You can trap them, but must release them 50 meters from where you found them. Bloody things are protected.
40 meter plane tree in my backyard has not one leaf on it. Mop top robinias are acutally stick robinias.
Tried the chemical stuff, rain washed it all away 3 times.
Got a cat from a colleage at work. Bloody thing has a female, and had 2 kittens.
I even appeared in the local paper last year trying to get our local council to do something.
I just give up.
Let those greenie commie bastards get away with murder. Save the bloody possums at any cost and end up with Melbourne's bayside suburbs looking like agent orange has hit them.
