I found ladybugs in my spare room. Where did they come from and how do I get rid of them? Also what causes that?

Are you talking about lady bugs or Asian beetles? A big difference! You do not want to allow Asian beetles inside as they will take over by the hundreds! Buy an insecticide called "Bug Stop" and spray it around all your windows and sills at the first sign of them attacking your house in October. It will help the infestation and is residual for 9 months. These beetles will be out again in the spring and crawling all over your counters, windows, beds, etc.
To get rid of the ones inside: Double duct tape back on itself and touch the sticky side to the beetle. They cannot get loose and as long as their wings are stuck to the tape, they will not emit the terrible smell.
For those on the ceilings, have someone make a "T" shaped pole from some wood and attach the duct tape to the top of the T, again doubled back on itself so one side sticks to the pole and the top side is also sticky. Simply reach up with the pole and capture the bug.
Vacuuming is ugly, as they will smell each time the vac is turned on, plus they can crawl out of the wand.
The Asian beetles were imported by our government in the 1940's as a "natural" control for farmer's aphids on soy bean plants. However, there is no enemy of the beetles and they have multiplied by the millions and are traveling west. You are very lucky if you live in a large city where they are not prevalent due to no soy bean fields nearby.
Incidentally, they swarm to our homes, especially two story like ours, because in their natural habitat, they winter over in cliffs. Our homes are like cliffs to them.
They are not beneficial lady bugs. Do not let them loose outside once you catch them. Destroy them immediately. They will die on the duct tape or can be captured with a wet tissue and rolled up if duct tape is not handy. The wet tissue keeps them from emitting the terrible smell.
What people call the "Asian Beetle" is just a another type of ladybug, just one imported from Asia, actually a better aphid eater than our native species. They got into the attic before the weather got cold to wait out the cold and now with Spring arriving have gotten active and some are finding their way inside, probably through the ceiling light fixtures. Not a lot to do to stop them for this year.
You can apply a residual insecticide in the window sills that will kill them as they fly towards the light. Using the extension hose of the vacuum is the easiest way to catch and remove them. The release an odor that will ruin the vacuum so securing an old stocking on the hose will act as a filter keeping them out of the vacuum interior. In the summer try to seal and caulk area they can gain access into the walls and attic of the structure.
Treating the exterior of the home in late summer with a pyrethroid based insecticide will reduce their numbers trying to hibernate. (22 years doing pest control)
A black lite. It attracts them they get in the lite and it kills them. Be sure to check it often it will fill up fast. Just lay it down facing up. It works.
Lady Bugs are harmless. They come into the house in the fall through the tinest of openings to keep warm and hibernate for the winter. Just sweep them up and toss them outside or vacuum them up.
Ladybugs are beneficial to us. They feed on Aphids and other plant pests. I try not to kill them but it is annoying when they come into the house. I use my dustbuster to vacuum them up and then I take them outside and turn them loose.
