It's well-worth your time and money to make a burglar's job very difficult. Employ the following home security tips:
Lock up! How many times have you read about a home intruder who "entered through an unlocked window"? Keep your windows and doors locked as much as possible.
Deadbolts. A deadbolt makes an incredible difference. Even a "determined" thief wants a quick, easy job. A decent deadbolt is about $25; you'll get what you pay for. Lock it when you're at home, too.
Home security. You can even do this yourself. A cheap system will sound an alarm that no burglar will want to stick around for. You can install a basic system including a keypad and door sensors for $25 online. Add on features like wireless keyfobs, motion detectors, etc. However, if the money is there, invest in a monitored system. The monthly fee is cheaper than you think.
Use curtains/blinds. A potential burglar won't be interested in your home if he can't see in. When you're gone during the day, close the curtains/blinds unless your plants need the light to survive. If you're home and want to admire the view, at least close the curtains on windows through which you're not admiring any view. Never leave them open once dusk hits.
Shrubbery. If you absolutely must have shrubs near entry points to your home, then make sure they're thorny so that a burglar doesn't hide in them. If what's already there isn't thorny, have it trimmed down so that a burglar can't hide there.
Sliding door security. Place a wooden rod in the door track frame.
Be safe. With a safe, that is. A fireproof safe is less than $40. Until you get a safe, put your jewelry in a place a burglar would never look: like a covered Styrofoam cup next to the mouthwash bottle.
Don't forget the garage. Keep the garage door closed at all times, even if you have an in-and-out lifestyle. You can buy a garage door timer for under $40 that automatically shuts the door after a predetermined time period. But if you want to keep it open, the device has a manual override.
