What's That Bug? does not endorse extermination

I live in the Northeast and I having a problem with these black bugs in my basement. I always thought they were called potato bugs but when I looked for a picture of potato bugs on the net, I realized that the bugs in my basement are something else. I would like to know what they are called. The are black. They have a shell-like back. They roll into a perfect ball when they are touched. They don’t bite. I use to play with them as a child. I have not seen them in the winter months. However, somehow, they find there way in my home when the weather breaks. Do you know if they have a name?

Dear Connie,
It sounds like you are describing Sow Bugs or Pill Bugs. These are not insects but Isopods, a group of Crustaceans. They are often numerous in damp places including basements and gardens. They are called Pill Bugs because of their habit of rolling into a ball. The Common Pill Bug, Armadillidium vulgare, is dark in color, often approaching black. They are omniverous, and feed on young and decaying plant material. Unless very numerous, they do not make significant damage. They have few predators because of a distasteful secretion, but a spider, the Sow Bug Killer, is a natural enemy. Here is a photo we just took in our garden.
