A fifth of all burglaries in Northamptonshire in the last year happened because victims left doors and windows open and unlocked, police have said.
Northamptonshire Police today released the stat as part of a drive to ensure residents do not fall victim to predatory and opportunistic burglars during the summer months.
It also comes amid an alarming spike in the number of recorded burglaries across the county.
Detective Inspector Nick Lyall, burglary lead for the police, said: “These types of offences are preventable and we encourage people to take some simple steps to make life harder for thieves.
“We appreciate that we repeat this message year after year, but we tend to see an increase in burglaries at this time of year as a result of people leaving windows and doors open while their property is left unattended.
“Many burglars are opportunists - they will take advantage of an unlocked door or window.
“It may seem obvious advice but it’s important to get into the habit of locking all doors and making sure all windows are secure every time you go out and when you go to bed.
“Items that can be stolen easily, such as car keys, wallets and phones, should be kept in a safe place, out of sight and away from windows and doors.”
Operation Guardian continues to target offenders involved in house burglaries.
In the last 12 months, officers have executed 303 warrants for theft offences and have made 636 arrests relating to house burglaries.
