To effectively exterminate moths, most homeowners can pay between $200 and $370, with an average cost of $150, depending on the infestation's severity, treatment method, and location. Key cost factors include the level of infestation, chosen extermination method, and accessibility of affected areas. Professional moth extermination can help prevent further damage to your clothing, carpets, and stored goods.
A variety of factors impact how much you’ll pay to exterminate moths. Here’s a closer look at the cost breakdown.
Some moths are easier to treat than others. For example, pantry moths are notoriously difficult to kill because they easily spread from one dry good to another, leaving eggs behind. For this reason, the type of moth you are dealing with will influence the cost of pest control treatment.
How bad your moth infestation is also contributes to how much you’ll pay for moth extermination. For example, a carpet moth treatment in just one room will cost less than treating your entire home. This is another reason, in addition to the damage they can cause, that it’s important to seek moth treatment sooner rather than later.
The more work a technician needs to perform to treat your moth problem, the more you’ll pay for treatment. A good example involves home fumigation. The more furniture the tech has to move or the more aerosol cans they need to set up, the more the treatment cost will go up.
The treatment method your technician uses also affects the cost of moth extermination. Parasitic wasp treatment is actually one of the least expensive methods because it only involves placing cards around the infested area. Moth fumigation costs more because it takes more active effort to prepare and treat the house.
There are four primary methods of moth control. A pest control technician can advise you on which method best suits your needs based on the location and level of your infestation.
This method of moth extermination costs $90 to $100 and involves placing cards containing Trichogramma eggs around the infested area. The wasps will hatch and grow, and then after mating, the female wasps will leave the cards to seek moth eggs in which to lay their own eggs.
Parasitic wasps, specifically Trichogramma species, are an effective method of eliminating a moth infestation. These tiny, non-stinging wasps lay their eggs inside moth eggs, disrupting the moths' life cycle. Once they have eradicated the moth infestation in your home, the wasps will naturally die off, leaving no residual presence.
Heat treatment averages $120 to $300, and is a safe and effective option if you are dealing with clothes moths or carpet moths. The cost for this treatment will depend on the treatment volume (for clothing, curtains, and other textiles) or area (for carpets, closets, and other spaces).
During a heat treatment, a moth exterminator will remove any contaminated items from the treatment area. Professionals hang clothing and textiles on racks for treatment, while carpeted areas are treated with powerful heaters. Treatments last 30 minutes to an hour and are effective because they kill moths at all developmental stages, from egg to adult.
Assuming you have a standard-sized yard, you can expect to pay $100 to $250 for chemical treatment. In some cases, you may be able to solve your moth problem with just a single treatment. For particularly serious infestations, a lawn tech may need to return several times to ensure complete eradication.
If you’re dealing with moths outside of your home, typically within the lawn or in trees, your exterminator will generally elect for a chemical treatment. Most moth control technicians spray professional-grade pesticides like bifenthrin to kill the moths.
The average cost for moth fumigation is $150 to $350 if you’re treating just one area or $350 to $500 if you’re treating the whole house.
When you have an issue with brown moths, pantry moths, and other moths that take up residence inside your home, a local pest control technician may decide that fumigation is the best option. Depending on the severity of the infestation, the tech may suggest fumigation alongside other treatment methods, such as heat treatment or moth traps.
After having you remove or cover items that the treatment may contaminate, the technician will use a pesticide in fog or mist form. They may apply it using a wand and sprayer or by activating aerosol cans. Once the chemical has dissipated, which takes a few hours, you’ll be allowed back into your home.
While some minor moth infestations can be addressed with DIY methods, professional extermination often ensures more effective results. Pest control professionals charge $50 to $75 per hour, and while this may seem costly, the expenses of DIY treatments, including equipment like sprayers or spreaders, can be comparable.
Clothes moths are particularly challenging to eliminate due to their tendency to lay eggs deep within fabrics and carpets. DIY approaches, such as using space heaters, may not provide sufficient heat to eradicate the infestation fully. Moreover, treating moth infestations is not a task for everyone. It can be difficult to pinpoint the source of the infestation or identify the moth species you are dealing with.
Considering that pest control technicians have the knowledge and experience to address moth infestations effectively, hiring a professional is a more efficient and cost-effective solution.

Fumigation is not always necessary to eliminate moths. While it is an effective method for treating moth infestations, it is not required in every situation. Moth problems involving fabrics may be addressed with alternative treatments, such as parasitic wasps that target the eggs directly. Fumigation requires protecting valuable items and temporarily vacating the area until the chemicals disperse safely.
The time required to eliminate moths depends on the selected treatment method and the severity of the infestation. When a parasitic wasp treatment is applied, the process may require two months for complete eradication. Heat treatments deliver immediate results by killing moths at every developmental stage, from egg to adult, providing rapid relief from the infestation.
A moth infestation reveals itself through a range of visible signs and demands a careful inspection. Carpet moths leave small holes in fabrics, while lawn moth damage appears as patches of brown or dead grass. When moths affect trees, they cause leaves to drop rapidly, alerting homeowners to a developing problem. These patterns of damage clearly indicate that an infestation is present.
To prevent recurring moth infestations, you should seal cracks in the exterior of your home, keep windows and doors closed, and eliminate potential food sources that attract moths. Incorporate regular cleaning and the use of approved moth repellents, and consider establishing a service contract with a pest control professional to keep your home protected against future infestations.
