I ordered the pheromone roach traps because I had seen pest control servicemen use them elsewhere with great effectiveness. Apparently, though, the roaches in MY home simply aren't attracted to the scent. The traps I put out remain largely empty while I daily chase and swat at roaches that roam with impunity in, over and under my kitchen cabinets. Did I receive a batch of old traps in which the pheromone scent had faded away? Or are my roaches simply not interested in the opposite sex?
