Many contact insecticides which include acephate (Orthene), carbaryl (Sevin), fipronil (Over ‘N Out), pyrethrins, pyrethroids (bifethrin, cyfluthrin, cypermethrin, deltamethrin, lambda-cyhalothin, permethrin, es-fenvalerate, tefluthrin or tralomethrin) & liquid fipronil or spinosad. are designed for the homeowner. They are widely available in retail stores, garden centers & farm/ranch supply stores (Wal-Mart, Lowe’s, Home Depot, CoOp, Tractor Supply, etc.). They are sold in small containers with enough material to cover a home yard. These ingredients vary in how fast they kill ants & how long they persist in the environment. Natural pyrethrins or synthetic pyrethroid ingredients kill ants in minutes. Acephate & carbaryl take a day or so, while granular fipronil may take 4-6 weeks to eliminate colonies. Hot water, pyrethrins, d-limonene treatments have little or no lasting effect. Carbaryl & acephate break down in a matter of days to weeks, while pyrethroids can persist for weeks to months & fipronil can persist for months to a year. Each product has its pros & cons... but all of them work.
If you have an Texas Applicator's License, there are products that you can use that are not available to the public... let me know if you have one.
Good knowledge of chemicals. But we can use it by our own or shall we contact a pest expert to use them for killing insects like fire ants? I am asking this because my aunt had a pest problem few days ago and she contacted pest controllers from pest control Elk Grove and they helped her out in getting rid of pests. She told that they just don't spray at home, but they work on the areas from where insects are entering your home.
There are a lot of solution to get rid of this monsters. You can add some pestice that include permethrin. Another effective way is to prefer feeds containing hydramethylnon, fipronil, boric acid or avermectin B. Also you can use coffee grounds, baking powder, pepper, cinamon etc. If you need extra info check this website :
