Depends on the type and some work in more than one way. For example boric acid is a stomach poison most bugs ingest when they groom, however, dusts can also clog the spiracles (holes in abdomen they breathe through) or dry out their exoskeletons (dessicants) Organophosphates act on their nervous systems and eventually they freeze (are unable to move) and starve. Contact sprays are simply absorbed through their bodies in most cases.
