If you see yellow/black it’s spider mites for sure.
With that many + eggs on a leaf it looks like they are dug in pretty good.
I get drastic with them, they don’t respond well to kindness.
I take the plant outside and use the hose to spray (the underside) the leaves. 99% of them are on the underside so I turn the plant sideways and spray it fairly aggressively and let it drip dry. I feel like a large majority of them are displaced by this. I like ladybugs to do the cleanup but if there is no time, I generally stick to garlic/soap based spray unless I ABSOLUTELY have to use neem. Trick is doing it a few times a week until they are gone, but it flower it’s becomes tougher every day. Still, the plant is ruined if you don’t act fast, so definitely do something.
