It depends on how well you sprayed them and how good the product works. They will lay eggs on the underside of the leaves and one single spider mite can produce hundreds more.
What you don't want to hear:
Once you have an infestation, you're better off cleaning out your grow room, bleaching everything down and use a fogger if you can.
Bleach the walls, floor, pots, pans, fans, everything! Dump your medium and start fresh.
What you do want to hear:
If your spider mite issue was relatively small and you are sure you got rid of ALL the mites and the mites didn't already do enough damage,
you may have good success cutting and cloning. Use a 30x microscope, which every grower should have, and spend some quality time checking
your plants. You won't need to treat the clones if you got rid of the mites and eggs.
I'm assuming you are fairly new since you only have 2 posts. I may be wrong. But, when you clone, it usually takes about a week for them to bounce back
and grow good roots. I'd be careful to treat them with any chemicals during this process.
I would take some cuttings, one at a time, and thoroughly check them for eggs/mites. Be very strict when you check them or you'll just be back to square one.
Hope this helps.
