Successful Facehugger removal?

It tried to strangle Kane and tear his flesh when Ash so much as touched it's leg, and it secreted acid to get through his helmet.

How do you get around these defences even if you can stop the acid blood dissolving the needle you use to inject the base?

@S.M.

I stated earlier that a nuetralizing base could easily be injected into the face-hugger with a corrosive resistant needle  or dart. (many types of modern thermo-dynamic materials such as pecora mastic and PTFE are totally resistant to the effects of highly corrosive acids such as Sulphuric or Hydrocholric acid.)

Looking at the different Aliens movies, it ascertains that the face-huggers detect human presence at a certain distance (10 feet give or take..?) and release themselves from the eggs at that point. An individual can stand 50 feet away (or more if required),  fire a dart with the base agent into it and almost instantaneously, the acid is neutralized and the thermogenic increase in metal salts and water within its blood stream should kill the face-hugger...

Radiation could work but it's a risky move as it could also severely damage or even kill the host. 

The dart isn't a bad idea.

Assuming you have a plastic that won't dissolve in seconds (Alien acid eats through plastics just as well as metal).

And assuming you can fit enough base in the dart.

And assuming it doesn't kill the host while the base takes affect.

Getting rid of the facehugger is one thing but you must also stop it from laying the egg inside the human. I am not sure how long time it would take for it to lay an egg. Perhaps you could freeze the human and take out the egg later but I am not sure to take care of the monster.

That's the main reason I posted this forum.There isn't much of a point in removing it if you can't stop the embryo from being laid.

I hope this thread is still relevant now, although I am late to the party. Removing the facehugger is definitely one thing, but as observed in most of the franchise's games and movies by now, the embryo will still be laid regardless of the situation.

I know radiation is risky, but maybe if a chestburster was captured and experimented on with different types of radiation, perhaps the right one can be optimized to kill the baby from within. This kind of reminds me of how a radiation machine was used to kill a mind controlling parasite in Resident Evil 4 here:

Exhibit A

What about electricity? Sure, the host may become unconscious after a certain voltage is applied for a certain duration of time, but they are still able to recover from that damage given time to recover. Meanwhile, the premature chestburster in the host is more vulnerable to the effects of the shockwave, and if it doesn't die at first, it can still be safely surgically removed from the host to be disposed of in that way. I guess my thought process is kinda crazy, but I am kind of leaning more hope towards using the electric chair anyways.

Well, I haven't seen AC yet but I saw a trailer where a character just pull a hugger off lickety split lol!

The 'acid' involved, isn't acid. I checked with hubby some months ago, and we dug up the clip from the facehugger bleed, and figured out approx amount and speed of effect.

There's NO way a corrosive can act that fast vs alloys. Period, as it violates some thermodynamic principles.

HOWEVER, if it's an Oxygen-reactive substance that specifically attacks covalent and ionic bonds, THEN you have the same effects as seen on-screen...and in my story. ;)
Such a liquid would eat through literally anything, including teflon with equal ability and would only cease when it's ocidation-limit was reached.

This also explains why it doesn't consume the creatures from the inside, as it would need a second or two depending on temperature to activate, thus allowing bleeds to heal.

However, supercooling such a substance doesn't work as it's endothermic on a cascade level...one tiny reaction point and it starts heating up, thus driving it's own action via it's own heat.

Thus, not an acid, but a molecular-disassembler really, in liquid form. Base elements wouldn't work any better vs it than would teflon, glass, steel, etc..

Facehugger removal?
SPOILER WARNING:
Track the progress of implantation via MRI and when it's close, open the patient surgically, and 'catch' the egg capsule as it arrives, then let the facehugger detach and die normally thinking it's done it's job.

As a way of getting around it strangling the host?
Heart-Lung machine as used for surgery these days. ;)
