At one time these monster toads(one toad was in flower garden(5lbs.) were  
prop-
agating so fast that we had to take dire measures for our  small children as 
well as
all the pets. When I spied one I would have water spray bottle on hand and  
some
Morton salt. I'd spray the toad then drop a handfull of salt on them.   The 
next time 
I saw them they were like petrified(dried up).
