Thanks to the University of Kentucky & their fantastic department of entomology we get amazing technical data like this. What you see is a 1st stage bedbug (nymph) actually feeding. Notice how small and opaque it is? That quickly changes as it takes its blood meal and becomes that mahogany red color. In the 1st Nymphal stage they are small enough to fit through a zipper!
It takes bedbugs anywhere from 3-15 minutes to feed or until full. This video was sped up so the feeding effect can be seen from start to finish in a short period of time.
