Most people call about pests twice: once when something crawls across the kitchen floor at midnight, and again a few months later when it happens again. The gap between those two calls is really the whole question behind choosing a one-time pest treatment or a quarterly pest control service. One of them ends an episode. The other is built around the fact that in St. Bernard Parish, episodes don't stay ended on their own.
A one-time pest treatment makes sense when you can point at a cause. You brought in firewood or cardboard boxes and now you have something you didn't have last week. A neighbour's slab got torn up and the roaches moved next door. You're closing on a house in Arabi and want it cleared before the furniture goes in. The work is a full interior and exterior treatment: baiting and crack-and-crevice applications where roaches actually live — under the sink, behind the dishwasher motor, in the void around plumbing penetrations — and a perimeter band outside with attention to the weep holes, door thresholds, A/C line entries and anywhere the slab meets siding. Done properly it takes a couple of hours and includes finding the way in, not just killing what's already inside.
What a one-time visit can't do is hold a line. The Gulf Coast gives pests three good breeding seasons and a fourth that's only slightly less good. American roaches live in the sewer and storm drain system and come up through floor drains and under doors whenever it rains hard. Rodents move indoors every cool snap. A single treatment leaves residual product that breaks down in sun and rain over a matter of weeks, not years, and once it's gone the pressure from outside is exactly what it was.
Quarterly pest control service is a perimeter maintained year-round, with each visit timed to what's happening outside. The spring service goes heavier on ants and the first roach pressure. Summer is peak activity and usually the visit where mosquito harbourage and fire ant mounds in the yard get attention. Fall is when rodents start testing the building, so that visit leans toward exclusion — checking the garage door seal, soffit gaps, and gaps where utilities enter. Winter is the quiet one and the best time to deal with anything overwintering in a wall void or attic.
Between visits, any pest covered by the plan should be handled without an extra charge. That matters more than the treatment itself. A good quarterly plan is really a relationship where somebody who knows your house comes back and adjusts, rather than applying the same product to the same spots four times a year.
Not every pest is the same job, which is where plans go wrong if nobody explains it. Fire ants are an outdoor, yard-wide problem treated with broadcast bait and mound work, and they come back from neighbouring property, so they're a managed thing rather than a solved thing. Carpenter ants mean moisture and damaged wood somewhere — a leaking window header, a wet sill — and treating the trail without finding the wet wood just moves them. German roaches in a kitchen are a sanitation and harbourage problem needing follow-up visits a couple of weeks apart; American roaches coming in from the drains are an exclusion problem. And general pest plans in this area do not cover termites. Formosan subterranean termites have been established in the New Orleans area since the 1950s, they're the most destructive termite we have, and the USDA has put the city's control and repair bill at roughly $300 million a year. Termite protection is a separate contract with its own inspection and its own warranty — ask directly, because assuming you're covered is how people lose a wall.
Ask what pests the plan covers and which ones it excludes. Ask whether re-treatments between quarterly visits are included. Ask what the product is and what you need to do about pets, fish tanks and children for the next few hours. Ask whether the technician will be inspecting for entry points or only spraying. And ask what happens to the agreement if you sell the house.
