Finding Abamectin Miticide for Dahlia Spider Mites - September 2026
Over the past few weeks, I've made mention of a challenging infestation of Spider Mites that have come to take over a good swath of the dahlias in the sideyard. Despite treating them multiple ways, they seemed to stick around and continue to attack the plants. I started by spraying everything with my normal miticide - Bifenthrin. That has (historically) done the trick. But, either the Spider Mites are immune to it, or I wasn't mixing it strong enough. Because, they not only survived, they seemed to grow. And take over more plants. I did all the non-synthentic things, too. Like...giving the plants a STRONG spray of water to knock the mites off. And, I went for two-plus weeks with a heavy-hand of Neem Oil concentrate. I sprayed the tops of the leaves. I sprayed the bottoms of the leaves. I sprayed the stems. I sprayed the soil. I sprayed the blooms. Nothing would stop these freaking Spider mite...
