Mosquito Prevention & Control
Fight the Bite and Help Reduce the Risk of Mosquito-Borne Illness
Mosquito control is a shared responsibility. Local programs monitor mosquito activity, manage control efforts, and provide education and tools to help residents reduce risk. Understanding mosquitoes and how control efforts work can help residents take simple, effective steps to protect themselves and their community. One proven approach is the 3 D’s of Mosquito Protection: Drain standing water, Dress in long sleeves and pants, and Defend with EPA-registered repellent.
Safety Tips During Vector Control Operations
Along with personal prevention steps, residents are encouraged to follow these safety tips when vector control operations are underway:
- Do not follow or pass trucks actively conducting mosquito control spraying.
- Watch for posted notices announcing spray schedules and treatment areas.
- Ensure apiaries are registered with NC BeeCheck.
Residents may choose to stay indoors and close windows during spraying, though this is not required. Treatments are not harmful to pets, but owners may bring animals indoors if preferred.
Reduce Your Risk & Protect Yourself From Bites
Residents can reduce mosquito activity and lower risk by following the 3 D’s: Drain, Dress, and Defend.
Drain
Remove standing water where mosquitoes breed.
- Empty and scrub items that hold water at least twice a week.
- Drain tarps and covers, clean gutters, and fix leaks.
- Cover rain barrels, maintain pools, and fill low spots in yards.
Dress
Wear clothing that helps reduce bites.
- Choose light-colored, loose-fitting clothing.
- Cover skin with long sleeves, pants, socks, and closed shoes.
- Use permethrin-treated clothing for added protection (do not apply to skin).
Defend
Use repellents and barriers to avoid bites. Follow repellent labels carefully. Repellents can be used on children 2 months and older and during pregnancy when used as directed.

- Use EPA-registered repellents with DEET, picaridin, IR3535, or oil of lemon eucalyptus (PMD).
- Avoid peak mosquito hours at dawn and dusk when possible.
- Use fans or mosquito nets in outdoor spaces.
Understanding Mosquito-Borne Virus Risks
Mosquitoes in eastern North Carolina can spread mosquito-borne viruses that affect people and animals. In Pitt County, the primary concerns are West Nile Virus (WNV) and Eastern Equine Encephalitis (EEE). Taking simple prevention steps helps reduce risk, especially during warmer months.
West Nile Virus (WNV)
WNV is common in North Carolina. Most people have no symptoms, but some may develop mild illness. Severe cases are uncommon and more likely in older adults or those with weakened immune systems.

EEE is rare but serious and can cause severe neurological illness. Horses are especially at risk, and annual vaccination is strongly recommended.

Mosquitoes also spread heartworm disease in dogs and cats. Year-round prevention and routine testing are recommended.

While there are no human vaccines for mosquito-borne viruses, vaccines are available for horses to protect against WNV and EEE. Annual vaccination is recommended in Pitt County.
Knowledge Is the First Line of Defense
Mosquitoes have been around since the Triassic Period—over 400 million years ago? Also some studies have shown mosquito activity can increase by up to 500% during a full moon, and that movement may boost biting by as much as 50%?

Mosquitoes are insects in the Diptera group, meaning “two wings.” One of the most common nuisance species in Pitt County is the Asian tiger mosquito (Aedes albopictus), known for its black-and-white stripes and aggressive biting.
Habitat
Mosquitoes thrive in warm, wet areas. The Asian tiger mosquito is especially common in neighborhoods and can breed in very small amounts of standing water. Common breeding sites include:
- Clogged gutters
- Flowerpots and plant saucers
- Uncovered trash bins
- Bird baths and pet bowls
- Old tires and discarded containers
- Any item holding water for more than a few days
Life Cycle of the Mosquito
Mosquitoes develop through four stages: egg, larva, pupa, and adult. In warm weather, this cycle can be completed in as little as 7 to 10 days.
- Eggs: Females lay eggs after a blood meal. Eggs are placed in or near water and can survive dry conditions until flooded.
- Larva: Larvae live in water and cannot survive if the water dries up.
- Pupa: This short stage lasts one to two days. Pupae do not feed but remain active in water.
- Adult: Adult mosquitoes emerge ready to mate. Females bite to produce eggs and may lay hundreds over their lifetime.
Tools and Treatments Used to Reduce Mosquito Activity
Along with public education, Pitt County Environmental Health uses a layered mosquito control approach that includes source reduction, larviciding, and adulticiding. Clearly marked vector control trucks and routine surveillance help guide when and where treatments are used.
Staff use tools such as landing counts and mosquito traps to measure activity levels and select the most effective control method for current conditions.
Source Reduction
Source reduction focuses on removing standing water where mosquitoes breed. Staff can evaluate properties upon request and often find that small containers are the main cause of mosquito issues. Eliminating these sites is the most effective way to reduce Asian tiger mosquitoes.Larviciding
Larviciding targets mosquitoes before they become adults. Biological products are applied to known breeding areas identified through surveillance and routine monitoring.Adulticiding
Adulticiding uses Ultra Low Volume (ULV) spraying to reduce adult mosquitoes and is used only when needed. Decisions are based on landing counts and trap data, including species identification, to determine whether spraying is appropriate.
Help Protect Pollinators
Beekeepers in Pitt County are encouraged to register hives with the NC BeeCheck Program. This free, voluntary tool helps reduce the risk of pesticide exposure during vector control.
Visit the NC BeeCheck Program.
What Is BeeCheck?
BeeCheck is a secure, online mapping service that lets beekeepers mark hive locations. Licensed applicators and mosquito control programs can view this information before spraying, helping protect bees and other pollinators.
Why Register?
- Reduce risk to pollinators during mosquito control operations.
- Help applicators avoid hive locations when planning treatments.
- Support responsible pesticide use and environmental stewardship.
How to Register
Registration is quick and free:
- Sign Up on NC BeeCheck Now
- Create a profile and add hive locations.
- Update locations each season.
Registering hives helps balance mosquito control efforts with pollinator protection across Pitt County.
