Termite Tent Fumigation in Hercules — FAQ

How much does termite fumigation cost in Sacramento?+

Fumigation typically costs $1-$3 per sq ft. A 1,800 sq ft home costs roughly $1,800-$4,500. Pricing depends on structure size, number of stories, roof pitch, and accessibility.

How long do I need to be out of my house?+

Plan for 2-3 nights. The gas holding period is 24-48 hours, followed by 6-12 hours of aeration. Your fumigator will issue a written re-entry notice once air testing confirms safe levels.

Is fumigation safe for my home?+

Yes. Vikane gas does not leave residue on surfaces, fabrics, or building materials. It dissipates completely during aeration. The only items that need removal are consumables (food, medicine, pet food).

Will fumigation kill subterranean termites too?+

No. Fumigation targets drywood termites that live inside the wood. Subterranean termites live in the soil and require a separate treatment (liquid barrier or baiting system).
