SCIENCE DAILY - $1 HOMEMADE BED BUG CATCHER INVENTED BY SCIENTISTS full article
Here's how to make one:
• Cut four pieces of rough-surfaced tape. Each piece should be at least as long as the wall of smaller container is tall.
• Evenly space and firmly press the four pieces of tape vertically on the inside surface of the smaller container. The tape allows the bugs to escape the small container easily and fall into the space between the small and the large container wall, where they are trapped.
• Wrap tape around the exterior of the larger container from the base to its upper edge so the bedbugs can enter the trap easily.
• Glue the smaller container onto the center of the bottom of the larger container.
• The traps work best if you apply talc, including baby powder, to the space between the small and large container walls to make it harder for the bugs to escape. Many people use incorrect methods to treat bedbugs. Koehler advises against using flammable liquids, mothballs, treating mattresses with pesticides and using bug bombs.
