LIVESTOCK INSECTS 



Pasture flies are increasing, particularly in the central and southern sections 

 of Illinois. Horn flies , stable flies , and face flies rob you of milk or beef 

 production. Don't let flies pick your pocket. Follow these suggestions. 



For control on dairy cattle, apply crotoxyphos (Ciodrin) as a 2-percent, water- 

 base spray at the rate of 1 to 2 ounces per animal two to four times per week. 

 A 1-percent dichlorvos (DDVP) or a 0.1-percent pyrethrum spray, applied at 1 to 

 2 ounces per animal each day, can also be used. Pay particular attention to 

 the animal's legs and undersides when spraying. Also, for dry stock and young 

 stock on pasture, as well as for lactating animals, use a 1-percent Ciodrin, 

 water-diluted spray. Apple 1 to 2 pints per animal, as often as once per week 

 if needed. Ciodrin is the most effective insecticide for face-fly control . 

 All of the above insecticides provide good control of horn flies and fair con- 

 trol of stable flies. 



To control pasture flies on beef cattle, apply a water-base spray of 0.5 percent 

 toxaphene, using 1 to 2 quarts per animal every three weeks. Toxaphene provides 

 excellent control of horn flies, fair control of stable flies, and poor control 

 of face flies. 



If face flies become a serious problem, use crotoxyphos (Ciodrin) as suggested 

 for young dairy cattle. A canvas or burlap head-oiler or back-oiler, saturated 

 with a solution 5-percent toxaphene in oil, will provide some relief against 

 face flies. Do not apply toxaphene to beef cattle within 28 days of slaughter. 



HOMEOWNER PROBLEMS 



Mosquitoes . To help reduce the number of mosquitoes in home yards, follow these 

 steps : (T) Eliminate standing water in such places as eave troughs, old tires, 

 tin cans, childrens' toys, storm sewers, etc. (2) Apply a water-base spray con- 

 taining 1-percent malathion (2 ounces of 50- to 57-percent liquid concentrate 

 per gallon of water) to shrubbery and tall grass. Repeat the treatment every 

 week or two if needed. (5) Keep the screens on doors and windows in good re- 

 pair. (4) Hang plastic resin strips (2 by 10 inches) containing 20 -percent 

 dichlorvos (DDVP) --one strip per 1,000 cubic feet of space, or about one per 

 room. These strips will kill mosquitoes and flies afor 4 to 6 weeks. Do not 

 use these strips in kitchens or other areas where food is handled. Do not use 

 them in any room where infants, the ill, or aged persons are confined. A 0.1- 

 percent pyrethrum space spray- -applied from a pressurized spray can- -can be 

 used for quick knockdown in place of the dichlorvos resin strips. Frequent 

 treatments will be needed during problem periods. (5) When entering mosquito- 

 infested areas, use a repellent. One of the most-effective mosquito repellents 

 is DEET (diethyltoluamide) . (6) For quick knockdown at cookouts, outdoor par- 

 ties, or picnics, use either 0.1-percent pyrethrum or 0.5-percent dichlorvos 

 (DDVP) solution as an oil- or water-base, space spray. Spray the mist lightly 

 beneath tables and chairs and into the air for a few feet around the area. Re- 

 peat the treatment as needed.
