Wildlife experts have said there have been no further signs of a mouse in one of the Isles of Scilly.

The Isles of Scilly Wildlife Trust said it had conducted an “intensive incursion response” with the Royal Society for the Protection of Birds (RSPB) since 31 October, when probable signs of a mouse had been found on St Agnes.

Mice and rats were previously eradicated from the island as part of measures to protect its population of storm petrels as they would be considered likely to eat the birds’ eggs, the RSPB said.

The trust said it would increase monitoring and reduce its use of rodenticide until the new year when it planned to stop the operation.
