Another four mosquito pools tested positive for West Nile virus, bringing the city’s total to 20 for the 2024 season.

The gist

According to a Sept. 27 city news release, the four positives came from mosquito pools located at:

• Battle Creek Drive and Frisco Lakes Drive intersection
• Ottowa Ridge and River Trail intersection
• Along Shadybrook Lane
• Aragon Lane and Susana Lane intersection

In response to the positives, a third-party contractor was scheduled to spray the areas surrounding the identified mosquito pools with an adulticide overnight Sept. 28-29, according to the release. Adulticides are a mosquito-specific insecticide that target the adult mosquitos that could carry West Nile virus, according to the Centers for Disease Control and Prevention.



Spraying is harmless to pets and people when done correctly.

Something to note

Frisco tests mosquito pools for West Nile virus annually during the May 1-Nov. 15 mosquito season. Results from the city’s pool testing are then uploaded to Frisco’s mosquito surveillance map, a public database that has recorded all West Nile positives and spraying areas since 2018.

Going forward

The Texas Department of State Health Services recommends residents take precaution against mosquitos with the following steps:

• Wear: Wear long sleeves and pants outside at dawn and dusk when mosquitoes are most active.
• Apply: Use insect repellants if outside. Approved repellents contain DEET, picaridin or oil of lemon eucalyptus.
• Remove: Drain standing water that collects in bird baths, French drains, clogged gutters, saucers under potted plants and splash blocks. The mosquitoes that carry the virus can breed in stagnant water.
