When we first moved here 8 years ago we went with rock. How I wish I knew about rubber mulch back then. We took out the pine bark in our back and have replaced it with rubber mulch. Since doing that haven't seen the bugs like we used to (and yes we have pest control) Even in storms it has stayed put. We LOVE it! As soon as were are able we will be selling off our tons of rock and will replace it all with the rubber mulch. No smell and looks really nice. I think we got ours at Lowes. If you pull your own weeds pulling out of rock is horrible. Just an added note there
