Arena 50WDG is not labeled to be used as a crack and crevice treatment indoors. We recommend using one of our Roach Control Kits
that includes 1 packet of Demon WP Insecticide (which makes 4 gallons of finished solution) for spraying the outside perimeter of the home and inside underneath appliances, behind cabinets, under toilets and sinks, etc. You'll also get 4 x 35 gram tubes of Invict Gold Roach Bait Gel--one of the best roach baits on the market. Invict Gold 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, 20 Gentrol Point Source stations provide an IGR (Insect Growth Regulator) that 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.
