FEWER FLIES MEAN MORE CUSTOMERS

Flies in and around your roadside stand or farm salesroom can 

 hurt your business. There are ways to reduce their numbers. Such 

 procedures should be a regular part of Good Management. 



Common house flies are attracted to moist, decaying organic 

 material such as fruit and vegetable refuse and manures. The tiny 

 fruit flies go for fermenting plant juices, while green and blue 

 "bottles" prefer meat, garbage and dog stools. All these flies 

 travel amazing distances, but a large population means they are 

 breeding nearbyl The first step in controlling them is obvious.

Apply residual sprays on surfaces where flies rest; do 

 not contami nate foods . Repeat as necessary. 



All around the outs i de , use dimethoate (Cygon*) or ronnel 

 (Korlan*) or Diazinon* emulsible concentrate, diluted with 

 water as directed on labels. 



Use ronnel on inside surfaces that can be treated without 

 danger of food contamination. 



Employ space treatments to kill flies inside at closing 

 time and when convenient or necessary at other times. 



Use aerosols containing either pyrethrins or DDVP (Vapona*) 

 Follow directions to avoid food contamination. 



(Note: 



If ventilation can be controlled or if it is not excessive, 

 the yellow resin strips from which DDVP (Vapona*) vapor is 

 volatilized at a constant rate may prove useful. Don't 

 expect results if directions are not followed as to ventila- 

 tion and number of strips per unit of space. 



Other suggestions to help control flies: air currents 

 created by fans; fly baits, used as directed; yellow Bug- 

 lite* bulbs; Geigy Snip Bands* hung as directed.
