If we ever see them it is in the front yard. It still scares me though! We have a 6 ft wall around our backyard, then we have the "back back" yard where my bullies don't go. That is where there is a possibility, we have loads of bunnies back there tho so I am thinking not too many snakes. Now the "back back yard" hardly has any bunnies and is empty... So that worries me!
I hate snakes and am always on the look out for the rattlers (the babies too). Ace & Orion ran into a rattler a few years back!! I had one dog on one side and the other on the other side with a coiled up rattler in the middle and I was at least 15/20' away. We were on the bluffs on a walk at the end of our campsite when it happened. Thank gawd my dogs listened to me when I called them to "COME" or they'd have gotten bite. The next year a husky mix got bite in the site next to us. Luckily I carry all the #s/addresses to the local vets there for that very reason so we got them to where they needed to go. The dog survived but $2500 later. The ranger came and that snake was still in the site 1/2 hour later. He relocated it and wouldn't let us kill it. Dang it! I saw a red snake take down a rattler at the shoreline a few years ago too, that was awesome...snake fight.@JeannieCO Most good snake repellants start with .4 and end in Cal.
