Anyone in Myrtle Beach dealing with mice or rats, or hoping to keep them out.
What to look for
Seeing one in daylight usually means there are more. A mouse fits through a gap the size of a dime. You hear them at night and find droppings by morning. Rodents are mostly unseen.
- 1Tracks or tail drag marks in dust or flour.
- 2Bait or pet food vanishing from bowls overnight.
- 3Rodent hair or droppings inside HVAC ducts.
- 4Pipe gaps stuffed with debris or looking chewed wider.
- 5Shredded paper, fabric, or insulation gathered into a nest.
- 6A musky or ammonia-like smell in closed rooms.
Why it’s worth acting soon
- Mice breed fast, every few weeks.
- Droppings and urine contaminate food and insulation.
- Gnawed wiring can be a fire risk.
- Nests and odor get harder to clean the longer they stay.
Treatment options and typical costs
Inspection and Entry-Point Mapping
$75–$250
The inspection identifies the species and how bad it is. Droppings, grease trails, and nest material in Myrtle Beach attics and crawlspaces show how long they have been there.
- Time
- 60–90 minutes
- Best for
- Every job; nothing else works without it
Sealing and Rodent-Proofing
$200–$1,500, more for large or complex homes
Rodent-proofing means closing every gap a rodent can use with metal. Around Myrtle Beach, that usually means copper or stainless mesh in pipe gaps, sealed foundation vents, and fresh door sweeps.
- Time
- 2–6 hours, sometimes a full day
- Best for
- Stopping re-entry for good; the lasting fix
Tamper-Resistant Exterior Bait Stations
$100–$300 setup, $40–$80 per service visit
Bait stations belong outside, not in the attic. A Myrtle Beach pro places them along fence lines, near sheds, and beside foundations where rats travel, then services them monthly or quarterly.
- Time
- 30–45 minutes per visit, ongoing
- Best for
- Outdoor rat pressure; ongoing perimeter protection
Snap-Trap Program
$150–$400 per visit
Trapping works best alongside sealing. Alone, it only lowers the count. After sealing, the last traps confirm the house is clear.

Crawl spaces are where rats and mice get comfortable. Vent screens, the sill plate and any gap around pipes are worth a careful look.Which rodents live around Myrtle Beach.
They climb, and come in high through attic vents and branches. Roof rats are common around Myrtle Beach too. They burrow along foundations and enter low. Norway rats are the other usual suspect. They're small, curious and breed quickly. House mice are the most common rodent in Myrtle Beach homes.
When they move in.
Small problems grow fast. Spring is breeding season. Listen for them in the attic after dark. Roof rats are active all year. Check for gaps before then.
A metal vent cover with a working flap keeps mice out all winter. Plastic flaps crack in the cold and get chewed open.How they get into houses here.
Trim branches back from the roof. For roof rats, check soffit vents, gable vents and eaves. Look for gaps where pipes and wires pass through the floor. Make sure the crawl door closes tight. Check that vent screens are intact. A lot of houses around Myrtle Beach have crawl spaces, and crawl vents and access doors are the usual way in.
A year of rodents in Myrtle Beach.
- Fall: rodents look for shelter. Seal gaps before cold nights arrive. - Summer: with highs around 89°F in Myrtle Beach, rodents look for water. Fix drips and leaks. - Spring: breeding season. Act on any sign quickly. - Winter: with lows near 38°F in Myrtle Beach, check the attic, garage and pantry for droppings.
Mice or rats?
- Droppings: mouse droppings are rice-sized. Rat droppings are two or three times bigger. - Rub marks: rats leave greasy smudges along walls and beams. - Behavior: mice are curious about new traps. Rats avoid them for days. - Sounds: mice sound light and quick. Rats sound heavier. - Holes: mice chew dime-sized holes. Rats chew holes closer to quarter-sized.
Sealing small gaps yourself.
- Steel wool or copper mesh: pack it into small gaps first. - Check your work: daylight through a gap means it isn’t sealed. - Expanding foam: fine on top of mesh, useless on its own. - Door sweeps: close the gap under garage and exterior doors. - Hardware cloth: use quarter-inch mesh over vents and larger holes. - Sealant or mortar: cover the mesh so it stays put.
Cleaning up droppings safely.
- Air the room out for 30 minutes first. - Wash your gloved hands, then your hands. - Don’t sweep or vacuum droppings dry. It stirs up dust. - Wipe up with paper towels and bag them. - Spray droppings with a bleach solution, then wait five minutes. - Wear rubber or plastic gloves.
What happens at an inspection.
Most inspections take about an hour. Photos help. You should come away with a list of entry points. They'll also check the crawl space. Inside, they check the kitchen, garage and attic. They check the foundation, vents, rooflines and utility gaps. The inspector walks the outside first.
Rodents in the car.
Park in a closed garage when you can. Mice and rats nest in engine bays and chew wiring. Clear birdseed and pet food from the garage. Check the air filter box for nesting.
Bird feeders and rodents.
Use a seed tray and sweep up spills. Spilled seed feeds mice and rats. Store seed in a metal can with a tight lid. If rodents show up, bring feeders in at night.
Questions to ask before you sign.
- Where are they getting in? - Will you use poison inside? (Ask them not to.) - Is cleanup included, or extra? - What happens if they come back? - How many trap visits are included? - Which gaps will you seal, and with what?
Rodents by the numbers.
Around Myrtle Beach, ask any provider to show you the entry points and the plan before you compare numbers. Around Myrtle Beach, those three findings — species, entry points, and scale — are what a quote should be built on, not a regional average. Around Myrtle Beach, what actually matters is a walk-through: where the droppings are, how the rodents are getting in, and how large the colony is. National surveys set rough expectations but cannot diagnose one house.
What affects the price
- Home size, stories, and roofline complexity.
- Local labor rates and licensing costs.
- Follow-up visits included versus billed separately.
- Crawlspace or slab; crawlspaces add labor.
- Attic access and how much insulation is contaminated.
- Exterior bait stations and ongoing service frequency.

