Insecticides (Wettable Powders)

Wettable powders (WP) are formulated to provide exceptional residual control. The active ingredient is mixed or adsorbed onto a mineral filler (depending whether the active is a liquid or solid at ambient temperatures). Dispersants and surface-active agents are added so that the formulation can be mixed with water for ease of application. This formulation type is especially useful for the treatment of highly absorbent surfaces such as brick, mud or some wood because after application the active ingredient (and filler) is left on the surface as a microscopic, insecticidally active, powder that is readily picked up when an insect walks over it.

The two formulations below both provide extremely good residual control on difficult surfaces where exceptionally long control is required.
