take a paper plate and cut a slice in it to the middle. make a small circle for the main stem. Place the plate around your plant, this will cover the dirt and prevent the ones on the leaf to fall into the dirt and the new ones from coming up to your plant. Now you can spray your thripe mix on the leaf without having more come up.

I believe you can use a neemin's oil at this point, but not 100% positive.
whatsthatsmell Reviewed by whatsthatsmell on . Making own pest control spray So my cousin looked at my plants and said i have some thripes. He said what i need to do is to let the soil dry out real well, and then spray a solution of water and liquid soap on it. Also said i might have to repeat the process a few times. So i was just wondering, what ratio to mix the liquid soap with the water. And so i spray that on over the plant, and a little on top of the soil. Will the plants have residue on them, do i need to wash them off? Just a few questions hope someone can Rating: 5
