Most county health departments have a Vector Control section that may be able to identify your insect for free, if you have found an insect you think is a bed bug or any other insect, actually. Some County Health Departments, like Multnomah have an entomologist who can identify your bugs for free! Imagine how excited I got when I discovered there was a site where you can find your Department of Health for your county.
Turns out the National Association of County and City Health Officials has made it easy to find your state and your county so you can inquire. They may be able to direct you to treatment options you didn’t know you had if you are in subsidized or low-income housing. It’s free to ask is my motto!
