pls take note that termites can migrate from your neibour houses thru roof trusses. so it is best if you can spray chemicals on the roof truss every 3-5 years. (short term protection) The more concentrate the better, the shop sell from 20% to 45% w/w.  This is neccessary as most of the timber truss is not well chemicals treated. (cheated by saw mills)
pls dun spray the same chemicals on furniture, cupboard, cabinets and doors as it is very toxic to human.

drill and pump chemicals - dun believe this! it wont last long due to msia hot and wet wheather.

hmm fipronil can also be used to paint the wood not a problem (extremely efficient). and since its not easily washed away at all lacing the soil is extremely efficiend (unlike the normal drill jobs i take it). its non toxic to humans and pets so added plus - i found this stuff very convincing. we also painted the beams and doorframes with it and pumped underneath a visible termite colony at my neighbours place. two weeks later - no trace (note: pumped underneath not on them, so they must get in touch with it first). its more expensive but will last easily 5-10 years so that saves a lot of hassle afterwards

it's true that they have to drill & pump chemical every few years..   thats why i run a set of pipes before i laid my tiles

Termite treatment is actually a good LONG TERM investment and recommend you should do it, after all the cost compared to the house itself is very small indeed. I didnt do for my house in the beginning and regretted it last two months ago. Colony of termites decided to move into my place. Had to clear out 50% of the stuff and do spraying. Hard time, wish i'd spend that RM600 in the beginning. Total damage was about RM5k...

Last words...get it done now before later...you never know.

You can try my classmate, he's into termite treatment and pest control. Kerry Kua at 016 252 0344. Cheers.
