Last summer my dog got skunked twice in one week. I used a large bottle hydrogen peroxide and about 1/2 cup baking soda. Mix in a dish pan. It will foam. wash any affected areas then rince. It should reduce any odor left on the house, ground, your self. We have alot of skunks here too. You cant leave windows open in the summer because of the odor. They spray almost every night. I have only lived here 2 summers. This year if it is as bad I plan on going to the Township and see what can be done.
