House fumigation cost

Fumigation costs $1 to $4 per square foot or $2,000 to $8,000 for an average 2,000 SF house. The cost to fumigate a house includes tenting the entire house and using pesticides to completely exterminate the pests. Fumigation is used to treat termites, bed bugs, dust mites, fleas, and roach infestations.

House fumigation costs
Home size (square feet) Average treatment cost
1,200 $1,200 – $4,800
1,500 $1,500 – $6,000
1,800 $1,800 – $7,200
2,000 $2,000 – $8,000
2,500 $2,500 – $10,000
3,000 $3,000 – $12,000
4,000 $4,000 – $16,000

Cost data is from research and project costs reported by HomeGuide members.

During the fumigation process, the house is sealed with a tent or tarps and filled with pesticides over 1 to 3 days. The home must be free of people, pets, and plants until it is completely ventilated after fumigation.

Fumigation cost factors

Tent fumigation prices are based on the square footage of the home, so the bigger the home the more costly the treatment. Other factors that impact the cost of fumigation include:

  • Pest type – Some pests like bed bugs and termites are more difficult to treat, requiring more costly pesticides and longer treatment times.

  • Infestation severity ­– More severe infestations increase the tenting duration and fumigation frequency.

  • Home structure – Fumigation is only effective when the entire structure is treated. Homes with attached decks, porches, attics, and crawlspaces are more expensive to treat.

  • Temporary housing – Tenting requires you and your pets to leave the home for 24 to 72 hours until the home is free of harmful chemicals.

  • Fumigation company – Some of the most popular fumigation companies include Terminix, Orkin, and Erlich:

    • Terminix is one of the largest pest control companies in the US offering a variety of pest control services, including fumigation.

    • Orkin is another large company offering fumigation. The company has more than 400 locations and has been providing pest control services for more than 100 years.

    • Ehrlich is a national pest control company that is known for their use of environmentally friendly pest control methods.

  • Additional costs – Extra fees apply for home repairs, moisture removal, and house cleaning which are common after a severe infestation.

Pest type

Fumigation is a costly pest control method that is typically reserved for infestations of stubborn pests like bed bugs and termites. However, homes with severe infestations of other pests like ants, cockroaches, and dust mites may benefit from fumigation treatment.

Fumigation prices vary depending on the type of pests you have, as shown in the table below.

Fumigation costs by insect type
Pests Average treatment cost
Bed bug fumigation cost $4,000 – $16,000
Termite tenting cost $2,000 – $8,000
Ant fumigation cost $1,500 – $4,000
Carpet beetles $1,500 – $3,000
Cockroach fumigation cost $1,000 – $3,000
Dust mites $1,500 – $3,500
Flea fumigation cost $1,500 – $4,000
Silverfish $2,000 – $3,000
Spiders $2,000 – $4,000
Ticks $2,000 – $6,000

Fumigation frequency

Fumigation is a highly effective pest control method that typically only takes one treatment. However, some pests are more resilient than others, like bed bugs, which may take multiple treatments to completely eradicate the pests.

Once the initial fumigation is complete, exterminators recommend ongoing pest control services. The average cost for pest control is $40 to $75 per month. Depending on the pest type, your pest control company may recommend monthly, quarterly, or annual treatments.

When to fumigate

Fumigation is a serious and costly pest control treatment that is often used as a last resort. Some signs may indicate your home needs fumigation, including:

  • Seeing pests or droppings

  • Damage from termites or rodents

  • Unexplained smells

  • Health or breathing problems

  • Peeling or bubbling paint

  • Itchy bites

  • Molted skins

  • Blood spots on linens

Preparing for fumigation

Before you have your home tented for fumigation, be sure to:

  • Arrange another place to stay for 24 to 72 hours.

  • Pack anything you may need during that time since you won't have access to your home.

  • Remove any food, drinks, and medicine from the home or store them in airtight containers.

  • Seal all cracks or openings around windows or doors with duct tape or plastic sheeting to prevent the fumigants from escaping.

  • Turn off all utilities including electricity, gas, and water for safety.

Types of fumigation treatments

Fumigation is the best process for complete pest removal for severe infestations in the entire home. Pest control professionals use three types of fumigation, including gas, solid, and liquid fumigants.

Gas fumigation

Gas fumigation is the most well-known fumigation method. The gas pesticide, usually methyl bromide, permeates every corner and crevice to kill the targeted insects and rodents.

Solid fumigation

Solid fumigation is easier and safer than gas fumigants but is less effective. Solid fumigants include aluminum phosphide and calcium cyanide in tablet, powder, or pellet form. These solid fumigants are vaporized with heat or moisture.

Liquid fumigation

Liquid fumigation involves spraying large quantities of toxic chemicals over an area to eradicate pests. Liquid fumigants act faster than solid fumigants. The liquid chemicals often include carbon disulfide, chloroform, ethyl acetate, and sulfuryl fluoride.

Most liquid fumigation chemicals are flammable, volatile, and toxic to humans and must be used with care.

Fumigation alternatives

Whole-home gas fumigation kills pests in every life stage but is not recommended in homes with pregnant women or children because of the harmful pesticides. Heat treatment is a safe alternative for those homes, using heat to suffocate the pests.

Other tentless treatment options include chemical soil treatment and bait stations to create a barrier against infestations, and micro treatments to kill localized colonies.

Fumigation FAQs

What is fumigation and is it safe?

Fumigation is a pest control method in which the entire home is tented and filled with fumigants to poison the pests within. The fumigants are toxic to humans and pets, so a professional pest control company is recommended.

How long does fumigation take?

Fumigation takes from 24 to 72 hours, including setting up the tent, treating pests, and ventilating the home before you can safely return.

What can be left in the house during fumigation?

All people, pets, and plants must be removed from the home during fumigation since the chemicals used are toxic. Food, drinks, and medicines stored in airtight containers are safe to stay. Clothing, furniture, electronics, and hygiene items like toothpaste and shampoo can be left in the house during fumigation.

How do I clean after fumigation?

Once the air is clear and no fumigants remain, you can return home, open the windows, and begin the cleanup. Wear gloves and a mask as you perform the following tasks:

  • Remove any dead pests.

  • Wipe down all surfaces with a damp cloth.

  • Clean the appliances.

  • Launder clothes and linens in hot water and detergent.

  • Mop the floors with warm soapy water.

  • Check for lingering odors and use an odor neutralizer like baking soda if needed.
