We have had our property line landscaped with "deer resistant" shrubs. We sprayed Deer-B-Gone, and they are still eating. Is coyote urine a possible solution, and, if so, where can we find it to buy? Do you have any other recommendations?
Deer will sample anything that is new in the garden and will eat anything, including poisonous plants, if they are hungry enough. Nothing deters all of the deer all of the time. Garden centers sell coyote urine, and it is available online. It is a good idea to vary repellents, but nothing will really deter a really hungry deer. Some people sprinkle human hair or hang small soap bars in their trees or sprinkle around Milorganite. Some people have tried everything and have given up. Surrounding the shrubs with bird netting or fence will probably work better than repellents.
Here is a fact sheet that provides more detailed information on Using Commercial Deer Repellents to Manage Deer Browsing in the Landscape.
