Why Mosquitoes Thrive Near Lakes and Wetlands Around Superior

Summer near one of the Great Lakes is always a blast. Waterskiing, swimming, and other outdoor activities are fun for everyone, but the best times are often the ones in your very own backyard. The only problem is that sometimes, uninvited guests show up. Yes, we’re talking about mosquitoes—those pesky, biting pests that leave behind a nasty red welt that lasts for days. 

It seems like they show up as soon as the weather warms and are especially present in yards near water sources. Therefore, residents living around Superior and its surrounding lakes and wetlands often experience the worst of it. Finally, there’s a solution: mosquito control from Mosquito Squad Plus. But before we talk about it, let’s explain why Superior seems to produce more mosquitoes than in other regions. 

Why Do Mosquitoes Thrive Near Water?

Superior sits at the western tip of Lake Superior, surrounded by the St. Louis River estuary, Allouez Bay, and extensive wetlands. While these water features can be beautiful, they also create massive, uncontrollable mosquito-breeding habitats. This is because mosquitoes breed in water, needing as little as a capful. Combined with the lake-effect moisture that keeps humidity elevated and extends mosquito activity periods, it creates a compressed mosquito season in Wisconsin. This means from June through September, mosquito populations spike rapidly and peak intensely.

While mosquitoes by the lake can be nasty, wetland mosquito species are among the most aggressive. They emerge in large numbers after spring snowmelt and summer rains, which Wisconsin sees quite a bit of. Therefore, properties near the lakeshore, river, or wetland edges face the highest pressure.

What Can You Do to Help Limit Mosquitoes in Your Yard?

Unfortunately, individual homeowners can’t control the intense breeding that occurs in public waterways, which is where most of this problem originates. The only thing you can control is your own space, which is where professional yard treatment from Mosquito Squad Plus becomes especially important. 

However, there are a few steps you can take to help make your treatments go even further and help protect your family:

  • Be especially careful around dusk and dawn when mosquitoes are most active
  • If you go outside during these times, wear fuller-coverage, light-colored clothing
  • Remove any standing water from your yard, including playground equipment like tire swings, buckets, and watering cans
  • Keep your gutters clean and clear
  • Use fans on patios, as mosquitoes are weak fliers
