1. What are the most useful ID markers for bats in New Hampshire?
Focus on three features: size (compare to a human hand), ear shape (rounded or pointed), and fur color. Little brown bats have glossy brown fur and black ears, while big brown bats are larger with a more useful body and a fleshy nose. Look for the keeled calcar (a spur on the foot) on myotis species. Flight pattern is also key: bats fly with a rapid, erratic fluttering. Check out our detailedbat identification guidefor more.
2. Which bat species in New Hampshire are most often confused with each other?
The little brown bat (Myotis lucifugus) and the northern long-eared bat (Myotis septentrionalis) are frequently mistaken. The northern long-eared bat has longer ears that extend beyond the nose when laid forward. Another pair is the big brown bat (Eptesicus fuscus) and the silver-haired bat (Lasionycteris noctivagans). Silver-haired bats have a frosted look with white-tipped hair. Use a good field guide to separate these lookalikes.
3. Where in New Hampshire do people usually notice bats first?
Most first sightings happen around the White Mountains and Lake Winnipesaukee region. Bats roost in attics, barns, and under bridges. Prime viewing spots include the shores of Squam Lake and the forests of the Pemigewasset River valley. Towns like Conway and Franconia report high evening bat activity.

4. What is the best season and time window for confident bat sightings in New Hampshire?
Summer months from June through August offer the best odds. Bats become active just after sunset, with peak activity between 8:30 PM and 10:30 PM. Migratory species like the red bat appear in late August. Maternity colonies are most visible in July when mothers forage heavily. Avoid cold nights below 50°F; bats are less active.
5. How can you identify bat roosts and guano in New Hampshire?
Look for dark, greasy stains at entry points (cracks, eaves). Guano piles are small, dry, and crumble easily. Big brown bats often roost in buildings, while little brown bats prefer trees and rock crevices. The smell of ammonia is a telltale sign of an active roost. Always wear gloves and a mask when investigating.
6. What should you do if you find a bat in your house in New Hampshire?
Stay calm. Open a window or door and dim the lights. The bat will likely find its way out. If not, wear thick gloves and place a container over it, then release outside. Never handle bats with bare hands. If you suspect a bite or scratch, contact the New Hampshire Fish and Game Department.
