There are two kinds of alligators.
First, the good kind that you never see and you know it is not close by.
And, the bad ones including that one outside right now that you want to know how to get rid of.
Alligators are pests when they lurk in your yard, pond, or anywhere close enough to you or your livelihood, such as when they tear up fishing nets to eat those fish you were catching to feed your family.
Or like that woman in Florida who returned home to find on in her kitchen, not a good thing.
If they are not in places that we want them to be (a back yard near the kids swings), or the alligators are not costing us money...they are great fun, ugly but great to look at and a wonderful source of revenue from tourists.
But...back to the one in your yard.
