The German cockroach is the most pesticide-resistant structural pest, next to the housefly .
Field use and research alike continue to demonstrate that acephate (the active ingredient in Orthene) remains one of the few insecticides to which the German cockroach remains largely susceptible.
Extensive research on insecticide resistance in German cockroaches shows that 51 strains demonstrated resistance to chlorpyrifos -- while only four strains demonstrated resistance to acephate (Orthene).*

Orthene PCO-Organophosphate

Orthene PCO is one of only two organophosphates that remain for the PMP industry. This is important because of resistance problems with synthetic pyrethroids and the need to rotate chemicals. Acephate has never been shown to have resistance. Many people will agree that Orthene PCO will control roaches when nothing else will. Orthene PCO provides quick knockdown and residual that will last 8-12 weeks.

There are a few things that make Orthene PCO unique for commercial use. Orthene PCO controls insects by contact and ingestion. This is the reason an insect cannot develop resistance to acephate. It is a soluble pellet (powder). Orthene PCO leaves no visible residue, will not tie-up with grease and dirt and remains on top of grease and dirt and therefore always present when insects crawl over the surface. Orthene PCO is totally non-repellent. Insects do not know it is there. This means it can be used with baiting programs to get rapid control of infestations.

Orthene PCO also adheres well to stainless steel surfaces. This means it resists washing off these surfaces when areas are hosed down in the evening.

Orthen is water soluble, Not Oil Soluble

In commercial kitchens and other areas that attract cockroaches, there are almost always grease or oil deposits. These deposits can soak up oil-soluble products like chlorpyrifos or pyrethroids -- and compromise their effectiveness.
But Orthene forms upright, spiked crystals -- even on grease deposits. So Orthene stays on the surface to effectively control pests -- instead of soaking in.

Pro Tips

For tough German roach problems, such as those found in commercial kitchens, combine Orthene PCO Pellets with Tekko IGR for optimum control. Gentrol will slow down the roaches' ability to breed while the Orthene kills the existing roaches. Orthene does have a bit of a smell so we would recommend using an odor masker such as Monterey Odor Mask.
