I've had bats for quite a few years now. They hang on the gable vent on the side of my house, and eliminate a mosquito problem at our pool. Fearing the amount of guano that had gathered on the screen leading to the attic, I called and spoke with William of the Wildlife Division. He came out and cleaned the mess the bats had made, fitted a grated screen inside the vent so the bats cannot attached inside the vent, and spread the guano he gathered around the base of the tree where I have placed a bat house. I was amazed when he even showed me a video of the procedure as he completed the process! I am so please with how well William took care of my bats, and the process to ensure they land elsewhere. I am so grateful!
