The best deterant for most animals is the urine of a male carnivore
since i doubt you have very many male wolves in your backyard (or you wouldn't have the infestation of various felines)
So the best thing would be to get the healthiest, biggest man in your house on a red meat eating streak for a week, and spread his urine around the perimeter of your yard/whereever you need to keep them out

you'll need to repeat that every month or so, but it is effective. My grandmother always kept rabbits out of her garden that way
