We have sevveral flower beds for their dining convenience. We have various deterrents in place.
0. Plant distasteful flowers. Very effective.
1. Cheesy little fences a foot high that they can hop around. Surprisingly, these do some good.
2. Chicken wire fences a foot high all the way around. These work ok but are useless vs chipmunks.
3. Half inch hardware screen cages with a top. These work great but are the most cost and work to build and store.
4. An electric fence with the wires at 4" and 8" high. I did not ground this fence but put the voltage across the two wires. A grounded system is only as effective as the little beastie's connection to the ground. Works well on a heavy quadruped but not so much on a furry lightweight in dry weather. This seems to be 100% against rabbits and pretty much useless against chipmunks. Wonder where I can rent a snake....
