Few things are certain in life, but use of Dick's Dragon and Deer Deterrent is effective with all small to medium sized dragons, as well as deer!!  This picture was taken by the Chief Planter in Suzhou, China in 2007.  We stand by our motto "you don't see any dragons do you?"  The product is totally organic.

And it seems to work on Tomato Caterpillars, nary a one on 40 tomato plants last year!!
