Introduced in 1935 to eat cane beetles, cane toads failed because their behavior and diet didn’t match the target pest (the beetles live high on cane stalks where toads couldn’t reach them). Instead the toads bred and spread rapidly across large areas, ate native invertebrates and small animals, and their powerful toxins killed or debilitated native predators and scavengers, causing cascading ecological damage—so they became a widespread invasive pest rather than an effective biocontrol.
