Among the liquid killing agents are ethyl acetate (CH3Co2.C2H5), ether (diethyl ether, C2H5.o.C2H5), chloroform (CHCI3), and ammonia water(NH4OH solution). Ethyl acetate is most widely used. All of these chemicals are extremely volatile and flammable and should never be used near fire. Children should only use them under adult supervision.
Ethyl acetate is regarded by many as the most satisfactory liquid killing agent. Its fumes are less toxic to humans than those of other substances. Although it usually stuns insects quickly, it kills them slowly.
