Q: *What insect repellents should I use?* A: The Center for Disease Control (CDC) recommends adults wear repellent that contains 30 percent of the ingredient DEET to be most effective against the mosquitoes that carry WNV. However, lesser amounts of DEET products may be used with repeat applications during outdoor time periods as specified on the CDC website. Q: Can small children apply chemicals to their skin? What is recommended? A: The CDC states that precautions should be taken with insect repellent for children of certain ages. Parents with questions or concerns about repellents should consult their family physician.

A: As recommended by the Texas Department of State Health Services the City does not ship birds for testing. Birds are dead end hosts.
