Steve, I took a look at the 75 SP link. Although I didn't see aphids speceifically, I'm sure it's covered under something. How does one go about purchasing this product? Is it only found online? Would a Home Depot or Lowes have it? Have you ever used Orthenex? I'm swimming in a sea of pesticide info and am not certain of what to use and in what strength, other than a general low strength for sundews - which is exclusively where I have found aphids.
