You probably have every thing you need in your kitchen and/or laundry room. Take a gallon of vinegar mix in a cup of salt and a half cup of dish detergent. Mix it up and spray it on a nice day with no rain in the forecast. You will notice it to start dying in a couple of hours. In a day or two it will all be dead. That is what I do and it works great.

Is there some chemical made to stop this?
