How to get rid of spider mites
Look at the surface of the leaves.
If your plant is indeed infested with spider mites, the leaves may have yellow blotches on them. When light falls on the leaves, you may see a silvered look or even streaks of bronze or silver.

Choices:
(a). While mites usually attack the underside of leaves, they can sometimes get greedy and also eat the upper side of leaves and flowers. Eventually, the mites will suck holes right through the leaves-providing the most obvious evidence of infestation.
(b). If either of these colors suggest spiders, seek immediate help. You can also check where the leaves were sprayed with the insecticidal soap or simply observe them carefully to ensure nothing or nearly anything is stuck to them.
(c). Leave the leaves undisturbed for a few days to allow the bugs to multiply. If you notice that spider mites are present at all during this time, you can avoid them further by simply removing the infected plants from your garden and keeping them out of your yard.
(d). Once the spider mites are completely gone, you can look at the underside of the leaves. If they have a tiny, pinpoint looking spot near the surface, there is probably a mite infestation.. The answer should be
(a).
