SCP-XXX {Bed Bugs}

In the title of the article, only refer to it as SCP-XXXX. The name 'Bed Bugs' would be used in on the mainlist entry. Also, since these aren't actually bed bugs, I'd find another name.

Elucid

'Euclid'

SCP-XXX-1 are

'SCP-XXXX-1 is' or 'Instances of SCP-XXXX-1 are'

initial layer of concrete, then a secondary layer of condensed limestone.

Give some measurements as to how thick each layer is supposed to be.

underground Site ██ In

'underneath Site ██. In'

they must sit in the chemical shower

Just sit there? Change the wording so they are actually being decontaminated.

These are the plants that instances of SCP-XXX-1 have been found in, but they show no preference in habitat.

This should be in the description.

activatable

'activated'

SCP-XXX-2 are

Same as before, either 'SCP-XXXX-2 is' or 'Instances of SCP-XXXX-2 are'.

smoke

What kind of smoke? Wood? Grass?

nullify

'sedate'

and SCP-XXX-2 refers to those contaminated with SCP-XXX-1.

This sentence doesn't work. Rewrite.

Ixodes pacificus

Scientific names should be italicized.

Typically done while the host is sleeping, SCP-XXX-1 will attach themselves to the host in a typical fashion.

This sentence is unnecessary. If the ticks exhibit the same behaviours as normal ticks, everything they do is typical.

pimples, warts, moles, [REDACTED], etc.

What kind of skin blemish needs to be redacted?

Once attached,

You've already stated what they do when they attach; this is what they do after they've camouflaged themselves.

sharp

This might just be me, but I don't like how this word is used. You don't have to, but I'd use a different word.

extensively pointed out to them.

What does this mean?

SCP-XXX-2 manifest

'Instances of SCP-XXXX-2 manifest'

take root in the brain stem

'attach to the brain stem'

it's

'its'

blood of any source.

'blood from any source' or 'blood of any kind'.

Through unknown means, the ticks become engorged with blood as their host consumes it.

I don't really see how this is unknown; that's what ticks do, get engorged with blood and all that.

SCP-XXX-2

'Instances of SCP-XXXX-2'

an unlivable degree,

I don't like how this is worded.

all of the instances

'all instances'

brain-stem

'brain stem'

they will still only

'they will only'

it's

'its'

The colony

The bush isn't the colony, the bush is the habitat.

12 year old Belle

These ticks don't seem grant the host any special powers. How is it that a 12-year-old managed to overpower and kill two adults? Also, you forgot the hyphens in '12-year-old'.
