I hate spiders myself, and have always feared going to take a vape and one crawling out of one of my Atty's into my mouth. With some liquids being sweet they could be attracted to them though the Nic would probably knock them out

but when you have a bunch of Mods sitting on a table over night it could happen, Yikes
This whole thread is funny, love the spider pix.
Just as an anecdote, whenever I set down open cartos, drip tips, etc, outside on a table somewhere where insects can get near it, I inevitably come back to a small circle of dead bugs surrounding it. OhMyGawd, sweet, awesome smelling, yummy, OD, drop dead, game over.
Nicotine is an excellent insect repellent/killer, it's still used quite commonly on organic vegetables ('cuz it's organic). The single downside being it is more expensive than other insect killer which is more commonly used.
If a spider crawled into your drip tip, and managed to come into contact with some juice, it really doesn't have a very long lifespan ahead.
