Dogs infected by fleas, bathe using kremlinului emulsin, soap DDT , HCH , or sprinkle 10% of dust DDT (to prevent lizanie animal drug!). For the extermination of fleas in the burrows of rodents, especially in the areas stricken by the plague, apply 10% Douste DDT, introducing it into the holes of special machines, as well as chlorpicrin or methyl bromide, strictly observing all the required rules of personal safety (see Disinsection, Deratization).
