-11 for the low here tonight, unfortunately we'd need several nights of -40 temps to kill off a lot of beetle.
I'm not a pine beetle expert by any stretch, but I think you mean -40 Celsius, instead of Fahrenheit?
Fingers crossed for a cold(ish) winter/spring to get the population in check.
Edit: Fun fact, -40*F and -40*C are the same thing. Mind blown! I guess -30 to -40*C, and -30*F, for more than five days, are the ticket. Huh.
yes, extremely cold weather in mid winter because the beetle metabolizes glycerol which acts as an anti freeze. It's better to have a cold spell that isn't as cold as -40 in spring or fall and that will kill them as well since they'll have less glycerol in their system.
fortunately they are pretty much non-existent down here in this part of the elks, but I imagine they mostly like lodgepoles which aren't as prevalent as they are in summit/grand counties.
