There are many modes of action. Disruption of the nervous system, digestive system, circulatory system and reproductive system are common.

Cumarin/Warfarin products prevent normal coagulation of the blood and the "pest" bleeds out internally.

Nolobait contains a fungus that prevents the "pest" from effective digestion and the dead are eaten by the living causing a cascade effect as the fungus is consumed over and over again.

Many of the anhelminthics used to worm livestock cause paralysis and the "pest"is expelled with normal waste.

Phosphate based products affect reproduction.
