Antivenom for treatment of rattlesnake bites has been received by the Bermuda Hospitals Board, a spokeswoman has confirmed.

The precautionary measure came after a reported possible sighting of a rattlesnake in Southampton.

Residents in the area of Gibbs Hill Road remained on high alert this week and one noted being “extra cautious” as she tended her garden in the neighbourhood.

It is understood that the venomous reptile was first spotted by a construction worker on Friday afternoon.

The Ministry of Public Works and Environment said on Sunday that precautionary measures included the sourcing of appropriate antivenom.

A BHB spokeswoman said yesterday: “Bermuda Hospitals Board has received rattlesnake antivenom in its internal dispensary.”

Since the sighting last week, a combined effort to find the snake has been launched with the Department of Environment and Natural Resources joining forces with the Bermuda Aquarium, Museum and Zoo.

A rattlesnake’s bite can be serious, but it is rarely fatal if treated promptly.

Rattlesnakes are ambush predators, primarily feeding on small mammals, birds and occasionally reptiles.

They use heat-sensing pits located between their eyes and nostrils to detect warm-blooded prey, especially in lowlight conditions.

Their rattle serves as a warning signal to deter threats and predators and they will typically only bite when provoked or threatened.

Anyone who spots the snake was urged to call 911.

However, residents are warned to keep a safe distance from the reptile if they see it until authorities arrive.

Members of the public were also warned to avoid approaching, capturing or harming the animal.
