2025 Mosquito Reports

[maverick]

Use the following scale to report the severity of the mozzies you experience:

0 - No mosquitoes

1 - They were present but not biting yet

2 - Very light during the day, moderate at dawn and dusk

3 - Moderate during the day, heavy at dawn and dusk

4 - Heavy during the day, heavy at dawn and dusk

5 - Unbearable all day, no breaks, cannot eat outside the tent. If you stop, hundreds will descend on you; looking through a camera viewfinder, you see more skeeters than a lake. If you slapped your arm, you'd smear blood from all the dead gorged bodies.

Please do not post questions or ask about a particular area in this thread; any off-topic comments will be deleted.

Please include where you went, with dates included, in the "Subject" box. Thanks

horseshoe meadows, mulkey meadows, templeton meadows, kern peak, golden trout creek, Rocky basin lakes, boreal plateau, siberian outpost, tunnel meadow ; 0-2 going in, some areas 3 on the way out. Oddly not that much difference between dawn/dusk and midday. They were worst along Golden trout creek and South Fork of the Kern.
