With full protection (long sleeves/winter hiking pants/headnet/deet), I got about 50 bites.

I coated my clothes and exposed bits with deet and ended up with 75-100 bites.

Man, those are some damn persistent blood suckers. Even with chemical warfare!

Curious if these 3 posters had bites actually through their clothing (if so, what material?), or just on the minor areas of unprotected skin? The correct choice of fabrics can completely mitigate the former in my experience. I’m wondering just how bad things will be next week if I go in with optimal clothing system.

I got bites mostly on the unprotected skin, like fingers (8 on them!), face while eating, and areas that are in contact with tensioned fabrics (shoulders and knees). Some bites are under two layers of fabrics though. I would say it's possible to get it down to 10 bites per day if I'm careful enough with protection, and don't have to take care of my daughters. They are 4yo and 6yo, and I have to keep checking on their protection...

You need some industrial grade DEET. That was the standard for infantry troops in the Vietnam War.

Tableland 7/18-7/21

Route taken: Wolverton, Table Meadows, Tableland Pass, the two lakes above Big Bird Lake (WL 10435 T), traverse to the lakes north (WL 10402 T), back to Tableland Pass, along the ridge to the valley NE of Moose Lake, Moose Lake, N then down to Marble Fork Kaweah River near MILE 14 (W from hill 10251 T), and out.

There were just a few mosquitoes all the way to Table Meadows in some places (not all places) when stopped. Above Table Meadows (camped there) - mosquitoes become bothersome. This was unexpected, because I thought that snow has melted there recently. Almost no mosquitoes mid day on Tableland Pass and near lakes WL 10435 T. Bothersome mosquitoes on the traverse to lakes WL 10402 T and at these lakes (camped there). Also unexpected because I thought that that area has just thawed. Do they come from Deadman Canyon? Almost no mosquitoes on the way back from Tableland Pass to Moose Lake (camped just above it) and thereafter.

There was not much wind the whole time.

Agree 100% DEET. But more important is to abandon the dominant shorts and t-shirt hiking uniform so many wear. The key strategy during mosquito season is to cover up skin with clothing squeets cannot poke their probosci through. There are plenty of older threads where all that is discussed. See my inputs on page 2 at below link. I rarely have more than a few bites during even week long trips and those are almost always on hands/wrists while vulnerable working my camera gear after washing my hands that I do frequently leaving that skin unprotected.

Anyone been to Rock Creek Lake/Mosquito Flats/LLV lately can report on Skeeter situation? Trying to find somewhere to take the kids car camping, but my daughter often gets pretty intense reactions to insect bites.

just got back from Lamarck and Wonder lakes. Full on continuous 5 from start to finish. I suspect the whole Bishop Creek drainages are the same.
@rayfound , the ranger at Lee Vining and at Bishop both said that skeeters were in full force up and down the East side.

Thanks Jimr. Not exactly what I wanted to hear... but not very unexpected.

Interesting how this mosquito season has been unfolding later than normal due to the huge higher elevation snow pack. In the southern Sierra during June when mosquitoes usually peak they were surprisingly modest while now in late July when they usually are on the wane, they are peaking.

Much of our high country landscapes is glaciated bedrock granite where myriad shallow snow melting pools form. Hibernating snow mosquitoes rise up from lower mountain elevations when snow melts and daily freeze thaw cycles have ended. As snow melts at gradually higher elevations, mosquitoes follow into higher elevations to where such pools are common in order to lay eggs and create consecutive life cycles of increasing numbers. Most summers by the end of June, most such pools have dried up only leaving stream and lake edge corridors and lower elevation cooler forested slopes and meadows for breeding. Additionally the delayed rise of damselflies and dragonflies that voraciously eat squeets follows the migration but usually remain below timberline where winds are lower and mosquitoes are more likely to be flying about in the air they might eat.

However this summer high elevation pools above timberline will last well into August producing extra life cycles resulting in more mosquitoes than ever at many typical backpacking elevations.

On an 82 mile trip from Mount Hoffman through Clouds Rest, Merced Lake, Washburn Lake, Triple Peak Fork, up towards Isberg Pass, Lyell Fork and Vogelsang, the mosquitos were a 3 overall. The altitude didn't seem to matter,8000'-10,000,' only the amount of canopy overhead. We had plenty of Deet 98% that kept them at bay. Yes there were irritating but not a big deal. Thanks DEET!
