Ughbug...bedbug detector -How does it work?

Easy... push the button and the special frequency ultraviolet light will make bedbug droppings and eggs fluoresce. Find a fluorescent spot and you’ve discovered bedbugs. Use the magnifying lens to identify living bugs as well. Check out your hotel before you sleep in the bed. Use it in dorm rooms, airplane and movie seats, even your own bed. Take it with you wherever you travel.
