Which Mosquito Species In Arizona Pose A Health Threat To Residents

Which Mosquito Species In Arizona Pose A Health Threat To Residents? And Which Species Can Become A Nuisance Within Homes In The State?

The United States is home to 150 mosquito species, more than 40 of which can be found in the state of Arizona. It may be hard for some residents to believe that so many mosquito species inhabit the state, but most of these species are completely absent from urban areas. Culex mosquitoes and floodwater mosquitoes are the two main categories of mosquito in Arizona, but the non-native aedes aegypti mosquito, which is responsible for the greatest number of mosquito-borne disease cases in the Americas, has also established a presence in urban and suburban areas in the state. There exists six mosquito pest species that pose a health threat to residents of Arizona, and some can even become a nuisance within homes and yards.

The six medically significant mosquito species that are present within populated areas of Arizona are western encephalitis mosquitoes, southern house mosquitoes, yellow fever mosquitoes, malaria mosquitoes, inland floodwater mosquitoes, and dark rice field mosquitoes. The southern house mosquito can be identified by a design on its abdomen that consists of five distinct lines. Not only are these mosquitoes a nuisance due to their large swarms and the loud buzzing noises that they produce, but they also pose a health threat to both humans and pets. This species is a vector for the west Nile virus and St. Louis encephalitis, and they can transmit nematodes that cause dog heartworm in pets and several encephalitis viruses in humans.

The inland floodwater mosquito is one of the most abundant mosquito species in the world and they cause more nuisance infestations than any other mosquito species. These mosquitoes are also notable for inflicting repeated bites and they can spread west Nile virus, western equine encephalitis, St. Louis encephalitis, and dog heartworm. The inland floodwater mosquito attacks humans in large swarms at dusk, and they can be recognized for the pale brown V-shaped design on their abdomen. These mosquitoes are particularly numerous in residential and urban areas of southern Arizona.

Have you ever been swarmed by mosquitoes while on your property?

A Few Mosquitoes In America Have Been Found Carrying A Rare And Deadly Virus

Given the copious amount of news coverage on the Zika outbreaks, as well as the aggressive public health campaign to convince people to take precautions against disease-carrying bugs, most Americans probably think that they are well aware of the diseases that mosquitoes can spread to humans. However, a recent finding in North Carolina will cause many people to think twice about this assumption. Researchers in North Carolina captured several mosquitoes that had been carrying a life threatening virus, but you have likely never heard of this particular mosquito-borne disease. The virus is known as Eastern Equine Encephalitis (EEE), and two cases have already been reported in one single county. The virus is a threat to both humans and horses. Luckily, no human cases of EEE have been reported in the United States this year, but one horse has already died as a result of sustaining a bite from a mosquito that had been carrying EEE.

In Onslow County, North Carolina, researchers have found more EEE-carrying mosquitoes. These mosquitoes can spread the devastating virus to humans and horses through one single bite. According to Pamela Brown, Community Relations Officer for the Onslow County Health Department, some people who contract EEE may show no symptoms, while others may develop flu-like symptoms, such as fever, chills, nausea, vomiting, and headaches. If you or anyone you know is experiencing these symptoms, then a visit to the doctor is in order. Those that contract the disease, but fail to seek medical attention, can rapidly develop more serious medical issues, including seizures, coma and sometimes death. Using repellent every time you step outdoors and being mindful of areas that contain standing water can prevent bites from infected mosquitoes. The CDC states that EEE is one of the most significant mosquito-borne diseases in the US. Thirty three percent of Americans who contract EEE die as a result of the virus. Most people who survive the disease will sustain serious brain damage as a result of brain swelling.

Had you ever heard of EEE? Does learning about this virus make you concerned for your safety this summer?

Mosquito Protection Tips | Magic Pest Control

Mosquito Protection Tips | Magic Pest Control

Many people may connect the height of mosquito season, occurring in the summer through early fall, to the irksomely itchy welts that accompany mosquito bites. But, there are far worse associations to make with these blood-sucking pests, such as the health threats they pose to humans in their daily lives—even in their own backyards. To help protect the community against mosquito-related health risks, Magic Pest Control is reminding the public about threatening mosquito-borne diseases as well as prevention tips to avoid bites.

Thanks to professional pest control there are certain serious, and sometimes even deadly, mosquito-transmitted illnesses, such as malaria, that we rarely see in the U.S. But, the public should remember that there are still harmful diseases including the Zika, West Nile and chikungunya viruses present in the U.S. that can be transmitted to humans by mosquitoes. In order to protect against these health threats, knowledge about each disease and general mosquito prevention is key.

The main ways to avoid mosquito bites and better protect against mosquito-transmitted diseases include:

  • Applying insect repellant containing DEET, picaridin, oil of lemon-eucalyptus or IR3535 when outdoors and use as directed on the product label. Apply repellant over top of sunscreen, and reapply every four to six hours.
  • Minimizing outside activity between dusk and dawn when mosquitoes are most active, though it is important to note that mosquitoes that transmit chikungunya are active throughout the day.
  • Wearing long pants, long-sleeved shirts and closed-toe shoes when outdoors.
  • Eliminating areas of standing water around the home including clogged gutters, birdbaths, flower pots, tires and kiddie pools or untreated pools. Mosquitoes need only half an inch of water to breed.
  • Screening windows and doors, and patching torn screens.
