S-Methoprene is an Insect Growth Regulator (IGR), meaning that it halts the growth of chitin, the substance that creates the exoskeleton in insects. IGRs are effective against developing insects but not against adult insects with already developed exoskeletons. Because of this, IGRs are used to prevent an extended infestation. Since mammals do not produce chitin, insect growth regulators have little effect on humans. According to EPA S-Methoprene has a very low acute toxicity. [source]
S-Methoprene is listed as a least-toxic chemical control by the Integrated Pest Management Practitioner. It is listed on City and County of San Francisco Integrated Pest Management Program 2007 Reduced-Risk Pesticide List. [source] And it is listed on EcoWise Certified IPM Program Materials List.
