After you've spent all the time and effort to finally have a lawn you could walk barefoot through, you may be horrified to find that you aren't the only one enjoying it as thousands of tiny fire ants barrel through the grass. This is a good time to put your shoes back on. Fire ants are known to be aggressive, and their sting can be felt for several days afterward. Getting rid of these pests is a process, but with the right materials you can quickly send them packing.
Place a piece of fruit or food onto a pile of dirt. If you don't care to have a mound of dirt just lying around you can put it into a large empty flower pot.
Wait until you see many ants swarming the bait and dump a bucket of soapy water onto them.
Stir the water around in the soil to kill many ants at once. Be sure not to do this near your home, set the planter or dirt pile at the far edge of your property. Repeat this as often as you would like to kill of large number of fire ants.
