The invention discloses an insect disinsection method by using taxis of pests to crops. The method is characterized in that a mode that a raise crop and a bait crop are intercropped or the bait crop is planted around the raise crop is employed to allure control objects to aggregate on the bait crop, then pests are centrally killed on the bait crop, and the pest amount of the raise crop is smaller than that on the bait crop. Compared with the prior art, the method has the advantages that the pests are allured to the bait crop and centrally killed by the feeding taxis of the pests so as to protect the raise crop, decrease the pesticide dependency of the raise crop, reduce the over-standard risk of pesticide residue, improve the quality and the added value of the product, and provide development and guarantee for food from greenization to organification.
