Our Mission is to provide for the health, safety, and comfort of the residents within our district boundaries by the abatement of mosquitoes and other vector populations in order to minimize vector-borne diseases, The District accomplishes this task through constant surveillance and by employing the principles of integrated pest management in our efforts to control vector populations.


District Services

Our main concern is keeping vectors under control within District boundaries. We accomplish this by constant surveillance and applying whatever means are appropriate to eliminated sources. Another tool that is extremely important to us here at the District is our citizens calling to inform us of neglected pools, adult mosquito infestations, potential mosquito sources, or just to order mosquito fish for their ponds or animal watering containers. Please feel free to select the Service Requests tab above and fill in the appropriate information and we will respond as soon as possible.

AEDES AEGYPTI FOUND IN MADERA RANCHOS & PARKWOOD AREAS


Aedes Aegypti Mosquitoes

According to the Madera Mosquito and Vector Control District, the Aedes aegypti has been found in traps in Madera Ranchos & Parkwood areas in Madera County. Madera Ranchos is approximately half way between Madera & Clovis.

A few weeks ago, the yellow fever mosquito (Aedes aegypti) was identified in a several block area on the west side of the city of Madera. This aggressive day-biting mosquito is not native to California; however it is a common mosquito in urban areas of the southeastern United States.

The Madera County Mosquito and Vector Control District is working with the Madera County Department of Health to evaluate the extent of the infestation and will aggressively target problem areas to prevent its spread. “Our goal is to eradicate this population” said Leonard Irby, the District’s Manager. “We definitely do not want this mosquito to become established in our communities.”

The District continues to expand the search by going door-to-door in surrounding neighborhoods to undertake control measures including education, source reduction, larval control, and local ground-based adulticiding (fogging) as necessary to target adult mosquitoes. Fogging will begin immediately in the infestation area.

Unlike our most common mosquito species in Madera, this tiny (approx. ¼ inch) distinctive black and white mosquito is a very aggressive day-biter. While they may be active around dusk and dawn, it is their day-biting habits that are most characteristic. Aedes aegypti is an efficient vector (transmitter) of dengue, yellow fever, chikungunya, and several viruses that cause encephalitis.

Although the results for testing on the sample of Aedes aegypti found in traps are negative for dengue and chikungunya, the public is urged to take precaution by preventing mosquito bites.

“At this time, there is no need to consider vaccination for yellow fever, unless you plan to travel in an endemic area. Everyone should practice diligent mosquito control, because some mosquitos are vectors for other serious diseases such as West Nile Virus which is endemic to the San Joaquin Valley,” urged Dr. Thomas Cole, Health Officer for Madera County.

“Mosquito control is our best bet. Residents experiencing mosquito bites during the day are urged to report them to the Mosquito and Vector Control District. We need the public’s help on this one” urged Leonard Irby, District Manager. Everyone can do something”. Below are tips on mosquito control and avoiding bites:

Mosquito Control

- Check your yard weekly for water-filled containers.
- Throw away or recycle water-holding containers that are not needed.
- If empty containers or large objects, such as boats or old appliances must be stored, they should be covered, turned over or placed under a roof that does not allow them to fill with water.
- Clean and scrub bird baths and pet-watering dishes weekly and dump the water from overflow dishes under potted plants and flower pots. Check that gutters are not holding water and cover rain barrels with tight screening so that mosquitoes cannot enter.
- Fill tree holes and other cavities in plants with sand or soil.
- Check for hidden bodies of water such as wells, septic tanks, manholes, clogged drains, etc.
- Call the Mosquito & Vector Control District when you detect unusual numbers of mosquitoes.

Avoid mosquito bites…Use personal protection to avoid mosquito bites. Wear long sleeve shirts, long pants, socks and shoes when mosquitoes are most active, especially at dusk and dawn. Apply repellents such as DEET, picaridin, oil of lemon eucalyptus, or IR3535 only to exposed skin and/or clothing (as directed on the product label). Do not use repellents under clothing. In addition to wearing repellent, you can protect yourself and your family by using mosquito netting over infant carriers, cribs and strollers, and installing or repairing window and door screens to keep out mosquitoes.

Residents are urged to call or use the “Services Requests” tab (at the top) to report possible sightings.



***ATTENTION***

The Madera County Mosquito & Vector Control District would like to inform you that we will be fogging your neighborhood on Thursday June 27th, between the hours of 3:00am – 8:00am. Please note this is a new fogger that will be spraying a Larveside to skill and larvae that may be breeding in containers that we may have missed during our door to door searches. This unit uses a gas engine that is much noisier than our Adult Foggers but only needs to spray the area once to cover the mosquito larvae sources.

