Despite our best efforts, bugs sometimes enter the living areas of buildings. Insects often make an appearance around outside temperature changes. While most are harmless, some do harm. Therefore, University Housing has created this bug identification cheat sheet. This will help you identify which insect it is so that we can have Pest Control bring the proper chemicals. For example, box elder bugs look like cockroaches but require a different treatment. It is the same between American cockroaches and German cockroaches. When you see a crawly you would like us to address, try to take a clear picture of it (macro if your phone has that option) or use these pictures to give us more data for our response. Then, place a workorder and attach the picture to the work order.
If you suspect that you have bed bugs, go to your service desk right away and inform them so it can be assessed immediately. Thanks for the assistance!
Bug Identification
Bed Bug
Bed bugs are reddish-brown in color and are about the size of an apple seed when they reach adulthood. Their bodies are flat and oval-shaped. They are most commonly found in mattresses or bed frames. They cannot be resolved without professional exterminator intervention.

Their eyes are large, taking up most of their head. They can range in color from white/yellow to dark brown or black. They are often attracted to lights. They start to appear in late spring, peak in summer, and then taper off as fall approaches.
