Mosquito exterminator: what they do and what it costs

Last updated 2026-08-14

what does a mosquito exterminator actually do?

A mosquito exterminator, usually called a mosquito control technician in the industry, walks your property looking for standing water and resting sites, then applies a liquid barrier treatment to shrubs, tall grass, mulch beds, and the undersides of leaves where adult mosquitoes rest during the day. That's the core service. Some companies also offer larvicide treatments for water features you can't drain (ponds, rain barrels) and install misting systems that automate the spray on a timer. The barrier spray itself is usually a synthetic pyrethroid (permethrin or bifenthrin are common active ingredients) or, increasingly, a plant-derived option for people who want to limit synthetic pesticide use around pets and kids. These products are EPA-registered for outdoor residential use, which means the EPA has reviewed the data and set label instructions for how and where they can legally be applied. Registered is not the same as risk-free; applicators follow the label rate and reentry interval because that's the legal and safety standard, not because the product is harmless ^[1]. A real inspection also looks for the stuff you'd never think to check: clogged gutters, tarps that pool water, tire swings, the saucer under a potted plant. Female mosquitoes need standing water to lay eggs, and some species can complete their whole life cycle in water sitting in a bottle cap for about a week to ten days depending on temperature ^[2]. A tech who just sprays and leaves without mentioning your birdbath isn't doing the job right. Most companies price this as a recurring seasonal plan rather than a one-time visit, because a single spray only lasts about two to three weeks before it breaks down from UV exposure and rain.

how to get rid of mosquitoes: the short version

Getting rid of mosquitoes (or more honestly, getting their numbers down to where you can sit outside again) takes three things working together: eliminate standing water, reduce resting habitat, and apply a residual barrier treatment on a repeat schedule. Skip any one of these and the other two work a lot less well. Standing water removal comes first because it's free and it's the most effective single thing a homeowner can do. The CDC and EPA both recommend a "tip and toss" habit: walk the yard once a week and dump anything holding water for more than a few days, including flowerpot saucers, buckets, kiddie pools, and clogged gutters ^{[3] [2]}. Water that's chronically wet, like a pond or a low spot that never fully dries, needs a larvicide (Bti dunks are the common homeowner product) rather than dumping. Second, cut back the resting habitat. Adult mosquitoes spend most of the day hiding in shade: dense shrubs, ivy, tall grass, under decks. Mowing regularly and thinning overgrown beds removes a lot of that real estate. Third, a barrier spray targets the adults that are already there and keeps knocking down the next wave that flies in from a neighbor's yard, because mosquitoes travel. Most species have a flight range of a few hundred feet to a mile or more depending on species, so your own yard prep helps but doesn't fully insulate you from a wet ditch two properties over ^[1]. That's the honest limit of DIY: you can make your own yard much better, but you can't control the whole neighborhood's water.

how to keep mosquitoes away long term

Keeping mosquitoes away long term is really about maintaining the same three habits (water, habitat, treatment) on a schedule instead of doing them once and forgetting. Mosquito populations rebuild fast. A female can lay 100 or more eggs per batch and repeat that every few days over her lifespan, so a yard that was clear in June can be bad again by July if you stop checking for water ^[4]. The barrier spray cycle matters more than people expect. Most licensed applicators, including Duskproof, run treatments on a 10-14 day cycle through the active season because that's roughly how long the residual effect holds up against sun and rain. Stretch it to three or four weeks and you'll feel the gap; the last few days before a retreat are noticeably buggier than the first few. Misting systems are the other long-term option. These are plumbed nozzle systems, usually mounted along the fence line or under eaves, that release a fine spray on a timer, typically at dawn and dusk. They cost more upfront (installation plus a control unit) but need less manual scheduling once they're set up. They work well for people who host a lot, but they still need refills and seasonal shutdown, so they're not truly maintenance-free. A few habits stack on top of treatment and cost nothing: running box fans on a patio (mosquitoes are weak fliers and avoid moving air), swapping bright white porch lights for yellow "bug" bulbs, and treating standing water in gutters after every storm. None of these replace a barrier treatment, but they buy you extra comfortable hours.

what plants repel mosquitoes, and do they actually work?

