After a mound is abandoned, the 



rain soon levels it to the ground. 



Control 



ChJordane, dieldrin. and aldrin 

 are the best insecticides to use for 

 controlling imported fire ants. Thej 

 rnav In- used to treat the mound- or 

 areas where the ants arc foraging. 



Emulsinable concentrates and wet- 

 table powders are available on the 

 market to use in preparing sprays. 

 Dusts containing these insecticides 

 are also available. 



Wherever possible, plan your con- 

 trol campaign during the cool months 

 of early spring. It is then that most 

 of the ants are underground and the 

 earth is moist enough to make the 

 treatment more effective. 



MOUND TREATMENT 



In small, lightly infested areas, 

 you can kill the ants by treating 

 individual mounds. A 0.25-percent 

 spray is highly effective for this pur- 

 pose. \ou can prepare such a spray. 

 using either chlordane. dieldrin. or 

 aldrin. as follow-: 



Tablespoon- Quart- t<> 



Emulsifiable fuls to 3 gal- 100 gallons 

 Concentrate Ions water water 



45% chlordane . 4 2

dieldrin. 12 6 



Ounces to Pound- to 

 Wettable 3 gall.nis 100 gallons 



Powder water water 



4<i c 7 chlordane. 2.5 5 



25% aldrin 4 8 



25 % dieldrin . . 4 8 



If you use a lower or higher con- 

 centration of insecticide, use pro- 

 portionately more or less of it. 



If you are treating a few mounds, 

 apply the spray with a L 2 -quart 

 sprinkler or water bucket. Where 

 there are several mounds, an orchard 

 sprayer with hose and nozzle attach- 

 ment makes the job a lot easier. It 

 holds more liquid and can be moved 

 quickl\ from mound to mound. 



Before applying tin- spray, break 

 the hard surface of the mound to per- 

 mit better penetration. Then pour 

 or spray the liquid into the spongelike 

 cavities. \pply about 3 gallons of 

 -pray to an average-size mound and 

 an area 3 feet around it. Make sure 

 the mound is well saturated. 



( Occasionally a portion of the colon} 

 may survive. Repeat mound treat- 

 ment in about 2 week-. Usual]} 1 

 gallon per mound i- adequate to con- 

 trol these surviving colonies. 



l)u-ts can al-o be used to control 

 imported fire ants in their mound-. 

 L se 5-percent chlordane. 2%-percent 

 aldrin. or 1 --percent dieldrin. Apply 

 1 to 2 cupful-, depending on the -ize 

 of the mound. \^ ork dust thoroughly 

 into the soil with a rake or other 

 garden tool. 



\^ hen dusts are used, a second 

 treatment is usually necessary. I se 

 about 1 cupful of dust for each surviv- 

 ing colonv until all the ant- have been 

 killed. 



AREA TREATMENT 



Spraying the entire soil surface is 

 more practicable in heavily infested 

 areas. It kills ants in the mounds 

 and wherever else they may be. 



Spray evenly. L se a weed-boom 

 attachment in conjunction with a 

 power sprayer. Tractor sprayers and 

 orchard sprayers are also effective. 

 Compressed-air sprayers may be used 

 with good results for treating small 

 areas. 



Four pounds of chlordane or 2 

 pound- of dieldrin or aldrin per acre 

 control imported fire ants for two 

 growing seasons. *ppl N anx of them 

 at this rate to uncultivated land when 

 crops are not grown for use a- food or 

 li\ estock Iced. 



For cultivated land, applj no more 

 than one treatment annualh alter 

 crops have been har\ c-tcd. preferably 

 in the fall or spring. It i- desirable 

 to follow the treatment b\ disking .
