Fumigation vs. Heat Treatment for Termites in Miami

By Miami Pest Control Pros | Updated January 2025 | 7 min read

For drywood termite infestations in Miami, two whole-structure treatment methods are available: tent fumigation with Vikane (sulfuryl fluoride) gas, and heat treatment (thermal remediation). Both methods kill all drywood termite life stages — including eggs — throughout the entire structure. Choosing between them depends on your specific property, budget, schedule, and preferences. This guide explains exactly how each works and when one is preferred over the other.

Side-by-Side Comparison

Factor	Tent Fumigation	Heat Treatment
How it kills termites	Vikane gas penetrates all wood, killing by disrupting cellular respiration	Raises structure to 118–122°F; kills all life stages through heat
Tenting required?	Yes — tent must cover the entire structure	No tent; targeted or whole-structure heating
Time out of home	2–3 nights	Typically 6–8 hours; same-day return
Chemical residue after?	No — Vikane gas dissipates completely; no residue	No — heat treatment only; no chemicals
Kills all termite species?	Yes — drywood, subterranean, all wood-boring insects	Yes — all species within the heated zone
Ongoing protection?	No residual after treatment; new termites can re-enter	No residual; same limitation
Typical cost (Miami)	$1,200 – $3,500+	$800 – $2,500
Items to remove	Food, medicine, plants, pets — detailed prep list required	Plants, some electronics; less extensive
Available for all structures?	Most CBS and frame structures; some tile roof homes require prep	Best for standard structures; some limitations for larger complex buildings

Fumigation — How It Works and When to Choose It

Whole-structure fumigation with Vikane (sulfuryl fluoride) has been the standard drywood termite treatment in Florida for decades. A tarpaulin tent is sealed over the entire structure, Vikane gas is introduced at a calculated concentration, and the tent remains in place for 24–72 hours. The gas penetrates all wood members throughout the structure — inside wall framing, roof framing, furniture, and any wood element — killing all drywood termite colonies and all insect life regardless of location.

After the treatment period, the tent is removed, the structure is aerated, and gas levels are tested before re-entry is cleared. Vikane gas dissipates completely — no chemical residue remains in the structure.

Choose fumigation when:

• The infestation is extensive or affects multiple areas throughout the structure
• The specific location of all colonies is unknown (fumigation reaches everywhere)
• The home is a larger structure where heat treatment equipment cost becomes significant
• You want the most established and documented whole-structure treatment method

Heat Treatment — How It Works and When to Choose It

Thermal remediation raises the air temperature inside the structure to 120°F+, which penetrates into wood and kills all termite life stages including eggs. Electric heaters and fans are placed throughout the home, raising and maintaining temperature for 6–8 hours while temperature is monitored in multiple points to confirm kill zones are reached throughout the wood.

No chemicals are used, no tent is required, and residents can typically return the same day the treatment is completed — often by evening.

Choose heat treatment when:

• You cannot or prefer not to vacate the home for 2–3 nights
• You prefer no chemical use of any kind
• The infestation is more localized and specific rooms can be targeted
• You have a short-term rental or hotel property where same-day return matters
