40 SANITARY ENTOMOLOGY 



Sanitarj'^ inspectors need to exercise considerable vigilance in checking 

 up obedience to ordinances relating to removal of trash, garbage, manure, 

 excreta ; installation of sewage or sanitary privies ; proper sanitation 

 among construction gangs ; nuisances arising from stables, factories, 

 sewage and garba'ge disposal plants, packing houses, stock yards, etc. 

 Many manufacturing plants have waste products which are very attrac- 

 tive to insects. Insect conditions in restaurants, boarding houses and 

 hotels should be frequently checked up. 



Anti-fly and anti-mosquito propaganda should be conducted annually 

 in every city until the people are so well educated to the necessity thereof 

 that propaganda will no longer be necessary. 



The sanitary department of large cities should directly supervise 

 mosquito suppression within its bounds. 



ENTOMOLOGICAI. REQUIREMENTS OF MUNICIPAI. SANITATION 



The following points should be covered by ordinance in all large cities 

 desirous of obtaining satisfactory sanitation. Not enough attention 

 has been given by city health authorities to the insect side of their 

 sanitary problems. 



1. All foodstuffs, which are eaten raw, all raw meats, fish, birds, 

 cooked foods, bread, cheese, dried fruits, etc., must be kept under cover 

 of glass or screen or otherwise protected from insects, in all markets, 

 stores, street stands, hotels, restaurants and boarding houses. Flies must 

 not be allowed to congregate around food stalls. Cockroaches must be 

 eliminated from all hotels, restaurants and boarding houses. Foods 

 infested by insects should be subject to condemnation and destruction. 

 Insect contamination of food is dangerous. 



2. Hotels, public institutions, and lodging houses shall be required to 

 keep their premises free of bedbugs. Bedbugs carry disease. 



3. All school children shall be inspected at the beginning of each 

 new school year for head lice, and oftener if circumstances warrant. In 

 case the children are infested they should be isolated and sent to some 

 clinic whei'e they can be freed of the lice. All prisoners, patients in 

 hospitals, and applicants at municipal lodging houses should be in- 

 spected for head, body, and crab lice, and if infested should be bathed and 

 their clothing condemned or cleaned. Lice carry many diseases and every 

 opportunity should be taken which will enable the authorities to reduce 

 their incidence. 



4. All livery stables shall be required to remove all manure to the 

 country daily, unless specified places for dumping are set aside. All 

 private stables should be provided with a fly-proof box or a maggot-
