The Gotcha Sprayer is the perfect way to spray aerosol cans from a extension pole. Simply insert a can of aerosol spray, attach the Gotcha Sprayer to an extension pole (each sold separately) and you're ready to spray. The Gotcha Sprayer will work with any standard aerosol spray can. The Gotcha Sprayer can attach to extension poles up to 24ft long to reach those high eaves. No more climbing on ladders or telling the customer you can't reach those high peaks. It can be angled to reach under decks without having to crawl in the dirt or getting trapped in tight spaces.
