For the fourth time in the last 6 years, we found a Massasagua Rattlesnake in our building. We are located near the Des Plaines River, and have swamp on two sides of our yard and a small woodlot on another side. This one, like the first 2, was just a baby, no more than 8" in length. Number 3, which we found in spring of 2006, was a nice 2.5 footer. The cooler nights we have been experiencing seem to trigger this behavior as they look for a warm spot to hole up.
6 years ago I never new rattlesnakes were even in northern Illinois.
