How to Get Rid of Mosquitoes in Your Yard

How do you get rid of mosquitoes in your yard, step by step?

The lasting fix is to stop your yard from producing mosquitoes. CDC's advice for the outdoors starts with one weekly habit: once a week, empty and scrub, turn over, cover or throw out items that hold water, such as tires, buckets, planters, toys, pools, birdbaths, flowerpot saucers and trash containers ^[1]. Penn State Extension notes that many mosquito problems can be traced to backyard containers filled with water ^[9].

1. Walk the yard once a week. Look for anything holding water, including a tarp, a wheelbarrow or a toy.
2. Dump and scrub. Empty the water and scrub the inside walls of containers you keep, so eggs stuck above the waterline go too.
3. Flip, drill or toss. Turn over kiddie pools and wheelbarrows, drill drain holes in the bottoms of recycling bins left outdoors, and get rid of old tires.
4. Cover what you store. Put tight lids on rain barrels and other water storage, or cover open tops with mesh too fine for a mosquito.
5. Fix the slow spots. Clean clogged gutters, fill tree holes, and avoid overwatering the lawn and beds.
6. Treat what you cannot drain. Use a larvicide labeled for the site in ponds, rain barrels or other water you cannot dump or cover.

One weekly walk to dump, scrub and cover standing water does more against yard mosquitoes than any spray.

Mosquito season is typically June through October across much of the U.S., according to CDC's West Nile virus page, and the season varies by region ^[7]. Start the weekly routine as soon as the weather warms and keep it up until the first hard frost.

Why does standing water matter so much?

Every mosquito starts life in water. Mosquitoes pass through four stages: egg, larva, pupa and adult, and the larvae (often called "wigglers") and pupae both live in the water ^[2]. CDC says an egg takes 7 to 10 days to become an adult, and UC IPM adds that in summer the whole cycle can take a week or less, depending on water temperature ^[8]. That timing is why the cleanup is weekly: dumping water every 7 days kills the larvae before they can fly.

Aedes mosquitoes, including the Asian tiger mosquito, are the container breeders most yards produce, and their biology explains the cleanup routine:

Aedes fact	What it means for your yard
Eggs are laid on the inner walls of containers, just above the waterline	Look inside buckets, tires, planters, toys and saucers, not just at open water
Eggs survive drying for up to 8 months, then hatch when flooded	An empty container can still hold eggs; scrub it or store it upside down
Egg to adult takes about 7 to 10 days	Dump and scrub standing water at least once a week
Ae. aegypti live indoors and outdoors; Ae. albopictus outdoors	Check indoor plant saucers and vases too

Details from CDC's Aedes life cycle page ^[2]. Because Aedes eggs cling to container walls and survive drying for up to 8 months, scrub containers instead of just tipping them out.

Your yard's water mostly feeds your yard's mosquitoes. CDC says the Aedes species fly only a few blocks in their lifetime, and Penn State says most mosquitoes stay within half a mile of where they bred, although some fly many miles. So a clean yard really does cut the number of bites, and a neighbor's neglected pool can undo some of the work.

Where do mosquitoes breed in a yard?

Anywhere water sits for a week. The list is longer than most people expect, so it helps to walk the yard in a loop.

Spot	What to do	Source
Buckets, planters, toys, saucers, trash cans	empty and scrub weekly, or store upside down	CDC
Birdbaths and pet dishes	change the water every week	UC IPM
Old tires	get rid of them or keep them dry	Penn State, CDC
Rain barrels, cisterns	tight lid, or mesh smaller than a mosquito	CDC
Roof gutters	clear leaves and debris at least once a year	UC IPM, Penn State
Recycling bins	drill drain holes in the bottom	Penn State
Kiddie pools, wheelbarrows	turn over when not in use	Penn State
Tree holes	fill with sand or mortar	UC IPM
Lawn and beds	avoid overwatering that leaves puddles	UC IPM
Septic tank	repair cracks; cover vents and pipes with fine mesh	CDC

What can you do about water you cannot dump?

