We wanted expert information about bats so we contacted Bat
Conservation International's Barbara French, a Conservation Scientist
and Science Officer. She is also caretaker of bats at the Austin
Bat Hospital. (

Ms. French graciously answered all of our questions below.
We wish to thank her for this fantastic interview!

1. What is the most endangered species of bat in the United States?

Well, it would be difficult to say that, of all the endangered species, which is the most endangered, although we can say that the gray bat is beginning to increase in numbers. Instead, I would simply say that the species of bats classified as endangered by the federal government include the following:

gray bat (Myotis grisescens)
Hawaiian Hoary bat
(Lasiurus cinereus semotus)
Indiana bat (Myotis sodalis)
lesser long-nosed bat (Leptonycteris yerbabuenae)
Mexican long-nosed bat (Leptonycteris nivalis)
Ozark big-eared bat (Corynorhinus townsendii ingens)
Virginia big-eared bat (Corynorhinus townsendii virginianus)

2. Do all the bats in the United States use echolocation or are there some that do not?

All bats in the United States use echolocation.

3. What is bat guano used for?

It is a popular fertilizer for plants.

4. What should people do if they find bats living in their attic?

Bats sometimes roost in attics without problems, but they should not be allowed to enter living quarters. If bats live in the attic and the residents of the home would like the bats to move out they should use proper bat exclusion methods that utilize netting or tubes to create one way valves that allow bats to exit but not re-enter the building. After a week the tubes or netting can be removed and the openings permanently sealed shut to prevent the bats from returning. You can find detailed information on how and just as importantly, when to do bat exclusion on our website at: www.batcon.org. Just click on "bats in your home" and then "do it yourself".
