N-lower alkyl neoalkanamides of 1 to 4 carbon atoms in the lower alkyl thereof, and of 5 to 14 carbon atoms in the noealkanoyl group, e.g., N-methyl- and N-ethyl neodecanamides, are new compounds which have insect repellent properties, being especially effective against cockroaches, e.g., the German cockroach. However, they are also useful as repellents for other insects, including, for example, American cockroaches, mosquitoes, flies, fleas, ants, and lice. The most effective of the described amides for insect repellency are normally liquid and are sufficiently volatile to be detectable in air by insects. They may be applied directly to surfaces to be treated or they may be incorporated in detergent compositions, such as laundry detergents, floor and wall cleaners, rug cleaners and shampoos, hair shampoos, and liquid and bar soaps, and have been found to be sufficiently substantive to the substrate being washed so as to impart insect repelling properties to it. The invented N-lower alkyl neoalkanamides have been found to be of long lasting effectiveness, with significant and measurable insect repellency being obtainable for as long as two weeks after application. They are stable during normal trees, relatively low in manufacturing cost, of high substantivities to substrates, economical to use, unobjectionable in odor to humans, and safe to humans and animals, and to the environment. In addition to insect repelling uses, the invented N-lower alkyl neoalkanamides are also useful components of perfumes. Various products, such as detergent compositions, shampoos, waxes and polishes, pet care items, insect repellents and insecticides, may be perfumed with the invented perfumes, which results in such products and compositions being made insect repellent so that surfaces to which they have been applied also become insect repellent, as well as perfumed.
