What You Need To Know To Minimize The Risk Of Sustaining Bites From West Nile-Infected Mosquitoes

As many Arizona residents may have already learned, the west Nile virus is now a permanent component of southern Arizona’s ecosystem, making the diseased insects particularly prevalent around residential and urban areas of Phoenix and Tucson. Last May, state officials collected 87 mosquito specimens carrying the virus, which is up from a mere seven samples found in the same area of Phoenix last year. Unfortunately, the west Nile virus is not the only mosquito-borne disease to fear in Arizona, as officials also collected 53 specimens that were carrying St. Louis Encephalitis. This figure is up from only two cases of the disease found this time last year. The first west Nile disease case of the year in Arizona was confirmed last February in Maricopa county, and the mosquito season lasts from May through October in the state, so mosquito activity is not yet at its peak. In addition to this case, another west Nile disease case has likely infected a resident of Pima County. Needless to say, mosquito bites are of greater concern than ever before in Arizona. However, there are plenty of precautions that residents can take to prevent bites.

The west Nile virus is spread by the Aedes aegypti mosquito species, which is now abundant in southern Arizona. This particular mosquito species relies almost exclusively on standing water sources located in residential and urban areas in order to breed. Yards that contain an abundance of stagnant water sources will certainly see an abundance of mosquitoes. Removing standing water from residential yards will keep these mosquitoes away from human-populated areas and will also decrease the overall population size of the species. Even containers as small as a bottle cap can hold a sufficient amount of water for larval development. It is also important for residents to apply mosquito repellent before setting foot outdoors, especially when planning to remain outdoors for an extended period of time. The Centers for Disease Control and Prevention recommend using repellents that have been approved by the Environmental Protection Agency. Products that contain DEET and are designed to repel Aedes Aegypti mosquitoes are the most important aspects of an effective mosquito repellent.
