Cheshire Police are urging residents to lock their doors to keep opportunist thieves away.
And now officers want to ensure the public know to keep their doors locked and secure, whether it is your home, shed or outbuilding.
Sergeant Graham Davis said: "There are criminals who specialise in sneak-ins. They don′t have to bother forcing a door or window. They just try doors until they come to one that is open. The longer nights which are coming in make that easier.
"They also provide cover for the more traditional burglar. Again, the first line of defence is locked doors and windows. We also advise people not to leave valuables, or keys, near windows where they can be seen from the outside. It is an added incentive for a burglar if he knows there is something good on offer, before he goes in."
How to keep the thieves away
Sgt Davies also advised homeowners to invest in security lights on the outside of their homes.
"More often than not, traditional burglars target houses while the occupier is out," he said. "It is worth spending a few pounds on time switches to turn some inside lights on as daylight fades. If the house looks occupied the burglar will probably turn away.
"Think about investing in a security alarm system and if you have one fitted be sure to set it every time you go out and when you go to bed.
"Some of the best crime prevention devices are your eyes. Burglars will usually spend time looking round a street to decide which houses are vulnerable. A sneak-in specialist will be ducking in and out of gardens, trying doors.
"If you see anyone acting suspiciously, call police on 101 and report it. You may be doing your neighbours − or yourself- a big favour.”
