I've had problems with doves hanging underneath my carport pooping on my car and stuff. Those fake owls don't seem to work much. I got myself a rubber Black Momba. I put that thing down on the ood of my car and the doves are history. But what do you do with a rubber black Momba once the nuisance has been abated? I'm getting a new hot water heater put in. i guess I could coil the snake up at the base of the water heater. That would shock somebody. Plumbers charge moree than doctors--better not give them an excuse to up the bill.
