The warning from Police Scotland follows a number of sneak thefts in the Stewarty and Newton Stewart areas.
Constable Clark Logie said: “Thieves and criminals are always looking for the easy option. If they find an insecure property, they are more likely to target that property than a property where all the windows and doors are closed and locked.”
Suggestions to deter criminals include the installation of security lighting and alarm systems; asking a trusted neighbour to watch your property; and considering joining or starting a neighbourhood watch scheme.
Other options include leaving lights and radios on a timer when the property is vacant, keeping valuables and car keys out of sight and ensuring all sheds and outbuildings are locked.
PC Logie added: “We would also look to our communities for information. We would ask you to be vigilant for any suspicious persons or vehicles that you see in your area.
“If you see something that raises your concerns then we would ask you to contact the police immediately and not to wait. We would rather attend a call and find out all is well, than receive the information too late and not be able to take any action.”
Any residents who are concerned about the security of their homes are asked to contact Police Scotland on 101, who will arrange for a suitably trained officer to carry out a security survey free of charge.
