Pictures of Bed Bugs in a Mattress

Do you know what a bed bug mattress infestation looks like?

Being able to identify a bed bug problem can help keep you and your family safe at home and when traveling. These pictures will help you spot some of the tell-tale signs of a bed bug infestation.

Bed bugs leave dark fecal stains on mattresses and other places they infest. If you don’t see any bed bugs, you still might see their feces.

Bed bugs move through 5 stages of growth on the way to maturity. At some point during each stage they will become too large for their current exoskeleton. When that happens, they will shed their exoskeleton and grow a new one that is larger. You may see these molted exoskeletons close to where bed bugs hide.

Notice that the bed bugs seem to be concentrated in the seam. Bed bugs like to hide in seams, folds, creases and crevices. Always check these areas.
