Common eumenid wasps are beneficial, as they hunt oakworms, saving our oak trees from defoliation. But people still do not like them in their homes. Here is a video showing the wasps, unable to re-enter the wall voids, after we caulked the entry points. Each of these wasps is carrying an oakworm. The white caulk will dry clear.

Here is a film made from still images taken by a wildlife camera, placed to see what was living under this home in Mokelumne Hill, Calaveras County, California. It was a pair of pack rats. The one-way valve let the critters out, but they could not get back in. And they came back day after day, hour after hour, for over a week, to try and get back in. NOTE… the camera did not have the correct date set: the images were taken in December 2016.
We also see some local wildlife walk by: a raccoon, skunk, opossum, and something shy, elusive, and rare. Go to 3:02 in the video to see the one frame of the furtive creature. I shared the video with John Buckley of CSERC, an organization that uses a lot of similar cameras and is very familiar with the local wildlife. According to John, it “is almost certain to be a weasel…. it’s the right shape… right speed.” and “We only get them infrequently at our CSERC cameras, but they usually are rushing through the photo similarly.”
The weasel is likely there looking to eat those pack rats.
Here is some video from a drone we used to inspect a roof for squirrel entry points, in Arnold California, December 2016. The drone made a difficult job much easier.
This video shows David Muffoletto taking the Argo through swampy ground, and even through deep water. This unit allows us easy access to many, otherwise, difficult and un-reachable terrains. Video by Garrett Simpson, 30 November 2016.
This video taken by Ryder Richards in 2015, in Arnold California, shows pine tree ants, Liometopum luctuosum, in the ceiling of a house. You can hear the noise they make. It appears the ants excavated their way through the Celotex insulation, and the rift is in the egg storage area of the nest, as they are dropping eggs and larvae through the crack.
Here is a video of bats leaving to forage, from under the roof tiles of a home, taken by Michael Kelly, 15 September 2016, in Copperopolis California.