Ponds, water gardens and rain barrels you want to keep need a different approach. UC IPM suggests removing excess vegetation from ponds, stocking them with mosquito-eating fish, or using products containing Bacillus thuringiensis (Bt), a bacterial larvicide ^[8]. Mosquitofish work best in man-made water that does not connect to natural waters, and UC IPM warns that they should never be released into streams, ponds or lakes.

CDC says larvicides are for water that will not be used for drinking and cannot be covered or dumped out, and to always follow label instructions ^[1]. Pick an EPA-registered larvicide labeled for the kind of water you are treating (a rain barrel, a pond with fish, a birdbath), and use only the amount the label states. Read and follow the label. The label is the law. Keep children and pets away from the product and the treated water as the label directs.

Do yard sprays, foggers, misting systems and zappers work?

They help much less than people hope. UC IPM says outdoor sprays can temporarily reduce the number of adult mosquitoes but have no lasting effect, and that control should focus on larvae and standing water ^[8]. A sprayed yard fills up again as new adults hatch from the water nearby.

• Spot treatments for adults. CDC says an outdoor adulticide can be used where adult mosquitoes rest, such as under patio furniture or in a carport or garage, following label instructions. If you use one, choose an EPA-registered insecticide labeled for outdoor mosquitoes. Read and follow the label. The label is the law. Keep children and pets out of the area until the label says it is safe, and avoid spraying where bees and butterflies are feeding.
• Foggers. Penn State's advice is that if you must fog, do it in the evening when mosquitoes are active and follow all directions on the label ^[9].
• Backyard misting systems. CDC does not recommend misting systems for homeowners or residential areas. It notes that they spray on a timer without mosquito surveillance, can harm bees and butterflies, and may expose people and pets ^[4].
• Bug zappers. UC IPM calls electric zappers counterproductive because many of the insects they kill are ones that prey on mosquitoes.
• Ultrasonic devices. UC IPM lists them as ineffective, and Penn State says they have not been proven to prevent mosquito bites.

How do you keep mosquitoes out of the house and off you?

While you work on the yard, keep mosquitoes outside. CDC recommends installing and repairing window and door screens, keeping doors (including garage doors) closed instead of propped open, using air conditioning when you can, and emptying indoor water holders such as vases and saucers each week ^[1]. Penn State says to make sure screens are "bug tight." A whine in the bedroom at night often points to a torn screen or an open door.

Outdoors, plan around the times mosquitoes are busiest. Penn State notes that mosquitoes are most active at dawn, dusk and early evening, and suggests long sleeves and long pants then; UC IPM adds that some species bite during the day. For personal protection, CDC's advice is simple: use an EPA-registered insect repellent and always follow the label instructions ^[5].

Not every long-legged fly is a mosquito. UC IPM notes that non-biting midges and large crane flies (sometimes called "mosquito hawks") are often mistaken for mosquitoes, and crane flies do not actually eat mosquitoes. Small flies hovering over houseplants are more likely fungus gnats; see how to get rid of gnats or the mosquito profile.

When does local mosquito control help, and when should you call a professional?

Mosquito control is mostly a local government job. CDC explains that local governments and mosquito control districts track how many mosquitoes there are and which kinds, find standing water, treat it with larvicides, and apply adulticides by backpack, truck or airplane when surveillance shows rising mosquito numbers or virus activity ^[3]. That work can reach water one household cannot, such as ditches, storm drains and abandoned pools.

Contact your local program when:

• Mosquitoes stay heavy after two weeks of weekly cleanup in your yard. The source may be off your property. UC IPM tells homeowners to contact their county mosquito and vector control agency for local management information, and Penn State suggests reporting trouble spots to municipal authorities.
• You find water you cannot fix, such as a clogged storm drain, a roadside ditch or a neighbor's abandoned pool.
• You want to know what is sprayed in your area or when. Your local program or health department can tell you.

A licensed pest professional is worth calling if mosquitoes keep showing up indoors after you have screened, closed doors and emptied containers; CDC lists hiring a pest control professional as an option for treating indoor areas.

Most mosquito bites only itch. CDC says to see a healthcare provider if bite symptoms get worse or a bite looks infected (red, warm, or with a red streak spreading from it) ^[6], and to talk to a healthcare provider if you think you or a loved one might have West Nile virus. Our bites section and the bite identifier help you sort out what bit you.
