We were called out to a termite inspection and bat estimate for a poorly maintained house. Our vertebrate technician, David Adragna, took these pictures (May 2016) of what might be the worst bat infestation we have seen.
Bat poop, or guano, littered the inside, piled high under the main beam of this A-frame house. Contractors sometimes fail to properly trim around the main beams, leaving gaps that bats can enter. Often woodpeckers damage well-trimmed houses, opening a space to store acorns, and consequently, allowing bats access to the space above the beams. The space above a main beam, and below the roof, makes an excellent roosting area.
You can see, from these photos, just how bad a bat infestation can get.

The Western Wood Cockroach, Parcoblatta americana, is a native California cockroach that lives outdoors. It can be found under rocks, and in and under old logs. This roach will sometimes be found inside homes, but this occurrence is mostly accidental, as western wood roaches do not live and breed in homes, as do the common household cockroaches.
The male, shown below, is a strong flier and is often attracted by lights. The female is wingless.
These next photos are of a small nymph, collected by David Katosic, in Wagner Ridge, Hells Hollow area, above Groveland, Tuolumne County California, May 7, 2018.
These photos were taken by Dave Adragna, approximately 31 May 2016. The flying squirrel appears to have been defending the entrance to a nest, located in the attic. Notice the chewed wood behind her.
