Nesting from late winter into midsummer, often more than one brood, with mite complaints following each one
The noise is what people call about. The blocked duct is the reason to act quickly. Starlings and house sparrows pack coarse grass and pine straw into dryer vents, bathroom fan ducts and gable vents, and a plugged exhaust run means an appliance that cannot vent, lint collecting against a hot duct and a fire risk sitting inside a wall where nobody can see it.
Most people call after noticing one of these.
An exhaust that cannot discharge sends heat and moisture back into the drum and the laundry room. A load that used to take one cycle and now takes two, with a hot damp smell in the room, is the earliest practical warning and it usually arrives before anybody hears a bird.
Nest material visible at the opening is the tail end of something much larger down the duct. What you can see and pull out is generally a fraction of what is packed behind it.
Movement in the ceiling directly around the fan housing, loudest in the morning. It means the duct or the roof cap is occupied, and it also means that fan is now venting damp air into a cavity rather than outside.
Material trailing out between the slats shows the screen behind them has failed. A gable vent nest does not create a fire risk, but it does put birds, mites and droppings directly into the attic.
Droppings running down vinyl or brick under an opening confirm it is in daily use and give you the location from the ground without a ladder.
When the young leave, the mites that lived on them do not. They move out through the vent and along the ceiling looking for a host, and a fresh crop of bites appearing the same week the chirping ends is the usual sequence.
Coastal construction hands these birds a row of ready made cavities. Vinyl sided houses across Carolina Forest, Socastee and the beach neighborhoods terminate a dryer duct, a bath fan and a range hood in plastic wall caps with light flappers, and gable ends carry louvered vents that were only ever backed with insect screen. Salt air then corrodes the springs, screws and staples holding all of it together, so within a few years a flapper stops closing properly and a screen lets go at one corner.
The birds themselves are the two that thrive around people, and the Grand Strand supplies plenty of that. Starlings and house sparrows work shopping plazas, restaurant service areas, rental blocks and anywhere food and hard surfaces meet. The nesting season here is long and mild, so a pair can raise more than one brood between late winter and midsummer, and a warm dryer duct is an attractive proposition in February. Which is why the first nest of the year often goes in before anybody is thinking about birds at all.
Conway's downtown and riverfront homes still lean on soffit vents and old dryer exhaust runs that never got capped, and starlings work those openings the same way house sparrows do near the golf communities outside Longs, along the SC-9 and SC-905 corridor where new construction backs up to open woodland. Even out toward the Waccamaw River, the pattern holds: any warm, dark vent is a nest site waiting on the right week in February.
Roofline gaps and dryer vents draw the same attention whether the house sits in Conway or well outside it. Older bungalows near the Waccamaw River aren't unique in that regard: the pros we connect you with field identical vent-nesting calls out toward Forestbrook, along US-17 Business near Surfside Beach, and even up by North Myrtle Beach, wherever a warm, dark opening sits unscreened through late winter.
Calls for it come in from all over Horry County, Myrtle Beach, Carolina Forest and Socastee among them.
Chimney swifts and native cavity nesters. This distinction is the one with legal consequences, so it comes before anything is pulled out of a duct. Chimney swifts occupy masonry flues rather than metal ducts, cling vertically to the wall inside, produce a rolling mechanical twitter, and build a small half cup of twigs glued to the brick instead of a bulky mass. Carolina wrens and house finches also nest in and around vent hoods and porch fixtures, and both are native and protected. A starling squabbles noisily at the opening in broad daylight and jams the duct solid with straw; a sparrow does the same on a smaller scale. If nobody can say with confidence which of these is in there, the answer is to look properly, not to guess and start pulling.
Identification comes first because the law turns on it, and so does the schedule. Somebody establishes which species is in there and whether the nest is active, holding eggs or young, using a camera down the duct or at the hood rather than by feel. If it is a native species with an active nest, the work waits until the young have fledged, and in the meantime the appliance on that duct is taken out of service, which for a dryer is not a suggestion. Where it is a starling or a house sparrow the removal can proceed, and it means clearing the full run from the hood back along the duct rather than pulling out the handful of straw within arm's reach, because the compacted plug further in is what holds the lint.
Then the opening gets rebuilt, since a cleared duct with the same broken cap on it refills the following spring. A dryer terminates in a proper metal hood with a damper that actually closes, and it stays free of mesh, because a screen across a dryer exhaust collects lint and creates the blockage you were trying to prevent. Crushed foil flex duct inside the wall is replaced with smooth wall pipe so lint has nothing to catch on, and the run gets cleaned end to end. Bath fan and range hood terminations get their own working dampers, gable louvers are backed with stainless or galvanized mesh rather than insect screen, roof caps are screened where the fan design allows it, and any soffit gap that let a bird into the attic is closed. The mite and droppings cleanup is done at the same visit, with the material bagged rather than swept into the room.
Whether birds in vents and ducts 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.

