Do you hear a buzzing sound as you relax in your garage with a glass of wine? It’s not your imagination. There is a mosquito buzzing in your ear. And it’s not alone. The buzz of a mosquito is most annoying. So naturally you want to know how to get rid of mosquitoes in your garage?

Mosquitoes are not just irritating. Their bite is painful and can spread all kinds of diseases.

To keep mosquitoes away from your garage you have to use a 4 pronged strategy:

  • Repel them using sprays or balms so they don’t bite you
  • Get Rid of them by killing them with insecticides or traps
  • Prevent them from entering using screens and natural plants
  • Control their population around your garage

What is the Most Effective Mosquito Repellent?

You can use a mosquito repellant spray or balm to keep them at bay. Mosquito repellents do not kill them, but the smell will keep them away. Mosquito repellants can be used in the garage, if the number of mosquitoes is small and you just want to protect yourself from the buzzing and the bites. 

The smell of some essential oils such as citronella, lemon, eucalyptus, lavender, and tea tree oil might keep mosquitoes at bay. Sprays or candles using these scents can be useful, but won’t control them or get rid of them in the long run.

Thermacell is the most popular brand. The brand offers several models. You can check out Thermacell Radius Zone Mosquito Repellent, Gen 2.0, Black, Rechargeable; Includes 12 Hr Mosquito Repellent Refill; No Candle or Flame, Easy To Use & Long Lasting Bug Spray/DEET Alternative on Amazon or look for a model that better meets your needs.

It will repel mosquitoes without chemicals or sprays on your skin. No lotions or DEET to apply. No smoke, flames, or citronella. No messy traps to clean. Independently tested. EPA reviewed for safety & effectiveness.

However, if your garage is infested with mosquitoes, repelling them is only a temporary respite. So…

How to Get Rid of Mosquitoes from Your Garage?

Mosquitoes along with flies and other flying insects are food for spiders. So by getting rid of mosquitoes in your garage, you are also taking a step towards getting rid of spiders in your garage. 

If spiders do not find mosquitoes & flies, they may give your garage a miss. Learn more about cobwebs & spiders on my post How To Get Rid Of Cobwebs From Your Garage? What You Need To Know!

To get rid of mosquitoes that have already infested your garage you have to kill them by using an insecticide, trapping them or by zapping them.

Insecticide Sprays that Kill Mosquitoes

Insecticide sprays kill mosquitoes by coming in contact with the mosquitoes. They use a chemical called pyrethrum. 

However, for the spray to really work you need the spray to be in the air for at least an hour. Moreover, you must spray it in every nook & corner of the garage as the mosquitoes will be hiding. The best way is to fog the garage before retiring for the night.

Raid is an effective mosquito killer. You can check it out on Amazon by clicking the link or picture below.

  • Kills: Asian Lady beetles, boxelder bugs, flies, fruit flies, hornets, mosquitoes, non-biting gnats, small flying Moths, wasps, yellow jackets
  • Can be used as both an outdoor and indoor insect killer

Kill the Mosquitoes with Electronic Zappers

Mosquitoes are attracted to humans and sense their presence by the temperature and CO2 emission. Electronic Killers use light to mimic this, attract them, trap them and kill them. 

They are better than insecticide sprays as they are non-toxic. Moreover, they are active in attracting the mosquitoes and hence more effective.

You should use an electronic mosquito killer for a few days to get rid of mosquitoes if your garage is infested.

You can get rid of common pests like flies, mosquitoes, spiders, moths and roaches from your garage. I have a blog post on each of these pests that you can check out at

What Really Works to Keep Mosquitoes Out of the Garage?

Use of Barriers & Screens

To keep mosquitoes out of your garage consider the following advice from CDC

  • Install or repair and use window and door screens.
  • Close doors, including garage doors. Do not leave doors propped open.
  • Use air conditioning when possible.

In fact I am a great advocate of using climate control in your garage. Find out more from my blog post How To Make Sure Of Best Climate Control For Your Garage

LG 18,000 BTU Single Zone Mega Mini Split Heat Pump available at Sylvane is ideal for the garage.

This single-zone mini split can do it all and that’s why it’s the perfect choice for year-round comfort. Multiple operating modes deliver the performance you need for any season.

  • Cool Mode: Its 18,000 BTUs of cooling power fights back against rising summer temperatures.
  • Heat Mode: When winter arrives, stay comfortable indoors with its 18,000 BTUs built-in heat pump.
  • Moisture Elimination: A dehumidification setting helps to eliminate stuffy indoor air and prevent mold growth by removing excess moisture from your space.
  • Fan Only Setting: In its air circulation operation, the system will move air around the room without increasing or decreasing your set temperature.

Of course if your garage is climate controlled you will not need to keep your garage door open that often.

If you want to keep the garage doors open for some time, then do make sure that you have a garage door screen in place and it is closed.

There are Smells that Mosquitoes Hate but we Love

  1. Basil
  2. Lavender
  3. Rosemary
  4. Sage
  5. Mint
  6. Lemongrass
  7. Catnip
  8. Citronella
  9. Garlic
  10. Marigold
  11. Scented Geranium

Why is your Garage Infested with Mosquitoes?

