removing a "bat house"

Asked September 16, 2018, 2:55 PM EDT

I've had a bat house (granddaughter built) in my driveway for about ten years with absolutely no sign that bats have ever been there.--no sight, no droppings. I'd like to take this out of my driveway to utilize the space. (Would also like the bat house to be utilized by someone nearer a body of water if I can find one.) My trees have grown to surround the structure so I have no hope of its helping bats (sigh). Should I wait to disassemble the bat house (on a 22 foot pole) just in case or is my conclusion pretty much on target that no bat lives there? Also, how should I proceed with this knowing that wasps, hornets or whatever might have nested inside?

We'd first suggest spending some time monitoring the box, during the day for wasp activity, and at dusk for bat activity.

If you were bat-proofing your house, now through November would be the prime time to do it. We understand your concern about the possibility of a wasp nest though.
Perhaps waiting after a good couple of frosts in October but before hibernation in November would be a good time to act.
Take a look at this page (and enclosed links) from our website: https://extension.umd.edu/hgic/bats

You could also call the Wildlife Information Hotline run by the Department of Natural Resources, which can be found in this publication: https://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/wildlife/HG90%...
