Unwelcome Guests

The ides of war are upon me... since 3 months now, I'm waging a terrible war against a devilishly invader of my home. The dark brood Drosophila Melanogaster, also known as the common fruit fly.

Here is a photo of their common soldier:

Fear their evil gaze.....

This little siege of my home started 3 months ago when the clever villain of an insectoid smuggled it's eggs in an inconspicious tomato into my home. These little monsters have an infamous reproduction rate and over a night, I faced the first wave of their attack.
But I was ready to face this blatant assault of what is my hideout. Armed with swatter and vacuum cleaner I wrought havoc on these villanous wretches, the vacuum cleaner my frontline assault in my left hand, in my right, the swatter fighting down whatever escaped my onslaught. In a sucking which could only be described as an epic battle, a hundred unkempt members of their blackguard were smashed into oblivion.
But the plague did not stop with this... seeing their once strongly fortified foothold of my biologic wastebucket being crushed under the sucking power of my vacuum cleaner, clever agents went into hiding where I could not see them.
One week later, the black-brown scourge returned in all it's chitinous glory, for some reason taking a particular interest in the curtains of the room. While I can only guess what insidious mechanism they were planning to work from this, I decided ignorance is indeed bliss and vanquished their establishment once more with the aid of my trusty warhorse called vacuum cleaner, the swatter my glorious sword.
Yet, like the dog that didn't bark at night, the highly reproductive brown swarm keeps on reoccuring in regular pace out of nowhere it seems. After three months of wearing battle against the scourge, I've come up with a cunning yet distasteful weapon which can only be what the bomb was to Nagasaki. Under careful preparations I've gained access to a new tool of warfare. Named the project "Kärcher der Rächer", it will hopefully put an end to this reoccuring nightmare by vacuuming the places even my limited vacuum cleaner cannot reach.

It chills me to the bone thinking about their reproduction: These godless monsters, being reduced to a mere individuals every onslaught must have distasteful incestuous tendencies.
Furthermore, it are the words of old Darwin that add a certain despair to my situation.
"Survival of the fittest"... one can only lament about Darwin's Damokles sword over my head... I am certain it's only a matter of time till the ultimate superfly will evolve, horrors that certainly match the strange depictions of Dark Horse comic books.

To add a certain hint of bad humour to my situation:
I am studying Biology with aim on Genetics and Biochemistry. Drosophila Melanogaster is also known as the pet animal of the geneticists. Everybody who knows who Thomas Hunt Morgan was should know what I'm speaking of.
So whether this invasion here is a cruel joke of mother nature, a strange pointer of fate or merely coincidence is yet to be determined...
