Does Sunscreen Repel Mosquitoes?

Are you planning a trip to a semi-tropical destination this summer? Then you must be wondering if your sunscreen will be enough to keep pesky mosquitoes away.

Does sunscreen repel mosquitoes? I’m going to share the facts, and let you know if using sunscreen will help repel mosquitoes…

Does Sunscreen Repel Mosquitoes?

What Attracts Mosquitoes?

One of the key elements that attract mosquitoes is carbon dioxide (CO2). When we breathe out CO2, mosquitoes detect this gas using their specialized receptors and get lured towards us.

This trait makes them especially drawn to larger people or pregnant women who tend to emit more CO2.

Your body heat and sweat can also play significant roles in attracting these pests.

Mosquitoes have an uncanny ability to sense heat; hence they are often found hovering around warm-blooded creatures like us humans.

Sweat not only increases your body temperature but also releases lactic acid – another element highly attractive to mosquitoes.

Our skin microbiota produces natural scents which may be appealing to these insects as well.

Certain bacteria on our skin break down sweat into acids such as uric acid and lactic acid which draw in mosquitoes.

Lastly, believe it or not, even your clothing color could influence how attractive you are to mosquitoes.

Darker clothes stand out against the horizon during dusk when most mosquito species feed, making you easily noticeable.

What Is The Best Way To Repel Bugs?

Citronella oil is widely acclaimed to be one of the most effective methods out there, alongside bug repellent.

This essential oil derived from a variety of lemongrass species has been used for centuries to repel bugs and insects, including mosquitoes.

Its strong scent masks the human odors that attract these pesky creatures, making you less appealing to them.

Your arsenal against bugs isn’t limited to just citronella oil, though. There are several other ways to keep these unwelcome guests at bay:

  • DEET: A powerful chemical insect repellent that can provide long-lasting protection against mosquitoes and ticks.
  • Picaridin: Another synthetic option that’s odorless and doesn’t leave a greasy residue on your skin or clothes.
  • Lemon Eucalyptus Oil: A natural alternative that offers comparable protection to DEET.

Remember that the best way to repel bugs often involves combining multiple methods.

For instance, wearing clothing treated with permethrin (an insecticide) while also applying an insect repellent onto your exposed skin can significantly increase its effectiveness.

While these solutions help in keeping pests away from you, they might not completely eliminate bites or stings from occurring.

Don’t depend solely on these but also to take preventative measures such as avoiding areas where pests are known to populate or breeding grounds like stagnant water bodies.

Should You Put Bug Spray or Sunscreen First?

Should You Put Bug Spray or Sunscreen First?

It’s generally advised to lather on your UV protection first, allowing it to fully absorb into your skin before spritzing on your insect deterrent.

This method ensures that each product performs its function effectively without interference from the other.

When you’re using sunscreen and insect repellent together, there are certain steps you should follow. 

Step Action Reason
1 Apply Sunscreen First Allows for full absorption and adequate UV protection
2 Wait for Absorption Ensures sunscreen doesn’t mix with bug spray
3 Apply Bug Spray Forms a layer over the sunscreen without diluting its efficacy
4 Avoid Eye Area Prevents irritation of sensitive areas
5 Reapply Sunscreen Maintains protection as some may be lost during bug spray application

The order does matter, as applying bug spray first could potentially decrease the effectiveness of your sunblock by preventing it from absorbing properly into your skin.

Not only is this approach scientifically accurate, but also very practical – particularly if you plan on spending extended periods in environments where both sun exposure and bugs are significant concerns.

Does Sunscreen Repel Mosquitoes?

Sunscreens are primarily designed to protect your skin from harmful UV rays and not specifically intended to repel insects.

In fact, some research suggests that certain ingredients in sunscreen may even attract mosquitoes.

Make sure you understand the distinct roles of sunscreen and insect repellent:

  1. Sunscreen: It is used for protecting your skin from damaging UV rays. It doesn’t include any ingredients that would keep mosquitoes at bay.
  2. Insect Repellent: This product is explicitly formulated to deter pests like mosquitoes. They contain ingredients such as DEET or Picaridin which effectively keep mosquitoes away.
  3. Combination Products: Some products combine sun protection and bug repellence, but they’re not always recommended due to differing reapplication times for maximum effect.
  4. Alternating Applications: If you’re using separate products, apply the sunscreen first, so it can fully absorb into your skin before you apply insect repellent.

So, does sunscreen repel mosquitoes? The short answer: No.

To ensure full protection against both harmful sun rays and pesky insects during those long summer days outside, it’s best practice to use both a high SPF sunscreen and an effective insect repellent separately instead of relying on one product for dual purposes. 

Does Sunscreen Attract Mosquitoes?

Sunscreen itself does not particularly lure mosquitoes, but certain ingredients present in some sunscreens can indeed draw them closer.

These bloodsuckers are attracted by lactic acid and other chemicals emitted through our skin, which are often found in many skincare products including sunscreen.

A study published in the Journal of Insect Behavior noted that insects like mosquitoes are attracted more towards people who have recently applied lotions or creams on their skin.

The researchers concluded that it’s not necessarily the product itself but rather the extra moisture and scent these products add to your skin that attracts mosquitoes.

So while sunscreen doesn’t directly attract mosquitoes, if you’re using a scented product or one with added moisturizers, you could be inadvertently making yourself a target for these biting nuisances.

This doesn’t negate the importance of wearing sunscreen when out in sunny conditions as its primary function is to protect against harmful UV rays – something far more detrimental than mosquito bites.

