Once a termite infestation is identified, it can be difficult to determine how long the colony has been established in the home. Typically, colonies take more than five years to grow to a size capable of causing damage. Two recent statistics on termite damage on a national and per homeowner level include:

1. Each year, termites and similar pests cause an estimated $30 billion in damage to crops and man-made structures in the U.S. Home and Wild fires do only 7 billion in damage per year.

2. A homeowner who discovers termite damage will spend an average of $3,000 to repair the damage. Termite treatment programs average from $450-$1500.
