This is one of several compounds used for vector control of Triatoma. These insects are implicated in the transmission of Chagas disease in the Americas.[6] Pirimiphos-methyl can be applied as an interior surface paint additive, in order to achieve a residual pesticide effect.
Pyrimiphos-ethyl is a related insecticide in which the methyl groups are replaced with ethyl groups.
