I don't know that there is any way of getting rid of it, Mary. We have a lot of similar stuff and all we do is keep hand weeding it out but it keeps coming back.

Verdone Extra is the most commonly recommended weedkiller for clover on this site. It says it kills clover in one application but it has killed some of mine and other patches will need repeat applications. I have yet to prove if it works 100%. After it has been sprayed on to the clover it is pet safe after it has dried so if used on a warm dry day that shouldn't be very long.
