My friends & family always as what do you look for when you inspect for bedbugs? Part of this is that they want to know so they can do the same when they travel to hotels. The honest answer is that I look for the insects or their signs. Their signs are blood stains or fecal matter which often are like black ink stains on fabric (blood goes black without oxygen). This is often located where the hosts (people) sleep or rest and this means mattresses, box springs, chairs, & couches get extra special attention. Another sign is cast skins as bedbugs molt to reach the next stage in their development. The last item is live bedbugs in all stages. This is often easier said than done! Bedbug eggs are the size of a pin head and nymphs in stages 1 & 2 are so small they can fit through a zipper + they are opaque in color. Once they reach the 3rd developmental stage they do start to resemble a bedbug.
Picture number one shows a bedbug infested bed skirt and you can see adults, molted skins, stains, and nymphal stages. This is a mature infestation, at least six months old. These are easy to identify visually plus they emit a sweet musty smell like fresh raspberries or almonds. The 2nd picture is bedbug eggs on a mattress. As you can see the eggs are so small they are the size & color of the thread on the mattress. There are adults present but the eggs are so very hard to find.
How do you inspect for bedbugs? You hire EHS!
