Roaches falling from a soffit
One dropping onto a doorstep or a deck as you pass under the eave puts the harborage in the soffit or the gutter directly above. It is worth looking up before anything gets sprayed at ground level.

Smokybrown Cockroaches and the Roof Line Route in Conway, SC
Warm months, peaking in the humid stretch from June into September
The short version
This is the other palmetto bug, and it has a completely different address. Smokybrown cockroaches lose body moisture quickly, so they shelter in tree holes, leaf packed gutters, soffits and attics rather than drains. They fly well and they enter high, which means the diagnosis usually happens on a ladder rather than in a kitchen.
Diagnosis
What you will notice first
Most people call after noticing one of these.
Gutters holding a wet leaf mat
A packed gutter is a warm, permanently damp channel running right along the roof edge, which is close to ideal for a species that cannot tolerate dry air. Clearing it removes the harborage rather than just the mess.
Shed skins in the attic
Pale, empty casings caught in insulation or along a rafter show they are living up there and molting, not just passing through on a warm night.
Sightings on upstairs windows
A roach on a second floor windowsill has almost certainly arrived by air or by way of the roof, so the entry point is a gable vent, a soffit gap, a chimney chase or an attic penetration rather than a doorway.
Why this one turns up here
Conway has the tree canopy this roach needs. Live oaks, water oaks and pines around the older streets near the riverfront drop leaves into gutters all year, and every one of those clogged runs becomes a damp harborage at roof height. Cabbage palmetto and palm boots in newer landscaping do the same job lower down. Because it dries out fast and cannot survive a dry indoor space for long, it stays in these permanently humid pockets and moves toward the building rather than living inside it.
The humidity that defines this coast is what makes the roof line so attractive. Warm nights, heavy summer thunderstorms and dew that lingers into mid morning keep gutters, fascia and shaded soffits damp for weeks at a stretch. Overhanging limbs then act as a bridge that skips the perimeter entirely, so all the sealing at ground level in the world does nothing about a colony arriving from a branch three feet above the roof. Attic humidity finishes the picture by giving them somewhere to settle.
Conway's older neighborhoods carry mature oak and pecan canopy right up against roof lines, which is exactly the bridge that lets smokybrown colonies skip a sealed foundation entirely. The same pattern shows up on jobs the licensed pros we connect you with run out toward Aynor, where farmhouse tree lines sit close to older roofs, and up US-501 into that surrounding farmland. Loris properties with heavy tree cover see it too, since a roof line route doesn't care how far it is from the coast.
We deal with this across Conway and the surrounding towns, Socastee, Surfside Beach and North Myrtle Beach included.

What it gets mistaken for
American cockroaches. One even color is the whole test. A smokybrown has no pale outline and no figure eight behind the head, so the shield and the wings read as a single dark mahogany. An American cockroach shows a light yellowish border on that shield. Behavior separates them too: a smokybrown flies purposefully and turns up at an upstairs window or in the attic, while an American is more often found on a floor near a drain or a vent at ground level.
The treatment, step by step
The inspection goes up. That means gutters and downspouts, fascia and drip edge, soffit joints and vents, gable and ridge vents, the chimney chase, any tree limb within reach of the roof, palm boots and dead fronds, plus stacked firewood and stored lumber against a wall. In the attic the questions are humidity, whether the ventilation is actually working, whether there are shed skins or droppings, and where light shows through a joint. This roach is a symptom of a wet roof edge, and that is the report the homeowner needs.
Treatment then matches the height it was found at. Bait and dust placements go into soffit voids, the attic perimeter and wall voids rather than being sprayed across open surfaces, with a targeted exterior treatment at the fascia, eave line and any tree contact. The lasting part of the work is mechanical: gutters cleared and guarded, limbs cut back off the roof, soffit and vent gaps screened, and attic ventilation put right so the space stops holding moisture. Where a house is under trees on all sides, seasonal follow up through the warm months keeps the roof edge from rebuilding a colony.
Whether smokybrown cockroaches wants ongoing cover comes down to the cause. Fix a route in and it is a job. Leave a damp crawl space and it is a season.

What is genuinely worth doing yourself
Gutter cleaning is genuinely the highest value hour anyone can spend on this problem, followed by cutting branches back so nothing touches or overhangs the roof. Moving firewood off the wall, clearing dead palm fronds and boots, and getting a bathroom fan to vent outside rather than into the attic all help. What does not work is spraying a baseboard indoors, because the insect you saw came from above and the population never touches that surface. Ladder work on a two story roof edge, soffit voids and anything involving attic ventilation are also the points where most homeowners are better off handing it over.
The health side, honestly
Milder than the kitchen roach but not nothing. Droppings and shed skins accumulate in attic insulation and soffit voids and become part of the dust that moves through the house whenever the air handler runs or someone opens a hatch, which matters in a household with asthma. They also feed on decaying organic matter in gutters and leaf litter before entering, so anything they walk over indoors is worth wiping. Wear a mask and gloves when clearing droppings or insulation in an attic and bag the waste rather than sweeping it dry.
What you would be spending
Smokybrown Cockroaches normally comes in somewhere from an estimated $99 to $289, with access under the floor moving it as much as anything. Having somebody look costs nothing, and you see the number in writing first. See the pricing guide for the complete set of ranges, and this one is handled under Cockroach & Palmetto Bug Control.

Questions & Answers
Frequently Asked Questions
How is this different from the palmetto bug I already have?
Chiefly by address. Both get called palmetto bug locally, but the American cockroach lives at ground level in drains, mulch and crawl spaces, while the smokybrown lives high in gutters, tree cavities and attics. That single difference decides where the inspection goes and where product is placed, so identifying which one you caught is not a technicality.
Do I really need to clean the gutters to fix this?
It is the closest thing to a fix there is. A gutter packed with wet leaves is a heated, permanently damp corridor at the exact height these roaches enter, and no treatment will out run a harborage that keeps refilling every autumn. Clearing and guarding the gutters, then cutting limbs back off the roof, does more for the problem than repeated spraying.
Can they breed in my attic?
They can, given moisture. A hot, dry attic with working ventilation is hostile to them, but one with poor airflow, a bathroom fan discharging inside, or a small roof leak holds enough humidity to support them. Shed skins and droppings in the insulation are the sign it has gone from a route to a residence, and it changes the job from perimeter work to attic work.
