Mosquitoes are the worst houseguests. They’re even ruder when you’re pregnant. You want to protect yourself and your baby from bites, which are annoying at best and dangerous at worst.

Why Are Mosquitoes Obsessed With Me Now?
If you feel like a walking bug buffet, you aren’t imagining it. Science confirms that mosquitoes find pregnant women irresistible.
In fact, pregnant women attract twice as many mosquitoes as non-pregnant people. Why? It comes down to two main factors:
- Carbon Dioxide: You take more breaths per minute when pregnant. Mosquitoes track targets by sensing CO2, so you are essentially sending up a brighter flare than everyone else.
- Body Heat: Mosquitoes have thermal sensors. Since your baby incubator is running hot (about 1.26 degrees F higher than average), you are easier to find (1).
Are Mosquito Bites Dangerous During Pregnancy?
For most people, a bite is just an itchy annoyance. However, the Centers for Disease Control and Prevention (CDC) warns that insect-borne diseases pose a higher threat during pregnancy.
The primary concern is the Zika virus (2). While rare in many areas, Zika can be devastated if contracted while expecting.
Zika can cause birth defects, specifically microcephaly (a smaller than normal head) and other developmental delays. Other illnesses, like West Nile Virus or Dengue, also pose risks to maternal health.
Which Repellents Are Safe for the Bump?
There is a lot of fear-mongering about chemicals, but the science is clear. Most EPA-registered repellents are safe when used as directed.
The CDC and the Environmental Protection Agency (EPA) recommend the following active ingredients for pregnant and breastfeeding women (3):
- DEET: The gold standard. Studies show it is safe for the fetus when applied to the skin. It does not accumulate in the body.
- Picaridin: A synthetic version of a pepper plant compound. It is odorless, non-greasy, and just as effective as DEET.
- IR3535: A common ingredient in Europe that is safe and effective for maternity use.
- Oil of Lemon Eucalyptus (OLE): This is the only plant-based ingredient recommended by the CDC. Note that this is a specific formulation (PMD), not just essential oil drops.
What To Avoid
Product Reviews
We looked for formulas that are effective, low-odor (for those sensitive noses), and easy to apply.
Sawyer Insect Repellent
Best Picaridin Repellent
The Sawyer Picaridin Insect Repellent is our top choice because it works as well as DEET but without the chemical smell or greasy feel.
It contains 20% Picaridin, which is highly effective against mosquitoes and ticks. Because it isn’t oil-based, it won’t ruin your synthetic maternity clothes or melt plastic gear (sunglasses, phone cases) like DEET can.
The pump spray is easy to control. We found it best to spritz it into our hands and rub it onto legs and arms to avoid inhaling the mist.
You get up to 12 hours of protection against mosquitoes, which covers you for a full day of backyard baby showers or evening walks.
Pros
- Virtually Odorless: Won’t trigger morning sickness or headaches.
- Material Safe: Safe for gear and clothing.
- Long Lasting: Provides up to 12 hours of coverage.
- Effective: Protects against Zika-carrying mosquitoes.
Cons
- Application: Pump spray takes longer to apply than an aerosol.
- Skin Reaction: Rare, but some users report mild irritation.

Superband Mosquito Repellent Bracelet
If You Want to Avoid Chemicals
If the idea of spraying anything on your skin makes you nervous, the Superband bracelet is a decent alternative. It is ideal for moms who want a zero-contact solution.
These bands are DEET-free and rely on a blend of geraniol, lemongrass, and citronella oils to confuse bugs. The smell is pleasant and citrusy, which is a nice change from the chemical odor of traditional sprays.
It’s incredibly convenient for short outings. You just slip it on your wrist or ankle. When you come inside, you take it off, no shower required to scrub off residue.
However, keep your expectations realistic. Wristbands generally only protect the area immediately around the band, not your whole body.
Pros
- No Mess: No sprays, lotions, or sticky residue.
- Reusable: Good for up to 200 hours if stored in the sealed bag.
- Adjustable: Fits swollen ankles easily.
Cons
- Limited Coverage: Does not protect your whole body like a spray.
- Potency: Not recommended for deep woods or high-risk Zika areas.

OFF! Deep Woods Repellent
Super Effective DEET Choice
OFF! Deep Woods is the heavy hitter. If you live in an area with aggressive mosquitoes or a high risk of disease, this is the safest bet for maximum protection.
It contains 25% DEET. While some moms worry about DEET, it is one of the most studied repellents in history and is considered safe for pregnancy by the CDC. It creates a vapor barrier that prevents insects from landing on you.
The aerosol can creates a fine mist that covers large areas quickly. It dries relatively fast, though it feels slightly heavier on the skin than Picaridin.
This formula repels mosquitoes, ticks, biting flies, gnats, and chiggers. It is the tactical choice for hiking or camping while expecting.
Pros
- Maximum Power: Contains 25% DEET for heavy-duty protection.
- Easy Application: Aerosol spray covers hard-to-reach spots.
- Dry Formula: Designed to be less greasy than lotions.
Cons
- Scent: Has that strong, classic bug spray smell.
- Residue: Can leave a white film or stain some fabrics.

