Control 



Chlordane, dieldrin, heptachlor, 



and aldrin are the best insecticides to 



use for controlling imported fire ants. 

 They may be used to treat the 

 mounds or areas where the ant- art- 

 foraging. 



Emulsifiable concentrates and wet- 

 table powders are available on the 

 market to use in preparing sprays. 

 Du^ts containing these insecticides 

 are also available. 



Wherever possible, plan your con- 

 trol campaign during the cool fall and 

 spring month*. It is then that the 

 ants are most active and the earth is 

 moist enough to make the treatment 

 more effective. 



MOUND TREATMENT 



In small, lighth infested areas. 

 vou can kill the ants by treating 

 individual mounds. A 0.25-percent 

 spray is highly effective for this pur- 

 pose. You can prepare such a spray, 

 using either chlordane. dieldrin. 

 heptachlor. or aldrin. as follows:

If vou use a lower or higher con- 

 centration of insecticide, use pro- 

 portionately more or less of it. 



If you are treating a feu mounds. 

 apply the spray with a 12-quarl 

 sprinkler or water bucket. \\ here 

 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 the spray, break 

 the hard surface of the mound to per- 

 mit better penetration. Then pour 

 or spra) the liquid into the Bpongelike 

 cavities. M>p'> about 3 gallons of 

 spray to an a\ era<:e~ ize mound and 

 an area 3 feet around it. Hake w/r<- 

 the mound is well saturated. 



( Occasionally a portion of the colony 

 may survive. Repeat mound treat- 

 ment in about - weeks. I sually 1 

 gallon per mound i- adequate to con- 

 trol these surviving colonies. 



Dusts can also be u-ed to control 

 imported fire ants in their mounds. 

 L se 5-percent chlordane. 2)£-percent 

 heptachlor. ^.-percent aldrin. or !'■-_- 

 percent dieldrin. Apply 1 to 2 cup- 

 ful-, depending on the size of the 

 mound. ^ ork dust thoroughly into 

 the soil with a rake or other garden 

 tool. 



When dusts are used, a second 

 treatment i- usually necessary. Use 

 about 1 cupful of dust for each surviv- 

 ing colony until all the ant- have been 

 killed. 



AREA TREATMENT 



Spraving the entire soil surface is 

 more practicable in heavilv infested 

 areas. It kills ants in the mounds 

 and wherever else they may be. 



Spray evenly, L se a w eed-boom 

 attachment in conjunction with a 

 power spraver. Tractor sprayers and 

 orchard -prayers are also effective. 

 Compressed-air -prayer- may be used 

 with good results for treating -mall 

 areas. 



Four pound- of chlordane or 2 

 pounds of dieldrin. aldrin. or hepta- 

 chlor per acre control imported lire

For cultivated land, apprj no more 

 than one treatment annually after 

 crop- have been harvested, preferably 

 in the fall or spring. It i- desirable 

 to follow the treatment h\ disking.
