Pest Control Cost in Marietta, GA (2026 Pricing)

Last updated: March 7, 2026

By James — 25-year pest control industry veteran

Pest control cost in Marietta, GA ranges from $90 to $540 for a one-time visit, with the average homeowner paying about $154. Marietta is a historic city northwest of Atlanta in Cobb County, featuring a mix of older homes around the Marietta Square area and newer suburban developments spreading outward. The heavy tree canopy, established landscaping, and proximity to Kennesaw Mountain create abundant pest habitat that drives consistent pressure from termites, fire ants, carpenter bees, mosquitoes, and wildlife throughout the year.

This guide covers local pricing for the most common Marietta-area pests, seasonal patterns, and what homeowners should know about pest control in Cobb County. For national pricing benchmarks, see our pest control cost guide. Marietta is part of the Atlanta metro; see our Atlanta pest control cost guide for broader regional context.

Marietta Pest Control Pricing by Service

Marietta pest control prices run approximately 10% below the national average, consistent with the Southeast regional market. The Cobb County area has a competitive pest control market with both national franchise companies and well-established local operators, which helps keep pricing competitive despite the region's significant pest pressure.

Common Marietta Pests and Treatment Costs

Termites: eastern subterranean and Formosan ($1,080 to $3,150)

Georgia consistently ranks among the top states for termite activity, and Marietta reflects that pressure. Eastern subterranean termites are the primary species, building massive underground colonies in the red clay soil that retains moisture throughout most of the year. Colonies can contain hundreds of thousands of workers foraging up to 300 feet from the nest. Termite swarms are most visible from March through May, when winged reproductives emerge in large numbers.

Formosan termites are a growing concern in the Cobb County area. Originally concentrated in coastal Georgia, Formosan colonies have been spreading northward into the Atlanta metro. They are more aggressive than eastern subterranean termites, with larger colonies that can cause structural damage more rapidly. The mix of historic homes near the Marietta Square and established post-war suburban construction means a large percentage of the housing stock has older, unprotected wood framing. Liquid barrier treatment is the standard approach, with bait station monitoring used as a supplement. See our termite treatment cost guide and our Atlanta termite treatment cost guide for detailed pricing.

Mosquitoes ($135 to $315 one-time)

Mosquito pressure in Marietta runs from April through October, peaking in June through August after heavy rainfall. The area's many creek corridors, including Noonday Creek, Proctor Creek, and numerous smaller branches that drain wooded subdivisions, provide sustained breeding habitat. Homes adjacent to wooded lots, retention ponds, or drainage easements have significantly higher mosquito activity than those in open, well-drained areas.

Monthly barrier spray services ($40 to $75/month) are popular during the six-month peak season. One-time treatments cost $135 to $315 and provide protection for approximately three to four weeks. Source reduction, including eliminating standing water in gutters, bird baths, and low spots in yards, is essential for any treatment program to be effective. See our mosquito treatment cost guide.

Cockroaches ($90 to $540)

American cockroaches and German cockroaches are both present in Marietta. American cockroaches (the large, reddish-brown species sometimes called smoky brown cockroaches in Georgia) are common in basements, crawl spaces, and utility rooms. They enter through floor drains, sewer connections, and gaps around pipes. German cockroaches are the smaller indoor species found in kitchens and bathrooms, requiring targeted gel bait treatment for effective control.

Older homes in the downtown Marietta area and close-in suburban neighborhoods tend to have more cockroach pressure due to aging infrastructure and more entry points. Treatment costs $90 to $540 depending on species, severity, and home size. See our cockroach exterminator cost guide.

Carpenter bees ($90 to $270)

Carpenter bees are one of the most common structural pest complaints for Marietta homeowners, particularly those with older homes featuring exposed wood elements such as fascia boards, porch ceilings, deck joists, pergolas, and wood railings. Female carpenter bees drill perfectly round half-inch holes into bare or weathered wood to create nesting galleries. They do not eat the wood but excavate deep tunnels that weaken structural members over time.

Marietta's historic downtown neighborhoods and older suburbs have abundant carpenter bee habitat. The same nest sites are reused year after year, with galleries extended by each new generation. Treatment costs $90 to $270, involving insecticidal dust applied into active galleries and sealing the entry holes after treatment. Painting, staining, or caulking exposed wood surfaces is the most effective prevention measure.

