Storm Sewer and Catch Basin Treatment
The Medina County Health Department will begin mosquito prevention treatments in Medina County in May. This year, department staff will use Natular™ XRT, a larvicide product from the Clarke Company. It is an environmentally friendly larvicide which won the 2010 Presidential Green Chemistry Award. The tablets, which look like a large Pez candy (about 2 inches wide, 4 inches long, and ¾ inch thick), stay on the bottom of a catch basin for up to 180 days and will slowly release larvicide the entire summer.

Individual Public and Private Properties
The Medina County Health Department has treated numerous individual public and private properties. These are generally areas that have a nuisance wetlands, woodland pools, retention ponds, or abandoned swimming pools or spas.
Larvacides used on the individual public and private properties include Natular G and Mosquito Dunks.
Natular G is a Naturalyte product for killing mosquito and midge larvae. This products active ingredient, spinosad, is basically derived from the fermentation of Saccharopolyspora spinosa, a naturally occurring soil organism.
Mosquito Dunks, is a biological insecticide that prevents mosquitoes from hatching, which can be used in aquatic habitats. This products active ingredient is Bacillus thuringiensis (Bti) a naturally occurring soil bacteria.

How to Protect Yourself and Your Family
Facts About West Nile Virus
West Nile virus is a mosquito-borne virus that can cause encephalitis (inflammation of the brain) or meningitis (inflammation of the lining of the brain and spinal cord).
West Nile virus is spread to humans, birds, and animals by the bite of an infected mosquito. When a mosquito bites a bird that carries the virus, the mosquito becomes infected.
Many birds can be infected with West Nile virus, but crows and blue jays are most likely to die from the infection.
You will not necessarily become ill if bitten by an infected mosquito since most people who are infected with West Nile virus either have no symptoms or experience mild illness. If illness were to occur, it would occur within 5 to 15 days of being bitten by an infected mosquito. People cannot get West Nile virus directly from another person who has the disease. West Nile virus is not spread by person-to-person contact such as touching, kissing, or caring for someone who is infected.
The mosquitoes that carry West Nile virus typically lay their eggs in stagnant water and water-holding containers. Weeds, tall grass, and shrubbery provide an outdoor harborage for adult mosquitoes.
You can reduce the number of mosquitoes around your home and neighborhood by eliminating places
where they lay their eggs. Here are some simple steps you can take:
Dispose of tin cans, plastic containers, ceramic pots, or similar water-holding containers that have accumulated on your property. Dont overlook containers that have become overgrown by vegetation.
Clean up any solid waste and scrap tires on your property. Stagnant water in discarded tires is an ideal site for mosquitoes to breed.
Turn over plastic wading pools and wheelbarrows when not in use.
Clean birdbaths weekly.
Drill holes in the bottom of recycling containers left outdoors and in tires used for swings, barriers, running exercises, etc., so they wont hold water.
Clean clogged roof gutters every year. Roof gutters can produce millions of mosquitoes each season.
Aerate ornamental pools or stock them with fish. Water gardens become mosquito producers if they are allowed to stagnate. Clean and chlorinate swimming pools that are not being used. Mosquitoes can even breed in the water that collects on swimming pool and hot tub covers.
Use landscaping to eliminate standing water that collects on your property. Mosquitoes will develop in any puddle that last for more than four days.
Childrens toys and tarps covering wood, cars, boats, and other equipment can also hold water and breed disease-carrying mosquitoes.
The best way to protect yourself is to avoid being bitten by mosquitoes.
Use personal protection while outdoors when mosquitoes are present.
To reduce your chances of being bitten by mosquitoes:
Wear light colored clothing, long-sleeved shirts or jackets and long slacks.
Use mosquito netting when sleeping outdoors or in an unscreened structure. Protect small children when outdoors.
Avoid mosquito-infested areas or stay indoors when mosquitoes are most active (Many mosquitoes are most active two to three hours before and after dusk and again at dawn when the air is calm. This is the time when the females are most likely to bite. However, some species will feed at any time of the day.)
Avoid physical exertion, and use colognes and perfumes sparingly as these may attract mosquitoes.
Consider the use of a mosquito repellant, according to directions, that contains DEET (not to exceed 30% for adults and 15% for children) when it is necessary to be outdoors.
Put size 16 mesh screens on all doors and windows and keep them in good repair.
Dogs, Cats, and Horses
West Nile virus is not considered a major risk to dogs and cats. Only a few have been reported with the virus. Clinical signs of West Nile virus infection in horses include: listlessness, stumbling, lack of coordination, partial paralysis and death. Horses can be protected by vaccination.
MEDINA COUNTY HEALTH DEPARTMENT
MOSQUITO CONTROL PROGRAM
The Health Department conducts a yearly county-wide mosquito control program. The program includes: public education on mosquitoes, West Nile virus, and protection measures; and application of a bacterial larvacide to control mosquito larvae in storm water catch basins, roadside ditches, and other standing water areas. The Health Department does not conduct spraying for adult mosquitoes. Local communities that have had past spraying programs may continue to provide this activity.
Road Ditch Treatment
The Medina County Health Department treats standing water in road ditches in residential areas throughout the county. A global positioning system (GPS) is used to record and locate road ditches with poor drainage.
The larvacide used for road ditch treatment is VectoLex WDG, a biological insecticide that prevents mosquitoes from hatching while preserving mosquito-eating wildlife. The active ingredient in VectoLex is the naturally occurring spore-forming bacteria, Bacillus sphaericus (Bs).
