Abstract
A cellulose-containing member is provided with a plurality of holes transversely extending therethrough. An emitting element and a receiving element are located at opposite ends, respectively, of each of the holes. The presence or absence of termites is detected by the obstruction of an output wave from the emitting element caused by termites invading the holes, whereupon a detection signal is generated to cause alarm lamps and so on to light up for alarm display. Simultaneously, in order to estimate the number of invading termites, the number of occurences of an obstruction by the termites of the output waves from the emitting elements is counted.