Don’t let this deter you from applying sunblock, though! Opt for unscented varieties when possible and consider using insect repellents alongside your SPF lotion.

Protecting your skin should always come first regardless of whether it might mean attracting an annoying buzz or two along the way.

Can Insect Repellent Affect Your Sunscreen Working?

Can Insect Repellent Affect Your Sunscreen Working?

Both sunscreen and insect repellent are essential in protecting your skin from harmful elements, but is it possible that one could compromise the other?

The answer is not straightforward as there are several factors at play:

  • The type of sunscreen you’re using: Not all sunscreens work the same way. Some rely on physical barriers like zinc oxide or titanium dioxide, while others use chemical absorbers.
  • The order of application: Whether you’re applying sunscreen before or after the insect repellent can make a difference.
  • The type of insect repellent: For instance, an insect repellent with DEET may have different effects compared to other types.
  • Your reapplication routine: Sunscreen needs to be reapplied every two hours and immediately after sweating or swimming.
  • How much product you’re using: Applying less than recommended can reduce both your sun protection and bug defense.

According to research studies, applying an insect repellent with DEET after applying sunscreen does indeed decrease the SPF (sun protection factor), affecting the effectiveness of sunscreen by up to 34%.

This means that even though you’ve applied adequate amounts of sunblock, its ability to protect against UV rays decreases when combined with DEET-based repellents.

How To Prevent Mosquito Bites

To start with, it’s essential to understand that mosquitoes are attracted to certain scents and chemicals emitted by our bodies.

Therefore, altering these cues can help deter them. Contrary to popular belief, there isn’t much scientific evidence supporting that sunscreen repels mosquitoes.

So relying solely on your sunscreen might not be enough for preventing mosquito bites.

So what other steps can you take? Firstly, consider wearing light-colored clothing that covers most of your body when in an area known for its mosquito population.

Mosquitoes tend to be more attracted to dark colors and are less likely to bite through clothes. Secondly, avoid being outside during peak mosquito activity times—usually dawn and dusk.

Using a good quality insect repellent containing DEET or picaridin can significantly reduce the chance of getting bitten.

These substances work by blocking the receptors mosquitoes use to detect their prey — us! Remember though; they should be applied after applying your sunscreen for maximum protection.

Regularly removing standing water around your home where mosquitoes breed is another effective strategy. Finally, if possible, try sleeping under a bed net treated with long-lasting insecticide.

What Are the Potential Side Effects of Using Sunscreen and Insect Repellent Together?

Using sunscreen and insect repellent together isn’t generally harmful. However, you might experience skin irritation or allergies, especially if you have sensitive skin.

Sunscreen’s effectiveness may lessen as some repellents can dilute it.

DEET-based repellents could increase your skin’s absorption of chemicals in the sunscreen.

Lastly, reapplying this combination frequently could lead to overexposure to both products’ active ingredients.

Can Mosquitoes Transmit Diseases and If So, What Are They?

Can Mosquitoes Transmit Diseases and If So, What Are They?

Yes, mosquitoes can transmit diseases. They’re responsible for spreading various harmful illnesses such as Malaria, Dengue Fever, Zika Virus, and West Nile Virus.

When a mosquito bites an infected person or animal, it picks up the disease-causing virus or parasite.

The next time it bites someone else, it injects these pathogens into their bloodstream.

Make sure you protect yourself from mosquito bites to reduce your risk of contracting these diseases.

Are There Natural Alternatives to Sunscreen and Bug Spray that Can Repel Mosquitoes?

Absolutely, there are natural alternatives to repel mosquitoes. Citronella oil, a natural plant-based insect repellent, is commonly used. Other essential oils like lemongrass and eucalyptus can also deter these pests.

As for sun protection, consider using raspberry seed oil or carrot seed oil which offer some UV protection. However, their effectiveness isn’t as well-studied as conventional sunscreens.

How Does the SPF Factor in Sunscreen Affect Its Ability to Repel Mosquitoes?

The SPF factor in your sunscreen does not affect its ability to repel mosquitoes. SPF, or Sun Protection Factor, measures how well the product blocks UVB rays from damaging your skin. It doesn’t have any attributes that would deter mosquitoes.

If you want to protect against both sun and bugs, consider a dual-purpose product with insect repellent as well as sunscreen.

However, remember that these may need to be reapplied at different rates for optimal protection.


What Type of Mosquitoes Are More Attracted to Humans and Why?

You’re most attractive to female mosquitoes, specifically those of the Aedes aegypti and Anopheles gambiae species. They feed on human blood for protein to produce eggs.

Factors like carbon dioxide output, body heat, and certain chemicals in sweat draw them in.

Interestingly, they have a keen sense of smell and are particularly attracted to lactic acid, uric acid, ammonia and other compounds present in your sweat.


Sunscreen does not directly repel mosquitoes, as it is designed to protect your skin from UV radiation and not specifically deter pests.

That being said, some ingredients contained in certain varieties of sunscreen could potentially draw these pests towards you. It’s best practice to combine sunscreen with insect repellent for maximum protection.

Apply the sunscreen first so that it can absorb properly into your skin before spritzing on your insect deterrent.

Make sure both products are reapplied regularly according to manufacturers instructions, or after sweating or swimming.

Lastly, there are natural alternatives such as citronella oil and raspberry seed oil which will help keep pesky mosquitoes at bay while also protecting against harmful UV rays.
