Will termites eat treated wood?
Pressure treated wood is infused with chemical preservatives that make it more termite resistant. However, it is by no means termite proof. Pressure treated wood is typically used where ground contact will be experienced and the extra protection is desired. It should be noted that not even the manufacturers will claim the wood to be termite proof. The elements, such as water, will degrade the protection offered by the pressure treatment and will leave the wood vulnerable to termites.
