An experiment gone horribly wrong

I've been doing a little experimenting in my basement with various types of insects. I've been trying to develop a "guard bug" for my property -- some sort of flying, attacking insect that would keep trespassers and door to door salesmen at bay. I figured by crossing a mosquito with a large predatory bird, such as a falcon or a hawk, I would ultimately end up with the quintessential attack/guard bug. My experiment worked -- or so I thought.

I have created a monster. The "Ratzquito" as I like to call it, turned out to be a bit too dangerous. I developed 14 Ratsquitos. I released them to safeguard my property and they immediately began divebombing and killing my animals, plus a few neighbors were lost in the process. I was forced to grab my shotgun and blast the creatures from the sky.

I killed them all... except one. The biggest, baddest, Ratzquito managed to escape. This creature is capable of reaching diving speeds of 120 mph and will kill you without hesitation.

The bug must be destroyed! If you see it, do your duty.

Our lives depend on it.

Here is what the Ratzquito looks like...
