Pest control costs $150 to $500 for a one-time treatment and $40 to $70 per month for an ongoing quarterly or monthly service plan. The national average for a one-time general pest treatment is roughly $250 to $400. The average monthly fee for a recurring pest control plan is $40 to $60. The cost varies by the type of pest, the size of the house, the severity of the infestation, the treatment method required, and the local market. A one-time spray for ants in a 1,500-square-foot house costs $200 to $300. A whole-structure fumigation for termites in the same house costs $1,500 to $3,500. The pest determines the price, not the house.
The pest control industry sells two fundamentally different products. The first is a one-time treatment — a technician arrives, inspects the property, treats the specific pest problem, and leaves. The second is a recurring service plan — a technician visits on a regular schedule, typically quarterly, and applies preventive treatments around the foundation, the eaves, and the interior baseboards to create a chemical barrier that prevents pests from entering. The one-time treatment is for an active problem. The service plan is for prevention. One is a repair. The other is insurance.
Pest Control Cost by Pest Type
| Pest | One-Time Treatment | Recurring Plan | What Drives the Cost |
| Ants (general — sugar, pavement, odorous house) | $150-$300 | $40-$55/month | Bait stations, perimeter spray, nest location — usually a single visit |
| Carpenter ants | $250-$500 | $45-$65/month | Nest must be located and treated directly; wall drilling may be required |
| Cockroaches | $200-$400 | $45-$65/month | Gel bait, IGR, multiple treatments for German roaches; one visit for American |
| Bed bugs | $500-$1,500 per room | Not applicable — requires 2-3 treatments over 4-8 weeks | Heat treatment or chemical; most expensive common pest |
| Termites — liquid barrier | $800-$1,500 | $40-$60/month (monitoring + retreatment) | Trench around foundation, inject termiticide; labor-intensive |
| Termites — fumigation (whole house) | $1,500-$3,500 | Not applicable | Tent the house, fumigate with sulfuryl fluoride; 2-3 days |
| Fleas and ticks | $150-$400 | $40-$60/month | Interior spray + yard treatment; usually 1-2 visits |
| Rodents — trapping and exclusion | $300-$700 | $40-$60/month | Multiple visits to set traps, seal entry points, remove carcasses |
| Mosquitoes | $200-$500 per yard treatment | $50-$75/month (seasonal) | Fogging or barrier spray; recurring during warm months |
| General preventive (quarterly plan) | $200-$400 initial | $40-$55/month or $100-$150/quarter | Perimeter spray, interior baseboard treatment, web removal, inspection |
Recurring Service Plans: What the Monthly Fee Buys
| Plan Type | Typical Cost | Frequency | What Is Included |
| Monthly | $35-$55/month | Every 30 days | Perimeter spray, interior as needed, free callbacks between visits for any pest problem |
| Quarterly | $100-$160/quarter | Every 90 days | Same as monthly; most common service plan for residential homes |
| Annual | $350-$500/year | One comprehensive visit | Full inspection, perimeter spray, interior treatment — maintenance only |
DIY vs. Professional Pest Control: The Cost Comparison
| Approach | Typical Annual Cost | What It Buys | Best For |
| DIY — hardware store products | $75-$200/year | Sprays, baits, traps — applied by the homeowner | Minor, occasional ant or spider problems; preventive maintenance |
| DIY — professional-grade products online | $100-$300/year | Same chemicals professionals use — non-repellent sprays, IGRs, gel baits | Homeowner willing to learn application techniques and safety precautions |
| Professional quarterly plan | $400-$640/year | Licensed technician, commercial-grade products, inspection, warranty, free callbacks | Recurring pest pressure, busy homeowners, peace of mind |
The free callback is the most valuable feature of a professional pest control contract. If ants appear between quarterly visits — or roaches, spiders, mice, or any covered pest — the technician returns at no additional charge. The callback is what turns a $120 quarterly visit into an insurance policy. If the homeowner treats pests with store-bought products and the ants return, the homeowner buys more products and tries again. If the professional treats the house and the ants return, the professional returns for free. The callback is the difference between a service and a product.
FAQ: Common Questions About Pest Control Costs
Why is the initial pest control visit more expensive than the ongoing visits?
The initial visit is a treatment — the technician identifies the pest, locates the nest or entry points, applies a heavier concentration of insecticide to eliminate the active infestation, and seals entry points if applicable. The ongoing visits are maintenance — a lighter perimeter spray to maintain the chemical barrier and an inspection for new activity. The initial visit takes 60 to 90 minutes and uses more product. The quarterly visit takes 20 to 40 minutes and uses less. The labor and the product consumed are the difference.
Do I need to sign a contract for pest control service?
Most national pest control companies require a 12-month service agreement for recurring plans. The contract typically includes the initial treatment, the scheduled ongoing visits, and free callbacks between visits. The contract can be canceled — usually with a fee equal to one or two months of service. Local, independent pest control companies are more flexible — many offer month-to-month service without a contract, particularly after the initial treatment is complete. Ask about the cancellation policy before signing. An annual contract is not unreasonable. A contract with a punitive cancellation fee is.
$250-$400 for Most One-Time Problems. $400-$640 per Year for Ongoing Prevention.
Pest control costs $150 to $500 for a one-time treatment of a typical household pest — ants, cockroaches, fleas — and $40 to $70 per month for a recurring service plan that prevents pests from entering and treats any that do. The specialist pests — bed bugs ($500 to $1,500 per room), termites ($800 to $3,500), rodents ($300 to $700) — cost more because they require specialized treatment methods and multiple visits. The cost of professional pest control is the cost of the chemicals, the labor to apply them correctly, and the warranty that the pests will not return — or the technician will, for free.
