Asian Tiger Mosquitoes Cause the Most Mosquito Bites in Virginia.
Every summer, thousands of Virginians complain to their local and state government officials about the horrible mosquito problems they have in their neighborhoods. Often, a nearby pond, puddle, flooded ditch, marsh or swamp are the focus of the mosquito complaint. However, in most cases the problem mosquitoes turn out to be Asian tiger mosquitoes and the source of these mosquitoes is found to be containers of water on or near the residence.
Asian tiger mosquitoes are only active during daylight hours [sun up through dusk], but do not like to spend too much time in open sunlight. Therefore, their populations are more of a problem in neighborhoods that have a lot of shade.
Asian tiger mosquitoes can be a potential health threat as they are able to transmit a number of mosquito-borne diseases. In Virginia, these diseases include West Nile virus, La Crosse encephalitis, and Eastern equine encephalitis. They could also be important vectors of tropical diseases like dengue and chikungunia if and when these diseases get imported into Virginia.
Unfortunately, control of Asian tiger mosquitoes by county mosquito control programs is difficult because the truck mounted foggers [aerosol sprayers] traditionally used for mosquito control only kill the mosquito species that are in active flight. As Asian tiger mosquitoes fly very little, and spend most of their time sitting in foliage, waiting for a meal to walk by, they are poorly controlled by such sprays. To have an impact, aerosol sprays would have to be directed with some velocity into all shrubberies and foliage from close range in each yard [i.e., by people with back-pack foggers].
The best tiger mosquito control efforts involve teams of people going house-to-house to find and dump, or treat all the container breeding habitats at each residence and to educate the residents. This activity can be combined with back-pack fogging or the application of barrier sprays (i.e., residual insecticides sprayed on bushes to prevent mosquitoes from landing or resting there). However, this type of control activity is generally too intensive and costly for most municipalities to afford, and if home owners are not educated or involved in the process, there are very few other control options available.
