Seedlings are only about 1 set true leaves. I have never seen Spider mite but looking at the pictures on line, i think that is what I have. On the white foam cup surface, with my eye sight, I could only see the red little spider like structure walking fast, not jumping. I squashed it with my finger, it left a line of red pigment.

Some of the leaves are turning mottled white. Since the seedlings are so small, I am afraid they may kill them quickly.

What can I spray that will not kill the seedlings too? I already sprayed the dish liquid + oil in the evening. I am wondering if the sunshine tomorrow will interact with the oil & soap and cause damage to the leaves. Should I try spraying the seedlings with plain water tomorrow morning? Should I put trays in shade for a day or two?

Thanks for the help.

The oil might kill the mites, but yes. You should rinse off the plants a few hours after applying soap, before letting them back in sunlight. Neem oil should take care of them. Best way to apply insecticidal soap is at dusk, rinse in morning.
