Short Answer
Mosquitoes are common in the Yosemite area, especially during the warmer months.
They can be found near water sources such as ponds, lakes, and rivers.
However, the abundance of mosquitoes can vary from year to year and from location to location.
It is always a good idea to bring insect repellent when visiting Yosemite in order to help protect yourself from mosquito bites.
Types of Mosquitoes in Yosemite
When it comes to mosquitoes in Yosemite National Park, there are two distinct types: the non-biting variety and the biting variety. Non-biting mosquitoes, also known as “nuisance mosquitoes,” are primarily active during the daytime and are typically found near water sources, such as lakes, streams, and rivers. They are not known to spread diseases and are usually considered harmless. Biting mosquitoes, on the other hand, are active at night and can spread a variety of diseases, including West Nile virus. They are usually found in shady, damp areas and are more likely to bite humans and animals.
In Yosemite, the most common types of biting mosquitoes are the Culex tarsalis, Aedes vexans, and Aedes albopictus.
The Culex tarsalis is the most common vector for West Nile virus, and it is typically found near water sources.
The Aedes vexans and Aedes albopictus species are usually found in shady, damp areas and can potentially spread other diseases, such as dengue fever.
The park has also seen an increase in the number of non-biting mosquitoes due to the presence of several large reservoirs.
The reservoirs provide an ideal breeding ground for these types of mosquitoes, which can cause a nuisance for visitors but do not pose any health risks.
Mosquito-borne diseases, such as West Nile virus, are a real concern in Yosemite National Park, and visitors should take the necessary precautions to protect themselves.
Wearing long sleeves and pants, using insect repellent, and avoiding standing water are all effective ways to reduce the risk of being bitten by mosquitoes.
In addition, those going camping or on backcountry trips should consider installing mosquito netting to help keep mosquitoes away.
Where to Find Mosquitoes in Yosemite
The presence of mosquitoes in Yosemite National Park can be found in a variety of habitats.
The most common species of mosquito in Yosemite is the Culex tarsalis, which is typically found in low-lying areas near water sources like rivers, streams, and lakes.
They are also commonly found in meadows and grassy areas, especially in the warmer months when temperatures are higher.
Mosquitoes in Yosemite can also be found near areas where there is standing water, such as in areas that are prone to flooding.
They can also be found in wet areas such as pools and other areas that collect water.
In addition, mosquitoes in Yosemite can also be found in marshy areas, such as along the banks of rivers and streams.
They are also commonly found in areas where there is high vegetation, such as near bushes and shrubs.
Mosquitoes in Yosemite can also be found in shaded areas, such as in areas that are heavily wooded or have a lot of shade.
Finally, mosquitoes in Yosemite can also be found in areas where humans are present, such as near picnic areas and campgrounds.
This is because mosquitoes are attracted to the carbon dioxide we exhale, and they can be found in higher concentrations near areas where people congregate.
What to Wear for Protection
When it comes to protecting yourself from mosquitoes in Yosemite National Park, the best advice is to wear long sleeves and pants.
Though many of the mosquitoes in Yosemite are of the non-biting variety, it’s still important to take precautions against being bitten.
Long sleeves and pants are the best way to do this, as they will provide the most coverage and protection from mosquitoes.
Additionally, wearing light-colored clothing can also help to keep mosquitoes away, as mosquitoes are more attracted to dark colors.
It’s also a good idea to wear a hat or other protective headgear when visiting Yosemite.
Mosquitoes are known to be particularly attracted to the head and face, so wearing a hat or other covering can help to keep them away.
Additionally, wearing shoes that cover the entire foot can also help to protect against bites, as mosquitoes may be attracted to areas of exposed skin on the feet.
In addition to wearing the proper clothing, using insect repellent can also help to keep mosquitoes away.
Repellents containing DEET can be effective in keeping mosquitoes away, though some repellents may be toxic to animals and should be used with caution.
Additionally, avoiding standing water can also help to reduce the number of mosquitoes in the area, as standing water is a breeding ground for mosquitoes.
Finally, installing mosquito netting is another effective way to protect against mosquitoes in Yosemite.
Mosquito netting can be used while camping or on backcountry trips, and can provide effective protection against mosquitoes.
However, it’s important to make sure that the netting is securely fastened and that there are no gaps through which mosquitoes can enter.
Repellents and Netting for Extra Protection
When it comes to protecting yourself from mosquitoes in Yosemite, repellents and netting are essential.
Repellents are the first line of defense against these pesky bugs, and there are a variety of repellents available to choose from.
DEET, picaridin, and oil of lemon eucalyptus are all common active ingredients in mosquito repellents.
When using repellents, it is important to follow the directions on the packaging to ensure maximum effectiveness.
In addition to repellents, mosquito netting is also a great way to protect yourself from mosquitoes while camping or backpacking in Yosemite.
Mosquito netting can be used to cover tents or sleeping bags, and it is an effective way to reduce the number of mosquitoes that can get close to you.
It is also important to make sure that your tent or sleeping bag is sealed tightly, as mosquitoes can find their way into small cracks or openings.
Finally, it is also important to avoid standing water when visiting Yosemite, as mosquitoes tend to breed in these areas.
Mosquitoes can lay their eggs in even the smallest puddles, so it is important to keep an eye out for these areas and avoid them.
By taking these simple precautions, you can ensure that you are protected from mosquitoes while visiting Yosemite National Park.

This is especially true when camping or doing backcountry trips, where extra precautions, like installing mosquito netting, are necessary.
The most common diseases transmitted by mosquitoes in Yosemite are West Nile virus, La Crosse encephalitis, and Eastern equine encephalitis.
West Nile virus is a potentially serious infection that can cause flu-like symptoms, such as fever, headache, body aches, and a rash.
La Crosse encephalitis is also a serious infection that can cause fever, headache, nausea, vomiting, and a rash.
Eastern equine encephalitis is a rare but potentially fatal infection that can cause fever, headache, confusion, and seizures.
