My eyesight is not good enough to be sure the yellow aphids on my milkweed are those pictured but I must assume they area. It\'s my first year with milkweed too,. Near as I can tell I also have milkweed bugs and assassin bugs and assassin nymphs on them as well. I\'m thinking, since they are all at the flowers I\'ll make a jug with a little dawn and dunk the flowers. I have two monarchs wanting to be fed. I live in Fairhope, Alabama

I found them on a milkweed plant in my Garden. I trimmed off the branches they were on, I haven’t seen them on that plant since. But I did find some on a Hoya in my screened pool cage. I’ll try a few of the above remedies. I live in St. Petersburg, FL. It wasn’t on the list.

You can spray a rubbing alcohol and water solution on this and other aphids in order to kill them without leaving lasting pesticides that effect other insects. I use 1 part alcohol to 3 parts water and a splash of dawn dish soap. They are all black and dead the next day.

This is my first milkweed plant so I don\'t know what the long-term result will be. I had a good clumping of these aphids and decided to try cinnamon (cheap, giant bottle from a price-club store). Sprinkled liberally wherever the aphids were and now they\'re gone. That was weeks ago. Not sure if the powder simply suffocated them or what, but it seems to have worked!

More of a question. What if after you have blasted them off with the hose, you surround the plants with cheesecloth for a time so they will go somewhere else. then you could uncover for the Monarchs?

Great comment by Magpye!
These aphids have decimated our milkweed plants this year, and along with the milkweeds, the Monarchs are suffering, for sure. Due to heavy and prolonged moisture in the spring, the aphid populations have exploded. We blast with water, squish and squash these tiny guys daily, hoping to save some of our Monarch food. Hoping for fewer aphids next year!

The oleander aphid (Aphis nerii) is a distinct bright yellow aphid with black legs, antennae, cauda (tail-like appendage), and cornicles (tubes that extend from the abdomen). It is thought to originate in the Mediterranean and probably spread as oleanders were introduced around the world. The aphid is now found in tropical and temperate zones worldwide.

When the oleander aphid finds its preferred hosts, plants in the Asclepiadaceae and Apocynaceae, the population explodes. All of the aphids are females; they reproduce by parthenogenesis (clones of the mother) and they bear live young (nymphs). If conditions become too crowded on a plant or the plant declines in health, some of the aphids develop wings and will colonize new plants.
