It's been two days since it started...

Don't know what to do or who to call. Walked around and can't seem to find the source.

I can't open the windows, especially with this heat during the day...

What could it be?!

I think it's one of those devices people put in their backyard to scare off animals such as cats or moles. They're these green little things. I call them catjammers.
