I've used straight out of the bottle bleach. It worked but in a smaller application. Just a vine abour 10ins or so. When I see one starting I douse it with bleach then wash my hands and anytools used with Fels-Naptha bar soap. I really don't care if this soap in environmentally safe as it is petroleum based -it works and that's all I want it to do. I don't use any other chemicals