Species identification decides what is lawful here, and the position is well documented. The US Fish and Wildlife Service states that the Migratory Bird Treaty Act does not protect introduced species including the house sparrow, the European starling, the rock pigeon and the Eurasian collared dove, and those are the birds vent work is normally aimed at, so their nests can be removed. Native birds are a different matter entirely. Carolina wrens, house finches, chimney swifts and the rest are federally protected, and a nest with eggs or chicks in it is not something to pull on a hunch about which bird put it there. In practice that means somebody looks first, names the bird, says whether there are eggs or young, and then either clears it or books the work for after fledging. If a duct has to stay blocked in the meantime, stop using that appliance, and have the run cleaned and inspected before it goes back into service.
The expensive part of this is almost never the bird. A dryer duct plugged with nest material stops the appliance discharging, so heat, moisture and lint build up in the run, and lint against a hot duct is what fire agencies point to as the cause of dryer fires rather than anything exotic. Even where nothing ignites, the appliance works harder and fails earlier and the run may be scorched or deformed by the time anybody looks. A bathroom fan whose duct is blocked pushes damp air into a wall or ceiling cavity instead of outdoors, and in this humidity that shows up as a stained ceiling, peeling paint and eventually a mold question, which is a drywall repair rather than a vent clean. Then the smaller items that still add up: a broken hood and damper to replace, crushed flex duct swapped for smooth wall pipe, gable louvers rescreened, nest debris and droppings removed from a duct or an attic, a mite treatment in the room below, and occasionally an appliance service call for a dryer that has been overheating for months.
Clearing the visible end of a dryer vent and checking that the flapper closes freely are reasonable homeowner jobs, and so is pulling the lint trap and vacuuming the housing behind it, which is worth doing seasonally whether or not a bird ever visits. Backing a gable louver with galvanized mesh from the inside is straightforward if you can move about the attic safely. Three things to leave alone. Do not put screen or hardware cloth over a dryer exhaust. Do not pull a nest you have not identified, since disturbing an active nest of a native species is a federal matter rather than a judgment call. And do not keep running a dryer on a duct you suspect is blocked while you get around to it, because that is precisely the window in which these things go wrong.
There are two ordinary issues and neither should be dramatized. The first is mites. Nest mites and bird lice live on the young and disperse once the brood leaves, moving out through the duct and into the room, where they bite people around the ankles and the waist and are almost impossible to find. They cannot complete a life cycle on a person, so the problem resolves once the nest and debris are gone and the area is treated, but it accounts for the week of unexplained bites that so often follows the chirping stopping. The second is the nest material itself, which holds droppings, feathers and feather dust, so it is handled with gloves and a mask and bagged rather than shaken out over the laundry room floor. Large accumulations of droppings in a confined space such as an attic warrant more care again, and a bathroom fan that has been venting into a wall cavity instead of outside brings its own damp and mold question that is worth checking while the duct is open.
Birds in Vents and Ducts normally comes in somewhere from an estimated $189 to $499, with access under the floor moving it as much as anything. Nobody charges you for the looking, and the figure is written down before a technician starts. Every band, and what pushes it up, sits on the pricing guide, and the service covering it is Wildlife Removal.
Hands, not teeth. A raccoon does not chew its way in, it takes something apart.
The calendar decides this one. Bat work here is governed by a calendar before anything else.
The animal behind most attic calls. Nearly every attic call in Horry County turns out to be this animal.
Treat it as this week rather than this month, and stop using the dryer in the meantime. The concern is not the birds, it is that a blocked exhaust traps heat, moisture and lint inside a duct that runs through a wall, and lint accumulating in a hot duct is the recognized cause of dryer fires. Everything else on this page can wait for a convenient appointment. That one cannot, and the interim measure is free: use a laundromat for a few days rather than running a load through a duct that has grass in it.
If it is a starling or a house sparrow and there are no young in it, yes, and the whole run should be cleared while somebody is there. If there are eggs or chicks and the species is native, no, because that is federally protected and the work is scheduled for after the young have fledged. The order therefore matters: identify, then decide. Pulling a nest without knowing what put it there is how a routine vent job turns into a genuine problem.
Very often, and the timing is the clue. Mites that lived on the chicks leave once the brood does, come out through the duct or the ceiling and bite whoever is nearest, usually around the ankles. They are too small to spot easily and they cannot live on people, so the fix is removing the nest and debris, treating the area around the duct and the room below, and vacuuming thoroughly. Bites that started the same week the chirping stopped are almost always this rather than fleas or bed bugs.
Through the same opening, yes, and that is the part homeowners tend to skip. These birds return to a proven cavity, and a cleared duct behind a cap whose flapper no longer closes is still a proven cavity. The work that ends it is the hardware: a metal hood with a damper that shuts, smooth wall duct inside the wall, working dampers on the bath fan and range hood, and galvanized or stainless mesh behind gable louvers. Clean the duct and leave the cap broken and you have bought yourself twelve months.
One free inspection settles what it is and how far it has traveled. The estimate lands in writing before a technician starts.
