The City of Plano controls mosquitoes on public property by eliminating the breeding source, applying pesticides to stagnant water and spraying as necessary for adult mosquitoes. The Vector Control Program does not treat private property for insect (or rodent) problems.
You can help prevent the spread of illnesses caused by mosquitoes by remembering the four D’s:
- Dawn to Dusk - Mosquitoes are active most of the day. If possible, try to stay indoors. If this is not possible, make sure you follow the other D's.
- Dress in long sleeves and pants when outside to keep skin covered.
- DEET- This is an ingredient to look for in your insect repellent to apply when staying outdoors.
- Drain - Standing water is a breeding site for mosquitoes, drain the water in your yard. Keep swimming pools treated and circulated, and rain gutters unclogged.
A vector is an organism, such as a mosquito that carries disease-causing microorganisms from one host to another (vectors also include rats and other animals).
After an incubation period of 3 to 15 days, symptoms of the West Nile Virus often replicate the flu, beginning with headache, fever and body aches. Most infections are mild. Skin rash and swollen lymph glands may accompany these symptoms.
Severe infection is marked by headache, high fever, neck stiffness, disorientation, tremors, muscle weakness, paralysis, and rarely, death. Persons over 50 carry the highest risk for getting the disease.
A physician should be consulted immediately for any health concerns.
West Nile Virus spreads when mosquitoes feed on infected birds. The newly infected mosquito carries the potential to transmit West Nile Virus and may infect the humans or animals it feeds on. There is no documentation saying that West Nile Virus can be transmitted to people from either other humans or animals.
If you find a dead bird in your yard, it can be discarded in your trash receptacle. Avoid contact with your bare hands, place the bird into a plastic bag using either gloves or a plastic bag wrapped around your hands, then put the bird in your trash receptacle.
Other than birds, other animals that can be infected with West Nile Virus include:
Mosquitoes carry numerous diseases and parasites, which affect animals - heart-worm in dogs and equine encephalitis in horses being some examples.
West Nile Virus has been identified in horses, cats, chipmunks, bats, squirrels and domestic rabbits, but the vast majority of infections have been identified in birds.
Normal veterinarian care should be taken with any sick or injured pet.
The City of Plano Environmental Health Division does not administer immunizations (shots). Please contact your physician or Collin County Health Services at 972.548.5500 for information concerning immunizations.
Zika virus is an emerging mosquito-borne virus that was first identified in Uganda in 1947 in monkeys. It is spread by the bite of mosquitoes and was identified in humans in 1952. Outbreaks of Zika virus have been recorded in Africa, the Americas, Asia and the Pacific.

Texas has had a small number of confirmed cases of Zika virus disease. At this time, the only Zika activity in the United States is limited to traveler-imported cases and their sexual partners.
The City of Plano will spray for Zika after a confirmed case is reported from the Collin County Health Authority.
If Plano has a positive case of Zika, the Collin County Health Department will contact the City of Plano with follow-up information regarding the general location of the human case of Zika. The City will spray adulticide in the area of the positive case.
Although the Zika virus and West Nike Virus mosquitoes have different behaviors, the only major difference in our response will be the size of any spray area. Because the Zika mosquitoes have a short flight distance, the spray area for them will be less than that for West Nile Virus.
The products used by the City of Plano are safe when used in accordance with the directions. The City of Plano Environmental Health Division staff are licensed pesticide applicators and typically spray adulticide in the evening hours to limit the exposure to citizens.
The best way to protect people and pets is to limit exposure to the pesticides. It is recommended to bring pets inside to reduce their exposure.
