You asked us a question. What makes skunks spray smell so terrible?
The skunk's smelly armory is a horrific wonder of nature. First off, the main chemical weapons are sulfur-based compounds. They are like the ones that make rotten eggs so nasty. Second, these compounds are mixed with other ultra-sticky chemicals. They make the smell a nightmare to get rid of.
And then there's the delivery system for these chemical weapons. It's a thing of beauty, if not a joy forever. Skunks have little nipple squirters. There is one on each side of their rear ends. And each can rotate independently like an anti-aircraft weapon. I'm not kidding.
Even scarier, these weapons are accurate up to 10 feet. And skunks aim for the eyes. A good blast of skunk has pretty much the same effect as tear gas. And aside from sending you staggering around clutching your eyes and screaming, it can even make you throw up.
Before you call the exterminator to get Pepe Le Pew out of your backyard, consider this. Skunks are shy, mild-mannered creatures. They'll only spray if threatened or cornered.
Also, they're veracious eaters of bugs and mice. They're actually pest exterminators themselves.
