Keeping rattlesnakes out of your yard if you live in the desert and have kids/pets is very important. We found rattlesnakes in our back yard within a couple weeks of moving in. Snakes in the desert are attracted to your water features/pools/irrigation systems. They will find the smallest hole in your yard's perimeter to enter through. Make sure all rodent burrows are filled in in side your yard and outside the perimeter as well. Make sure every inch of your yard is tightly secured every month or so. A few months after installing this we found 2 rattlesnakes in one night in our yard and the next morning I found the new rodent hole in my back yard that they used to get in. The UV resistant zip ties last for 3-5 years in sunny areas, for a more permanent fix use wire.
