Anyone in Apex tired of mosquito bites at home.
What to look for
Often the source is a neighbor's yard or a storm drain. In summer heat, eggs become biting adults in about a week. Mosquitoes breed in standing water, even a bottle cap's worth.

Treatment options and typical costs
Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
Around your Apex home, the inspector also checks where adults rest: dense shrubs, ivy, under the deck and along shady fences. Knowing where adults hide shows where barrier spray matters.
- Time
- 30–60 minutes
- Best for
- Every yard; finds where mosquitoes actually breed
Misting Systems and In2Care-Style Stations
misting $2,000–$4,500 installed plus refills; stations $200–$500 per season
Neither option replaces the basics. A pro should still dump and treat standing water every visit.
- Time
- Misting: half a day. Stations: under an hour.
- Best for
- Specific yards: heavy outdoor use or spray-averse owners
Monitoring and Seasonal Plans
$50–$150 per follow-up visit; $350–$900 per season bundled
Between visits in Apex, a good pro uses traps or landing counts to check the treatment is still working. Numbers climbing early means a missed breeding site.
- Time
- 15–30 minutes per check; season runs spring through first frost
- Best for
- Anyone who wants the yard usable all summer
Source Reduction and Larviciding
$75–$150 per visit
Larvicide hits mosquitoes before they can fly, which is why pros in Apex build every plan around it. Adult spraying is the follow-up, not the fix.
- Time
- 45–90 minutes
- Best for
- Yards with standing water, clogged gutters, ponds, or drains
Prices are typical published ranges. Ask what’s included before you compare quotes.
A treatment visit covers the shaded plants and beds where adults rest, along with any standing water that can't be drained.How mosquito treatment works in Apex.
First, find and remove the water where they breed. Then spray where the adults rest. Across Apex, the season runs from about April through October, so a plan usually starts in spring and runs to the end of the season. Larvicide handles water you can't drain, like ponds or drains. Barrier spray covers shady shrubs and leaves. Treatment has two parts.

A year of mosquitoes in Apex.
- Winter: a good time to fix drainage and low spots. - Spring: the first wave arrives early in Apex. Start treatments then. - Summer: with highs near 89°F in Apex, check water twice a week. - Fall: numbers stay high. Keep gutters clear of leaves.
The weekly water walk.
- Tree holes: fill them with sand. - Gutters: clear leaves so water drains. - Saucers and pots: empty them or add sand. - Toys and buckets: store them upside down. - Tarps and covers: pull them tight so water runs off. - Birdbaths: change the water twice a week. - Pet bowls: refresh daily. - AC drip lines and downspouts: make sure water drains away.
Avoiding bites.
- Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus. - Clothing: long sleeves and pants help at dusk. - Fans: a patio fan keeps weak-flying mosquitoes away. - Screens: repair holes in window and door screens.
Low-cost ways to cut mosquitoes.
- Lights: yellow bug lights attract fewer insects to the porch. - Mosquito dunks: Bti tablets kill larvae in rain barrels and ponds. - Mosquito fish: they eat larvae in ornamental ponds. - Pumps and fountains: moving water breeds far fewer mosquitoes. - Trimming: thin out dense shrubs and tall grass.
Mosquito or look-alike?
- Mosquitoes: slim, long legs, and a needle-like mouth. - Crane flies: look like giant mosquitoes. They don’t bite. - Non-biting midges: swarm near water at dusk. Harmless, just annoying. - No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh.
When a bite needs a doctor.
Most people infected with West Nile virus never feel sick. About one in five get a fever, headache or body aches. See a doctor for high fever, stiff neck or confusion. Spreading swelling or an infected-looking bite needs a check too. Most bites just itch for a few days.
Protecting your pets.
Talk to your vet about year-round prevention. Refresh pet water bowls daily; with about 46 inches of rain a year in Apex, bowls and plant saucers refill themselves. Keep animals inside until a yard treatment dries. Heartworm reaches dogs through mosquito bites, and cats can get it as well; Apex's season runs roughly May into December, so year-round prevention is the usual advice.
What a treatment visit looks like.
The tech walks the yard first. They dump or treat standing water. Larvicide goes in water you can't drain. Then they spray shady shrubs, where adults rest. Most plans repeat every three to four weeks. A visit usually takes 20 to 45 minutes.
Rain barrels and ponds.
- Pool covers: drain standing water after rain. - Barrels: cover openings with fine mesh. - Ponds: fish and moving water keep larvae down. - Bird baths: change the water every few days. - Gutters: clear them so water drains away. - Tarps: shake out any that hold rainwater.
Questions to ask before you sign.
- When can kids and pets go back outside? - What product will you spray? - How often will you come? - Do you treat standing water too? - What happens if bites come back between visits? - How do you protect bees and flowers?
What affects the price
- Synthetic versus botanical barrier products.
- Ponds, creeks, or wetland edges on the property.
- Travel distance from the company's base.
- Lot size and total acreage treated.
- Amount of shade and dense vegetation.
- Number of visits the local season needs.

What's your biggest concern about mosquitoes?
When to call for help
Call if bites still keep you indoors. Dumping water should come first. early in the season, before the first big wave. Ponds, drains and dense shrubs are hard to handle yourself.
What you can do yourself
A pro adds larvicide for water you can't drain. They also spray where adults rest, every few weeks. The biggest win is free: dump standing water every week. Use repellent and run a fan on the patio.
Mosquitoes in Apex
Apex gets about 46 inches of rain a year, so containers and low spots refill constantly through the season. Summer highs around 89°F in Apex speed up the life cycle, and average humidity near 71% keeps adults active. In Apex's neighborhoods, the usual sources are gutters, plant saucers, kids' toys and birdbaths. Apex has a humid subtropical climate, and mosquitoes activity here tends to pick up late spring through early fall; year-round in the deep south. Across Apex, most of the housing is suburban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. Across Apex, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. A local provider who knows Apex and North Carolina can point out the specific conditions that matter most here before you commit to a plan. Across Apex, before you book, ask whether the inspection is included, what the treatment plan covers, how many visits to expect, and what the written quote includes. Across Apex, getting the scope, the prep steps, and any follow-up terms in writing makes it much easier to compare providers fairly, and a good provider will walk you through each of these without pressure.

Questions people ask
What if the mosquitoes are coming from my neighbor's property?
That's common. Treat your own yard and talk to your neighbor. Your local mosquito control district or health department can also help.
Why are there so many mosquitoes in my yard specifically?
Usually there's water nearby, like a clogged gutter or tarp. Shady, damp plants give them a place to rest.
Will mosquito treatment kill bees and butterflies?
It can if spray hits flowers. Ask them to skip blooming plants. Spraying when bees rest helps too.
What are In2Care stations and do they work?
They're small water traps. Mosquitoes visit, then carry larvicide to other water. They work best against container breeders like tiger mosquitoes.
Are misting systems worth it?
For a few homes, yes. They're costly to install and need refills. Most yards do fine with source removal and regular spraying.
Do mosquitoes really change how people use their yards?
Across Apex, mosquito control works by removing standing water, treating the water that cannot be drained, and applying barrier treatments where adults rest. Across Apex, because they keep breeding through the season, an ongoing plan usually works best.
When is mosquito season in Apex?
It runs from about April through October. Daytime biters are tiger mosquitoes; evening biters are usually house mosquitoes.
Do mosquitoes in Apex carry West Nile?
They can. West Nile is found in every lower-48 state, North Carolina included. Cases usually peak in late summer. Repellent and dumping standing water are your best protection.
