Even the most widely advertised alternatives to EXTERRA, liquid applied termite control chemicals, come up short when it comes to the extent of their effect on a termite colony. Sure, they can kill the termites that are in your home now, and a lot of the termites in the ground under it, but they haven't been demonstrated to eliminate entire termite colonies in the ground where they originate. The creation of the EXTERRA Termite Interception Zone ensures that protection is ongoing, where as chemical deposits age in the soil and breakdown. This means chemicals eventually reach a point where they no longer affect the termites, and once more the termites return to attack your home.
There is not one published, peer reviewed scientific paper demonstrating colony elimination of our economically important local termite species with any liquid applied termite control product on the market today. In fact the performance claims on the registered product labels for these liquid chemicals (claims which have to be supported by trial data for review and approval by leading, independent scientists) make no claim whatsoever regarding colony elimination!
Rest easy, the answer is no. The EXTERRA Stations are there to protect your home and will only intercept those termites that have entered into and are actually foraging in your garden. If the Stations weren't there, then these termites would eventually seek out and attack your home.
The FOCUS evolves the gaseous attractant that termites adore over a 2 m radius. Thus, when the EXTERRA Stations are placed around your home, they link together to form the EXTERRA Termite Interception Zone™, protecting your home. EXTERRA then does its job naturally by directing termites to the Stations and not to your home, luring them to their "Last Supper"
If you choose another baiting system, the termites are likely to pass between the small stations and again find their way into your home. This is because the Termite Interception Zone that stops termites passing between our Stations is unique to EXTERRA and protected by international patents.
