Rat Patrol

Have just returned from a tour of duty with the Rat Patrol, an elite two-member corps of poorly-trained and squeamish rural denizens, on the look-out for vermin, of the worst sorts.
Armed with shovels, rakes, poison, a wheelbarrow, and that versatile household weapon -- a box of aluminum foil -- we have secured the perimeter, to the best of our knowledge.
However, our satisfaction with a job well done is tempered by the sinking feeling that we may have caused collateral damage, and a gang of chipmunks may now be now plotting a counterstrike.
Does anyone in the virtual world have a surefire, bottom-up, green solution to rats?
(Any jokes about politicians do not count.)
Over and out.

Global warming?

So, what do you make of this global warming concept?
The northern US has been hit with snowstorms usually associated with the Great White North.
We get our December weather in April.
What is with that?
