Burglars see open doors and windows as an opportunity during hot weather, according to the police.
The public are being warned that while they might want to let in a breeze, they run the risk of being burgled.
"Open doors and windows are an open invitation to burglars, make sure yours are secured," said a representative for PSNI Magherafelt.
"Valuables left on display in cars are also extremely tempting for an unscrupulous thief. Never leave your handbag, electronics or other valuables in plain sight, put them safely away."
