I have them too, on my white colored vinly siding. In the midwest, they come from the fields once the crops are harvested, thier natural habitat having been removed. I tried caulking around vents & pipes, which works to some degree. Also try adding weatherstripping along window screens, which often don’t fit tightly to the window frame. The best thing for me was spraying the exterior of my house & windows with a mix of cypermethrin insecticide (powder) & water. This is residual for weeks and may not appear to work instantly, but the number of dead bugs you will see outside is proof it works. What bugs do get in, will die shortly after since they passed through the insecticide on the way in. Also stopped beetles, flies, & spiders effectively (the dead bugs are the proof). You can buy cypermethrin powder from a licensed pest controller or online.
I find it interesting you said they dont like dark colored houses my house is filled with them and I live in a cedar home thats pretty dark and my walls are brown and red. I am sick of these things ahhhh!

I live in California and they are also coming into my room. For the past few weeks I have been taking them outside and putting them on our rose bushes, but they kept coming back. Now I just read this article and found out why they come inside my house. But, I would like to know if I should just leave them in my room and let them be or keep taking them outside every morning. I don't want to kill them and I don't mind them hibernating in my room. Just want to know what would be best for them. Please reply if you know what I should do. Thanks!
6. How can I get them out of my house? A. If you don't have a lot, just leave them. They will leave when spring arrives. Disturbing them will only cause them to stress out leaving yellow markings on your walls. The yellow stuff, you see, is not waste matter, but rather, their blood. Ladybugs release a small amount of their blood which is yellow and smells, when they sense danger. Some people have said that it does stain on light colored surfaces.
