A few days before the fair starts, spray livestock sheds, outdoor privies, empty food 

 tents , and other buildings that may harbor flies with dimethoate (Cygon) , fenthion (Bay- 

 tex) or Ravap. A farm crop sprayer, equipped with a lead of hose and a spray gun, can 

 be used for this purpose. Apply the spray to the ceilings and walls to the point of 

 runoff. Most rotary pumps on these sprayers can be adjusted to operate at 250 to 300 

 pounds of pressure. If the water pressure is good (30 p.s.i. or more), a spray gun 

 that fits on the end of a garden hose will do a good job of applying the insecticide. 



Sprays should also be applied to refuse containers , garbage cans , and the like before 

 and during the fair. A couple of men with compressed-air tank sprayers can do this job. 



Flies are attracted from great distances to the odors of animal waste and foods. These 

 flies are not killed until they land on a treated surface. For a quick knockdown of 

 these incoming flies in animal shelters and other places, use a small electric fogger 

 with oil- or water-base pyrethrum, dichlorvos (DDVP) , or naled (Dibrom) . These fogs 

 can be applied best in the early morning when no people are around. Animals need 

 not be removed, although horses may be frightened by the fog. 



Urge that food stands keep some pyrethrum or dichlorvos in a pressurized spray can for 

 the quick kill of adult flies. These sprays should be used at night after the stands 

 close. The local health department should insure that all stands maintain the re- 

 quired standards of cleanliness. 



HOMEOWNER PROBLEMS 



Fleas ordinarily annoy only dogs and cats. But left uncontrolled, fleas can become 

 a serious problem in a home or a yard by late summer. They attack people on the legs, 

 often leaving a series of two or three punctures in a row. Persons who take their 

 cat or dog with them on vacation or put them in a boarding kennel may find a multi- 

 tude of hungry fleas waiting when they return home. These adult fleas have developed 

 from the eggs and larvae that were scattered about the house. 



In the worm (larva) stage, these fleas live in the bedding of dogs and cats, in rugs 

 and upholstered furniture, and even in the dirt in flower and shrubbery beds. The 

 worm stage is usually not noticed and is harmless , but adult fleas suck the blood of 

 warm-blooded animals. 



Your dog or cat is a walking bait station for fleas. As long as the pet is around, 

 people are seldom attacked. During the warm months (May to October) , use a dust on 

 your pet of either 4-percent malathion or 5-percent carbaryl (Sevin) . Apply the 

 treatment every month or so, especially if your pet is in contact with neighbors' 

 pets or if the pet animal roams a lot. Treatments should also be made once or twice 

 during the colder months (November to April) for added protection. 



For emergency use, the plastic resin flea collars containing dichlorvos (Vapona, DDVP) 

 are generally effective in preventing problems with fleas. Some dogs and cats are 

 allergic to these collars; if so, skin ailments can result. Be alert for allergic 

 reactions if you use flea collars on your pet. Also remember that these collars are 

 effective for several weeks , but not the entire year. 



In case of severe problems, treat the pet as suggested above; but also spray a mist 

 lightly over rugs, upholstered furniture, beds, and other areas where fleas are nu- 

 merous. Use 0.1-percent pyrethrum or 1.0-percent dichlorvos (DDVP), applied from a 

 pressurized spray can. This will give a quick knockdown and kill of the fleas hit 

 with the mist, but it is not lasting. Repeated treatments may be needed.
