The answer to 'fire ant extermination cost' is that the cost can vary widely depending on several factors. In general, professional fire ant treatment for a typical home can range from around $100 to $500 or more. The exact cost will depend on the size of the affected area, the severity of the infestation, the treatment method used, and your location.
For smaller infestations, do-it-yourself options like baits or granular treatments may cost $50 or less.
