In most home break-ins, thieves simply walk in an unlocked door. The number one tip for DIY security is simply...locking the doors.
Here are some other tips—ranging from cheap and easy to a bit more involved—to help make your home less appealing to burglars.
Fortify the doors
On doors, use a dead bolt in addition to a knob lock. For extra security, add a tiny lock that covers the dead bolt's screws so it can't be picked.
A common method of entry is to kick in the strike plate, the panel that holds the lock or latch bolt in place. For more protection, install a heavy duty strike plate using extra-long screws.
Install strong doors in a solid frame. A high-tech lock is useless on a flimsy door.
Put a peephole in the door.
Use landscaping for home security.
Choose plants that don't obstruct a clear view from the street—these give burglars privacy and added time to break in.
Remove climbable trees that allow easy access to second floor windows.
Plant thorny plants under windows like cactus, holly or roses. On fences, try blackberry vines which are thorny and grow quickly. A local nursery can give you good suggestions for your neighborhood.
