The invention relates to a cyhalothrin and bendiocarb-containing composition and application thereof and provides a pesticidal composition for controlling health mosquitoes, health flies, blattella germanica, solenopsis invicta buren and other health pests, wherein the mass ratio of the cyhalothrin to the bendiocarb is 1:99-99:1. The contained two pesticides have the advantages of different toxicology mechanisms, independent function, synergy during compounding, and capacity of improving the effect of controlling the health pests; the composition can control each metamorphosis stage and developmental stage of the health pests in the whole life history due to related coaction of the pesticides in the pest bodies; and products such as mosquito coils, insecticide aerosol, insecticide electrical mosquito mats, insecticide baits prepared from the pesticidal composition have the advantages of rapidness for killing the pests and durable pesticide effect, and can ideally control the health pests with resistance to pyrethroid pesticides.
