You don't usually get bitten by mosquitoes on your neck though, how would this help with the bites you DO get all over your legs and arms? Or are you suggesting something so potent it absorbs into your bloodstream and then prevents bug bites? no thanks.

That’s what the medicated pet collars do.
Part of the advantage of collar-absorption is that you can use a molecule that readily breaks down/inactivates in digestion. And avoid sharp peaks in blood levels.

Not sure how true it is, but the marketing for the collars we use claims that eventually the chemicals spreads to protect the full body, even if the collar is just around the neck.
