Cinnamon in the Sandbox--- Did anyone else know this!?!?!?!? (I might be trying this in the apartment playground area.. it's not sand.. more rocks.. but heck.. would love to keep out the bugs and cats!) Now that its getting warmer, the kids are going to want to play in the sandbox. Cinnamon in the Sandbox keeps the bugs away! I knew cinnamon repelled ants... but I never thought of this! Brilliant! I've also heard it will keep the cats out.
