What's more, some homes - especially older ones - have more than one colony at work. So even if one known colony is destroyed, your home still may not be secure.

Because termite colonies - and all their members - are so hard to locate, spot treatments often achieve only partial results. Spot treatments using chemicals, freezing, heating, microwaves and electrocution may successfully kill the termites they reach. But, as we know, some termites cannot be located. And the ones that are found may be beyond the range of a spot treatment.

If a colony is only partially destroyed, it can rebuild and continue to cause damage. It takes as few as 20 survivors to start producing eggs.

So, even if an inspector finds a gallery and can reach it with his or her equipment, many termites may survive and start a new colony. To make matters worse, many spot treatments risk damage to your home and belongings.

Unlike spot treatments, Vikane gas fumigant spreads into every nook and cranny of your home to kill every termite. It penetrates into the pores of wood, altering the termites' breathing space. No termites are beyond its reach. And none are left behind to start a new colony.

In fact, Vikane is the treatment of choice for many centuries-old historical sites, where multiple hidden colonies have foiled spot treatment attempts.

No other drywood termite treatment compares to Vikane. Vikane has been proven in 25 years of university research, published reports and practical use on homes like yours.
