[pct-l] Mosquitoes

[Kea]

How bad really are the mosquitoes on a PCT thru' hike.  Yes, there will be
mosquitoes, and at times they will be in dense numbers.  But can one
quantify it?  Like how many nights/camps when complete coverage is necessary
compared to mosquitoes being a nuisance when one would simply brush them
away?  Or how often when camping is being outside of a netting enclosure
unbearable?

I don't remember seeing photos of hikers wearing netting suits and head-nets
when hiking or camping which tends to indicate that bad mosquitoes are
limited.

Does anyone carry bug-spray to clear our out the tent before retiring?

Thanks,
Kea
