My old house comes with rentokil 10 years warranty(developer). Well, termites still came within 5 years. Crap, the warranty doesnt cover the damage and they just respray it.

Anyway, I got fedup as termites will comes back again after a few year but since I went for drilling method, it had been good.

The only disadvantage about drilling method, they might accidentally drill and hit your water pipes. Trust me, I have to curse and swear those idiots and the incovenience they caused me and I even have to repipe my piping at my own cost. That company didnt even bother to pay me a single cent.

Unless you know very well where your underground pipe are laid, I wouldn't advise folks to try drilling method.

My new home, I am not bother with termites control as I make sure there is no wood in my home.
