Initially, it will be very difficult for you to realize bedbugs have come home to roost in your home. When they first arrive, they are very good about hiding their whereabouts as they set up home. The first sign you have a bed bud problem might well be when they start biting you or your family members.
When you get that first indication the bugs are among you, you need to find out where they are nesting. There are two signs for which you can be looking. First, you should be looking for larger concentrations of bugs. That’s a good indication the nest is nearby. Second, these little nuisances will give out a “musky” odour when there is a large concentration of them in a small area.
Areas of concern would be baseboards, furniture cushions, under the mattress, electrical outlets, areas of concentrated trash (stack of newspapers, etc.), and wall and furniture cracks.
