• Mosquito larvae may develop in virtually any shallow, non-flowing water.
• Aedes and Psorophora mosquitoes deposit “delayed-hatching” eggs in sites that previously held water such as wheel ruts, soil depressions, and woodland basins.
• These sites may be inundated by rainfall, snow melt or rainfall run-off.
• Large numbers of adult Aedes and Psorophora mosquitoes may emerge from these sites several days to a week or so after the eggs have been covered with water.
• Aedes and Psorophora mosquitoes inflict painful bites, but the most common species in Indiana typically do not transmit disease agents to humans.
• The very common Aedes species known as "floodwater mosquitoes" inflict painful bites.
• Floodwater mosquitoes can disperse many miles in suburban and urban areas.
• Disease carrying mosquitoes in the genus Culex may breed in the same sites if the water remains standing for several days or more.
• You have a higher chance of being bitten by Culex mosquitoes if you are outside from dusk to dawn when they are active and searching for a blood meal.
• To protect yourself from mosquito bites, avoid being outdoors at these times and wear an approved repellent. Fill in wheel ruts and other soil depressions to eliminate breeding sites.
