At last - a solution to Australia's can toad problem. Decades ago the pest was introduced from Hawaii to combat bugs that were attacking sugar cane, but instead of eating the target beetles the cane toads went about settling down here and have been destroying the native habitat ever since. Cane toads have recently reached Perth in Western Australia. Now they are established in every Australian state.
Everything has been tried to kill them from hitting them with sticks, gassing them with carbon dioxide, to freezing them. None of this has had any effect on their numbers. A way has now been found, however, of killing off the pests. Placing a few teaspoons of cat food next to ponds in the Northern Territory attracts meat eating ants. When the baby can toads appear from the pond they are eaten by the ants.
Most native creatures are affected by the poisonous toxin put out by can toads. Fortunately, the ants are fully resistant. All the toad eggs hatch at the same time, so if you activate the ants you win the battle. The ants kill 98 percent of baby toads in the first two minutes. Eighty percent of survivors die of inuries during the next day.
Already do-gooders are complaining, saying ants killing toads is inumane. One species killing another is as natural as it can get. What else can be done? Are we expected to give them a packed lunch and send them on they way?
