A squirrel was entering a house from a high and difficult-to-reach location, as you an see in these photos. It took quite some time to find this entry point.

In addition, structural damage from rot, woodpeckers, and the squirrel was severely impacting a structural support beam way up there. Photos by Jason Mink, 14 December 2016.

Here are some photos by Jason Mink of a chickaree exclusion setup, for a cabin in Camp Connell. That is a one-way valve in the center; it lets the Douglas squirrel out, but it cannot get back in. 12 December 2016.

This shrew was attracted to bacon in a rat trap and got caught, an unintended victim. Photo taken 10 December 2016, north of Sonora near Woods Creek, under a house.

Bats were entering near this chimney under a deck in Pine Mountain Lake, Groveland. Jason Mink installed this bat cone to let the bats get out. Later, he returned, removed the cone, and sealed up the entry area.
