Well, speaking from America, I'd say that you have a REAL PROBLEM. My daughter also has "bats in her belfrey" ... so to speak! And it's not an easy situation. The two obvious answers are: kill them, or learn to live with them. Niether answer is simple. Perhaps building another "Bat House" will work, I don't know. Over here in this land, We, THE PEOPLE, are getting sick and tired of semi legimate pholks getting rules set into law that tell us what we cannot do with our own proerty. And having said that, realize that I am NOT a bat hater. But of all the houseguests you can attract, these guests are not easy. GOOD LUCK. Bob
