Thanks for that report wildhiker as that confirms further north how the recent cold days killed dead a whole early generation of mosquitoes that likely had been above freezing elevations.

Please make sure, that you update the "subject tab", with the location and dates of your trip, it saves us time from having to go back and change them. :) Thanks

I don't give out specific route information, my belief is that it takes away from the whole adventure spirit of a trip, if you need every inch planned out, you'll have to get that from someone else.

Horsethief Canyon dayhike, June 21, 2017

Post by scraperpro »

Sighted only one mosquito early in the morning at the trailhead parking lot, otherwise none. So: level 1

Only occasional patches of snow above 8000'.

Desolation Wilderness - Loon Lake & Rubicon River

Post by Quercus23 »

Just got back from a quick trip out to Rubicon River area, Desolation Wilderness. Mosquitos 0-1, maybe 1+ in swampy bits and along shoreline of Rockbound & Rubicon (elev. 6,500). None higher up.

Copper Creek 6/24 / Mist Falls 6/25

Post by tlnagy »

Hiked up copper creek in SEKI (6/24) and the bugs weren't too bad, probably a 2.

Also did a short day hike up to Mist Falls (6/25) in Lower Paradise Valley and that was awful; probably a 4-5. We had to keep constantly moving throughout all wooded areas and you could see a cloud of mosquitoes following you. Lots of standing water from flooding everywhere still so this will likely continue for the next couple weeks.

6/30 Blue Lakes Rd/Markleeville Peak Charity Valley

Post by SNOOOOW »

I guess the bugs are always bad out on Blue Lakes Rd but I have only been out there in the Fall so they never were bad for me. However, on June 30th the bugs were about a 5-6 I would say. I was getting bitten up until I got up on the ridge and the wind kicked in...Without the wind I was always swatting mosquitoes

North Fork Big Pine 7/2 - 7/3

Post by Midnight Sun »

Above Lon Chaney's cabin mosquitoes were a 3. 4 in some wooded areas near the lakes. Some reprieve in the more exposed areas with slight breezes. ~20 bites over a couple days. Don't go without some kind of defense.

Castle Pass - Peter Grubb Hut (PCT) 7/3 - 7/4

Post by thirdbestfriend »

Most of the trails are still covered in snow, although Castle Pass itself is dry. With lots of runoff and few standing pools just yet, mosquito activity was a 1-2. No bites, we saw a few at the trail head off I-80 and sprayed our clothes to keep them away. Then, nothing the rest of the weekend.

I estimate the snow will be off the trails by mid-July, so you may have just a short window to hike there and enjoy the scenery without getting attacked.
