Anyone ever been to Guam?

Boiga irregularis is harmless. Also kind of cute. They are technically venomous (rear fanged), but the envenomation experts who have intensively studied the species say that it's a non issue to humans.

I've worked with that genus a fair bit, though I prefer the more attractive and medically interesting species. They're fairly laid back and easy as pie to handle. And when they're not, mostly I don't care since a bite is inconsequential. It is somewhat annoying to get a faceful or a hand full of Boiga teeth, but really not that big a deal. It may bleed a bit freely as they have interesting components in their saliva as well as rather long teeth designed for arboreal hunting. Don't sweat about it; it's unlikely to get any worse than that. It is theoretically possible for you to have an allergic reaction (a type 1 hypersensitivity) just as with a wasp or bee sting, but that is a rare case, and unless that happens, the bite won't even be as bad as a wasp or bee sting.

The worst systemic effect anyone has ever reported from a Boiga bite is a headache and dry mouth, and that was from something much larger and more potent than the brown tree snake currently invading Guam. I am aware of the reports of one infant death and several infant injuries on Guam, but I just got back from an academic summit where those specific cases were laid out and discussed. The expert verdict was that it was not the venom that was the actual cause of death, but asphyxia. Whether this was caused by the snake is also questionable. The better questions to ask in the cases I saw discussed were, "why did the parents leave the infants outdoors and unattended for that length of time?"

Summary: those tree snakes = not much for humans to worry about, except that they have moved in and wrecked the indigenous wildlife. They're an ecological concern, not a human safety concern.