Attached is a Resident Survey that we would greatly appreciate you taking the time to fill out and return back to us. You may fax, mail or hand deliver to the number or address listed above.

Also if you have containers with water please remove the water or treat the containers with BTI pellets that can be purchased at a local hardware store, The District appreciates your help in the ongoing effort eliminating the Aedes Aegypti breeding sources in Madera.

If you have any question or concerns, call the District at (559) 662-8880.

Thank you!



PRESS RELEASE - YELLOW FEVER MOSQUITO FOUND IN MADERA CA. - June 17, 2013


Aedes Aegypti Mosquitoes

MOSQUITO INVASOR ENCONTRADO EN MADERA, CA - June 17, 2013


Aedes Aegypti Mosquitoes

El mosquito que causa la fiebre amarilla (Aedes aegypti) fue identificado esta semana en varias cuadras del área al lado oeste de la ciudad de Madera. Este agresivo mosquito pica durante el día y no es un nativo común de California; sin embargo es un mosquito muy común en las aéreas urbanas de los estados del sureste de los Estados Unidos.

El Distrito de Control para Mosquitos y Vectores en el Condado de Madera esta trabajando con el Departamento de Salud del Estado de California y el Departamento de Salud del Condado de Madera para evaluar lo extenso de la infestación y atacar el problema para prevenir su propagación. “Nuestra meta es erradicar esta población” dijo Leonard Irby, Gerente del Distrito. “Definitivamente no queremos que éste mosquitos se establezca en nuestras comunidades.”

El Distrito expandirá la búsqueda ésta semana e ira de puerta-en-puerta en vecindarios circunvecinos para tomar control y medidas incluyendo la educación, reducción de fuentes, control de larva y fumigación como sea necesario para contra atacar los mosquitos adultos. La fumigación iniciará inmediatamente en las áreas de infestación.

Es diferente a la especie de mosquitos mas comunes de nuestra área en Madera, éste pequeño mosquito de (aprox. ¼ de pulgada) se distingue de color negro y blanco, muy agresivo durante el día. Aunque pudieran ser activos alrededor de la mañana y tarde, su hábito es picar de día, es una de las características que lo distingue. Este mosquito conocido como: Aedes aegypti es un vector eficiente (transmisor) de dengue, fiebre amarilla, chikungunya, y varios virus que causan encefalitis.

Residentes que experimenten picaduras de mosquitos durante el día se les pide informar al Distrito. “Necesitamos la ayuda del publico en éste caso” dijo Irby. “Cualquier objeto aún el mas pequeño que retenga la mínima cantidad de agua deberá ser volcado y almacenado al revés. Por favor vigile su propiedad y deseche los envases innecesarios, botes, cubetas, y llantas (neumáticos), o colóquelas en la cochera. Este mosquito es aún conocido por poner sus huevos en agujeros llenos de agua en el asfalto y concreto.”

Evite las picaduras de mosquito! Use protección personal para evitar las picaduras de mosquitos. Use camisa de manga larga, pantalones largos, calcetines y zapatos cuando los mosquitos están más activos, especialmente por la mañana y por la tarde. Aplique repelentes tal como DEET, picaridin, aceite de limón eucalipto, o IR3535 solamente a piel expuesta y/o prendas de vestir (como instruye la etiqueta del producto). No use repelentes por debajo de la ropa. Además de usar repelentes, usted puede proteger a su familia, usando los pabellones para cubrir la cuna, carriolas y portabebés de sus niños, también instale o repare los mosquiteros de las puertas y ventanas para impedir la entrada de mosquitos.

Información sobre las medidas de control puede encontrarse en esta página web.

Se pide a los residentes a llamar o usar este enlace “Services Requests” para reportar posibles sitios.

The Mosquito Abatement District’s program is based upon scientific approaches that have been incorporated into a compre¬hensive strategy of Integrated Pest Management (IPM), an approach that includes the following components: larval site monitoring, biological control, and the careful and strategic use of U.S. Environmental Protection Agency labeled and registered pesticide products.


Mosquito Life Cycle



Mosquito deposit their eggs on the inside walls of containers such as fountains, buckets, tires, etc.



The district participates in the state wide surveillance system by maintaining two sentinel chicken flocks, testing dead wild birds, and by trapping mosquitoes for testing with CO2 baited traps. Combined, these give us a warning ahead of time each season about the activity of the virus.





The chickens are bled once every two weeks during the months of May through October. The chickens represent a critical element of the District's surveillance program and help to prevent any transmission of SLE, WEE and WNV to the human population.




