Just looked at your article and I am in a fit trying to deal with the porcupines. Last year they damaged 13 trees killing 2 and they are back. I live in Wyoming and the trees are at our cow camp that usually becomes inaccessible during the winter. I may be able to make it there one more time if we don’t get snow and wind. We have used fencing and that is like a ladder and I used some spray called Repelex and it didn’t work last year. I am thinking the liquid bird repellent may be an option. I have been advised to put tin flashing around the trees but what happens when the snow covers the tin? In this country it takes forever to grow a tree so we try very hard to protect them. The damage has been mainly to crap apple trees and blue spruce.
Would you please let me know if you think this sticky stuff may work? I would appreciate any help you can give me.
When porcupines find a good food source during the winter, they can be tough to stop. It sounds as though this has been the case at your cow camp. There is no doubt the 4THEBIRDS LIQUID REPELLENT would stop them. Treat the trunk of the tree above the snow line and you should be able to stop them. Remember, if the snow gets above the treatment, they’ll have access. Treat above where you think it will accumulate (at least 3-5 feet up above the snow line) to insure you have enough protection. This should be enough of a barrier over which foraging porcupines won’t go.
