I know for a fact this will work, got to your local grocery warehouse and buy a the biggest can of chile powder. sprinklle it around the area where the skunks are digging. there noses will not tolerate the smell.
To humans, it seems like a great tool: foxes eat other animals, therefore those animals will stay away from where foxes frequent, and most predators mark their territories with urine markers. So it is logical to use fox urine.
Only problem is that defensive moves are not hereditary in skunks and other prey. Thay are learned. Therefore, your skunks will be repelled by the fox urine, ONLY IF there are foxes in the area preying on skunks. If there are no foxes around, the skunk or other prey will not know what that smell is.
So fox urine is marketed to sell to human mind, not to the skunk's nose and protection of your landscape. Gotta love American marketing.
Heh, Heh, Jodi. Not picking at you, just picking at useless rumors of cures - and there're lots of useless ones.
One USDA study was done in CA, concerning the use of mountain lion dung to ward off nuisance wildlife. I forget what the target pest was, but they found that the mountain lion dung was useless, UNLESS the dung contained the remains of one of the target pests. They could actually smell (sense somehow?) their cousins were in the dungheap, so they would then avoid the area.
Nature is so simple, but the human mind is easily confused and mislead by simplicity.
