best rodent control around
Gonna have to disagree with this and I'll tell you why. There's no denying that the ones above are "good snakes" and that snakes will scarf down a rodent with a quickness. But just how often do they do that? On average, about once a week. MAYBE twice under certain conditions. Unless your place (barn or building is assumed) is crawling with snakes, they're probably not even keeping pace with the rodent birth rate.
According to wiki:
The [mice] gestation period is about 19–21 days, and they give birth to a litter of 3–14 young (average six to eight). One female can have 5 to 10 litters per year, so the mouse population can increase very quickly. Breeding occurs throughout the year.
In fact, the five snakes above are taking out, on average, five mice a week. At the edge of town, that might be awesome. In the panhandle, that sucks.
On my place in the panhandle, I know the snakes on my place aren't keeping up. My 60x40 metal barn is crawling with both snakes and rodents. The snakes have had 7 years to get things under control (I've only killed four rattlers in my barn during that time) and they've failed miserably. Yeah, they'll eat a few, but they're not earning their keep.
Now it's my turn.
ETA: Of course, this also means that the snakes better stay the heck out of my barn too.
