there are deer repellant pellets you can buy too from sporting goods stores and garden centers located where deer are a problem (not all stores carry them but are online too) but they don't always work...best advice i was given for getting around the critters is plant more seeds...some for you and more for them. had a problem here with a packrat until my jack russel finally caught the bastard yesterday! i HAD 7 mk x hz...now 2. but planted more to more than cover the losses and i don't think any more packrats are about. btw, packrat = a semi-mouse, semi-rat rodent about the size of a guinea pig fully grown.
