In efforts of high-tech pest control, Australia is deploying drones and DNA technology to battle the yellow ants causing massive destruction.
Yellow crazy ants, known for their aggressive nature and acidic venom, are wreaking havoc on Australia’s wildlife. As reported by The Wet Tropics Management Authority, these ants are not only attacking frogs, lizards, and nestling birds but are also disrupting the delicate balance of the Wet Tropics rainforest—one of the oldest and most diverse rainforests on the planet.
To counteract this crisis, Australia has turned to innovative technology. Researchers at James Cook University, led by Peter Yeeles, are using Environmental DNA (eDNA) analysis to detect these elusive pests. By collecting and analyzing DNA samples from environmental sources like rainwater runoff, scientists can pinpoint infestations with remarkable accuracy.
Once identified, drones and helicopters are deployed to target and eradicate the ants. This precise approach, as explained by team leader Gareth Humphrey, allows for efficient treatment of specific areas without the need for widespread baiting, making the eradication efforts more effective.
Since their arrival on Christmas Island over 80 years ago, yellow crazy ants have become a significant financial and ecological burden. Managing these pests costs Australia more than $6 million annually, with local governments contributing around $180,000 each year. Their impact extends beyond environmental harm, affecting agriculture, infrastructure, and tourism.
One resident shared her frustration as the ants invaded her home, damaging electrical wiring and harming pets with their corrosive formic acid. The ants also threaten sugar production and tourism, exacerbating the challenge.
In response to the ongoing threat, Australia is investing $24.8 million to combat the yellow crazy ants across Queensland. Despite the considerable expense, technology is providing a much-needed edge in this battle.
“We’re gradually getting on top of the yellow crazy ants,” a spokesperson commented.
