Direct Answer: You cannot tent a house every 5 years and call it 'sustainable.' The only way to win the war against Florida termites is to starve them. Don't build their lunch.

The "Super Termite" Threat
In the Northeast, termites are a nuisance.
In Florida, they are a structural crisis.
The Formosan Subterranean Termite is aggressive. They build colonies in the soil and in the walls (if there is a moisture source). They can eat the framing out of a house before you even see a mud tube.
The Problem with Block
"But I'm building with block, I'm safe, right?"
Wrong.
In a standard block home, the interior walls are framed with wood furring strips.
The termites enter through microscopic cracks in the slab or block mortar.
They find the dark, moist space behind the drywall.
They eat the furring strips. Then they eat the paper off the drywall. Then they eat the kitchen cabinets.
You are paying for an exterminator for the rest of your life.
The ICF Immunity
ICF walls are chemically inert.
1. Concrete Core: Termites cannot chew through it.
2. EPS Foam: No nutritional value.
3. Plastic Webs: Inedible.
When you delete the wood studs/furring, you delete the attraction.
If a termite colony finds your foundation, they will move on to your neighbor's wood-frame house because it smells like food.
The Hidden Cost of Poison
To protect a wood house, pest control companies inject hundreds of gallons of termiticide into the soil under your foundation.
They drill holes in your patio to pump more poison.
Do you really want your children and pets playing in that?
ICF is the mechanical solution to a biological problem.
No poison. No tenting. Just concrete.
Builder Tip: Ask for "Polyguard" or similar physical termite barriers at the seamless slab-to-wall connection. It forces any termites out into the open where you can see them, preventing hidden entry.
