Pest Control in Gretna, LA
Gretna grew out of a plantation subdivided into lots in 1836 by surveyor Benjamin Buisson for landowner Nicholas Noel Destrehan, first known as Mechanikham and settled heavily by German immigrants before formal incorporation in 1913. The Old Gretna Historic District that survives from that era covers 130 acres and 737 buildings, 553 of them contributing structures built between about 1845 and 1935, and a levee along the Mississippi River still separates the town's oldest blocks from the water that shaped its growth as a rail and ferry crossing to New Orleans.
Gretna's oldest neighborhood is old enough that some of its buildings predate the Civil War by about fifteen years, and that history is the reason pest control here looks different than it does in a newer Jefferson Parish subdivision. Old Gretna, a 130-acre historic district across the river from New Orleans, holds hundreds of Creole cottages, shotgun houses, and commercial buildings dated between roughly 1845 and 1935, tightly packed on lots surveyed back when the town was still called Mechanikham. A century or more of exposure to Gulf South humidity and river-driven moisture gives Gretna's older wood-frame buildings a level of termite exposure that a newer suburb simply hasn't had time to accumulate, and the dense urban blocks around them add steady rat and cockroach pressure of the kind any river city sees.
The pests you will run into in Gretna
| Pest | When active | Local notes |
|---|---|---|
| Subterranean Termites | Spring through fall | Old Gretna's Creole cottages and shotgun houses, dated between about 1845 and 1935, carry a full century or more of accumulated termite exposure in the humid river soil beneath them. |
| Rats | Year-round, worse in cooler months | Gretna's tightly spaced historic blocks, laid out with narrow lots and alleys dating back to its 1836 founding, give rats connected shelter along the levee and building foundations. |
| Cockroaches | Year-round | Older commercial buildings near downtown Gretna see steady cockroach pressure tied to food service and the humidity typical of the whole river corridor. |
| Mosquitoes | Late spring through fall | Low ground just behind the Mississippi River levee can hold standing water after heavy rain, giving mosquitoes a breeding source near Gretna's oldest residential blocks. |

Or call 1-800-PEST-USAWhy does Old Gretna's building age drive termite risk?
Old Gretna's 737 buildings, more than 550 of them counted as historic contributing structures, went up in waves between about 1845 and 1935, and a Creole cottage or shotgun house from that era has had a full century or more to accumulate subterranean termite exposure in the humid Mississippi River soil beneath it. That's a longer exposure window than most Jefferson Parish housing carries, and it's the main reason a termite inspection matters more for a Gretna property inside the historic district than for a comparable home in a newer part of the parish.
Does Gretna's density along the river add to rat and cockroach pressure?
Gretna's historic blocks were laid out tightly, with narrow lots, shared walls, and alleys that go back to its 1836 founding as a rail and ferry crossing to New Orleans, and that density gives rats and cockroaches more connected shelter and food access than a spread-out suburban block would. Older commercial buildings near downtown see the most consistent cockroach pressure, tied to food service and the same humid climate that runs through the rest of the river corridor, while rats move along the levee, drainage lines, and building foundations that connect Gretna's oldest blocks.
How does the Mississippi River levee affect mosquito exposure in Gretna?
The grassy levee that runs along the river through Gretna keeps floodwater out, but the low ground just behind it can still hold standing water after a heavy Gulf South rain, and that gives mosquitoes a breeding source close to some of the town's oldest residential blocks. Combined with the humidity typical of the whole New Orleans metro area through late spring and summer, properties near the levee or in low-lying parts of the historic district generally need more consistent mosquito control than blocks on higher ground further from the river.
Prevention steps for Gretna homes
- ▪Schedule a termite inspection for any property inside or near the Old Gretna historic district given its 1845 to 1935 building ages.
- ▪Keep a recurring cockroach service in place for older commercial buildings near downtown Gretna.
- ▪Seal foundation gaps and shared-wall entry points common to Gretna's tightly spaced historic lots to limit rat access.
- ▪Clear standing water in low-lying areas behind the levee through the summer mosquito season.
- ▪Address moisture damage in older wood-frame construction promptly to avoid attracting termites and carpenter ants alike.
What you will pay in Gretna
Termite inspections for Old Gretna's historic district homes typically run $150 to $300 given the building ages involved. Recurring cockroach service for older commercial buildings is often billed monthly. Free inspection included.
Gretna pest control questions
Why does Old Gretna need more termite attention than newer Jefferson Parish neighborhoods?
Old Gretna's buildings date from about 1845 to 1935, giving them a century or more of accumulated subterranean termite exposure in the humid river soil, a longer window than most newer Jefferson Parish housing carries.
Are rats a bigger issue in Gretna's historic district than elsewhere in town?
Gretna's oldest blocks, laid out with narrow lots and alleys dating to its 1836 founding, give rats more connected shelter along the levee and building foundations than a spread-out suburban block would.
Does the Mississippi River levee change mosquito risk in Gretna?
Yes. The low ground just behind Gretna's levee can hold standing water after heavy rain, and combined with the metro area's humidity that gives properties near the levee more consistent mosquito pressure than blocks on higher ground.
