Nope!

Cool. He reads a lot, computer hidden in what appears to casual inspection to be a large hardback book without a title on it lest a title inspire conversationalists. Then he reconsiders and puts the title of one of the more interesting-looking demon-related books on the front.

Sunnydale is almost as quiet in the daytime as it is at night, at least until school gets out. 

Books agree on: vampires are evil demons. sunlight, holy water, stakes through the heart, and beheading all work; it's obvious if something works because the vampire will dust.  can't enter houses. faster and stronger than humans. existing vampires make new ones. no reflections. shifty fangy faces.

Books disagree on: whether crosses do anything, whether garlic does anything, whether fire does anything, what exactly is required for an existing vampire to make a new one, who can give a vampire permission to enter a house, how quickly vampires heal from injuries, whether vampires remember anything from the lives of the human whose corpse they inhabit.

Demons seem to come in astounding variety with astoundingly varied abilities.

This is fascinating and Cam will read about demons all day long, less occasional trips to the nearest trash can to discard cups and wrappers as he noms things. He checks his mail again come sundown.

Talon still doesn't want to say hi, apparently. 

Some demons are believed to be native to this dimension and many are from other dimensions. A lot of dimensions are called hell-dimensions; it's not clear what makes them hellish. Most demons are mindless beasts but some are believed to be intelligent. Many demons have magical powers ranging from telepathy to inducing hallucinations to teleporting to possessing people to inspiring terror and paranoia to excreting magical poisons to 'a good sense of direction' to both halves regenerating when cut in half. Some kinds of demon hybridize. There are several ways people can become demons - impressing a demon enough, doing an ascension ritual, being cursed. All demons are evil, of course, but some are very subtle about it.

Gosh. Rituals and curses. Anything on that sort of thing to be had?

Several of these are books about magic. There are all kinds. Some involve using magic ingredients to do reactions in a way that sounds like normal chemistry except that the ingredients are things like 'the horn of a Karrak demon' or 'the hand of a mummy' and the results things like 'makes people fall in love with you' and 'turns you invisible' and 'burns away your enemy starting with their little toe'. Some kinds involve prayers or negotiations with extradimensional deities. Some kinds use your inherent magical abilities, which people have varying amounts of. 

Do any of the potion-y things have exclusively nonmagical ingredients? (Where he's from mummies are nonmagical but he's not betting on that here. Can he make just a little bit of a Karrak demon horn?)

He can make some Karrak demon horn but it transpires that no potion-y thing have entirely ingredients he can make. 

Well, he supposes that might explain why none of these potions were invented back where things are as he's accustomed. What's the fastest way to determine if he has innate magical ability of the relevant sort?

He can check if he can levitate a sheet of paper; it might take a couple of days.

He will try this intermittently while continuing to read and sometimes check his mail. Sunset finds him still on this bench.

"You shouldn't be out," someone tells him, hurrying home with groceries, but they do not follow up on this. 

Some drunk college students or maybe teenagers meander down the sidewalk a couple hours after sundown on their way to a bar. 

Bars are less interesting than books. He is however becoming increasingly convinced that none of this is relevant to mosquitoes. He searches the corpus for various spellings and languages of "mosquito" and "malaria" (and other mosquito-borne illnesses) just to make sure.

Seems pretty irrelevant to mosquitos.

Cool, time to make a little shuttle and go put down some sterile male mosquitoes.

It's morning again by the time he's back and he resumes reading about demons and stuff. His shuttle is hidden under some shrubbery in the desert.

There's an angry letter from Talon.

Asshole. Now I can't eat at all.

...okay, where are her many tracking devices?

Like fifteen miles north of here.

Cam motorcycles on up.

He can get about fourteen miles, then the road is closed off. The sign says Bureau For Environmental Enforcement - Do Not Enter

He's gonna enter anyhow!

He gets maybe 200 feet before someone shouts 'freeze' through a loudspeaker.

Cam pauses and looks around.

"This is a secure area," the loudspeaker complains. "Put your hands on your head."
