Cancel your mail and newspaper. Mail and newspapers piling up will be noticed. Filling out a simple form with the post office and calling the newspaper circulation department can put a hold on delivery until your return.
Postpone parcel deliveries. If you are expecting a package, contact the sender to postpone the delivery until you return. If there is a large box on your front steps for a few days, it is only inviting a potential burglar to investigate its contents and realize you are not at home
Imitate everyday habits. Use timers on your lights or leave some window shades down to give the impression that someone is at home. If you normally have a car parked in your driveway, ask a neighbor to park their car there.
Keep your lawn mowed. The lawn will grow while you are away and this can signal anyone driving by your home that you are not there to take care of it. Hire someone to mow it for you if you will be away for an extended period of time.
