The worst killer on earth is making a comeback in the U.S.

FOX News Radio's Jill Nado explains:

(mosquito) The little mosquito has helped produce diseases that have killed more humans than all the wars in history combined. And the creeps are seeing a population explosion this summer in the U.S. There's been plenty of rain, so they've been breeding and that means more diseases like West Nile virus.

Conlon: "We're in for a bad time of it along about September time frame."

Joe Conlon of the American Mosquito Control Association also says we may be seeing more people suffering from Dengue Fever and then there's another real killer:

Conlon: "It's got a mortality rate of 60%. People die of Eastern Equine Encephalitis."

He warns you should get rid of standing water on your property and wear plenty of bug spray.