What's your biggest concern about rodents?
When to call for help
Call right away if you see rats. They take a longer, more careful approach. Attic cleanup is hard to do safely without training. Call if you hear them in the attic or walls. Droppings in several rooms are another sign. So is a dead-rodent smell.
What you can do yourself
Start tonight with snap traps along the walls. Bait them with peanut butter. Store food in sealed bins. Seal small gaps with steel wool and sealant. Rooflines, vents and attics are harder. That's where a pro's sealing work pays off.

On Kiawah Island a Clemson entomologist reported roof rats as the only rodent recorded, with mice largely absent.
Clemson University Cooperative ExtensionRodent species recorded in South Carolina
- House mouse (Mus musculus) — Enters at 1/4 inch; 5-10 litters per year; eats about 200 small meals a night.
- Norway rat (Rattus norvegicus) — Burrowing rat of basements, sewers and ground floors; tail shorter than head plus body.
- Roof rat (Rattus rattus) — Climber of attics and trees in warm and coastal regions; tail longer than head plus body.
When rodents are busiest around Myrtle Beach
Year-round; fall peak. Pacific Northwest: roof and Norway rats plus deer mice statewide in Washington.
Based on Myrtle Beach’s humid subtropical climate profile.
South Carolina is one of the few states with a statewide second-generation anticoagulant restriction, so coastal roof rat work leans on exclusion and trapping.

Simple ways to keep rodents away
- Walk the exterior each season looking for fresh gnawing.
- Store pet food and birdseed in sealed metal containers.
- Take bird feeders down or use catch trays for spilled seed.
- Keep ivy, shrubs, and firewood away from the foundation.
- Cover dryer and exhaust vents with metal louvered covers.
- Inspect vehicle engine bays if parked near fields or woods.
A good rodent quote lists the inspection, the number of trapping visits, each opening to be sealed and the material for it, and any cleanup.Did you know?
Male house mice sing ultrasonic songs that humans can't hear.
Around Myrtle Beach, a rodent's front teeth never stop growing, so it gnaws constantly to keep them worn down.
Questions people ask
Will rodents leave on their own?
Rarely. Once they've found food, water and a warm nest, they stay.
What should be in a rodent control quote?
It should say what happens if they return. Cleanup should be listed separately. Entry points, sealing materials and the number of trap visits.
How do I choose a rodent control company?
Ask what happens if rodents come back. A good company talks about sealing, not just traps. Make sure they're licensed in South Carolina. Ask how they seal gaps and what materials they use.
Do ultrasonic repellers work?
It doesn't pass through walls either. Sealing and trapping work better. Not reliably. Rodents get used to the sound within days.
Are rats a bigger problem than mice?
Rats are bigger, chew more, and avoid new traps for days. Around Myrtle Beach, roof rats often nest in attics, so check the roofline too. Usually.
