Apparently the cooler nights are bringing out the wildlife in ways I would rather avoid. This morning while doing chores, I kept encountering black widow spiders. The easy moral to this story would be to stop turning over the larger, scoop-bottomed items in the yard, but I kinda need that wheelbarrow, ya see, and it's only polite to dump and change the water in the big black trough.
For those who don't know, black widow spiders prefer to make their webs in the hollowed-out undersides of well-protected areas. The simplest example for almost everyone to visualize is a flipped-over kitty litter box. One corner or one half of that shallow plastic tub (now upside down) is perfect black widow habitat.
