Sefton Central Labour MP Bill Esterson urges Formby residents to be more security conscious after a recent rise in burglaries.
Central Sefton Area Committee will hear a report from Formby's neighbourhood inspector that there has been a rise in burglaries in the town due to unsecured doors and windows.
Bill urged people in Formby needed to ensure that they were not leaving the door open to opportune criminals.
Bill said: "I am extremely concerned about this increase in burglaries. Formby is clearly being targeted by opportunistic burglars who have been taking advantage of the warm weather and people being less security conscious as they leave windows open.
"But unfortunately, none of us can afford to become lax when it comes to household security. there are criminals out there who will take advantage.
"This is an issue which the police have raised before. Not too long ago, the police conducted a survey and found that one-third of front doors they tried were unlocked. But clearly some people still aren't getting the message and are leaving themselves open to sneak burglaries."
Bill said the design of some of the PVC doors means that some householders don't realise they are leaving the door open to thieves.
Bill said: "One thing that I have noticed, is that the design of some of these doors is that you can still open them from the outside even though they have been closed from the in. What you have to do is make the effort to lock them with a key - which lots of people don't do.
"So criminals are finding it easy to slip into people's homes because the occupant has inadvertently left the door open.
"So my advice is to always lock the door behind you, keep the key away from the front door to avoid hook and cane burglaries but in a place where it is easy to access in case of emergency and the need for swift escape.
"I and the rest of the Labour Action Team are passing this message on to people throughout Formby and the rest of Sefton Central and I would urge people to advise their neighbours, particularly the elderly."
