The active ingredient in the RoboSol Insect Killer Aerosol Control is PYRETHRUM. Pyrethrum is prepared from daisy-like flowers of Chrysanthemum Cinerariifolium and is the world?s foremost natural insecticide. Pyrethrum possesses a unique combination of insecticidal properties which have made it the most useful all round insecticide available today. These properties stem from the fact that pyrethrum contains not one, but six distinct related insecticidal ingredients called Pyrethrins. Pyrethrum forces insects to escape to a source of light, which is an advantage because flying insects, will not die on any food you may be preparing but will be found on window sills or will escape through the window if open. - Do not spray directly onto cold blooded pets, our pyrethrum solution is harmful to cold blooded otrganisms.
