2,2'-Bridged[1,1'-biphenyl]-3-ylmethyl carboxylates and insecticidal compositions containing these esters are useful for the control of a broad range of insects and acarids. Certain 3-(2,2-dihaloethenyl)-2,2-dimethylcyclopropyl and 3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropyl esters are particularly effective against acarids.
