Bayer brand miticide is effective but its not commonly available locally. Google Blue Sky agricultural supplies at Phonenix Road, they may have it or be able to recommend an alternative.

Thanks for all advices given. I am trying to use tap water to flush off the mites from the plants last night. Hope it could work so that i dont need to use any chemical.

They don't like humidity. U can Spray the leaves it a few times day and/or move it to a more humid spot.

Jyilailong,
I believe you are refering to false spider mites (Tenuipalus Pacificus)that are commonly found behind
the orchid leaves, especially for Phalaenopsis. False red spider mites are very destructive as they suck the cell content
of the plant, leaving behid pits of dead tissues.

You can buy White Oil from nursary (about $10 per bottle (750ml)and spray it on the leaves, both front and back.

Alternatively, you can make White Oil yourself:
1) Mix 1 vol part of dishwashing liquid detergent and 4 vol parts of neem oil in a 500-mi plastic bottle.
2) Shake the mixture vigorously for 1 minute , the mixture will turn milky.
This is your concentrated white oil
3) to use it, dilute 1 tablespoon (15ml) concentrated white oil in 1 litre of water, shake well and spray on front and back of the leave.
