D-Fense NXT is labeled for bedbugs and can have a residual up to 6 months. Per the product label:  Remove linens and wash before reuse. Take bed apart and treat cracks, joints and interior of framework. Treat mattresses and box springs; especially tufts, folds, and edges. Also treat picture frames, baseboards, moldings and all cracks and crevices in the room. Allow to dry 4 before remaking bed. Do not use in patient rooms in hospitals and nursing homes for treatment of bed bugs. May be used in conjunction with a bed bug proof mattress encasement. To treat furniture, such as couches and upholstered chairs, turn the piece upside down, lift the dust cover from the bottom and spray the interior frame. Replace the dust cover after frame treatment and turn piece right side up. We suggest also applying the products in one of our Bedbug Kits. Please take a few moments to review our treatment article/videos on How to Get Rid of Bedbugs for a successful eradication program.

D-Fense NXT  is a ready-to-use product that contains residual insecticide and two Insect Growth Regulators, so it will continue working after it dries. While this product is labeled for use on exterior surfaces such as along the foundation, on window sills, and other areas where insects may harbor, we would not recommend a ready-to-use product like this for the longest residual. You would get much longer residual outdoors with a liquid concentrate deltamethrin product such as Suspend Polyzone. D-Fense NXT can be used to control German Cockroaches, but we would recommend using a roach bait gel along with spray for more complete and faster control. We recommend you take a few moments to review our Roach Treatment Guide here for more tips on how to eradicate this pest.
