One of the world’s most invasive insects has been discovered in Bermuda for the second time in two months.

A spokesman said the Department of Environment and Natural Resources identified a colony of red imported fire ants late last month.

The ant, Solenopsis invicta, is known to cause significant environmental damage and produce painful stings that persist for days.

Three mounds of imported fire ants were found and eliminated in Hamilton Parish in November.

Noel Tawatao, fire ant specialist from British-based Feta Sciences Ltd, later said Bermuda acted “in a timely manner” to tackle the ant’s presence on the island.

However, the spokesman said that the mounds in Hamilton Parish likely spread from the colony discovered at the docks.

He explained: “The discovery suggests the ants arrived through imported bulk cargo.

“As a measure of precaution, DENR is asking anyone who imported bulk cargo within the past six to 12 months, particularly from the southeastern United States, to inspect their properties.”

He added that 62 locations across Bermuda have been surveyed for the insects to date and inspections are ongoing.

Jaché Adams, the Minister of Public Works and Environment, said: “Early detection is critical, and so I strongly urge the public to report any possible sightings as it would give us the best chance to prevent the spreading of these ants.”

Members of the public should not disturb suspected fire ant colonies — but e-mail reports and photographs of sightings, along with co-ordinates, to fireants@gov.bm.
