They do not breathe. They work more like the VBL Tom talked about. Water trapped between your hand and the glove acts as an insulating layer.
I got tired of trying different "waterproof" gloves and I can't stand bulky gloves.
I've used them in cold, windy, wet, and snowy weather down to...
These are yard trees in different locations. They are each the only Doug fir in the yard. They are stressed. One is in a hotel parking lot, so paved all around with cars driving over. One is up against a house, has a driveway on one side and just had a septic system installed near it. One...
I have three customers with infested mature Douglas fir. They seem to be only in the limbs so far. I dead-wooded them in the summer and now they have 3-8 more dead limbs each. I think cutting the dead limbs in early winter might get rid of some/most of the pupae.

About ten years ago the stem on the left was removed.
The stem on the right is periodically topped for power lines above.
Trimmed it away from the house and removed a limb over the house drop.
