Bengal Roach Spray is a permethrin based product that uses a unique dry spray to get into deep crevices and cracks to control roaches where they live. Simply place the extension tube that comes with the can into the top of the can and press the spray button. This product is in a spray can of it's own, so it cannot be used in a fogger. The product will leave a residual and it can be reapplied every 4 weeks when used as directed.
  One of our roach control kits would be recommended for roach control. These professional kits includes 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.   Here is a link to a great article that really goes into depth in explaining a roach control program.
