When a bed bug infestation has spread beyond one room — or when chemical treatments have failed — fumigation is often the most reliable solution. Bed bug fumigation involves sealing the entire structure (tenting) and introducing sulfuryl fluoride gas, which penetrates every crack, void, and piece of furniture in the home, killing all bed bugs in all life stages including eggs. Unlike heat treatment, which requires specialized equipment and careful monitoring of temperature distribution, fumigation reaches every corner of the structure uniformly. It is the same process used for drywood termite fumigation and is performed by licensed pest control operators.

The fumigation process typically takes 24 to 72 hours from start to finish. The pest control company will tent your home, introduce the gas, maintain it at the required concentration for the required time, then ventilate the structure and test air quality before allowing re-entry. You will need to vacate the home (including all pets) for the duration, bag or remove all food, medications, and plants, and follow specific preparation instructions from your provider. After fumigation, there is no residual protection — bed bugs can re-infest if they are brought back in on luggage, clothing, or used furniture. A follow-up inspection 2-4 weeks later is strongly recommended.

The cost of bed bug fumigation in Arizona typically ranges from $1,500 to $4,000 or more depending on the size of the home and the severity of the infestation. This is higher than chemical treatment but may be more cost-effective for severe or widespread infestations that would require multiple chemical treatment visits. Heat treatment is a comparable alternative that does not require tenting but costs similarly. For smaller, localized infestations, chemical treatment with follow-up visits is often the most cost-effective approach.
