Just to share on my workout.

1. Get a few termite bait. Place it at place where the termite is munching or thier route. Takes like 2 - 3 weeks and all termites will dissapear.
2. Get a 2 litre termite chemical. This needed to be done in 2 phase. Brew a 10 liter chemical and pour around your house coumpound (outdoor) during rainy season. Most probable after 3 -4 days of raining. Dampen soil will be a good medium to dilute the chemical and penetrate to the soil as soil is wet. Few days after the rainy season, one more round on the same quantity.

You'll enjoy a one - two years of peaceful life. This is not a permenant solution as this needed to re-do in every 3 or 6 months.

Saves some money too!
