Folks, there was a happy (for me) ending. After a sleepless night, I carefully exited my apartment this morning and started walking to work. And there, at the bottom of the porch stairs, was a dead tarantula. Guess that bug spray worked after all! And today was the regularly-scheduled pest control treatment at my place. When I got home from work, the tarantula carcass was gone. I don't know how or why, but I don't care.
