Where do we sign up?

The cane toad invaded Australia long ago. Since then, the country has been at war with the large amphibian not because it is an animal, but because it destroys crops. These toxic toads also kill off wildlife that try to eat them.

The newest weapon in the battle appears to be a cat food can. Researchers found that leaving an open can of cat food near a pond where baby cane toads dwell attracts a meat-eating type of ant. The ants also happen to be immune to the toads’ toxins, and they can successfully eat the baby toads.

If we can use the animals against each other, we might just win this thing.

Key quote: “In one spot we tested, 98 percent of the baby toads were attacked within the first two minutes,” researcher Rick Shine told Reuters. “It was a bit like a massacre.”
