Wasp nest down a wall cavity
Updated: Jul 16, 2018
Not all wasp nests are obvious to see, though generally they are easier to find than bumble bees. This one is way down a narrow cavity. I love the challenge of finding those elusive nests that you know are not going to be successful when treated from the outside and the only way to avoid a call-back is to get stuck in and find the nest on the inside.
