Mosquitoes in Las Vegas

Mosquitoes pose a greater threat to human health and existence than any other animal. Everyone knows they bite and that the result can be an itchy red welt, but certain species of mosquitoes can transmit some of the world’s most dangerous diseases. The most infamous one they spread is malaria, but there are many other dangerous diseases as well: Zika, West Nile, dengue, yellow fever, and more. Thankfully, only some species can transmit these. There are nearly 200 species of mosquitoes in the United States, and they inhabit several different regions. They also can adapt to a number of environments, from deserts to mountainous areas.

Mosquito Habitat

Mosquitoes need a source of standing or stagnant water to live and breed. This is why they are commonly found in marshes and lakes. However, they can also infest areas right here in the Las Vegas area. They only need a half-inch of water to survive, and can easily find it right in your backyard. Mosquitoes often harbor in kiddie pools, metal buckets, flower pots, and any object that collects rainwater or excess water from irrigation systems. This underscores the importance of homeowners regularly checking their property for containers that could be collecting water. In doing so, you can possibly avoid a mosquito problem.

Mosquito Behaviors, Threats, & Dangers

A mosquito bite can range from mild to very dangerous. Here’s what to know about their bites: 

  • Many species of mosquitoes require a blood meal before they can reproduce a batch of eggs.
  • Many people and animals are bitten by mosquitoes with no side effects except the typical itchy welt.
  • People infected with mosquito-transmitted viruses show no symptoms or only mild, flu-like symptoms that may not result in a visit to the doctor.
  • Severe symptoms following infection occur in a small percentage of people.

If you have a mosquito problem, it’s important to always enlist the help of your local mosquito exterminator.
