Tiny vampires

The world's number one killers
They ought to be the subject
of those  horror movie thrillers
Gah, damn,  they could beat
even the serial killers!
Why no serials on these murderers?

Oh, they even get past locked doors
through the tiniest of holes and pores
And however tiny
they bode fatality
For to many their bites
have been lethal, fatal
And they sing freely in your ears
But like teeny weeny vampires
Dirges before even one died?

Don't you undermine the miniscule, the minute
For tis a real-life miniature vampire
Tis a blood sucking brute!

And they come in hordes
Without guns or swords
This major yet tiny killer of humans
Though you might kill it with a flick of your hand
Yet you could never wipe out the whole band
From the face of the earth
What with its prolific birth!
As this is one flying army here to stay
And by hook or by crook
In each and every nook
It shall share our land!

How terrible that our blood is on its main menu
My and your blood its main staple diet
So I warn you fellow humans
Save yourselves from the anopheles's bite.

Call it mosquito or agent of malaria
Plasmodiums are far worse than any bacteria

And they aren't just doing their job
They're doing their bloody feeding
We ain't in paradise yet:
thus both the harmful and harmless are breeding!

Don't let its invasive proboscis poke and probe you
Don't let it pilfer your blood
from your venue for its menu.
