I am interested if anyone has watched bats that are roosting on the sides of brick or concrete buildings.Also bats roosting under shutters on brick or concrete houses.
What I would like to know is how high the bats are or were on the building and if they roosted there all summer.
I am going to be experimenting using patio blocks and concrete silo staves in a bat house.
I have enticed a northern long-eared myotis to roost behind a pile of 1" x 6" stack of old redwood lumber stacked approx. 2 ft. high on the south side of of our brick house. The bat can easily take flight from this low height.
High Kent I have not witnessed bats roosting exposed on brick buildings, only when they were behind something like shutters etc. Below is one of my bat house sites in which the building is entirely brick. Bats formerly roosted in the attick on brick and wood and on the exterior behind shutters. The bat houses I mounted seen below face west and are on the rear of this entirely brick building/house . The east side of the building (no photo yet historic building no bat houses allowed on front) has shutters and a few bats still occasionally roost on brick behind the shutters on the east side although the majority now roost in the bat houses. Modifications still need to be made at this site and I have given the advice and bat house modifications to the new owners. These bat houses are occupied by Big Brown Bats which have never used the darkest house which is probably too hot for them when facing west especially in summer. The bats are using the other two bat houses. FYI the shutter height was approx 15ft. high and the bats formerly did use them for most of the summer. I think expermimenting with brick is a great idea/approach. Will be eager to hear any success you have.. Joe..
I've seen them frequently on brick behind shutters from about 4-9 ft off the ground. I'm in Louisville, KY. We actiually had one roosting on exposed brick at my office building at about 7 ft right next to the door. It finally got spooked when folks kept entering the door and swinging the door back.
