It matters to get this right, because our native southern toad is harmless and actually good for the yard — you don't want it removed. Killing natives by mistake is a real problem, and it's easy to do in the dark. So before anything gets handled, we identify the animal carefully.
The clearest difference is size. Adult cane toads get big, often four to six inches or larger, while a native southern toad usually stays under about three inches. If you're looking at a toad the size of a softball, you're almost certainly looking at a cane toad.
Reading the glands and head
The parotoid glands — the toxin sacs behind the eyes — are the other giveaway, and they're worth learning.
- Cane toad: large, swollen glands that run down over the shoulders in a triangular shape; smooth, unbroken ridges on the head
- Native southern toad: smaller, rounder glands, with pronounced crests, ridges, and knobs on top of the head
- Color isn't reliable — both range through tans and browns, so go by size and gland shape instead
Why we ID at dusk
If you're squinting at a small toad in the dark, that's exactly why we do the ID on the dusk survey rather than guessing. Toads are out and active after dark, and a technician who handles them regularly can sort invasive from native at a glance where a homeowner reasonably can't.
Young cane toads are the hardest call, because at a smaller size they can be mistaken for adult natives. When in doubt, we don't remove — we confirm first.
Common questions
Do baby cane toads look like native toads?
They can. Young cane toads are smaller and easier to confuse with adult southern toads, which is one more reason to have someone who handles them regularly confirm the ID before anything is removed.
Should I kill a toad myself if I think it's a bufo?
We'd rather you didn't. Misidentifying a native toad is easy, especially at night, and handling any toad barehanded isn't ideal because of the toxin. Let us sort the invasive from the natives.
Are native southern toads worth keeping around?
Yes. They eat insects and are a harmless part of the local ecosystem. The whole point of careful ID is to remove only the invasive cane toads and leave the beneficial natives alone.
