[Marvel] What would be the easiest way(s) to kill Carnage and Venom?

They're "weak" to fire and sound, but it's (as far as I know) shown that their comic counterparts can often shrug those off relatively easily. So how can you kill them?

And, even more importantly, what's the easiest way of doing so?

There's a pheromone that repels symbiotes and prevents them from attaching to their hosts. Assuming they're willing and able to kill the host, anyone wearing it could do so to either symbiote.

Of course, said pheromone is only available in the future in another dimension (Earth-8009) so "easiest" is relative. Women there are genetically engineered to emit this pheromone, to keep back what they call "the Black Bloom."