A mosquito repellent plant is a plant that contains compounds mosquitoes find unpleasant or that mask the scents mosquitoes use to find people, usually citronella, geraniol, or similar essential oils in the leaves. Citronella grass, lemon eucalyptus, lavender, marigolds, rosemary, and catnip are the plants most often recommended. Here's the catch: the oil has to be released and concentrated near your skin to do anything, and a potted plant sitting still doesn't release much. University extension guidance is consistent on this: planting citronella or lavender around a patio provides little to no measurable reduction in bites compared to a real repellent, because the plant would need to be crushed or its oil extracted and concentrated to reach effective levels ^[3]. Oil of lemon eucalyptus, when extracted and formulated as a registered repellent (more than growing as a plant), is one of the few plant-based actives the EPA and CDC list as effective against mosquitoes when applied to skin ^[5]. So the honest answer: mosquito repellent plants look nice, and crushing a few citronella leaves and rubbing them on your arm might give you a few minutes of mild effect, but treat them as landscaping, not pest control. If you want a real plant-based repellent, buy a product formulated with oil of lemon eucalyptus or another EPA-registered active rather than counting on the plant in the pot. For more on formulated options, see mosquito repellent and natural mosquito repellent.

how to get rid of mosquitoes in the house

Mosquitoes in the house usually mean one of two things: they're getting in through a gap (door sweep, torn screen, a window left cracked) or they're breeding inside, which is less common but does happen in a clogged houseplant saucer, a forgotten vase of water, or a floor drain that stays damp. Start by checking screens for tears and making sure door sweeps actually touch the threshold; a gap you can slide a pencil through is enough for a mosquito. Empty and dry any houseplant saucers and vases that have been sitting for more than a few days. If you keep finding mosquitoes indoors despite tight screens, check floor drains, sump pump basins, and any indoor water feature; these hold water long enough for a full life cycle, which for many species runs about 8 to 10 days from egg to adult in warm conditions ^[2]. For immediate relief indoors, a plug-in or handheld space repellent, a fan pointed at the room, or an indoor-labeled aerosol can knock down what's already inside. None of that fixes a breeding source, though. If mosquitoes keep reappearing in the same room, that's a signal to hunt harder for standing water rather than buy another can of spray.

how to get rid of mosquitoes in the house vs backyard: what's different

The indoor and outdoor problems share a cause (standing water, and mosquitoes seeking blood meals) but need different fixes. Indoors, sealing entry points and eliminating small hidden water sources solves most cases fast, often within days. Outdoors, you're fighting an open system: mosquitoes fly in from neighboring yards, storm drains, and wetlands, so sealing your own property doesn't fully insulate you. For the backyard, source reduction still comes first (see the standing water section above), but it's paired with ongoing barrier treatment because you can't dump out a neighbor's birdbath or a roadside ditch. This is where a scheduled service earns its cost: reaching tall trees, deep hedge lines, and hard-to-access spots consistently, every treatment cycle, is a lot of physical work to keep up solo through a whole season. For a full comparison of DIY sprays, professional barrier treatments, and misting systems, see mosquito control.

how to get rid of mosquitoes in backyard, step by step

1. Walk the yard weekly and dump anything holding water for more than a few days: pot saucers, tarps, kiddie pools, clogged gutters, tire swings. 2. Treat water you can't dump, like ponds, rain barrels, or French drains, with a Bti larvicide dunk or granule, which targets mosquito larvae and is considered low-risk to fish, birds, and mammals when used per label ^[6]. 3. Mow regularly and thin dense shrubs or ivy where adults rest during the day. 4. Apply or schedule a barrier spray on vegetation, mulch beds, and shaded resting sites, repeating every 10 to 14 days through the season since the residual effect fades with sun and rain. 5. Add mechanical helpers: a fan on the patio, yellow bug-light bulbs near seating areas, and citronella candles for modest, short-range relief during a single evening. 6. If bite pressure stays high after doing all of the above for a couple of weeks, that's usually a sign of a source you haven't found yet (a neighbor's yard, a storm drain, a low wet spot) or that the interval between sprays is too long. A free yard assessment can find hidden breeding sites a homeowner walk-through misses, things like a gutter downspout that's been draining into a low spot for months.

when do mosquitoes go away for the season?

