Most pest problems hide on the undersides of leaves, right where standard spray bottles fail. When you tip a normal bottle backwards to spray underneath a plant, the internal straw sucks air, and the spraying stops. This bottle-top pressure sprayer solves that completely with a flexible gooseneck nozzle.

You simply screw this pump head onto a standard 1.5L soft drink bottle, build up a little pressure with the manual push-pull handle, and bend the nozzle tip upwards. You get a continuous, adjustable mist exactly where you need it, while the bottle stays perfectly upright. It’s an inexpensive, incredibly practical tool for mixing small, fresh batches of neem oil or foliar fertilizers.
