Depending on the type of extermination, accessibility and size of a structure, costs for termite treatment range from $1,200 to over $3,000 as of 2014. Chemicals, bait, fumigation and heat are all methods used to stop the damage caused by termites.
Chemical extermination starts on the low end of the price spectrum, typically priced around $1,350 to $2,500 for a 1,250-square foot home. Bait extermination begins around $1,500 and tops out at $3,000 for a 2500-square foot home. Fumigation, like the other types of extermination, has a cost based on the size of the house. For fumigation, the house is generally tented during extermination. Cost for fumigating a 1250-square foot house ranges from $1,200 to $2,500. Heat extermination, which also requires tenting of the house, typically costs $1,250 for a 1,250-square foot house.
Both bait and chemical extermination are done by drilling holes around the house and adding a liquid chemical or bait into the holes. While both are effective, baiting is more expensive and tends to be used only to prevent contamination when a house is near a lake or stream. Fumigation requires the homeowners to leave the home for up to five days, while heat extermination, a newer method, allows for same day re-occupancy.
