98 THE AMKIi/CAX MlsKIM J()rj(.\AL especially in the fall after houses wliicli li;i\ c Imch dosed during the summer are reoix-ucd. LMr\al fleas liaxc iiiiiiit(iiii;)ted opportunity durinj^ the sutnnier to develop into a(hilts which sometimes make a house literally uninhaliit;il)le. Me;i> aic considered degenerate members of the Diptera, the order to which flies and mos(;uitoes belong, and they are wingless, winglessness often accompanying the parasitic state, perhaps through disuse of these organs. That the flea lacks wings may make the si)read of plague less rapid; the lack of flight powers, however, is counteracted by the fact that fleas are carried long distances by their hosts. In the East, practically the only flea that gains access to the house is the cat and dog flea (Ctcnoccplutlns canis), the human flea (PuJrx irriians) Ix'ing rare. Measures for ridding a house of fleas must i)lan to attack not only the adults but also the eggs and larva>. These are likely io be in the dust of the animal's bed and in cracks and crevices al^out the house and furnitiu'c. The remedy lies in making it ini))ossit)le for the eggs to develop and the lar\;e to li\c in these places, in pro\'iding for the cat and dog sleep- ing places that can be kept clean with all dust remo\-ed and burned. A liberal use of j)yrethrum ))owdei' should be made in all places where it is possible that flea eggs may have fallen. Kerosene or benzine are valuable if milder means do not suffice while in extreme cases fumigation with hydro- cyanic acid may be necessary. The rat flea (LannopHyUa chropis) is known as the "plague flea," but both the hunuin flea and the cat and dog flea also live on the rat so that any one of these may act as a carrier of the plague germ if they chance to travel from a plague-infected rat. It has developed through a ft'W deaths in ( aliforiiia dii'eetly traceable to handling ground squirrels that here too danger lies, that tin; plague bacilli have reached these rodents probably from rats which use the s(;uirrels' holes in fields. The discovery may mean the necessity of extermination of the squirrels in infected regions.
