I grew up with bats in a house that had been part of a dairy farm (a big colony lived up in the attic) they colony had been there probably for close to 100 years - occasionally one would get downstairs into the lower house..no big deal - my father was a science teacher and had great respect for them so he was careful to catch them gently and let them go...they love barns and with the loss of barns in Vermont many have lost their homes- I am SO glad Shelburne Farms is helping them...bats RULE!!!
