CLIVE, Iowa - Bug experts say as the seasons change, the mosquitos carrying the West Nile virus are most active during the fall months.

The state’s entomologist, Robin Prusnier, says “continue to use your mosquito repellant don’t get lazy on that because you could run into trouble with West Nile more frequently this time of year.”

The wet and cool temperatures allow for more mosquitos to breed later into mosquito season. Data from Iowa State’s Department of Entomology shows a similar number of the bug last year at this time but Pruisner says often the public feels the mosquitos are worse than what the data shows, especially this year.

“Were not getting that natural break with a more typical dry end to a summer it keeps getting wet, we keep getting more mosquitos.”

Mosquitos typically began to die after the first hard freeze or when the temperature consistently stays below 50 degrees.
