I recommend you spray wolf or wildcat urine around the perimeter of your property.  It will keep away the coyotes and they will find another place to be.  It works very well.  You may have to spray again after a rain.

Not doubting you at all, Peter. I went to look at Amazon and there are some HILARIOUS reviews

This review is from: Wolf Urine Lure-32 oz (Kitchen)

It's always humbling when you find out that your iPod was manufactured with slave labor overseas, isn't it? Well, guess what? None of the wolves who contributed to the urine samples used by Deerbusters have been compensated for our valuable liquid gold.

I know, because I'm a wolf and these jerks scammed me too. I woke up one day in my bed (I'm a city wolf) to find that Deerbusters had broken into my apartment, placed my paw in warm water, and walked away with a bladder full of my premium-quality urine. I know it was Deerbusters because they had the audacity to leave a calling card, if you can believe it (the cops must be in on it because they won't do anything)! Not only did Deerbusters steal my pee, fixing the broken door lock put me out about fifty dollars. I was floored (although most of the time, I must admit I do prefer walking on all four legs).

If my testimony isn't enough to convince you that purchasing from Deerbusters is a direct contribution to organized crime, the product they are selling is not wolf urine for "scaring deer away". I don't even think that works. I only know one deer personally, and the one time I peed on him he appeared to enjoy it (this became very awkward but that's another story entirely). This urine is mislabeled so they can secretly market it as an illegal performance-enhancing drug. Just ask anyone in professional sports, and they'll tell you: wolf urine is the go-to drug of today's top athletes.

Please grow an ethical spine before supporting these scoundrels. Thanks, and arf.

Yes, that one is pretty wild.  LOL
