What is the difference between granules and liquid spray?
A granular form of a pesticide has the active ingredient pre-diluted and impregnated on clay, paper or other sand like particles. Granules can be equally effective to sprays in damp winter conditions for a variety of crawling perimeter pests (ants, earwigs, millipedes, Oriental Cockroaches, etc.). Sprays are most effective on contact for ornamental and turf pests such as caterpillars, aphids, scale, whiteflies, and most spring and summer garden pests.
