About 3 weeks ago, we started seeing the occasional crawfish on the driveway. Then one appeared just outside the door from the garage into the laundry room. They were always dead, so we just ignored them after sweeping them away.
The hubby and I laughed it off, but then, this morning, there were at least 5 of them working their way across our yard and into the street. The youngest (or at least runtiest) of them had been squished (likely by an early morning bike or stroller) as it attempted to cross the sidewalk.
I think that brings us up to a dozen or so in the past month. What the minimum number of unlikely critters to constitute a plague?
