Is there anything I can do to detroy ant hills and kill all of the ants?

Try using borax, apparently it is supposed to work for ants. Mix a bit with a tsp. of sugar. The ants carry it back into the nest. Thus killing the Queen too.

Remember, in order for the act to become a "greater sin" you must have clearly known it was wrong and did it to mock the Lord. Truthfully, at age 7 i don't think the above is possible, you were probably carrying-on with the other children and wanted to fit-in etc... Sometimes, insects can be a real problem and even as adult Christians we use bug spray or even a fly swatter. The idea is not to make the irritating insect suffer while enjoying what you are doing. God bless'

equal parts of borax and sugar(or honey) melt it over a flame to make a honey like solution. The ants love it they will take it back to the nest, also borax will not harm any other animals. just leave a few shallow plates of the solution around the nest, at first the ants will swarm to it then disappear.

There are many ant killers on the market go to the local homecenter and get some.

Baby powder works. I don't know how but it did for me (a friend told me to use it). Pour baby powder all over the mound until it is comepletely covered & then some (make it look like a mound of baby powder). You can get a bottle of baby powder @ the dollar store for $1.

Borax is the best solution, if you have pets &/or children around.

We use it on brick paver pool decks.

It is an ongoing problem in FL.

Hot water. Make sure that you won't kill the surrounding plants by spilling on them or getting their roots.

My grandfather always used turpentine!

borax- not only will it kill them, it will also torment them emotionally by killing their whole family

Feed them rice, it makes them explode.
