Beg bug eggs and early stages are lighter colorer and almost white which shows up better on a black surface such as the Blackout Bed Bug Detector than a lighter or white surface.
We apologize but we do not have a dimensional drawing for the Blackout Bed Bug Detector. The height of the inner wall is 3/4 inch and outer wall is 1 inch. No matter the height of the walls it is designed to trap bed bugs so it is generally not a questionable concern.
There are 12 pieces in one package of Blackout Bed Bug Detectors.
The Blackout Bed Bug Detector will not be effective if they do not enter the trap; this is a monitoring trap to help determine level of infestation and from where the bed bugs are traveling. We recommend encasing your mattress and box spring if the bedbugs are already inside the mattress. You can also treat with Steri-Fab and Bedlam. Steri-Fab is applied to the mattress and box spring. Once dry, you can spray Bedlam around the edges, tufts, folds and seams of the mattress.
