There are sprays to discourage moose from chowing down on your foliage- in my case two new pear trees. I was looking at Plantskydd which is supposed to deter moose and deer and things by being made of porcine and bovine blood mixed with vegetable oil and suchlike. We did get a bear in our neighborhood last year for the first time ever. Is it possible that spraying something like this would attract bears? What would I want to keep in mind? Not that I expect any more bears unless we have another pandemic but just in case.
