Residents living in an area where 300 burglaries were committed within three months are to be issued with security leaflets styled like large footprints.
The new anti-burglary leaflets being sent to homes in Thames Forest
Beat officers, burglary scene investigators and patrol officers will be distributing the black and orange leaflets in Thames Forest, Berkshire.
The move, by Thames Valley Police, comes after research showed 32% of the burgled homes were poorly secured.
From 1 May to 31 July, 125 properties in Maidenhead were targeted.
Windsor had the second highest number of burglaries recorded with a total of 72.
Meanwhile, 69 premises were targeted by thieves in Bracknell Forest over the three-month period.
Community partnership Inspector Pete Carter, of Thames Forest police area, said: "It is important that homeowners work with the police to help reduce burglary and make life harder for opportunist burglars.
"Whilst I completely understand that there is a need to open windows and doors especially during the hot weather, it is not wise to do so whilst perhaps sitting out in the garden, completely unaware of who is entering your house via the front for example.
"Neither is it ideal to leave windows unlocked whilst sleeping at night."
