Many towns in Queensland have problems with flyingfoxes......
Specially if your house borders a nature reserve, with thousands of the hairy little creatures , hanging upside down urinating on themselves, squarking 24 hours a day, and the worst is the almost rain like shitting on everything......
And it takes the paint off cars.
Thay are a protected species, so you can't throw firecrackers at them, although firecrackers are illegal in most states.....
good luck
