Query: Not impressed!!

Bought this thing out of curiosity to tackle some roach problem but ended up regretting it. No roaches entered the boxes for a whole week (checked everyday) despite the "pheromone formula". It did however start trapping roaches after I added some "bait" (Doritos crumbs). So don't expect it to attract roaches on its own. I gave it 2 stars cos it does work when there's something inside attracting the roaches but I found something similar at my local 99c store that worked just as well.
