I saw a mention of "cane toads" arent they those giant toads in australia, i think i saw something on National Geographic channel about them, and they hide in the mud and only come out once a year or something like that???
What syd said jp, bought in to wipe something out, but ended up being worse than the bug they were wiping out!
When I lived [a dreaded time too] in QLD, where the Cane Toads are prolific, the bastards were everywhere, and I mean EVERYWHERE! I found one in the toilet at friggin' SCHOOL! and unfortunately they are making their way to N.S.W.. when that happens I'm leaving the Planet.
I once counted over 150 of them in my backyard [this was in 1979]
