Nuke'em from orbit, its the only way to make sure.

You have to introduce their natural Predators.

Attached are two photos, one of a xenomorph facehugger from Aliens wrapped around a plant pot with a succulent in it that appears to be mid-topple, the second photo is of the same facehugger apparently scurrying away from the same now-toppled pot.

A flamethrower will work and it is not a pesticide.

I thought this was real and the OOP was Australian. Took me far too long to get it.

They're actually harmless and keep your yard free of invasive species (like humans).

A crowbar might be surprisingly effective.

Nuke the site from orbit. It's the only way to be sure.

Just do it like you would do with a spider in your house: catch it alive, and set it free in an environment where it can thrive, e.g. Washington, D.C.

Have you considered running for your life, mate?

I just keep an orange tabby called Jonesy around to help with that

It’s just looking for a fresh face!

Game Over, Man. Game Over.

Flamethrowers seem to be the go-to solution if you don't want to use pesticides.

Nuke it from orbit, it's the only way to be sure

My gut feeling is to just face it or it will burst out of control.

OceanGate has a device that can kill a person faster than the brain can process what's going on. That should be humane.

is “hug therapy” not the way? that explains my family’s disappearance.

Fire. Lots of it.

Fire.

Lots of fire.

Shoot it

i olny have inhumane solutions

I'd recommend a pulse rifle, or flamethrower.

If you want to be sure, nuke it from orbit. It's the only way.

These are not pesticides, therefore within the limitations of the question.

Fire

They have acid blood, so I would suggest a strong base such as bleach.

Just move out, you have already lost the garden

Nothing an L56A3 Smartgun can’t handle. I always keep mine resting on the back porch ready for these pesky varmints.

Just walk around in the yard for a bit.
