It's raining toads, hallelujah?

I should've known better. For months I've been bragging to anyone that would listen that after a three-year war of attrition I had finally rid my yard of cane toads.
Then during that last big thunderstorm when the house guttering was full to overflowing - a bevy of adult cane toads launched themselves from the roof's edge onto my lawn.
A nine foot aerial dash to the ground and away into the flower beds.
Dammit! Where's that lewis gun?
