Application November 27, 1943, Serial No. 511,973 1 2 Claims. (01. 21-63) My invention relates to a device for exter mination of termites. There are many different species of termites but this invention is concerned with dealing with those termites only which may occasion,serious damage to woodwork of build ings or to stored articles, including furniture, books, or other articles of plant origin. The com mon type of destructive house termite of North America includes ground-nesting forms that cannot live without moisture, which they get from the earth. These termites occur practically throughout the United States. The normal habitat of these termites is in connection with dead wood, old stumps, etc, on which they feed, and in such locations they may 16 establish large colonies containing queens, wing 2 Everyyear it costs property owners consider able sums to replace or repair property which the worker termites have ruined to provide food for their colony. ' ' l The way to stop the damage caused by ter mites and to keepthem from causing damage is to prevent them from getting into the wood of buildings as by treating the wood in accordance _‘ with the present invention. It is universally " agreed that where wood is used, it should be treated with chemical preservatives to render the wood more resistant to attack by termites. It is, therefore, necessary to'impregnate the Wood with some chemical preservative of which there are many on the market, but such impreg— nation must be thorough. It is now the aim of this invention to provide a device for the pur less workers, and soldiers. In spring and fall, males and females, white winged but with black pose of very completely impregnating the lumber ' or brown bodies, swarm from the outdoor col and woodwork in buildings or other structure, onies, or from buildings to which their work has 20 with a chemical wood preservative. extended, to seek favorable points outdoors for Such a. device is illustrated in the accompany the establishment of new colonies.
