I am not sure that whacking a toad with a golf club is the best method to control the population of invasive species, but it is effective. The natural range of the cane toad stretches from Mexico south to northwestern South America. The toad was introduced to various Caribbean islands in the early 20th century to wipe out the cane beetle. Like everywhere else, the effort was unsuccessful. Many native frog and toad species are now threatened because of the cane toad. It is also important to know that Mexico, Central America, northwestern South America as well as the Caribbean has the highest number of threatened amphibians in the world. I have read that the cane toad is only a nuisance outside its natural range.
