Can using an introduced animal to control another animal actually work on a large scale?

I have seen on the Internet the devastation being caused by cane toads and I was wondering if this is just a one off occurrence. If so, should this technique be used more often? Surely this biological control will actually work well if the research on the chosen animal is done properly. Also if it goes wrong surely the animals can be removed quickly so why didn't they do that for the came toad? Obviously it would be better if the animal didn't have to be introduced but it would be much more friendly way of controlling animals. No killing would be involved so it would also suit animal activists and if it works then one could focus less on controlling the actual pests population meaning it would also be cheaper.

They have not effected the natural environment very badly even though no research was done on to the effects. Surely this shows that if we are carefully then it is possible.

    May 31 2013: I think it's just sweeping the mess under the rug, replacing one thing for another seems like bad math to me if you're trying to subtract and get zero, it's best not to add anything extra unless it's going to equal zero.

    Animals are variable driven beings, they need many variables to thrive, cause many variables to happen where they live and determine the variables of other beings that live in the same area.

    With those facts I'd think, using animals to rid other animals is a bad choice.
