What is this Bug?

Can anyone tell me what this bug is and how can I get rid of it?

I know I'm going to sound like such a girl right now, but I'm seriously freaking out about this bug and it's bug buddies that I keep finding in my bathroom.

Eww.... I'm sorry but I hate bugs and to have any in my home creeps me out. It makes me feel dirty and nasty.

I swear I am a clean person. I clean my house weekly, which includes scrubbing down my bathroom.  Yet, these icky and annoying bugs keep appearing in my shower.

Gross! It's so nasty. I typically drown them by picking them up with toilet paper and flushing them down the toilet. No way am I going to touch them with my bare hands.

What are these? AND... The most important question "How can I get rid of them?"

I want them out of my bathroom.

I typically find one maybe two in my bathtub/ shower floor. I'm assuming they are some sort of water bug. BUT why after all this time living in this house are they appearing?

In the past 8 years of living here, I've never had a problem with these bugs. However, within the last two weeks these creepy crawlers are appearing.

Yuck! I can't stand it and I want them gone. Even if that means setting off a bug bomb in my bathroom.

I absolutely HATE bugs!!!

Can anyone help a girl out?
