I was looking more in my bathroom and found this come out of a little crack underneath my sink… Basically throughout the years this little crack has given me lots of problems, I have gotten ants in my bathroom through there because the other side of the wall is the kitchen pantry and they come into my bathroom through that channel. I just found this little guy come out of there, looks different from the other two I just posted. Are these the same thing? What is it? Please help, I am so distraught I want to throw up.
