Interloper update: we caught two in January. Another was trapped in March, indicative of a new hole (now fixed). Since then, there’s been no new activity in the crawlspace. In July, a fourth one made an ill-timed visit to the bait trap, only to have the next door neighbors’ cat go medieval on it. The cat received extra salmon that day.
I’ve avoided the cleanup for nearly nine months. However, this weekend I am renting a dumpster, donning my Junior Hazmat Deputy outfit and removing the dookified insulation.