Mosquitoes typically die back once nighttime temperatures fall consistently below about 50°F, since most species become inactive and stop biting around that threshold, though a hard freeze is what actually ends adult activity for the year in most regions ^[7]. Some eggs and larvae can overwinter and survive freezing conditions, which is why populations often come roaring back the following spring rather than starting from zero. Exact timing varies a lot by region. In the Gulf Coast and parts of the Southwest, mosquito season can run nearly year-round with only a short lull in the coldest weeks. In the Upper Midwest and Northeast, the season usually runs from late April or May through the first hard frost in October or November. Your local mosquito control district or extension office will have the most accurate seasonal window for your specific county, since microclimates (urban heat, wetlands, elevation) shift the dates meaningfully within the same state . Because the exact end date is regional and weather-dependent, treat any season length you read online as typical, not guaranteed, and check with your local extension service for your area's real pattern before assuming you're done for the year.

how to get rid of ticks in the yard

Ticks and mosquitoes both thrive in the same overgrown, moist yard conditions, but ticks don't fly, so the fix leans harder on habitat modification. The CDC's core yard recommendations are to keep grass mowed short, clear leaf litter and tall brush, create a barrier of wood chips or gravel between lawn and wooded areas to discourage tick migration, and keep playground equipment and seating away from yard edges . Tick populations concentrate heavily at the lawn-to-woods edge, so that three-foot buffer strip does real work. Deer and rodents are the main hosts that carry ticks onto a property, so anything that reduces deer traffic (fencing, removing brush piles, keeping bird feeders away from play areas since spilled seed attracts rodents) also reduces tick pressure indirectly. A licensed pesticide application aimed at the yard perimeter and shaded, humid areas (not the open lawn, since ticks avoid dry sunny turf) is the professional layer on top of habitat work. Many companies that offer mosquito barrier treatments, including Duskproof, offer a similar perimeter application for ticks on the same visit or schedule, since the target zones overlap heavily. See tick repellent for personal protection options for hikes and yard work in the meantime.

how do you get rid of ticks from your yard for good?

There's no treatment, professional or DIY, that removes ticks from a yard permanently, because ticks keep arriving on deer, rodents, birds, and even the family dog. The realistic goal is knocking the population down and keeping the highest-risk zones (edges, brush, tall grass) unattractive to them, not eliminating them outright. The combination that actually moves the needle: mow tall grass, remove leaf litter and brush piles every fall, install a wood chip or gravel buffer at the woods edge, and treat that edge zone with a labeled acaricide on a schedule (often monthly during peak tick season, which is roughly spring through fall depending on region and species). Check pets for ticks after they've been in tall grass or wooded areas, since pets can carry ticks into the house even when the yard itself is well managed. One widely cited field study from the CDC and academic partners found that a single well-timed acaricide application to residential yard edges reduced tick abundance substantially compared to untreated yards, though results vary by tick species, application method, and yard layout, so treat any specific percentage as a study finding rather than a guarantee for your yard . If you've got kids or pets using the yard heavily, that ongoing perimeter treatment is usually worth the cost over trying to fully rely on habitat changes alone.

what does professional mosquito control cost, and is it worth it?

Single barrier spray visit	$50-$100+	One-time or as-needed
Seasonal barrier plan (per treatment)	$50-$90 per visit	Every 10-14 days, April-October typical
Full season barrier plan (total)	$300-$600+	6-10 treatments per season
Misting system installation	$1,500-$5,000+	One-time install
Misting system refills/maintenance	$100-$300	Per refill, several times a season	These figures reflect commonly reported ranges across pest control industry pricing data and vary by region, property size, and whether the company uses synthetic or plant-based product lines . Get a written quote before committing to a season plan; a legitimate company will walk your property first rather than quote blind over the phone. Whether it's worth it depends on how you use your yard. If you host outdoor dinners, have kids who play outside daily, or live near standing water you can't control (a pond, wetland, drainage ditch), the recurring service usually pays for itself in actual usable evenings. If you rarely use the yard between dusk and dark, aggressive source reduction plus an as-needed spray before specific events might be enough. A free yard assessment is the way to find out which category you're in without committing to a season plan first; a decent technician will tell you honestly if your yard doesn't need the full package.

Pricing varies by region, yard size, and whether you choose a recurring barrier spray or an installed misting system, but homeowners typically see the following ranges based on industry pricing surveys and service provider rate cards: | Service type | Typical cost | Frequency |

barrier spray vs misting system vs DIY: which should you pick?

