$150 – $300 | Single Visit |

Cost by Pest Type
Termite Treatment Costs
Termite work is highly specialized. Costs depend heavily on whether you need “spot treatment” or full “structural fumigation.”
- Inspection: $75 – $150 (Often free if you hire the company).
- Spot Treatment: $400 – $900 for localized orange oil or chemical treatment.
- Whole House Fumigation (Tenting): $1,500 – $4,000+. This depends on the square footage (approx. $1.50 – $4.00 per sq. ft.).
Bed Bug Extermination Cost
Bed bugs are the most expensive standard pest because they require intensive labor. Most companies charge per room.
- Chemical Treatment: $300 – $500 per room.
- Heat Treatment (Whole House): $2,000 – $5,000. This is the most effective method but carries a higher price tag.
Rodent Removal (Rats & Mice)
Costs typically include an inspection, trapping, and “exclusion” (sealing holes).
- Initial Trapping: $250 – $450.
- Exclusion/Sealing Work: $200 – $1,000+ depending on the repair work needed (roof vents, screens, drywall).
Other Common Pests
Expect standard pricing ($150 – $300 per treatment) for pests that require exterior barrier sprays and light interior work, such as:

4 Hidden Pest Control Fees to Watch For
When getting a “pest control estimate” over the phone, ask about these charges to avoid surprises:
- Initial Start-Up Fee: Most monthly plans require a higher first payment (often $150+) to bring the infestation under control before maintenance begins.
- Size Surcharges: Quotes are often for homes under 2,000 sq. ft. If your home is larger, expect a 10-20% surcharge.
- Retreatment Fees: A good contract includes free “call-backs” if pests return between visits. Avoid companies that charge $35+ for these extra visits.
- Termite Warranty Renewal: If you pay for termite treatment, the annual warranty renewal (to keep protection active) usually costs $150 – $300 per year.
Is DIY Pest Control Cheaper?
Many homeowners ask, “How much does an exterminator cost vs. doing it myself?”
- DIY Cost: $50 – $100 for sprays, traps, and bait.
- Pro Cost: $150 – $300.
The Verdict: DIY is cheaper for minor issues (like a few ants in the kitchen). However, for recurring infestations or dangerous pests (rats, termites, bed bugs), professional treatment is cheaper in the long run because it prevents structural damage and repeated product purchases.
