NEEDS OF ENTOMOLOGICAL SANITATION IN AMERICA 41 



trap platform for the storage of manure and should have the manure 

 removed at least every 10 days. 



5. Garbage should be removed daily from all places where it accu- 

 mulates in large quantities, and two or three times a week from private 

 residences. All garbage awaiting removal should be kept in closed 

 cans. Garbage must not be dumped within the city limits unless it is 

 dumped on incinerators where fires will soon consume it. These require- 

 ments are necessary to keep down fly breeding. 



6. Tin cans, bottles, and receptacles which will hold water, must 

 not be allowed to accumulate in back yards, alleys or vacant lots, nor 

 may the}^ be dumped within the city limits or near residential sections 

 in the suburbs, because they furnish excellent breeding quarters for 

 mosquitoes. 



7. The city should be connected for sewers as far into the suburbs 

 as practicable, and all suburban properties not so connected should be 

 required to install fly-jDroof cesspools, or septic tanks, or to arrange by 

 neighborhoods for independent sewage with a common septic tank; or in 

 the absence of water and necessary plumbing, to install sanitary privies, 

 and be required to have all excreta removed once a week to an incinerator 

 or other type of refuse disposal plant. Open vault privies should not be 

 permitted in the city. Indiscriminate defecation on streets, alleys, vacant 

 lots, etc., should be strictly forbidden and punishable by law. 



8. Packing houses, candy factories, syrup factories, and all other 

 manufacturing institutions producing food products should be required 

 to screen windows and entrances, and to use fly traps in such a way as 

 to minimize to the utmost the access of flies and other insects to the food 

 products. Especial attention should be given to the prevention of insect 

 breeding on such premises. 



INDUSTRIAL SANITATION 



Many industries have important entomological sanitary problems in 

 the preservation of their products from insect contamination and in the 

 eff'orts to conform to sanitary regulations. There are many times when 

 they would be able to use the services of a consulting sanitary entomologist 

 to advantage. 



The keynote of industry today is the prevention or utilization of 

 waste. Insect depredations on food products cause waste because the 

 public does not want polluted food, and because sanitary inspectors arc 

 becoming more and more alive to the menace to health from insect pol- 

 luted foods. 



It is not generally understood that the presence of weevils and worms 

 in cereal foods may do more than destroy the food. The evidence is
