Recent news reports tell us that two Maryland residents have been diagnosed with West Nile Virus this year. Check out the report on My Fox DC here. Some reports have said that the Asian Tiger mosquito, perhaps the most prevalent mosquito in Frederick County, MD, is not a threat to transmit West Nile Virus. However, the University of Maryland extension has reported that the Asian Tiger mosquito is a threat to transmit West Nile Virus to humans. In a Gardeners’ Alert the University of Maryland explains that “The Virus is distributed by birds infected by Asian Tiger mosquito bites. Although mainly a bird disease, West Nile Virus afflicts birds, horses, and humans as well. Crows are particularly susceptible to West Nile Virus. However, the Virus has been detected in other wild birds, other mosquito species, humans, and horses.”
Another interesting tidbit from the article:
“The West Nile virus can be transmitted by mosquito species other than the Asian Tiger. However, the all-day feeding habits of the Asian Tiger mosquito may increase the risk of spreading West Nile virus. The Maryland mosquito spraying program is not the best against the Asian Tiger mosquito. Spraying is usually done at sunset or after dark for native mosquitoes. Asian Tiger mosquitoes are virtually absent during these hours.” Mosquito Squad’s treatments use a different product than that used by the state. The product Mosquito Squad uses has a residual affect that will kill mosquitoes that come onto the treated area, while still being people and pet friendly. This has resulted in much better control of the Asian Tiger mosquito in many yards around Frederick.
