When you think of the most dangerous creature in the world, you might think of a shark, a snake, a spider, or a lion. However, the real answer is none of these. The most dangerous creature in the world is actually a tiny insect that can transmit deadly diseases to humans and animals: the mosquito.

The Deadly Impact of Mosquitoes

According to the World Health Organization, mosquitoes are responsible for more than 700,000 deaths every year. They can carry and spread diseases like malaria, dengue fever, yellow fever, Zika virus, West Nile virus, and other illnesses that can cause severe sickness and death.

The Notorious Aedes Aegypti

One of the most well-known mosquitoes is the Aedes aegypti, also called the yellow fever mosquito. Originally from Africa, this mosquito has spread to many tropical and subtropical regions around the world, including parts of the United States. It is the main carrier of dengue fever, yellow fever, Zika virus, and chikungunya.

A Threat in Arizona

The Aedes aegypti mosquito is a seasonal visitor to Arizona, posing a serious threat to public health. It usually arrives in late spring or early summer when the temperatures rise, and the monsoon rains create perfect breeding conditions. This mosquito can survive in both urban and rural areas and can breed in any container that holds water, such as flower pots, tires, buckets, and bird baths.

Why is the Aedes Aegypti So Dangerous?

1. Aggressiveness and Adaptability:

  • The Aedes aegypti mosquito is very aggressive and adaptable. It can bite multiple times and feed on different hosts, which increases the chances of transmitting diseases. It can also adapt to different environments and climates and resist some insecticides.

2. Selectivity and Stealth:

  • This mosquito prefers to bite humans over other animals and is most active during the day when people are less likely to use repellents or wear protective clothing. It can bite indoors or outdoors and hide in dark, shady places like closets, under beds, and behind curtains.

3. Infectiousness:

  • The Aedes aegypti mosquito can carry and transmit multiple viruses at the same time, leading to co-infections that can make diagnosing and treating diseases more complicated. Some of the diseases it transmits can lead to serious complications like hemorrhagic fever, neurological disorders, birth defects, and death.

Preventing and Controlling the Aedes Aegypti

To prevent and control the Aedes aegypti mosquito, we need to eliminate its breeding sites and protect ourselves from its bites. Here are some tips:

1. Eliminate Standing Water:

  • Get rid of, drain, or cover any containers that can hold water, such as flower pots, tires, buckets, and bird baths. Change the water in pet bowls and fountains regularly. Clean gutters and downspouts to prevent clogging. Fix leaks and cracks in pipes and faucets.

2. Use Screens and Nets:

  • Install or repair screens on windows and doors to keep mosquitoes out. Use mosquito nets over beds, cribs, and strollers, especially for infants and children.

3. Wear Repellents and Protective Clothing:

  • Apply insect repellents containing DEET, picaridin, IR3535, or oil of lemon eucalyptus to exposed skin and clothing. Follow the label instructions and reapply as needed. Wear long-sleeved shirts, long pants, socks, and shoes when outdoors. Avoid wearing dark colors, perfumes, and colognes that can attract mosquitoes.

4. Seek Medical Attention:

  • If you develop symptoms of any of the diseases transmitted by the Aedes aegypti mosquito, such as fever, headache, rash, joint pain, or red eyes, see a doctor as soon as possible. Inform the doctor of your travel history and possible exposure to mosquitoes. Get tested and treated accordingly. Avoid further mosquito bites to prevent spreading the disease to others.


The Aedes aegypti mosquito is the most dangerous creature in the world and it will return to Arizona soon. It can cause deadly diseases that affect millions of people worldwide. We need to be aware of the risks and take action to prevent and control this mosquito. By doing so, we can protect ourselves, our families, and our communities from this tiny but deadly enemy.
