CHICAGO (CBS) — You may have to start scratching in a month or so, but you don’t have to start worrying, as recent heavy rains and floods encourage the growth of flood water mosquitoes, reports WBBM’s John Cody.

State Public Health Spokesman Melany Arnold says it’s fairly standard: flood water mosquitoes flourish after floods and heavy spring rains.

“A lot of times with flood water we see mosquitoes that are nuisance mosquitoes but they generally do not carry any type of disease including West Nile Virus. So even though we are going to have a lot of flood water and we may see a lot of mosquitoes, they typically do not carry the disease.,” said Arnold.

Arnold says the real problem is the smaller culex mosquitoes which do carry West Nile and other diseases, but they need hot dry weather and stagnant weather before they become a problem.
