Termite Activity in Hawaii
Termites are active on all of Hawaii’s islands: Nihue, Kauai, Oahu, Molokai, Lanai, Maui, Kahoolawe and the Big Island.
What Types of Termites Are in Hawaii?
Subterranean and drywood termites are known to damage homes in Hawaii. Dampwood termites also are common in Hawaii; however, dampwood termites are less likely to damage structures than subterranean and drywood termites.
Are Formosan Termites in Hawaii?
Formosan termites have been present in Hawaii since the mid-1800s. Experts estimate Hawaiian residents and business owners spend $100 million annually to control and repair damage from Formosan termites.
The Formosan termite is active across most of Oahu (including Honolulu) and Kauai islands. On the other islands, where it typically is located near seaports, this species has been identified in Hilo, Honokaa, Kamuela, Kawaihae, Waikoloa, Kona, Kahului, Wailuku, Maalaea, Kihei, Lahaina, Kaunakakai, Kalaupapa and at the Kaumalapau Harbor.

More Information about Termites in Hawaii
According to Termite Infestation Probability Zones (TIP Zones), Hawaii is located in TIP Zone #1 (very heavy), which means the potential for termite damage is considered significant. Areas with higher probabilities for termite activity require more termite control measures to meet International Residential Code building standards for new homes than areas with less frequent activity.
In states like Hawaii where termites are very active and widespread, it is essential to maintain an effective termite prevention and control program. If you own a home in Hawaii, talk to your termite control expert about methods to help protect your home from termite infestations and damage.
