Curious what these tiny fellas are

Saw few of these guys crawling on our wooden floor. They are 3-4 mm long. Are they dangerous or bad for the wood or food?

Found this in Midwest

Who is this and how did it get in my apartment?

Live in an NYC highrise.

What is this bug?

Lots of these guys in my backyard and in my crepe myrtles, are they good or bad for plants?

Is this a fruit fly or a drain fly?

No matter how much i open the window, take my trash out, and clean my sink, these guys still somehow fly around my unit. Tried the vinegar and dishsoap trick they dont seem to really care for it. Tips on how to remove them would be appreciated!

Much bigger than an ant, probably about an inch long. It almost looks like it has fur on it that glistened in the sun

Silver small and quick bug on bed?

Took as good of a picture as I can, should I be super concerned?

What kind of spider is this? (Found in Michigan)
