Red and Black Insect identification

Can anyone help me identify the insect pictured at the following link:

I've been seeing a lot of them in my home lately. We've been doing some
residing and installing new windows, so I'm wondering if their suddenly
showing up might be related. They are winged and fly around a little.

Thanks for any help.