Ants: fire ants and carpenter ants ($135 to $270)

Red imported fire ants are pervasive throughout Cobb County. They build mounds in lawns, garden beds, along fence lines, and near foundations. Mounds appear rapidly after spring and summer rains, and their stings are painful and medically significant for children, pets, and people with venom allergies.

Carpenter ants are present in wooded Marietta neighborhoods, nesting in moisture-damaged wood, dead trees, and structural timbers with water intrusion. Unlike termites, carpenter ants do not eat wood but excavate smooth galleries for nesting. They are often a sign of an underlying moisture problem. Treatment costs $135 to $270 for targeted ant service, with broadcast bait applications in spring and fall providing the best yard-wide fire ant control.

Wildlife: raccoons and squirrels ($180 to $540)

Marietta's heavy tree canopy and proximity to Kennesaw Mountain National Battlefield Park create conditions where wildlife conflicts are common. Raccoons and squirrels are the most frequent attic invaders, entering through gaps in rooflines, deteriorated soffits, and construction gaps. Raccoons can cause significant damage to attic insulation, ductwork, and wiring once they establish a den.

Squirrels chew through fascia boards, soffit vents, and even roof sheathing to access attic spaces. They gnaw on electrical wiring, creating fire hazards. Established landscaping with mature hardwoods provides easy roof access via overhanging branches. Wildlife removal costs $180 to $540 depending on the species and the extent of exclusion work needed to prevent re-entry. Georgia law requires licensed wildlife control operators for raccoon removal.

Marietta Seasonal Pest Calendar

Pest activity in Marietta is year-round but peaks from spring through fall. Termite swarm season (March through May) is the most critical window for inspections and preventive treatment. The heavy tree canopy and wooded lots that define many Marietta neighborhoods sustain pest populations even during cooler months.

Cost Factors in Marietta

• Older homes need more sealing. Pre-war historic homes near the Marietta Square and post-war construction through the 1970s have more pest entry points, older wood framing without treatment history, and crawl spaces that require additional inspection and sealing work. Newer slab-on-grade construction generally costs less to treat and maintain.
• Larger wooded lots increase treatment costs. Heavily wooded lots near Kennesaw Mountain and creek corridors provide harborage for termites, mosquitoes, rodents, and carpenter bees. Larger properties cost more to treat for fire ants and mosquitoes, and face higher ongoing termite risk from nearby colony food sources in dead wood and stumps.
• Heavy tree canopy creates pest habitat. Marietta's established landscaping and mature hardwoods provide food, shelter, and roof access for wildlife, squirrels, carpenter bees, and mosquitoes. Overhanging branches give wildlife and rodents direct pathways to rooflines and attic entry points.
• Proximity to Kennesaw Mountain preserves. Properties bordering the national battlefield park are adjacent to a large undeveloped green space that sustains wildlife and pest populations, including deer ticks, mosquitoes, raccoons, and rodents that migrate into residential neighborhoods.
• Red clay soil and foundation type. Georgia red clay retains moisture and supports large subterranean termite colonies. Homes with crawl spaces face higher pest pressure than slab-on-grade construction, as crawl spaces provide direct soil contact for termites and sheltered harborage for rodents and cockroaches.

Tips for Choosing a Pest Control Company in Marietta

• Verify Georgia Department of Agriculture licensing. Georgia requires all pest control companies to be licensed by the Georgia Department of Agriculture. Verify the company's license status before signing any service contract.
• Ask about termite experience. Given Georgia's high termite pressure, including the spread of Formosan termites, choose a company with demonstrated experience in both liquid barrier treatment and bait station monitoring. Ask about their inspection process and warranty terms.
• Confirm WDI report capability. If you are buying or selling a home in Cobb County, confirm the company can produce WDI (Wood Destroying Insect) reports, which are standard in Georgia real estate transactions.
• Ask about wildlife removal licensing. Georgia requires separate licensing for wildlife control operators. If you need raccoon, squirrel, or other wildlife removal, confirm the company holds the appropriate wildlife control permit.
• Get at least three quotes. The Marietta and Cobb County area has a competitive pest control market with both national and local companies. Quotes for quarterly service on the same home can vary by 30 to 40 percent between providers.
