Lice?

Woke up this morning and had around 10 different insect bites, which is weird because I only had the odd one before. Where did they come from? How come I didn't hear them buzzing? Was starting to think it might be lice, but I washed my sheets last weekend and I shower every day. Even washed my hair today :). Hmmm, I'm gonna go with mosquitos for now. If only it wasn't itching so much!
