Highland Park Asks Residents to Be Vigilant
In Highland Park, a pool on Beverly Drive, on the east part of town near the Katy Trail tested positive.
"The only thing I can say is we're getting into bulk of mosquito season here, probably related to the recent rainfall," city spokesman Lance Koppa said.
Residents received an email blast with an alert to watch out for pools of standing water in which mosquitoes can breed.
Only 20 percent of the Highland Park is public property, so homeowners must be vigilant, Koppa said.
"There has been an increase in folks calling us, and we welcome those phone calls because it's important we get out and inspect those areas that we may not be seeing," Koppa said.
Any problem areas on public property can be reported to the town on its website or by phone at 214-521-4161.
Highland Park also will provide a free backyard inspections for people who want their property checked for mosquito breeding grounds.
