What the City is doing

We are working with other City departments, neighborhood associations, community groups, and healthcare providers to distribute information to Philadelphia residents on how to prevent Zika and reduce mosquito problems in the city.


Throughout mosquito season, our staff sets mosquito traps all over the city to test if any of the mosquitoes are carrying diseases, and to see where we should work to reduce their numbers. We apply larvacide, a compound that keeps mosquito larvae from growing into adults, to more than 40,000 stormwater inlets.

Sometimes, if mosquitoes get bad enough in a particular area, we may spray mosquito pesticide to kill the fully grown mosquitoes. We only use pesticides approved by the Environmental Protection Agency (EPA) to fight mosquitoes. We do not use DDT.

Our routine mosquito trapping helps to track where Aedes albopictus mosquitoes are in the city and to prevent and reduce problems from this type of mosquito. Our monitoring will also let us know if Aedes aegypti, the mosquito causing the Zika outbreak, has moved into Philadelphia.


We work with area healthcare providers to identify and test Philadelphia residents who have or may have Zika, including women who are pregnant. Our staff investigate where and how these individuals were exposed to this infection.


Our Zika prevention efforts aim to educate residents who are most at risk for being exposed to Zika or could have complications of infection. These groups include:

  • Travelers
  • Pregnant women
  • Residents from countries that have Zika
