I brought home a string of dolphins a few weeks ago and I saw today a bunch of (what I thought were) aphids. I contacted the seller and he insisted he does not have any on his plants and that aphids aren’t common on string of dolphins. I wish I took a picture of the little pests before spraying and washing them off, but I didn't. I sprayed it down with a neem oil and Castile soap solution, but want to make sure that this will resolve the problem. One little bugger came out as the solution was drying, but its MUCH more mature and full grown than what I was seeing. Hope the picture is helpful...thanks in advance for the help!
