Simply pour 4 ounces of Archer in the bottle of Outdoor Flea Spray and apply the insecticide and Archer at the same time. Be sure to follow all instructions and cautions listed with any insecticide. This means long-lasting flea control in brightly lit rooms and rooms sunlit through open windows. Obviously, Precor is not designed to be used outdoors, but in the house, and outdoors is where much of the flea development typically takes place. This gives Archer a tremendous advantage over the old first-generation IGR, Precor.
Program is an interesting product that came on the market several years ago.
When a larva needs to break out of the egg, it uses an egg tooth made of chitin. Program is given to the dog or cat orally where it is absorbed and enters the bloodstream. The blood is ingested by the female flea when the flea bites the dog and as the egg is produced, it causes the dysfunction in chitin formation and the ultimate inability of the egg to hatch. We do carry it for those who prefer to use it. But, for it to be truly effective, every pet in the household should be given an appropriate dosage every month.
