The Exacticide Webster Dust Applicator is a great dual-purpose dust applicator accessory for the Exacticide. It can be used both to clean webs and leave dust residue at the same time. Dust injected from the Exacticide into the six manifold ports is evenly distributed into the duster head. Press the remote control and prime the duster head before use. Best used on eaves, shrubs, wall ceiling junctions, mattresses, and drapes. Deals with insects such as bedbugs and spiders. This part includes the blue Webster dust head, manifold, and hose.
