I don't know how to stay outdoors reliably without either (a) a break from the mosquitos or (b) willpower to influence my psychological and behavioral histamine response.

If I light a fire or candles that are smoky enough, the mosquitos will go away.  I'm not sure how to do that at this time.

They are also less prevalent in sunny, windy, or dry areas.  But they can still be around a little bit.
