Extermination of Bats

---

Tri-colored bat (formerly eastern pipistrelle) (Perimyotis subflavus)
Family:Vespertilionidae

While it is likely that more occur in the state, a single PISU specimen has only recently been reported in CO (Fitzgerald et al. 1994).  In other parts of its range it is found mostly in open woodlands and except for small colonies is not often found in buildings (Barbour and Davis 1969).
