At least it's gone before we have guests over tomorrow. Here's hoping it is the only one we have, and it didn't leave little mouse offspring for us to discover *next* week.
If that's the case, I'll probably splurge and call Womack Pest Control again. They came here last year and the ants never came back (in force, that is. Not putting the cat food on the windowsill probably didn't hurt.) That's assuming the guy who came last time is still alive. Wow, was he old. (insert your own old guy joke here)
