I have dealt with those a bunch.. just never for my grow.. I always just throw them back outside. What I use in my garden is Neem oil. Works by making the bugs forget to eat fly and reproduce. I use this preventatively and spray each plant twice during the grow... I don't spray the upper leaves. If a major bug problem I use a tiny bit of Spinosad. It is a chemical we used to use at a garden center I worked at. It usually gets rid of anything quick. I do prefer to use Neem though because it is completely non toxic. Hope you get this sorted soon best of luck!!!
