I found a few threads regarding bats but none to help me with my issue. Twice this summer, my wife poked me in the ribs in bed and yelled out that we had a bat in the bedroom. Nothing like that to contribute to a sleepless night. I have some bats in our attic and can't for the life of me figure out how they are getting into the living quarters. I don't want to harm them but am checking on ways to get them out of the attic. Our house has a brick lower level and rough sawn cedar gable ends which will be painted in a few weeks. I am going to have the painter caulk everything to eliminate any possible entry points but want to get the bats out before caulking. I have found some ultra sonic or other devices that are allegedly supposed to get rid of unwanted pests in the attic. I am wondering if anyone has tried these things and if they work or not. Pros and cons would be helpful. Thanks for your help.
