The numbers stamped on the case of Roach Pheromone Traps (M330) indicate the year, day of year, and shift the product was made. For example, "172611" indicates 2017, the 261st day (Sept 17), and 1st shift.
The Roach Pheromone Traps (M330) - CASE (96 traps) are only available in the case of 96. An alternative would be Trap A Roach Hoyhoy Cockroach Glue Trap, which comes in a pack of 5 traps. These use a food bait rather than a phermone.
One of our roach control kits would be recommended for roach control. These professional kits include non-staining, low-odor concentrated insecticide for spraying the outside perimeter of the home and inside underneath appliances, behind cabinets, under toilets and sinks, etc. You'll also get Roach Bait Gel to help get rid of those roaches that like to hide. Baits can be applied up high in the kitchen in the corner of cabinets and in cracks and crevices in kitchens and bathrooms. The bait contains a slow-acting poison that attracts and kills feeding roaches, who also spread the bait to other roaches by contact or by sharing food. Finally, an Insect Growth Regulator is offered which will stop roaches from laying eggs, helping to halt the infestation. The combination of an IGR with roach bait is a highly effective roach control strategy that is widely used by pest control professionals. The insecticide must be applied with a 1-gallon pump sprayer.
