Bat houses and distance from main house
At my vacation home in Delaware we seem to have an over-whelming amount of mosquitoes this year. I was reading how bats can eat their weight in mosquitoes in a day and thought maybe I should erect a bat house. and maybe one here in Columbia Md would be good. However, I do not want to entice them into MY house. I just went through that and it was scary with one flying around my bedroom. I can find nothing that tells me how far away from a residence a bat house should be, or how high. Can you help? Claire

We don't have any specialists in bats here, but the Maryland Department of Natural Resources (DNR) has information about design and placement of bat houses. They should be placed at least 10' high and 20-25' from the nearest trees. Bat houses do not have to be placed on the side of a house but could instead be placed on a post away from your house. http://dnr.maryland.gov/wildlife/Pages/plants_wildlife/bats/batboxes.aspx
We recommend that you contact DNR if you have specific questions and concerns about attracting bats.
Another good resource would be Bat Conservation International.
