Comments:
This species is a pest in houses, hotels, barracks and other living quarters. It is nocturnal and hides during the day in cracks in walls, under baseboards, in the springs of mattresses and under wallpaper. With modern sanitation it is much less common in North America but it can still be abundant in some areas. They do not transmit diseases and most people react to their bites the same way as a mosquito bite.
