D-Fense SC Insecticide


D-Dense SC is a low odor white liquid which is mixed with water and sprayed for pest control. D-Fense SC is a micro-encapsulated concentrate and due to this traits treatments of D-Fense SC will lay on surfaces better than emulsifiable concentrates and have a longer residual.


D-Fense SC can be applied as a barrier treatment around the perimeter of the home to creating a wide band of treated surfaces to stop invading pests from moving in. It may be necessary to spray the entire side of a building if there is worry of a severe infestation. D-Fense SC can also be utilized in areas where mulch, turf and cement meet.

Inside the home D-Fense can be used for a wide range of pests along baseboards, on carpeting and in crawl spaces.


D-Fense SC contains deltamethrin which is a very very efficient active ingredient that can be used to treat a very broad range of insects. A 16 oz bottle of defense SC can make about 18 gallons of finished spray.

Best insecticide I've ever used. I'm actually looking forward to boxelder bug season.
This product works great. We had a grasshopper infestation that was devestating our landscaping. I treated once a month ago and it's still working. It killed all grasshoppers that entered the treated areas and formed a barrier that is still keeping them out of our yard. Best of all its safe to use around pets. We have three small dogs that were eating the dead ones with no harm to them.
