A couple days ago my son noticed a 3 foot long snake in the greenhouse. The day before I also noticed a smaller 8 inch snake in the greenhouse basking in the sun. Snakes are wonderful for rodent control. Even though they come in the greenhouse when the weather gets cold outside, when working in the greenhouse, one does not see them all that often. It won't take long to rid the mice, any mouse running around inside the greenhouse will soon become dinner. - Millet (1,166-)
