I have a bad spider mite problem in a huge grow I have. 10 plants. Pretty much about 50 percent of the tops have webs on them. Yes I know but I'm trying to not have this grow destroyed. Lol. I bought 1500 ladybugs. I'm just wondering how to invite them on the plants? One at a time on the tops where there's webs or just dump them in the soil under the plants? It's tough cause they all wanna crawl out together and I can't handle that. Lol. I have saucers on my floor with water for them. Any help will work thanks