Option	Best for	Downsides
DIY spray + source reduction	Small yards, tight budgets, mild pressure	Time-intensive, misses hard-to-reach resting sites, effect fades fast
Scheduled barrier service (10-14 day cycle)	Most suburban yards, moderate to heavy pressure	Recurring cost, need to be home or grant access periodically
Installed misting system	Frequent entertainers, high-pressure areas near water	High upfront cost, needs refills, some HOAs restrict visible plumbing	A scheduled barrier service hits the sweet spot for most homeowners: professional-grade product application to hard-to-reach resting sites, applied on a cycle that matches how fast the residual breaks down, without the upfront cost of plumbing a misting system into your fence line. Misting systems make more sense for people who host outdoor events constantly or who live on a lake or wetland edge where pressure is severe enough that a barrier every two weeks still isn't quite enough. DIY works fine as a supplement (or a full solution in a low-pressure yard), but most people underestimate how much labor it takes to reach every resting site every two weeks, all season, without missing spots.

Frequently asked questions

How do I get rid of mosquitoes fast before an outdoor event?

Dump all standing water in the 24-48 hours before the event, mow and trim shrubs, run box fans on the patio, and apply a barrier spray at least a day ahead so it has time to dry and settle onto foliage. A same-week professional treatment or a fogging service for the specific event date is the fastest option if you're short on time.

How often should a professional mosquito treatment be reapplied?

Most licensed applicators recommend every 10 to 14 days during active mosquito season, since the residual effect of a barrier spray breaks down from UV exposure and rain within about two to three weeks. Heavy rain can shorten that window and may call for an earlier retreatment.

What is a mosquito repellent plant, exactly?

It's a plant, like citronella grass, lavender, or lemon eucalyptus, that naturally contains oils mosquitoes find unpleasant. The oil has to be released and concentrated to work well, so an intact potted plant gives minimal protection compared to a formulated repellent using the same active ingredient on skin or clothing.

Do ultrasonic mosquito repellers actually work?

There's no strong independent evidence that ultrasonic repeller devices reduce mosquito bites. Most controlled tests find little to no measurable effect, and neither the EPA nor major university extension programs list ultrasonic devices as a verified mosquito control method. Standing water removal and registered repellents remain the evidence-backed options.

When do mosquitoes go away for the winter?

Adult mosquitoes typically stop biting once nighttime temperatures fall consistently below about 50°F, with a hard freeze ending activity for the season in most regions. Some eggs and larvae survive winter and hatch again in spring, so populations rebuild rather than starting from scratch. Exact timing varies by region and species.

How do you get rid of ticks in the yard without chemicals?

Mow grass short, remove leaf litter and brush piles, and build a three-foot buffer of wood chips or gravel between lawn and wooded edges, since ticks avoid dry, sunny, open turf. Keep play areas and seating away from yard edges and reduce deer and rodent access, since they carry ticks onto the property.

How do I get rid of mosquitoes in my house permanently?

Seal gaps in screens and door sweeps, and find and eliminate any indoor standing water like a plant saucer, vase, or damp floor drain, since a full mosquito life cycle can complete indoors in about 8 to 10 days in warm conditions. Once entry points and water sources are gone, indoor mosquitoes usually stop reappearing.

What plants repel mosquitoes best, if any?

Citronella grass, lemon eucalyptus, lavender, marigolds, and catnip contain oils mosquitoes dislike, but the effect from an intact plant is mild since the oil needs to be released to work. They're reasonable landscaping choices, not a substitute for a registered repellent or a barrier treatment program.

Is professional mosquito control safe for pets and kids?

EPA-registered barrier products are legal for residential use when applied according to the label, including stated reentry times after treatment. That's not the same as "harmless"; follow the technician's guidance on when pets and kids can return to treated areas, and ask about plant-based product options if you want to minimize synthetic pesticide exposure.

Can a mosquito exterminator get rid of ticks too?

Many companies that treat mosquitoes offer a similar perimeter treatment for ticks, since both pests concentrate in the same shaded, humid yard edges. It's often bundled into the same service visit. Ask specifically, since not every mosquito-focused company carries a tick-labeled product or license in every state.

How much does it cost to hire a mosquito exterminator?

A single visit typically runs $50 to $100 or more, while a full seasonal plan with treatments every 10 to 14 days often totals $300 to $600 or more depending on yard size and region. Misting system installation costs considerably more upfront, often $1,500 to $5,000-plus, but needs less manual scheduling.

Will a barrier spray get rid of mosquitoes completely?

No. A barrier treatment knocks the existing population down significantly and keeps suppressing new arrivals between visits, but it doesn't eliminate mosquitoes from an area permanently, since new adults keep flying in from neighboring properties and water sources. Combining it with standing water removal gets the best realistic results.
