Seminole Bat

Lasiurus seminolus

Low Risk

Biology

Lasiurus seminolus is a small to medium tree bat of the southeastern United States, closely related to the eastern red bat. It has rich mahogany-chestnut fur with white-tipped hairs, a 28–33 cm wingspan, and 1–4 pups born in summer.

Behaviour

Seminole bats are nocturnal, solitary foliage-roosting bats that hunt insects over wetlands, forests, and suburban areas. They often roost in Spanish moss, pine needles, and broadleaf tree foliage. They are not colonial attic dwellers.

Habits

Human contact is usually limited to a single bat found in landscaping or an open garage. Like other tree bats, they may be attracted to insects around lights. They do not cause accumulations of guano in structures.

Control methods

1Allow accidental visitors to exit at dusk on their own
2Minimize bright white outdoor lighting
3Trim trees back from rooflines and vents
4Cap chimneys and seal soffit gaps
5Avoid handling; use thick gloves or call a rehabilitator
6Document the encounter if repeated sightings occur
