First mosquito pool tests positive for West Nile Virus in City of Boulder

The City of Boulder received notification today of the season’s first mosquito pool to test positive for West Nile Virus within city limits. The mosquito sample was pooled from three different traps that came from Tom Watson Park, Christensen Park and Stazio Ball Fields. The infected mosquitoes could have come from any of those sites, but it doesn’t necessarily mean that they are present at all three.

No human cases have been reported in Colorado so far this season; however, the city urges residents to take precautions to avoid mosquito bites and to drain standing water to prevent mosquito breeding sites.

Keep safe this summer and remember the four D’s:

1. Use insect repellent that contains DEET, picaridin, or oil of lemon eucalyptus.
2. DRESS in long sleeves and pants.
3. Avoid the outdoors from DUSK until DAWN.
4. DRAIN standing water outside your home.

Mosquito activity this year has been lower than usual so far due to the dry conditions. However, the type of mosquitoes that have the ability to transmit West Nile Virus have been present in greater percentages earlier in the season than in previous years.

City residents can help minimize the spread of West Nile Virus by eliminating any potential breeding grounds from around their properties:

• Clean gutters regularly.
• Change water in bird baths every three days.
• Check and empty any outside items that collect standing water (flower pots, lawn ornaments and toys).
• Do not overwater lawns.
• Keep trash cans covered and clean.
