More Information about Termites in Colorado
According to Termite Infestation Probability Zones (TIP Zones), roughly one-third of Colorado is located in TIP Zone #2 (moderate to heavy), which means the potential for termite damage is considered significant. Another third of the state is located in TIP Zone #3 (slight to moderate), which means there is some potential for damage by subterranean termites. 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 throughout all of Colorado, it is possible for them to spread through transported wooden objects, such as furniture and wine crates. Drywood termites have been found in areas far from their typical native habitats. A licensed termite control expert can help identify species not native to the area.
In states like Colorado 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 Colorado, talk to your termite control expert about methods to help protect your home from termite infestations and damage.
