Borers have been killed in from twenty hours to three days; after they are found to be dead, the soil should be removed from around the trees so that any remaining fumes of bisulphide can be dis- sipated. The method in most general use is known as the "worming process.'' This consists essentially in carefully cutting out and killing the individual bor- ers.
