Mosquito Control in Charleston, SC

Mosquito Barrier Treatments are designed to protect for about 3 to 4 weeks. Factors like heavy rain or extreme heat can affect this, which is why we schedule visits every month from March through November to ensure your protection never gaps.

Yes. Palmetto uses eco-friendly, biodegradable products and applies them carefully around your property. Once treatments dry, it's okay for your pets and family to enjoy your outdoor space.

We care about our local pollinators! Our technicians are trained to avoid spraying flowering plants where bees and butterflies spend their time. We focus our treatments on shaded areas, shrubs, and tall grass where mosquitoes specifically go to rest and hide from the sun.

Do-it-yourself methods don't normally address the source. Palmetto Exterminators addresses mosquitoes at all life stages, including larviciding, barrier applications, and preventative measures.

1. Asian Tiger Mosquito (Aedes albopictus)

• Where They're Found: Originally native to Southeast Asia, this species is now widespread across the globe, including large parts of the United States, Southern Europe, parts of Africa, and Central/South America. They are aggressive "container-breeders," meaning they thrive in urban and suburban yards rather than large swamps. You will find them resting in tall grass, shrubbery, and dense vegetation, while laying eggs in small, stagnant water sources like flower pots, bird baths, clogged gutters, and discarded tires.
• When They Are Most Active: Unlike many other mosquitoes that only bite at dawn and dusk, the Asian Tiger Mosquito is a daytime biter, with peak biting activity occurring in the early morning and late afternoon. They are active from spring through late fall in temperate climates, and year-round in warmer tropical and subtropical regions.

2. Southern House Mosquito (Culex quinquefasciatus)

• Where They're Found: This species is prevalent in tropical, subtropical, and mild temperate regions worldwide (in the U.S., they are particularly common across the Southern states, Hawaii, and parts of the West Coast). They are heavily urbanized and prefer polluted or stagnant water sources with high organic content—such as storm drains, septic tanks, dirty gutters, and ornamental ponds. They frequently enter homes and rest in cool, dark indoor areas like garages, closets, and under furniture.
• When They Are Most Active: They are nocturnal (night-time) and crepuscular feeders, preferring to bite from dusk through dawn. While they are active during the warmer months in temperate zones, they can remain active year-round in warmer climates.

3. Salt Marsh Mosquito (Oedes sollicitans / Aedes taeniorhynchus)

• Where They're Found: True to their name, these mosquitoes are primarily found in coastal regions, particularly along the Atlantic and Gulf coasts of the United States, as well as parts of the Caribbean. Their larvae develop in coastal salt marshes, tidal pools, and brackish water. However, they are famously strong flyers and can travel several miles inland from their breeding grounds, frequently invading coastal neighborhoods and recreational areas.
• When They Are Most Active: Salt marsh mosquitoes are aggressive biters that will attack both during the day (especially on cloudy days or in shaded areas) and into the evening. They are most active from late spring through the summer and early fall, particularly following high tides, heavy coastal rains, or storm surges that flood their marshland habitats.

The Pros: Why Coastal Homeowners Consider Them

• True Automation: They run on a fixed schedule (typically cycling 2 to 3 times a day at dawn and dusk) without requiring you to remember anything or schedule visits.
• On-Demand Control: Most modern systems come with a remote or app trigger, allowing you to give the yard an extra misting cycle 30 minutes before hosting an evening cookout.
• High-Pressure Relief: In marsh-adjacent or heavily wooded coastal areas where mosquito pressure is fierce, daily automated cycles help keep numbers down in your immediate outdoor living spaces.

They are worth it if you have a property heavily impacted by constant mosquito swarms, and you want a permanent fixture that provides daily, automatic coverage without managing service appointments.
