The traps work but they are inadequate alone to fight the battle. The first few days they were not trapping any bugs, but once the first few got in, they have done a good job attracting them - stink bugs are drawn to their own odor. I put 2 traps in my 10 X 40 foot vegetable garden and they seemed to slow the onslaught, but they still did not rid enough for the garden to start producing again. The problem is a trap might capture a hundred or even a thousand bugs, but it is just a drop in the bucket relative to the local population.