The District operates an ongoing program throughout the year to monitor for the presence of mosquito borne viral activity. Whenever a virus is detected in a particular area, mosquito control procedures are intensified to reduce mosquito populations in order to reduce the potential risk for humans or animals contracting West Nile Virus.


CDC CO2 Trap New Jersey Light Trap Gravid Trap



Report dead birds on your property to The West Nile Virus and Dead Bird Hotline (877) 986-BIRD (2473) dead birds (crows, blue jays and raptors) can be the first indicators of the presence of West Nile Virus in the area.





You can protect your horse by having it vaccinated for WNV. The best time to have your horse vaccinated is early spring. Contact your veterinarian to get your horse vaccinated correctly.





A neglected pool has abundant organic matter or bacterial growth, often with leaves or other debris, resulting in green to blackish-colored water.




PROTECT YOURSELF FROM MOSQUITO BITES BY USING REPELLENTS!
Before you go outside, apply a repellent containing DEET

Mosquito Fish

Mosquito fish (Gambusia affinis)
Mosquito fish have brown-olive green backs, sometimes with silver grey yellow tinges, and silver bellies. Males average about 1 1/4 inches in length: females range from 1 to 2 1/2 inches in length. The species was described in 1854, and it's value to mosquito control recognized in the early 1900's. originally it was found in the southern United States, Mexico and Cuba. It has become spread through many parts of the world, and has adapted to many habitats, including cooler climates. Some strains can survive for short periods in shallow water under thin ice, but temperatures below 65 degrees F., and less than 14 hours of sunlight per day usually prevent reproduction. Mosquito fish bear live young in broods of 40 to 100 or more. Most females die after producing three or four broods. They nay drop all of their young in one season or part in the next. Mosquito fish have controlled mosquito larvae in rice fields when planted early in the season at the rate of 300 per acre. Efficiency can be increased by eliminating larger predator fish before planting mosquito fish, by providing water circulation and holding reservoirs, by deepening channels, and by controlling weeds.
Madera County Mosquito and Vector Control District stocks area permanent ponds with mosquito fish, and makes a concerted effort to stock semi-permanent bodies of water within the District's boundaries beginning in March and April of every year. The mosquito fish, proven to be efficient predator of mosquito larvae, has a wide range of temperature tolerance, and will thrive unless it's water is highly polluted. Since they have a high reproduction rate during summer months, a relatively small beginning population will build up fairly to whatever population level any given pond will support,
The District maintains holding ponds of mosquito fish for Madera County residents who want to stock their own ponds or watering troughs. Anyone wishing to pick up starter stock of mosquito fish should call our district a day in advance, bring a container preferably a 5 gallon bucket or large ice chest, and make arrangements to minimize the time fish are in transport.

Reporting Dead Birds

All dead bird pickups have to be routed thought the dead bird hot line. 1-877-968-2473 or Contact the California West Nile Hotline by clicking the Crow Picture below.

Information for controlling Other Vectors

Madera County Mosquito and Vector Control District is not funded to perform physical control of any vectors other than mosquitoes. The District can, however, act in advisory capacity for property owners and residents who wish to resolve other vector problems. These potential vectors include flies, fleas, ticks, spiders and rodents! etc. District personnel will supply information concerning biological cycles, habitat manipulation, exclusion methods, and potential pesticide application recommendations.

Neglected Swimming Pools

Dirty PoolPoorly maintained pools can provide a fertile breeding ground for mosquitoes, the prime culprit in spreading WNV. A significant percentage of mosquito complaints stem from neglected pools. Abandoned and neglected swimming pools have always been a problem, but now with West Nile Virus and Foreclosures nearing record levels ,it's extremely important to treat neglected pools as soon as possible.








Pre-spray Notification List

Madera Co. MVCD has a mandate and obligation to reduce adult mosquito populations in order to minimize the public's risk to mosquito-borne disease. All of the mosquito adulticides used by the district personnel are registered with, and approved for use in mosquito control programs by the California EPA, the California Department of Pesticide Regulation, and the California Department of Public Health. The District has and will continue to use mosquito adulticides as a last resort only, and in the lowest applications rates possible to achieve acceptable results. Most large-scale adulticide applications are performed in the early morning hours : between 3:00 and 5:00 A.M. Residential areas are avoided except in case of emergency involving immediate public risk to mosquito-borne disease.
However, if in spite of theses precautions, any resident remains concerned about the possible use of a pesticide in their area, a notification list is provided. When your name is added to this list you will be notified before any adulticiding is done in your immediate area, and advised of any possible precautions you might want to take. In some instances, your specific residence may be excluded from the spray area.
