The present invention relates to a portable smokescreen insecticide sprayer, wherein: an oil supply container (26) and a medicine supply container (38) are separately configured and if a smokescreen is generated by evaporation while oil passes through a coil type evaporation pipe (34) such that the oil is discharged through a discharge pipe (36), a strong suction force is created within a medicine supply pipe (42) which connects the medicine supply container (38) with the discharge pipe (36), thereby allowing the medicine to be aspirated within the discharge pipe (38) to be sprayed in a state such that the medicine is uniformly distributed into the smokescreen in a particulate state. Thus, the invention: prevents the inconvenience of mixing the oil with the medicine prevents loss caused by the evaporation and carbonization of the medicine and ensures longevity by preventing malfunction of the main components, which occurs due to the toxicity of the medicine or to mucous sediment that is created when the medicine is mixed with the oil, or by preventing the coil type evaporation pipe (34) from being blocked by the medicine.
