Why aren’t the cane toads eating them?
Thats actually a good question.
From what I gather from Google:
The cane toads were introduced to australia to protect the sugarcane crops from pests. Specifically insect borers. The trouble is that the giant south american frogs couldnt attack the particular bug that attacked the Australian sugarcane becase the bug attacks the tops of the plants, and the frogs are bad climbers. So the frogs became a nuisance themselves without even being able to do their job. Lol!
But cane toads DO eat mice- and have been introduced to tropical island for that reason.
So yeah. Good question.
The current mouse plague seems to be two plagues centered in two far apart states: New South Wales, and Queensland. With NSW being the worst.
Queensland is in the north - in the tropics/subtropics (like Florida), and NSW is like Ohio. In the temperate zone cornbelt or wheatbelt.
The cane toads only thrive in the tropics and subtropics. Their whole range in Australia pretty much coincides with boundries of Queensland at the top of Australia. But New South Wales is way down south in the temperate zone. So it doesnt have cane toads to help kill the mice. So thats explains it for NSW.
But why the toads arent doing their job in the north I dont know. Maybe they ARE eating mice, and the plague would be even worse there if the toads werent there!
