Pests are controlled by applying to the location of and/or to the path traversed by the pests a composition comprising urea and sulfuric acid in which the urea H2SO4 molar ratio is less than 2. Novel compositions useful in such methods are also provided and comprise the described combinations of urea and sulfuric acid dispersed in a hydrocarbon oil. The novel method and compositions are particularly useful for controlling plant pests by applying the useful urea-sulfuric acid components to the plants or to the vicinity of plants occupied or tranversed by such pests.
