The Danger from Mosquitos.
State Commisisoner of health for Pennsylvania has issued a paper on the subject of how to get rid of the mosquito, which contains the following :
“No one can get malaria unless bitten by a malaria mosquito. Hence the necessity for its extermination. In water, especially stagnant water, where this mosquito breeds, it is almost invariably associated with mosquitos that are merely a nuisance, of which the commonest in our state is the house or rain-barrel mosquito. Mosquitos breed only in water, and only water that is free from their enemies—fishes and other predacious animals, such as aquatic insects, or in bodies of water that are fringed or covered with vegetation that protects them from their foes. Mosquitos can be permanently removed by Idling in or draining, or cleaning and stocking with their natural enemies, water areas in which mosquitos breed, and that the application of fuel oil or kerosene, which does not do away with, but only suspends the cause of the trouble, should be resorted to only until the lasting remedy can be used. Thorough screening of the house with netting of wire screens having 18 to 20 meshes to the inch will keep mosquitos from getting indoors. Should mosquitos get in through openings of doors and windows their numbers can lie reduced or even be done away with by the burning of jitnson weed (stramonitum) and saltpetre. The space to be rid of mosquitos must be tightly closed so that no fumes can escape for two hours. Then three parts of the powdered jimson weed mixed with one part of the saltpetre is spread in a layer one-half inch thick on a tin sufficiently large to hold all the mixture necessary. The powder is then lighted and the fumes will shortly penetrate the space, provided at least eight ounces of the mixture is used for 1.000 cubic feet of space Mos quitns may be repelled by the burning of Chinese punk and by the less desirable application nf equal parts of olive oil and of eitronella to the faee, hands and ankles every half hour or so Carrying naphthaline or bar camphor in the pockets is also of use.
