Mosquitoes/black flies in June in UP

Question

We are interested in a trip to pictured rocks national seashore in June, the question is : how bad are the black flies the first half of June

Answer

Visiting Pictured Rocks National Seashore in June is a fantastic choice, but it's important to be prepared for the potential presence of black flies and mosquitoes, especially during the first half of the month.

The first few weeks of June in the Upper Peninsula can be a bit tricky when it comes to biting insects. Black flies are usually most active during the late spring, and early June often coincides with peak black fly season in the area. These flies are particularly troublesome near water, and Pictured Rocks has many areas along the lakeshore and streams that can attract them.

Here’s what you can expect and how to prepare:

Black Flies: Black flies are usually most active in early June, especially in forested and damp areas. If you plan to hike near the lakeshore or through wooded trails, you’ll likely encounter them. They are most active during the daytime, especially in the early morning and late afternoon.
Mosquitoes: While mosquitoes are not usually as aggressive as black flies, they can still be prevalent, especially near water. They tend to be worse in the evening and at dawn, so it's a good idea to carry insect repellent if you plan to be outside during those times.
Weather Conditions: If it’s a particularly wet spring, you might find the insect activity to be even worse. Rain creates ideal breeding conditions for these pests, so it’s important to check the weather forecast before you go.
Protective Measures: To minimize discomfort, bring along insect repellent with DEET or other effective ingredients. Wearing long sleeves and pants can also help, though it can be a bit warm in early June. A lightweight, long-sleeved shirt and pants can protect you without overheating. Also, consider using head nets if you’re particularly sensitive to black flies.

While black flies can be a nuisance, they are usually not unbearable. Most visitors manage by being prepared with proper repellent and protective clothing. If you’re sensitive to bites or just want to avoid the worst of it, you might want to plan your outdoor activities for midday when the bugs tend to be less active.

In summary, black flies and mosquitoes are a concern in the early part of June in the UP, particularly in areas close to water. With some precautions, though, you should still be able to enjoy the natural beauty of Pictured Rocks without too much trouble from the insects.
