I was combing my cat today, and I found three long bugs. They looked like fleas with tails. I set them down for inspection and they were gone. I looked around to see where they could have gone, and I niticed my arm at that very moment had three round drops of blood on it. I wiped it off. There were three holes in my arm. See photograph. I have seen a couple bugs with two round sections next to one another for the body and they have antennas. These bugs are like clear with brown stripes. I have also seen flat grey bugs that attach to your skin and  then turn black. They are attaching themselves to everything and making a mess of my home. My pest control company told me that I do not have bed bugs. I believe I have a few things going on here. There are also black dots everywhere and white dust-like things that have some sort of legs or prongs. Any help you can provide is greatly appreciated!
