I recently had to cut down a large Ficus for various reasons ,that literally had thousands of dead leaves stuck in it. I had Racoons hanging out and wanted them gone. I thought the dead leaves would be great in my girls play yard so I scattered 6 trash cans full. Now I'm bitten up every time I'm out there. Could that be the reason and what can I use that will not harm them? I've put diatromaceous earth all over but am bit up every day. I live near the ocean in Huntington Beach , California.
