An ant expert has helped inspect more than 760 spots across the island to check for one of the world’s most invasive insects.

A government spokeswoman said the searches had taken place after red imported fire ants were first identified in Hamilton Parish in November.

She explained: “To date, only a small number of nests have been identified and treated, with detections limited to two locations in Hamilton Parish and Hamilton commercial docks.”

A UK Overseas Territories fire ant specialist is helping staff from the Department of Environment and Natural Resources to assess sites, detect and control the species.

The ant, Solenopsis invicta, which grow up to a quarter of an inch long and are native to South America, can cause significant environmental damage and its painful stings can persist for days.

The spokeswoman said: “Bermuda's response remains focused on early detection, rapid intervention and preventing the establishment and spread of new colonies.”

The DENR hopes to eliminate colonies and target the queen ant by placing bait at several sites across the island, which is designed to be carried back to the nest.

The spokeswoman added: “The department will continue to work closely with local and international partners to protect Bermuda's environment, infrastructure and public safety from the impacts of invasive species.”

The Royal Gazette has asked the Government about the cost of the overseas specialist and how long they will be in Bermuda.

The public should not disturb suspected mounds because the species can become aggressive when threatened. They should report any suspected sightings with photographs and co-ordinates via fireants@gov.bm.

Sam Fraser-Smith, of PlantLab Ltd, discovered the invasive insects in Hamilton Parish last year. He contacted the DENR after a family member was stung by an unusual ant while standing on a residential lawn.

“Recognising the potential significance of the discovery, Mr Fraser-Smith collected several specimens and promptly delivered them to DENR for identification,” the department said in November.

“Specialists from the Food and Environment Research Agency and Buglife (UK) subsequently confirmed the specimens as red imported fire ants.”

The confirmed ant mounds were treated immediately to wipe out the associated colonies.
