A these traps exceeded my expectations. First, I was able to determine that bed bugs were not an issue. A change of laundry detergent was the root cause of the "bites". Secondly one of these traps caught a small harmless spider who happened to climb a small Incline that happened to be the trap. The outer surface is gritty enough for insects to readily limb and the inner surface is so smooth that small critters cannot escape.
I have not tryed the pitfall apparatus yet, however, I can tell you that nothing has worked up to this point. Where are the scientists of the world. BB's are beginning to be a major issue to our rest. They are more widespread than most think and are not vunerable to any sprays. Last night I finally got some sleep by spraying Deep Woods Off around the perimeter of the mattress. I did not have a bite all night and only got up a couple of times to see if any were on the bed. Entrepreneurs of the world, we need some help here. A remedy could be worth millions on the market!!!
