My chemical wholesale supplier showed me a new commercial bed bug trap a while ago. Apparently you put a concoction that creates Co2 into the trap and put it against the wall in the bedroom and the bugs fall in. It looks quite handsome. But does it work?
Starting about a month ago I began assisting a family with bed bugs that had been unsuccessfully treated by others. One of the tools the previous exterminator used was these handsome Co2 traps. The trap had been placed in the infested bedroom by the head of the bed (optimum placement) and my inspections showed zero bugs.
I left the trap in place by the head of the bed and installed my modified glue board traps under the bed legs. When I returned 2 weeks later there were over 100 bugs on the glueboard traps and still zero bugs in the Co2 trap.
So we learn here that a 50 cent glue board under the bed legs outperforms a $60 contraption by a large margin. Even with 100 plus bugs wandering the room the Co2 trap still caught zero. Beware the miracle bed bug products.
