Bed bugs know how to hide. If you have a bed bug infestation, the only sign might be the bites you are getting each day or night. Imagine your office, now think of all the places you could hide a flake of oatmeal and you will begin to get the idea. The same can be said of your bedroom. Bed bugs are better at hiding than you are at finding them.
They can hide where you will never see them. They can climb deep into electrical outlets and hide in the voids within your walls. If there is a tiny hole in your box springs they will climb inside. Wood joints in your desk or nightstand will allow a bed bug to slip within and disappear. If you are getting bit and you notice the telltale spots of brown blood on your sheets, you know you have a bed bug problem.
