Understanding the risks and preventing mosquitoes from breeding are the best and most practical means of keeping you and your family safe from mosquito-borne threats. Partner with the City to reduce the risk of West Nile Virus and protect yourself from mosquitoes.
City staff work in conjunction with the Tarrant County Public Health Department to battle mosquito borne diseases. As noted in the Mosquito Control Policy, managing mosquitoes takes an integrated approach outlined below:
The City of Mansfield is participating in the Surveillance/Testing Program in conjunction with the Tarrant County Health Department. Live mosquitoes will be captured with traps that can be moved to target locations throughout the City. The captured mosquitoes will be sent to the county laboratory for testing for the presence of West Nile Virus.
The City of Mansfield has ordinances covering tall grass and stagnant water. If you are concerned about an area being a breeding site, you may contact Public Works at 817-728-3340.
Maintenance of Public Areas
The City of Mansfield maintains major right-of-ways and public properties. We mow grass and will address standing water and place larvicide in these areas, as appropriate.
Mosquito Control Policy
The Mansfield City Council has adopted a Mosquito Control Policy that is based on 4 risk levels. The levels range from low, where no positive tests for mosquitoes have occurred for 3 years, to high, where a positive human case has been confirmed. Each level has a different response and City staff will vigilantly monitor any potential for an outbreak to ensure the safety of Mansfield residents. A copy of the Mosquito Control Policy can be downloaded here.

Mosquito control must be a shared responsibility in order for abatement to be successful. There are some things you need to do around your own home or business to reduce the mosquito population and eliminate their breeding sites. Take a survey of your own property to identify and eliminate the source of the mosquitoes. Here are several examples of things you can look for. Keep in mind that any source of standing or stagnant water can be a potential breeding location.
- Repair leaky plumbing, outdoor faucets, sprinklers, and septic systems.
- Change water in birdbaths, wading pools, pet dishes, and plant drip trays at least once every 2 days.
- Dispose of any items that may hold water and serve as a breeding ground for mosquitoes. These include old tires, buckets, unused plastic swimming pools, and other containers that can hold water. If they must be stored make sure they are covered or turned over to where water cannot collect in them.
- Remove leaves and debris from rain gutters. The leaves hold water in the gutter and are a prime breeding ground for mosquitoes.
- Keep grass cut short and shrubs well trimmed.
- Keep backyard swimming pools well cared for.
- Irrigate lawns carefully to prevent over watering which can cause water to stand for several days.
- Survey your property for areas that "hold" water and do not drain well.
- Stock ornamental ponds with mosquito eating fish.
- Remember that not all bodies of water are breeding ground for mosquitoes. Flowing creeks and waterways generally do not contain mosquito larvae.
- Use larvicide in areas of standing water. Bacillus thuringiensis israelenis (Bti) is a biological larvicide control used to treat areas of standing water. It is used to eliminate the mosquito larva but will not kill the adult mosquito. Bti comes in tablets or "donut" shaped discs and is available at most home improvement or feed stores. Citizens may actively treat areas of stagnant water on their own property, not to include creeks and other protected waterways.
There are some things you and your family can do for your own personal protection. To reduce the risk of getting bitten by mosquitoes remember the Four D's:
- DUSK to DAWN - is the timeframe when mosquitoes, likely to carry infection, are most active. Stay indoors from dusk to dawn.
- DRAIN - standing water in your yard and neighborhood. Old tires, flowerpots, clogged rain gutters, leaky pipes and faucets, birdbaths and wading pools can be breeding sites for mosquitoes.
- DRESS - in light colored long sleeves and pants when you are outside, especially in mosquito infested areas.
- DEET (N,N-diethyl-m-toluamide) - if you are going to be outside when mosquitoes are most active, make sure you apply insect repellant that contains DEET. Read and follow label instructions. Spray both exposed skin and clothing with repellent when outdoors.
Every mosquito bite does not cause West Nile Virus. Very few mosquitoes carry the virus and less than 1% of the bites that do have the virus actually cause serious illness. For more information on the West Nile Virus, you may visit the following sites:
