The United States has approximately 200 documented species and Pennsylvania has around 60 species. Every year, diseases generated from Mosquitoes such as malaria, yellow fever, dengue and filarial worms kill or significant harm millions of people mostly in poverty-stricken countries. Mid-Atlantic West Nile Virus – In Pennsylvania, the risk of contracting a mosquitoborne disease has recently increased with the introduction of West Nile virus (WNV). Fortunately, West Nile virus poses little risk to most Pennsylvania unless they have comprised immune systems. Other Diseases – Other diseases of concern are eastern equine encephalitis and canine heartworm disease (dogs only). Canine heartworm disease is easily prevented and eastern equine encephalitis rarely is seen far from the Atlantic coast regions. Although, the chances of contracting a series mosquito-borne illness from mosquitoes are minimal, the summer of 2012 posed serious threats to Pennsylvania counties all over the state. Furthermore, there is much to be done to increase protection from the mosquito-borne diseases. How Do I Increase Protection? Reducing breeding locations is crucial, use of repellents, repair of home screens and the limitation of outdoor activities during prime breeding seasons when mosquitoes are less active. Mosquito Description – Adult mosquitoes are slender, small longlegged flies with narrow, hairy wings and extended mouthparts. The eggs, depending on species, are thrown on water or vegetation in water, in tree holes and other sites that hold a high potential for flooding. The northern house mosquito deposits its eggs on end and side by side (called rafts) on the water surface. Some mosquito species can complete their life cycles in as little as 7 days but the northern house mosquito requires a minimum of 10-14 days – more often closer to a month. The mosquito larvae are known as wrigglers because they wriggle around in water as a method of locomotion. When undisturbed, the wrigglers lie just below the water surface and breathe through a tube located on their abdominal end. West Nile Virus Disease Fact Sheet: Homeowner Tips – Below is a list of items the homeowner can do to help the process. Identification – Identify any areas that hold water and ask the homeowner to drain these items dry weekly. • Bird Baths • Children’s pools • Clogged Gutters • Toys • Potted plants • Bowls • Storm drains • Depressions on the ground • Tires • Anything that can hold water. Even a bottle cap could produce mosquitoes! Stagnant Water – Eliminate free-standing water around the property and lawn to reduce the volume of potential mosquito breeding sites. Ideally, this should be a community goal because most mosquitoes can fly long distances and can fly from property to property. The types of modifications include – With great communication and a solid control program the reduction of mosquitoes can be accomplished on a property. Recommend to the home or business, that the surrounding properties would also benefit from a Mosquito program. The more neighbors that are on a program, will greatly reduce mosquitoes from a general area. Exclusion – All doors and windows should fit tightly and remain closed during the peak mosquito activity periods between dusk and dawn. Screening should be no larger than 18 x 18 mesh. Replace screening that has holes or tears.
