D-Fense NXT is an insecticide aerosol formula. It is known for its highly effective action against a number of insects.

The formula is famous for its combination of three powerful active ingredients.

The mixture of Novaluron, Deltamethrin, and Pyriproxyfen gives the insecticide three modes of action.

As a broad-spectrum insecticide D-Fense NXT provides a quick knockdown and kills insects on contact along with providing long term residual control against them.

D-Fense NXT contains 2 IGRs (Insect Growth Regulators) which effectively break down the lifecycle of insects for up to 180 days.

Not only does the formula control cockroaches it prevents the eggs of bed bugs from hatching thereby controlling re-infestations.

D-Fense NXT also prevents insecticide resistance in order to provide continuous resistance.

D-Fense NXT is suitable for both indoor and outdoor use as well as for spot and surface treatments.

The aerosol can of D-Fense NXT comes with the flip-up actuator and a 360-degree valve. The 15 oz. canister also features ridges for an easier grip and to avoid slipping.

Properties of D-Fense Nxt

D-Fense NXT is famous for its three-way ingredient action. The insecticide mixes a residual insecticide active ingredient called Deltamethrin, with 2 IGRs (Insect Growth Regulators).

The IGRs called Novaluron and Pyriproxyfen are responsible for breaking down the bed bug life cycle which in turn prevents the pest from shedding.

The inhibitor in D-Fense NXT prevents bed bug eggs from hatching and the hormone analog impairs their mobility such as the climbing and gripping ability.

The physiological effects created by D-Fense NXT in bed bugs result in their death.

Will this kill bed bugs?

YES YES YES Good luck, I feel your pain. I had a horrible infestation because my tenant let them multiply for almost a year before the found their way into my apartment. What a nightmare, There is not enough room for me to tell you all the things I tried and all the money I spent.

Is it safe to use with Carpet and painted surfaces around?

Yes, it is. However, you should always read the label before spraying.

What is best for Asian Beetles and when to spray and how often?

The D-Fense XT worked like a charm! Sprayed it only outside around windows, doors, foundation, and deck but they started dropping immediately and we have, literally, thousands of dead Asian beetles and hornets! Will do spot treatments around inside of windows this weekend and expect great results but probably a lot less to kill now

Does this help with mosquitoes?

The documentation does not mention mosquitoes as one of its targeted pests. This product is a liquid that you would spray around the perimeter of your building or structure. Not sure how this application would be able to target a flying pest.

Will D-Fense NXT work for cheyletiella mites, bird or rat mites?

D – Fense NXT is not labeled to for cheyletiella mites, bird or rat mites. We do not offer any products that are specifically labeled for these species. We recommend that you consult with your local cooperative extension office for recommendations and positive pest identification. While awaiting the pest id, you can vacuum, steam, use encasements on furniture and launder belongings such as linens, clothing etc in the washer and dryer. We do offer Sterifab that can be applied to upholstered surfaces, inanimate objects, mattress, etc. for a contact kill.
