    Optigel is the best product out there. All of the nonsense with spraying the worker ants it a joke. You need to have the poison taken back to the colony to kill the queen. It only takes a few tiny dots to do the trick. Buy on Amazon.

    As crazy as it sounds, Jiffy Cornbread Muffin Mix has worked for me many times. Sprinkle it around where you see the ants. Within a few days you'll not see any more ants.

    My chickens are great for taking care of bugs in the yard, including ants. If you have the ability to keep a couple of chickens, you can get eggs (bonus!) and keep your yard free of pests.

    They keep ticks and fleas under control also.

    I use Sevin granules, sprinkle over the mound and spritz with water. They are dead within an hour.

    I have a friend who swears you can take a scoop from a mound and dump on another and they will kill each other but I've never tried it.

    Hello. I highly recommend the commercial products made by Terro. If you look over at the reviews and QA on Amazon and see how highly rated the traps are.


    I have been using them both indoors and outdoors - and been very successful in my overall situation. Additionally- I sometimes do an exterior Home defense foundation perimeter type product as well for spiders. Hope this helps.

    How to Control Ants Outdoors


    The big difference in controlling outdoor ants is that you can often see the nest and deal with it directly. Try some of these methods to get rid of ants outdoors.


    • Boiling water. Rake open the nest and pour in boiling water (add liquid soap for extra killing power). Boiling water does kill vegetation, so be careful using this method on lawns.
    • Vinegar. Mix equal parts vinegar and water. Add a few drops of liquid soap to increase killing power. Rake open the ant nest and pour in the mixture. Vinegar can kill vegetation, so use care when applying to lawns.
    • Water. Soak the nest for 15 to 30 minutes with water from a hose, saturating soil. Ants can survive underwater for about 24 hours, so you may need to repeat the treatment approximately 22 to 23 hours later to ensure ants truly drown.
    • Boric acid. Make your own liquid ant bait by blending 3 tablespoons sugar or peanut butter with 2 tablespoons boric acid crystals and 2 cups of water. Boil for 6 minutes to dissolve acid crystals. Cool and store in a labeled jar. Create a bait container using a yogurt cup or other container. Punch holes in it so ants can crawl in and out. Put 2 to 3 tablespoons of the solution into the bait container and cover with a lid or foil. Place the container near the ant nest.
    • Chemical ant killers. Open the top of the ant mound and apply an ant-killer pesticide (granules, dust/powder or liquid form), following label instructions. Some treatments work like bait and kill ants slowly, as they carry it back into the nest. Other chemicals kill ants on contact, which means you may not get the queen. In this case, the nest may eventually disappear, but a smaller nest may develop nearby. Treat this second nest and monitor the area for further ant activity.


  • You can boil water then rake open the nest and pour the water which you have boiled. You can also add liquid soap for more effective results. Or you can use vinegar and add it to equal parts of water. Soak the nest for a couple of minutes 15-30.