Mosquitoes are not born inside your home. They are born outside your home, on some stagnant water body nearby. Do you live near a marsh or a lake? Though fish continuously feed on mosquito eggs & larva, enough still survive.

Mosquitoes can breed on even small, shallow pools of water around your garage. Ditches, ponds, and puddles in your front or back yard can be mosquito breeding grounds. They can even lay their eggs on water in bird baths, flower pots or overturned trash can lids!

Mosquitoes hate wind and are always looking for shelter. Your yard provides them with just that. They can use raked leaves, tall grass and compost piles to take refuge.

To get rid of mosquitoes dispose off raked leaves regularly

The combination of the above two makes your house and particularly your garage vulnerable to an invasion by mosquitoes. 

They may find it somewhat difficult to enter your house because you rarely open the doors and windows. Your house is climate controlled. 

You have an HVAC (Heating, Ventilation & Air Conditioning) system installed and working. In addition, your doors & windows likely have insect screens too!

The big wide garage door, on the other hand, opens at least a few times a day. It is an open invitation for mosquitoes to come and get your blood! They can also use your garage as a shelter from wind.

What is the Way to Control the Breeding of Mosquito Larvae around the Garage?

You can control the mosquito population around your garage. Less the mosquitoes nearby, less the chances they will infest your garage. You can do this by 

Reducing Mosquito Breeding Spots around your Garage

Mosquitoes lay their eggs on still water. Even a very small shallow patch that has water or can collect rainwater, will do. Be on the lookout for such spots. Often small steps like filling them up, keeping them overturned, drilling holes in them will work.

A few examples (certainly not a full list):

To get rid of mosquitoes refresh water in bird baths regularly
  • Bird baths – change the water everyday or install a water feature that keeps the water in motion
  • Pet water bowls – refresh regularly
  • Lotus ponds – introduce fish such as goldfish or guppies which will eat up the mosquito eggs and larva
  • Flower pots – ensure the bottoms have holes to drain out the water
  • Drains – clean regularly to avoid water blockage
  • Wheelbarrows, watering cans etc, – store indoors or overturned
  • Potholes in driveway – repair & fill up as soon as possible

Reducing Hiding Spots for the Mosquitoes

Mosquitoes do not like wind and try to take shelter. You must try to remove the objects that naturally provide shelter to them.

  • Tall grass in front or back yard
  • Piles of raked leaves, twigs, firewood

Encourage the Natural Predators to eat up the Mosquito Larvae

Having some natural predators in your garden will also help in controlling the mosquito population around your garage and your house. A few examples:

  • Fish in ponds – goldfish, guppies, mosquito fish
  • Frogs & Tadpoles
  • Dragonflies
  • Birds – swallows, purple martins, waterfowl

Using Outdoor Mosquito Killers

You can use insecticide sprays to regularly spray the lawn & garden around your house. However, this method is often not very effective. It may be better to install a few electrical outdoor mosquito killers, especially close to the garage door.

A Few Basic Facts about Mosquitoes (Interesting!)

Mosquitoes are insects that belong to the Order Diptera, which means they have two (di-) wings (-ptera). This Order includes Flies as well. In an earlier post I have covered How To Get Rid of Flies From Your Garage? What You Need To Know

There are over 3,000 species of mosquitoes around the world, of these 176 are found in the US. It’s the house flies and mosquitoes that invade our homes. 

Mosquitoes are very small, about 1/8 – 3/8″ long. They have two wings &  six legs, just like the house fly. Both are annoying. Worse both can carry and spread diseases. 

However, mosquitoes are more dangerous. Unlike flies, they bite and suck blood. Well, to be fair the male mosquitoes don’t. Only the females do. The bite is enough to give you an itch and a red welt on your skin.

The mosquito uses two tubes to bite. It injects saliva into your skin through one which has an anti-clotting enzyme. It sucks blood through the other. The female needs the blood, not for itself, but as protein for its eggs.

Mosquitoes, worldwide, are the biggest killers. According to an WHO estimate, mosquitoes kill over a million people each year. Mostly in the developing world. And mostly among children & elderly.

Malaria is the most common cause of death, especially in third world countries.

Fortunately, malaria has been eradicated in the United States since the late 1940s. However, West Nile virus, dengue fever and Eastern equine encephalitis (EEE) are still a concern in the U.S.

Mosquitoes lay their eggs on still water. 

“Fish and other predators keep large ponds and streams relatively mosquito-free; instead, mosquito hotspots include temporary puddles, tree holes, discarded car and truck tires and potted plant saucers, according to the U.S. Environmental Protection Agency (EPA).”


Mosquitoes feed on nectar and most will feed at dusk & dawn. This is why you can see a swarm of mosquitoes at sunset, if you are out in a park.

Fun Fact: Mosquitoes are more attracted to people with high metabolic rates such as joggers & runners. But that is no excuse to give up on working out!

Bottom Line

The bottom line is that mosquitoes are annoying, blood sucking insects that can also spread deadly diseases. They will lay eggs on even very small patches of still water. To win the war against these tiny, yet mighty menaces, you must

  • Repel mosquitoes so they do not irritate & bite
  • Get Rid of mosquitoes by killing them
  • Prevent mosquitoes from entering your garage
  • Control mosquito population around the house
