The Science

DEMAND DUO provides rapid knockdown of even hard-to-control pests like German cockroaches while continuing to work for you up to 90 days. Compared to many products on the market, DEMAND DUO outpaces other formulations’ knockdown capabilities while also outperforming on longevity. It does not matter if DEMAND DUO is on a porous or non-porous surface, it performs strongly on almost all surfaces due to the unique ZC formulation.

The longevity of DEMAND DUO is due to the unique ZC formulation that stays stable on surfaces; the quality milling and size distribution of the SC component, combined with industry-leading iCA encapsulation, makes it effective at maintaining control by ensuring a gradual diffusion over a long period of time.

Tips for Use

  • DEMAND DUO is diluted with water for application using hand-held or power-operated application equipment as a coarse spray for crack-and-crevice, spot treatments, perimeter treatments, and surface treatments.

  • Initial clean-out rate allows for a higher dose in difficult and high pest situations.

  • Maintenance rate provides control, keeping areas clean and clear of pests in a very economical manner long term.

  • Convenient single water rate of 1.1 oz. per gallon of water for all uses, with no need to switch between water volumes to account for surface type.

    This works really well — ant eradicated!

    By Tad on 10/02/2020

    I applied this last month and was amazed! Whereas a few days before where my patio was crawling with black carpenter ants, after the application of this, they were entirely GONE. I definitely recommend and will keep using to keep outsiders from taking over my patio or house.

    This stuff works!

    By Chris on 10/23/2020

    I moved into a new home and there were quite a few bugs that would find their way indoors. I didn’t mind but needles to say my wife was ready to move out anytime we saw a spider. I found this spray and went around the perimeter of my home and boom no more bugs. The difference was apparent right away and with minimal work. Get yourself a cheap sprayer and eliminate your bug problem in under 20 minutes

    Great product.

    By Mark on 10/23/2020

    We stopped paying for pest control several years ago and have not seen a big in our house until about a month ago when the weather turned cooler. I ordered the customized pet control system. It arrived on time, I administered it and haven’t seen a big inside since. Great product, great service and always more economical for me!

    Since spraying I haven’t seen very many spiders and also seemed to knock down the amount of elm bugs.
