Provide tlRht containers i7ith ti^'.ht covers such as gaivaaized cans for 

 wastes. Staiid them on a hard, easily cleaned surface, limpuy waste 

 containers and clean them every day. Bury or burn the wastes immediately -- 

 flies travel farther than you may think possible. 



Clean out and remove empty boxes, basUets, cartons, etc. Store them as 



far from the stand or mill as possible. A dump ouc back may be out of 



sight, but the flies it attracts and breeds will be out front in full 

 view. 



2. USE RESIDUAL INSECTICIDES ON SURFACES! 



Apply residual materials to all surfaces in and around the stand, sales- 

 room or mill on which flies commonly rest. AVOID contamination of edible 

 products and follow directions exactly to get the best results. 



lettable powders leave a visible deposit; emulsifiable concentrates diluted 

 with water do not; oil solutions are not diluted and leave no visible deposit. 



DDT is still effective against many flies, including the tiny fruit or 

 vinegar flies; mcthoxychlor is similar and preferred inside the stand or 

 mill. Diazinon may be used as directed on labels as a residual treat- 

 ment to wall and other fly-resting surfaces inside and outside the 

 stand or mill. Ovitside surfaces and dumps may be treated with chlordane, 

 Diazinon, or malathion, the latter two being effective against flies 

 immune to the other materials. Malathion is safe and effective, but has 

 a short residual life. Both Diazinon and malathion are more effective 

 if sugar is added to them as directed on labels. 



3. BAITS SUPPLEMENT other MEASURES! 



Dry baits containing malathion, Diazinon, and Dipteryx are available under 

 many brand names. Use them sparin^ily, but frequently, on all horizontal, dry 

 surfaces in or around the stand or mill v?here flies tend to gather. Liquid 

 or spray baits are described on Diazinon and malthion labels. They can be 

 very helpful where over-all residual spraying is not desirable. 



4. SPACE TREATMENTS ESSENTIAL TOOl 



Stands and mills that can be closed up completely or enough to prevent 

 cross ventilation may be ''space treated" with a finely atomized spray 

 or aerosol. All flies then in the building should be killed by the 

 treatment; there is no residual effect. 



Apply space treatments at closing time and at other times as operations 

 permit and the number of flies make it desirable. 



Pyrethrin or allethrin, each synergized by materials like piperonyl 

 butoxlde, sulfoxide or others, are the chief killing agents. Some pro- 

 ducts contain methoxychlor or other materials. Products containing DDT, 

 chlordane or similar materials should not be used unless edible foods 

 are covered.
