Who was in my bed last night

I found a centipede itentical to this one when I pulled the blankets off my bed last night. I smashed it with a can of Lysol and put it in a plastic bag. It can still wiggle half its legs, gross! I vacuumed my whole house before I went to bed. I found 2 of them on 2 occasions in the past couple of weeks in my kitchen sink, except they were green. They were all about 3 1/2 inches (8 1/2 cm) long. I did some research and found that they can crawl up drains. So, I will be keeping all of my drains sealed!
