The invention discloses an azadirachtin-attapulgite compound pesticidal granule. The pesticidal granule comprises azadirachtin and attapulgite the ratio of (0.03-5):(80-90). Since azadirachtin molecules comprise unstable groups such as ester groups, epoxy groups, alkenyl ether and the like, the azadirachtin is easily decomposed under the conditions of ultraviolet light, sunshine and high temperature and is decomposed and fails in 5-8 days. The pesticidal granule has the following advantages: by means of combination of the azadirachtin and attapulgite pesticide carrier, the pesticidal granule not only can kill plant pests, but also can be used for preventing and curing ectoparasites of animals; the pesticidal granule has wider pesticidal spectrum and environmental-friendly characteristics of high efficiency and no residues; and the release time can be greatly delayed, thus the pesticidal granule is a long-acting pesticide.
