Our lawns are being overtaken by clover & dandelions. The dandelions are just a little annoying, but the clover is covered (and I do mean covered!) by bees. One of our boys was stung this last week and it's only a matter of time before more (and we have bee sting allergies in the family), so we're looking for something to kill the clover and the dandelions that are attracting the bees. Have any of you used a weed & feed product on lawn that is used by your dogs? If so, how long do you have to keep them off of that section of lawn until it's safe for them again? I hate to use chemicals at all (and we're on a well, so that's another factor) but the bees have got to go! Suggestions?
