Abstract
Abstract Insects are combated selectively in the presence of other forms of animal life by applying to the locus of the insects an effective amount of 2,3-dihydro-2,2-dimethyl-7-benzo[b]thienyl N-methylcarbamate, a compound with less mammalian toxicity than closely related carbamate insecticides.
