More Information about Termites in Idaho

According to Termite Infestation Probability Zones (TIP Zones), Idaho is located in TIP Zone #2 (moderate to 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.

Although drywood termites are not established in Idaho, infestations are possible if termites are transported to the state in wooden objects, such as furniture and wine crates. Drywood termites have been found in areas far from their native habitats and climates. A licensed termite inspector can help identify species not native to the state.

In states like Idaho where termites are fairly active and widespread, it is essential to maintain an effective termite prevention and control program. If you own a home in Idaho, talk to your termite control expert about methods to help protect your home from termite infestations and damage.
