Welcome to your Wyoming Bug Bite Forecast for the week of August 12, 2026! This week, we’re seeing a significant uptick in bug activity across the state, largely due to the somewhat wetter than usual conditions Wyoming has experienced, with approximately 39mm of rain helping to sustain higher mosquito numbers. This recent rainfall trend has created ideal breeding grounds, leading to a notably high overall risk for bug bites this week.
In Northwest Wyoming, expect a mix of warm sunshine and scattered showers, perfect conditions for a surge in mosquito populations, especially near standing water. Deer flies and horse flies will also be out in force, particularly in forested areas and near pastures.
Northeast Wyoming will experience mostly warm, dry days, but don’t let that fool you; the lingering moisture from previous weeks means mosquitoes are still very present. Look out for gnats near rivers and lakes, and an increase in yellow jacket activity as they forage for food.
Southwest Wyoming can anticipate generally clear skies and warm temperatures, making for pleasant days, but also prime time for biting insects. Mosquitoes will still be a concern in lower elevations, and we’re also forecasting an increase in no-see-ums around dusk and dawn.
Finally, Southeast Wyoming will see warm, sunny weather, which will keep mosquitoes active, particularly in damp areas. Ticks, especially dog ticks, will also be out and about, so remember to check yourselves and pets after spending time outdoors. For relief from those inevitable bites, remember that Just Bite Me temporary bug bite relief is available at retailers across Wyoming.
