When checking on my seedlings this morning, I noticed a few that looked like the leaves had been eaten. Looking closer, I saw little red dots on the underside of leaves. I think these are red spider mites. The first pic is of a ground cherry, and the 2nd is an orange bell pepper. I'm sure there are mites on some of the other seedlings.
Since I don't want to spray these tiny seedlings with water, I guess I'll use some safer soap spray on them. Any other ideas - preferably organic?
PS: I didn't realize the pics were so fuzzy. Hope you can make them out.
Looks like spider mites- the little monsters just wait for a baby plant to jump on- You need to control them fast! Already there are a lot there. Is it possible to wrap the roots with plastic and dip the foliage in a mixture ? You could use some warm water with some liquid dish soap and try to drown them. Spraying would be hard to do on tiny sedlings.
They look too big for spider mites - I typically can't see spider mites on the plant and can only confirm by shaking the plant over a piece of white paper and then taking a magnifying glass to it. I think they look like aphids too.
I'm thinking they're aphids. Try spraying them with a solution of dish soap, rubbing alcohol, and water. I just give a good squeeze of the dish soap, a cap full of rubbing alcohol into a large spray bottle (28 oz).
Aphids really like the young new growth on a plant and those cant be spider mites. You would not be able to photograph spider mites. They are too small. Also, spider mites like it hot and dry. Usually only get them this time of year indoors where it is dry. Aphids will come off with plain water spray but a little soap wont hurt.
I think everyone's right - they're spider mites! I had some Safer soap so I mixed up some in a spray bottle and sprayed them away. I'm keeping a close eye on the seedlings sine I keep finding a few more. Thanks for all the help - and correct identification.
