What you describe sounds suspiciously like creeping charlie. (Glechoma hederacea) Many gardeners have had good luck eradicating the plant by mixing 10 ounces 20-Mule Team Borax in 2-1/2 gallons of water and applying the mixture to the weeds. The boron doesn't affect turfgrass, but overwhelms the roots of creeping Charlie. Cool weather reduces its effectiveness so apply when the weather is warm. The University of Minnesota and Iowa State University have tested this recipe and report good results.

Chemical control for creeping Charlie in your lawn is a postemergence broadleaf weed killer containing dicamba often found mixed with other weed killers, 2,4-D and mecoprop or MCPP in combination products (Trimec, Three Way Lawn Weed Killer, etc.) Products containing triclopyr or 2,4-DP may also provide decent control. A second application later in the season according to label direction can provide additional control.

Best wishes with your lawn.
