Yes, it smelled "oily". I sprayed Monday( I think) it was rain-free for about 10 hrs. Then I JUST resprayed some of the areas again! I guess we'll find out ! Maybe I'm expecting too fast a return on my money! I did use a "sticker' with it( not dish soap, but a regular "sticker/spraeder"). I hope it works, even if it's slow, it's better than getting on my knees to grub it out( I'd NEVER get Rita to do it! She does only broadleaf weeds, the grass is all mine!)....Arlyn
