Adder sightings in Carmarthenshire prompt warning not to disturb them
People have been warned not to disturb adders after sightings of the venomous snakes.
The reptiles have been spotted in Parc Stephens and Glan yr Afon in Kidwelly, Carmarthenshire.
Kidwelly Town Council said adders are also "very likely" to be found in Kidwelly Quay and on Mynyddygarreg mountain.
It reminded residents that they are "legally protected species and they will not bite unless provoked".
It also urged people to keep dogs under supervision.
Medical or veterinary advice should be sought after bites, it added.
Llanelli AM Lee Waters said he had been in touch with a "concerned resident" who described an "unusually large number of adders seen around Kidwelly".
He added: "I contacted the town council who are aware of this and they've agreed to put up warning signs in Parc Stephens, Glanyrafon, The Quay and Mynyddygarreg.
"Adder bites can be nasty for us and our pets, but are easily treated, so keep an eye out if you're in the area."

Last year, the Amphibian and Reptile Groups of the UK (ARG UK) said a "whole generation's attitude" towards the venomous snake had to change.
Dr Sam Langdon, from ARG UK, told BBC Wales adders were disappearing across the UK, leaving "little pockets" where the creatures can be spotted.
She said persecution - alongside loss of habitat - was a key reason behind the snake's decline.
Wales is seen as one of the reptile's remaining strongholds.
