I live in a city with a big rat problem. My herbs are planted in window boxes hung from the chain link fence. I came out this morning and my basil and parsley, which I put out last week, were chewed down to nubs. I can't use Ropel because eventually I want to eat these herbs, so is there any other solution? Something I could plant in the same box so the rats would stay away maybe?

Thanks for any advice.
