The yellow ant eradication program is up and running and the results are impressive.
Australia is almost half way through a 10 year plan to eliminate these destructive insects.

The ants can form super colonies containing thousands of queens.
It is estimated that up to 20 million worker ants can inhibit a single hectare of land.
On Christmas Island, an Australian territory in the Indian ocean, scientists say ants have been responsible for the deaths of up to 20 million red crabs.

The ants are part of a long list of invasive species, including cane toads, feral cats, pigs and camels, but have caused untold ecological carnage across Australia.
