More Information about Termites in Iowa
According to Termite Infestation Probability Zones (TIP Zones), the southern two-thirds of Iowa are located in TIP Zone #2 (moderate to heavy), which means the potential for termite damage is considered significant. The northern one-third of the state is located in TIP Zone #3 (slight to moderate), which means there is some potential for damage by termites. Areas with higher probabilities for 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 Iowa, it is possible for this species to travel in wooden objects, such as furniture and wine crates, and establish colonies in the state. Drywood termites have been found in areas far from their native habitats. A licensed termite inspector can help identify species not native to the state.

In states like Iowa 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 Iowa, talk to your termite control expert about methods to help protect your home from termite infestations and damage.
