And the link to what they lok like. Once you have seen a couple, the light brown, almost translucent color is easily recognizable. They do not like light but the light bulb in the attic only works for those in the open when the light is turned on. After that, you will find them between all sorts of objects. I have a great respect for this creature, want nothing to do with dealing with the bite.
