Discussion Ideas
- According to Orkin, “June, July and August are prime mosquito months in most areas.” Why do you think summertime is mosquito-time?
- Temperatures rise in the summer and, according to AccuWeather, mosquitoes prefer warm, humid weather. (Although, the article points out, “You can actually get too hot and dry for mosquitoes to be active.”)
- According to our animal profile, “Most female mosquitoes lay their eggs . . . in water or near it.” AccuWeather dives a little deeper, reporting that “The key thing is that the water be still. Frequent rain can actually wash out the eggs, diminishing the chance for mosquitoes to become a problem. ‘Rarely do you have a problem in moving water,’” according to one scientist. What are some common types of wetlands where mosquitoes might thrive? Take a look at our short encyclopedic entry on wetlands for some help.

- Take a look at today’s MapMaker Interactive map of the biggest “mosquito cities” in the U.S. What are some large wetland areas in some of the most mosquito-prone areas? Use the zoom feature for some help.
- Atlanta: Chattahoochee River
- Chicago: Chicago River and Lake Michigan
- Washington, D.C.: Anacostia and Potomac Rivers
- Detroit: Detroit River, Lake St. Clair, Lake Erie
- Houston: Buffalo Bayou, Lake Houston, Galveston Bay
- Memphis: Mississippi River
- Minneapolis: Mississippi River
- Albany: Hudson River, Erie Canal
- Knoxville: Tennessee River
- Cleveland: Cuyahoga River, Lake Erie
- How was the list of the most “mosquito-prone” cities made?
- The rankings are based on data of where Orkin provided the most customers with mosquito treatments in 2014.
- What are some limitations of the list and the map?
- The list is based on data provided by a single company. It does not account for visits from local, independent pest-control businesses or other pest-control corporations.
- The list is based on the raw number of mosquito-related house calls. It does not account for an area’s population. Bigger cities may have more mosquito incidents, but a lower mosquito-incident rate than smaller cities, suburbs, or rural areas.
- How can you prevent or reduce mosquito bites this summer, wherever you are?
- Let the good folks at the EPA tell you!
- Apply an EPA-registered insect repellent. Here’s what to look for!
- Use a repellent safely and effectively.
- Tuck shirts into pants and pants into socks to cover gaps in your clothing where mosquitoes can get to your skin.
- Use head nets, long sleeves and long pants if you venture into areas with high mosquito populations, such as swamps and marshes.
- Stay indoors at sunrise, sunset and early in the evening when mosquitoes are most active, especially if there is a mosquito-borne disease warning in effect.
- Replace your outdoor lights with yellow “bug” lights, which tend to attract fewer mosquitoes than ordinary lights. The yellow lights are NOT repellents, however.
- Cover all gaps in walls, doors and windows to prevent mosquitoes from entering.
- Make sure window and door screens are “bug tight.”
- Completely cover baby carriers and beds with netting.
- Apply an EPA-registered insect repellent. Here’s what to look for!
- Orkin adds some more tips:
- Empty any standing water from bird baths, flower planters as well as toys and playground equipment outside the home to help prevent water from collecting.
- Clean gutters and downspouts regularly or cover them with mesh to help prevent leaves and debris from collecting and holding water.
- Let the good folks at the EPA tell you!
