I live only 20 miles from the nations's (America) hotspot for west nile. Along the same river downstream nonetheless! Mosquitoes lay eggs on water!!! I'm frightened because I've not been protevted from it, and I take long bike riodes down by the river where there are swarms of biting mosquitoes!! I've heard that it can kill you in most cases! Help! I already wear reppelant, but I've been bitten plenty of times.
