Nobody wants that, so here are a few snazzy ideas to keep the unscrupulous at bay:
Keep up-to-date with your garden maintenance
Nothing says 'we're not home' than an overgrown lawn, so keeping that trimmed and terrific will give the allusion you're still on top of it.
Keep a car in the driveway
If you're friends with your neighbours, they can be a godsend because all you need to do is give them your car keys and they can alternate the car's position every second day or so. They don't need to go inside, but just to give the allusion you're around.
Pop a light on a timer
This cheeky trick is one of the oldest in the book. A light on a timer can make sure the house is lit up before it gets dark and is off at a reasonable bed time to give anyone casing the place the false sense of someone being inside. It can be a game changer!
It doesn't even have to be hard-wired to the home and you can use a portable lantern like the super stylish below option from BHG Shop that does just the same thing. Perfect for a long weekend! Get your own from BHG Shop here.
Divert your mail
Know what else makes it obvious you're not home? Mail hanging out of the letterbox.
Australia Post now offers a free mail and parcel collection service, so looking into that will save you having to rope-in any neighbours or your Mother-in-law.
Don't forget your blinds
If you can't get or install programmable window shades and blinds that go up and down remotely or at preset intervals, then angling them into a wall or closing them completely is a good option. That way no one will ever be able to see whether you're in or out!
