Right outside my living room door, I have a huge automatic awning the width of my house that extends and can cover my entire patio. It's normally retracted especially at night. For some reason a family of bats have decided to hang from it at night after all the lights are out. I always close the storm shades at night because I don't want the morning sun to shine on the furniture. I normally flip on the patio light when I close it and once, a couple months ago, something started whipping around at high speed. The first time I thought it was a bird, and didn't think anything of it. It's been the same until one night I showed my wife and then we could clearly see that they were bats. The other night, they decided to have a party, there must have been at least 6 or 7. When I turned on the light, it was show of them circling and doing touch and gos to where they were hanging. When I went out in the morning, the area was full little black shits like mice turds. I had to hose down the house and everything around to get rid of them. Last night I sprayed quite a bit of Raid so the smell would irritate them and left on one of the interior lights because it seems they like it totally dark. I didn't see any when I went to bed, but I now need to find something that will chase them off.
