"I got kids and I know that it's been going on a lot and I'm just worried about my kids", he said.
He has done some spraying of his own to keep the insects away.
"They have gone away. I haven't seen them much", Hernandez said.
Now he's getting some extra help in the way of aerial spraying. Lewisville is one of 31 cities in Denton County that chose spraying to fight mosquitoes carrying the virus.
Most of Lewisville was sprayed Friday night before the planes were forced to land because of the weather.
"The early morning hours we started getting heavy winds at which case we had to ground the operation at about 3:3. So we were able to accomplish about 80% of the spray block that we were hoping to get done which was about a quarter of a million acres", said Laura McGowan with Clarke Aviation.
Last week, health officials declared a health emergency due to the spike in West Nile cases.
Two people have died and more than 100 have been sickened by the virus.
Air crews are monitoring the winds hoping to get all the spraying done this weekend.
"We do have people down on the ground at all times making adjustments and giving forecasts as well as pilots that are actually using equipment that automatically adjust for wind speed and temperature", McGowan said.
Areas being sprayed Saturday night include, Southlake, Westlake, Roanoke, Trophy Club, Haslet, Farmers Branch and Lewisville.
If the weather holds up on Sunday, those same areas will be sprayed a second time.
