The cost of fumigating a house ranges from $2,000 to $8,000 for an average 2,000-square-foot home. The exact cost of fumigation depends on a number of factors including the size of your home, the type of pest you are dealing with, and the severity of the infestation.

Expect to pay around $1 to $4 per square foot for fumigation services. Fumigation is the most expensive pest control method but is often the best method to treat stubborn pests or severe infestations. Pests such as termites or bed bugs are more difficult to control and will incur higher fumigation costs. Tenting fumigation is typically more costly than tarping but is more effective at killing every pest in the home.

Fumigation is a whole-house pest control method for severe pest infestations and stubborn pests like bed bugs or termites. The entire home is sealed with a tent or tarps and the space is filled with chemicals that kill the bugs and their eggs throughout the home. Pest control professionals use gas, solid, or liquid fumigants but gas fumigation is the most common method.

After the treatment, most pest control specialists will follow-up with repeat inspections to make sure there is no re-infestation. Since a single pregnant female can quickly cause a repopulation, the follow-up inspections are a critical step in maintaining a pest-free home after fumigation.

Fumigation takes from 24 to 72 hours, depending on the pests being treated. This time includes setting up the tent, treating the home with fumigants, and ventilating the home. Some severe infestations for more difficult pests can take repeated treatments, extending the period that the house is tented.

While the fumigation process takes 1 to 3 days or more, the treatment should last for several months or longer, depending on the severity of the infestation. Most pest control companies will continue to provide regular inspections after a fumigation to ensure no pests were left behind to repopulate. Quarterly or annual pest control plans are common after a fumigation to prevent another infestation.

Fumigation uses toxic chemicals, so all people, pets, and plants must be removed from the home. Food, drinks, and medicines should be removed or stored in airtight containers to keep them safe. Hygiene items like toothpaste and shampoo are not affected by the chemicals and can be left in the home.

Appliances and electronics are not damaged by the chemicals and are safe to leave at home during fumigation. Clothing and bedding should also stay in the home so that any pests living in the fabrics are treated. However, fabrics will have a lingering scent and will require laundering when you return home.

When choosing a fumigation exterminator, be sure to ask these important questions:

• How long have you been using fumigation for pest control?
• Do you have a list of customer references with phone numbers?
• Will the tech treating my home be certified or licensed?
• How much will the tenting and fumigation cost?
• Will I need any follow-up services after the initial fumigation?
• Do you come back later to check for reinfestation?
• How long will I be out of my home?
• Do I need to take all the food out of my pantry before you fumigate?

Seek help from an experienced fumigator before the unwelcome pests cause damage to your home. Follow these recommendations to find the best fumigator for your pest control needs:

• Look for licensed, insured, and bonded exterminators that regularly use fumigation methods.
• Inquire about their fumigation expertise, services, fees, and payment options.
• Confirm they specialize in tenting fumigation.
• Check their references and reviews from past clients on Google and HomeGuide.
• Discuss their recommendations for ongoing monthly, quarterly, or annual treatments.
