DALBY property crime rates have more than doubled in the past two months, with youths ramping up crime rates.
Police figures show officers dealt with 83 property offences in September, more than double the 37 reported offences in August.
Most offences are opportunistic and petty in nature, but youths are believed to have caused more than $60,000 damage to a church and $20,000 to a bridge.
In some alarming cases, residents were in the backyard while the youths entered the house and took items.
Known offenders are as young as 11 years old.
Dalby Senior Sergeant Terry McCullough said police had been dealing with a spike in property crime in the past month, most of which was avoidable.
"It's unusual to have this sudden spike and it seems some people have moved here from elsewhere, bringing their offending behaviour with them," he said.
"I think the days when Dalby is a sleepy country town where people can leave their cars and houses unlocked are gone," Snr Sgt McCullough said.
"People need to lock up, even when they're home."
