I usually don't do much mole work in the winter months due to frozen ground and typically lack of activity. However, we've been seeing weather patterns shifting back-and-forth from cold to warm, and during the short warm-ups when the ground thaws, I may set a job or two for a couple days. All depends on the weather forecast. This pic is from yesterday while driving to a non-mole job.... but this is typical of winter mole damage here. Worms and beetles are deeper, so they have to excavate to feed. Soft, wet dirt allows them to move a bunch of soil. Damage is actually worse when there is a light frost, as they push up really large "chunks" of sod (kind of like breaking ice, but from the bottom up).
