Termites will not eat pressure treated wood unless it’s cracked, damaged, or rotting.
Pressure-treated wood is resistant to decay and termites.
It’s gone through a process that uses high pressure to force preservative chemicals deep into the pores of the wood.
These chemical solutions slow down natural decay and protect the wood against fungus, moisture, and termites.
That said, pressure-treated wood is “termite-resistant,” not “termite-proof.”
The chemicals will slowly dissipate over several years, making the wood vulnerable over time.
If there is any crack on the wood, the termites can bypass the external barrier and enter it. While this is rare, it can happen.
Still, some protection is better than none.
And, despite its flaws, using pressure-treated wood is undoubtedly a great strategy to keep termites away.
For the most natural and tested chemical against termites, wood treated with borates has been proven to be extremely useful.
