SHB live in the darkness of the hive and when exposed to light they will run for cover and will crawl into an open cell. In a strong hive the bees will keep the SHB under control and prevent them from lying their eggs. When something happens to the nest, splitting, moving, taking honey, a storm, an animal attack etc the bees lose focus and let the beetles run. The female lays upwards of 600 eggs at a time and they will hatch in 24 to 30 hours. The larva then eat their way through the comb and poop as they go. This kills the larva and ruins the honey. The bees will not remain in the hive when infestation reaches a certain point, they will abscond. Putting your boxes on their side in the sunshine will cause the beetles to fly away, the larva will crawl to the edge and drop to the ground so you will not see anything in the boxes.
All bee hives have SHB living in them. You may not see them but they are there. I have seen SHB in the middle of swarms.
Wax moths have a slightly different body, the legs are different and the color is also. They to are nocturnal and they fly into the nest at night, lay their eggs and usually depart. The larva hatch and spin spider web-like strands behinf them. They to kill the bee larva and ruin the honey.
You can eliminate SHB by putting a black sticky board in the bottom of the hive and putting a Plexiglass cover on top of the hive. The Plexiglass allows light to penetrate the interior and drive the beetles to the bottom where they get stuck and die. This eliminates the wooden to cover and inner cover.
