Welcome to the Oregon Dormancy Tracker for the week of October 12, 2026. This week, we’re firmly in a dormant period across the entire state. Notably drier conditions than usual, with only 23mm of rain compared to 63mm last year, have significantly impacted breeding sites and kept overall bug pressure lower than normal, contributing to this widespread inactivity even before the recent cold snap. The plummeting temperatures mean that the typical concerns about Oregon bug bites are off the table, as most outdoor biting insects are inactive. This page serves as a weekly dormancy tracker, and the city and town notes below offer seasonal local information, focusing on frost, potential indoor pests, and next-season preparations, not bite forecasts. We diligently re-check temperatures every week and will restore full bite forecasts as soon as overnight lows and daytime highs consistently warm enough to support insect activity.
In Northwest Oregon, the average temperature hovers around 39.9°F, with overnight lows dipping to about 36.8°F. These sustained cold temperatures and the regular occurrence of frost have effectively halted mosquito activity, ensuring they remain inactive.
Northeast Oregon is also experiencing dormant conditions, with daytime temperatures averaging 38.3°F and overnight lows near 36.4°F. This consistent chill means black flies and other cold-sensitive insects are not active, offering a reprieve from their presence.
For Southwest Oregon, temperatures are colder still, averaging 37.0°F during the day and dropping to approximately 34.3°F overnight. These freezing conditions ensure that mosquitoes and most other outdoor biting insects are completely inactive.
Finally, Southeast Oregon is the coldest quadrant this week, with an average daytime temperature of 33.2°F and overnight lows near 31.6°F. These deep freezes mean all outdoor biting insect activity has ceased for the season. Remember that Just Bite Me temporary bug bite relief is still available at retailers across Oregon, perfect for any lingering indoor bites, upcoming travel, or to stock up for next season.

About This Forecast
This weekly update for Oregon uses current weather from OpenWeather. When daytime highs stay under about 10°C / 50°F (or nights drop near freezing), outdoor biting insects are treated as dormant and city notes switch to seasonal information instead of a bite forecast. Temperatures are re-checked every week so communities return to a full forecast as soon as they warm up. Store locations are sourced from Just Bite Me’s retailer database.