Cutter All Family Insect Repellent
Best Scent
Cutter All Family is the “lite” version of bug spray. It is perfect for backyard BBQs where you want protection without smelling like you just came out of the jungle.
With 7% DEET, it is milder than Deep Woods but still effective for casual exposure. The formula includes soothing aloe and vitamin E, so it feels less harsh on sensitive stretching skin.
The pump spray works upside down, which is a lifesaver when you are trying to spray your ankles over a third-trimester bump.
Because the DEET concentration is lower, you will need to reapply this more often (about every 2 hours) compared to stronger formulas.
Pros
- Better Smell: Not as chemical-heavy as other DEET products.
- Skin Soothing: Contains aloe and vitamin E.
- 360 Spray: Works upside down for easy application.
Cons
- Reapplication: Wear time is shorter due to lower DEET content.
- Limited Pests: Primarily for mosquitoes, not great for ticks.

Greenerways Organic Insect Repellent
When You Want Mild, Natural Protection
For moms who want to keep their routine strictly organic, Greenerways is a USDA Organic option that uses essential oils to fight bugs.
The active ingredients include citronella, lemongrass, and cedarwood oil. It is lab-tested to repel mosquitoes, but keep in mind that “lab-tested” for essential oils usually means shorter duration than chemicals.
It is safe for use on skin and clothing, and because it is non-toxic, you don’t have to worry if your other kids or pets come into contact with it.
You will need to reapply this frequently, think every 60 to 90 minutes, to maintain a barrier. If you are diligent about reapplication, it’s a solid natural choice.
Pros
- Certified Organic: USDA Organic and non-GMO.
- Pleasant Scent: smells herbal and fresh.
- Family Safe: Great for use around toddlers and pets.
Cons
- Frequent Reapplication: Essential oils evaporate quickly.
- Oily Feel: Can feel a bit greasy on the skin.

Mosquito Repellents for Pregnancy FAQs
Do All Mosquitoes Carry Zika?
No, but specific species (like Aedes aegypti) do. It is impossible to tell which mosquito is which while it is flying around you, so it is best to be cautious in all warm climates.
What Smell Do Mosquitoes Hate the Most?
Mosquitoes are repelled by scents that mask CO2 or irritate their sensors, such as citronella, lemon eucalyptus, peppermint, and lavender. However, they don’t hate these smells enough to ignore a tasty meal if the scent wears off.
What Colors Do Mosquitoes Hate?
Mosquitoes are visual hunters and look for high-contrast targets. They are less attracted to light colors like white, beige, khaki, and pastels. Dark colors like black, navy, and red make you an easier target.
Is Citronella a Mosquito Repellent During Pregnancy?
Yes, Citronella is generally considered safe during pregnancy. However, its effectiveness is limited compared to DEET or Picaridin. It works best in candles or localized sprays for short periods.
Does Coconut Oil Repel Mosquitoes?
No, plain coconut oil does not repel mosquitoes. However, some studies suggest that fatty acids in coconut oil can be effective carriers for other active repellent ingredients.
What Natural Insect Repellent Is Safe During Pregnancy?
Oil of Lemon Eucalyptus (OLE) is the most effective natural option recommended by the CDC. Look for products registered with the EPA to ensure they have been tested for safety and efficacy.
Is DEET Safe to Use While Pregnant?
Yes. The CDC and EPA state that DEET is safe for pregnant and breastfeeding women when used as directed. It does not pose a risk to the fetus.
Can I Wear Sunscreen and Bug Spray Together?
Yes, but apply them in the right order. Put your sunscreen on first and let it dry. Apply the insect repellent second. This ensures the repellent stays on the surface where it can effectively ward off bugs.
The Bottom Line
Being a mosquito magnet is just one of the many joys of pregnancy, but you don’t have to suffer through the itch. We recommend Sawyer’s Premium Insect Repellent as the best overall choice.
It gives you the heavy-duty protection of chemicals without the nasty smell or greasy skin feel. Picaridin is safe, effective, and won’t ruin your maternity leggings.
If you are heading into deep woods or a high-risk Zika zone, don’t be afraid to reach for a DEET-based product like OFF! Deep Woods. The safety of you and your baby comes first, and preventing disease is key.
