Use multi locking on side & rear doors

Fit window locks

Use special locks to prevent your patio doors from being levered

Cut back overgrown bushes and trees in the front garden to make sure the front of the house can be seen from the road - the majority of burglaries in the US happen by the thieves gaining access through the front door
