If the pesticide is registered by the EPA it will have to be labeled for misting system in order to be used. The label is the law and any claims made not found on the label is in violation of the law and would be false claims. Products that read Safe. All Natural, Will Not Harm and Organic are classified as a 25B Exempt Product which do not require EPA Registration unless you want to register the product with the EPA so you do not have to list the inert ingredients on the label. Demon works to a certain point on spiders, the problem is Demon also leaves your house covered in a white powder which is very tacky on a brown house. Demon does nothing for future spiders because once it dries a spider can walk through the poison because they do not put their feet in their mouth like a roach and other pest for the product to kill them. I would be more concerned with the ingredients that make up demon than those that make up what is used in misting systems. Misting System uses Pyrethrum and PBO, Permethrin and PBO or Pyrethrum, Permethrin and PBO. Example of these would be Riptide which is Pyrethrum and PBO, Vector Ban Plus which is Permethrin and PBO and Pyranha 1-10 HP which contains all three active ingredients. True statement is Pyrethrum comes from Flowers harvest in Africa and and other Countries and is a natural pesticide, however once PBO is used to make it work it is therefore no longer All Natural. What is PBO - Piperbonyl Butoxide that is used as a synergist additive to super-charge performance of insecticides allowing you to use lower dosage rates with an enhanced product. Can also restore the effectiveness of a product in some cases if pest-resistance has been developed. Synergizes many insecticides, including pyrethroids, imidacloprid, carbamates, rotenone, and others.
