Hi,
Im not 100% positive, but they seem to be some type of aphid, there are so damn many types to remember.
If I were uou begote I try any type of harsh insecticide or something I’d dust the plants with food grade
diatomaceous earth. …some companies product comes with a little duster apparatus, if not you can get them off Amazon for like $3/4. It’s the ground up remains of some long dead crustacean from prehistoric times, and is high on silicon, so it’s good fit the plants too.
Anyways, you put some in one of these duster bottles and blow it onto the plants making sure to cover both sides of leaves and stems as well. I grow in soil and always put about a 1/4” layer on top of my soil if in pit or in a 3’ diameter circle around plant if an in-ground outdoor. This stuff is like razor blades to the aphids, and many other small insects, and cut them up and kill them when they walk over it.
…a couple things to more about
diatomaceous earth is that it only works when dry, when it’s wet it won’t kill them. Also, it only kills living insects, not their eggs, so you need to keep reapplying it, as needed when it wears off for at least a week to ten days after infestation first seems gone; that way it’ll kill any as they hatch from their eggs before they get a chance to reproduce, which will end infestation for good. ….it works well, you should try it. I used this summer on several different species of aphids on my poppies, tomato plants, and my one bonsai and it killed them all.
Another route you could go is with insecticidal soap, which you coat the plant with and it basically won’t let them breath and they die. …and, like
diatomaceous earth, it’s non toxic
If those both fail you can use
neem oil or pyrethrum.
Those 4 things right there have gotten me through almost 30 years worth of insect infestations, and have never failed me. Normally, I don’t use anything more than
diatomaceous earth though. …I use regularly as a preventative as well, and the silicon is great for the plants as it helps build strength in its cellular walls. I regularly use it as an amendment in my potting soil recipe.
……but over all the years I’ve grown the best preventative treatment for aphids or any other type of insects I’ve ever found for indoor growing is grow room cleanliness.
A clean room=healthy plants!
……that includes everything you bring into the grow tent/room, including you.
That’s why you should always change clothes and shoes and don’t forget to wash your hands before you enter your grow. (and I’ve read where it’s even advised to wear rubber gloves, but personally I don’t unless I’m working with fertilizer(s).
Hope it helps brother,
Jory
