PRODUCT DESCRIPTION: Duster used for applying insecticide dust to cracks, crevices and other areas where targeted pests are located. It features a large dust holding tank, works by pumping and can displace a lot of dust rapidly if needed. It comes with several nozzles which are stored in the handle including one with a wide opening, one with a smaller opening and then a few really small tips. It also comes with an extension that has lateral dispersion. This tool is great for when you need to do a lot of dusting and don't want to spend all your time filling the duster. The Hand Dusters we featured earlier will do most jobs but their small holding tanks mean that you will need to fill them often when you intend on doing a lot of dusting. The Long Reach Duster also comes with several extensions which can be placed at the nozzle so that you can effectively treat much higher then with the standard unit. It also has the ability to apply dry bait so it can handle many more jobs then the standard Dust-R. Of course, you don't need to use it with the extensions if not needed. With the Extensions all connected, this unit measures just over 10 feet long! This means that most people can easily treat application sites which are 15 feet high and still not need a ladder.
