lemon verbena help!

lemon verbena help!

I've had this indoor lemon verbena plant since September-ish, and it has recently been looking a little sad, loosing more leaves than usual and not looking as green. At first, I cast this aside because it's getting colder outside and thus colder inside. But I started to notice this weird spider web-like stuff underneath and around the leaves in the past couple weeks, and again ignored it because my apartment is old and thus very dusty. But now there are these strange reddish brown things! I googled bugs, figuring this is it, but I have no idea how to identify them. Does this even sound/look like a bug problem? Can I help it?? The plant is also sitting next to another plant (African violet), but the violet seems unaffected and is actually blooming again for the first time in a while. Should I be worried about "contagious" problems? Thank you!
