As summer rolls in, so does the swarm of mosquitoes that not only annoy us with their bites but also pose serious health hazards by spreading deadly diseases. Despite their commonality, many myths surround these pesky insects—some of which could put your health at risk.

Jim Fredericks, an entomologist and senior vice president at the National Pest Management Association, notes that misconceptions about mosquitoes range from silly to potentially dangerous. To keep you safe this season, we’ve teamed up with experts to debunk 14 common mosquito myths.

1. All Mosquitoes Bite Humans.

Not true! Only female mosquitoes bite to gather blood needed for their eggs—males feast on nectar like butterflies. If you get bitten, it’s almost always by a female.

2. Mosquitoes Are Drawn to Specific Blood Types.

While research has looked into blood type attraction, factors like body odor, skin bacteria, and carbon dioxide emission are far more influential. Body heat and sweat also play roles, making everyone a potential target.

3. Mosquitoes Can’t Bite Through Clothing.

Think again! Mosquitoes can penetrate thin or tight clothing, so opting for looser, tightly woven fabrics or insecticide-treated gear is your best bet.

4. Mosquitoes Only Bite at Night.

False! While many species are nocturnal, others bite during the day. Be especially cautious in shaded areas, as they can strike any time.

5. Mosquito Repellents Are Ineffective.

The right repellents—those EPA-approved—do work, but they need reapplying, especially after sweating. Don’t head out without it!

6. All Mosquitoes Transmit Diseases.

Not every mosquito is a health hazard. Many species don’t carry diseases, but it’s essential to be aware of the dangerous ones, especially those thriving in urban settings.

7. You’re Safe if You’re Not Near Water.

Think again! Mosquitoes only need a tiny bit of standing water to breed, like birdbaths or toys left outside. Keep your areas dry!

8. Natural Repellents Work Just Like Chemical Ones.

While some natural products can repel mosquitoes, their effects are short-lived. Rely on EPA-approved products for longer-lasting protection.

9. Garlic or Vitamin B1 Can Keep Mosquitoes Away.

Sorry, folks! There’s no solid proof that changing your diet will do the trick. Stick to specialized repellents for the best defense.

10. Mosquitoes Die After Biting.

Not at all! A single female mosquito can bite multiple hosts, increasing the chances of disease spread.

11. Not Feeling the Bite Means No Disease Transmission.

Wrong! Even if you don’t feel it, mosquitoes can transmit pathogens during their probing phase.

12. Backyard Treatments Will Eliminate All Mosquitoes.

These treatments reduce mosquitoes but don’t completely eradicate them. Continue to take precautions even after treatment.

13. Bats and Birds Control Mosquito Populations.

While it’s great to support wildlife, they don't significantly reduce mosquito numbers. Specialized pest control measures are a must.

14. Cold Winters Kill All Mosquitoes.

Not so! Some mosquito species hibernate or lay eggs that survive freezing temperatures, coming back strong in the spring.

Knowing these myths helps keep you informed and safe from these flying foes. This summer, don’t let misconceptions zap your fun—stay vigilant and enjoy the outdoors!
