Welcome to the heart of summer in Montana! As we head into the week of June 29, 2026, get ready for a significant increase in insect activity across the entire state, earning us a 🔴 High overall risk rating this week. Recent warm temperatures combined with lingering moisture from spring rains have created ideal breeding grounds, meaning our tiny, biting friends are more numerous and active than ever.
Up in Northwest Montana, you can expect warm, muggy conditions with some scattered showers, perfect for a surge in mosquito populations around the many lakes and rivers, alongside a continued presence of ticks in wooded trails.
Over in Northeast Montana, while temperatures will be heating up and conditions a bit drier, rivers and reservoirs will still be hotspots for hungry mosquitoes, especially during dawn and dusk hours.
For Southwest Montana, expect beautiful, warm days but be mindful that the numerous rivers and high-country trails are prime territory for prolific mosquito swarms, along with a consistent threat from ticks in the long grasses.
Finally, in Southeast Montana, warm and breezy conditions might offer a slight reprieve during the day, but come evening, the river bottoms and shaded areas will see significant mosquito activity. No matter where your adventures take you across Big Sky Country this week, remember that relief is at hand – Just Bite Me natural bug bite relief is readily available at retailers across Montana.
