bed bugs or bat bugs?

If bed bugs weren't enough, bat bugs are very similar in appearance and behavior and hard to tell from a bed bug. Bat bugs are transparent they go from beige to dark brown after a blood meal. Like a bedbug their mouthparts are made for sucking and piercing. Bat bugs will make humans their target once a bat infestation has been cleared and there are no more bats for them to feed on. http://www.catopestcontrol.com
