We buy a hot pepper spray (imagine that!) from Gardener's Supply that does a good job of keeping away chipmunks from our peppers, flowers and spices. Check out their website at www.gardeners.com. No affiliation. Just a satisfied customer. I sort of like the idea of protecting the fruit of El Grande with El Grande! No, you are not supposed to use it for anything else. Don't even go there. :^) Regards, Dot in DEE-troit
