various flies - Montezuma, Costa Rica

Flies! They poop on pies
They thrive in sties
They contaminate your lips while you're at rest
They dab the dung with spongy tongues
And pester your preserves with maggot nests.

Filth! Decay and spilth!
Roach and bedbug's tilth!
Fleas that suckyour juices in the night!
Maniples of weevils
The Moth and her coevals
Mosquitoes with their itchy-killy bites.

That gang is meat for fangs

Of allies prowling in and out of sight

The entire pack are treats and snacks

For spiders, giving bugs a deadly fright

Fear not when a spider appears

You may be tempted by the pesticide

But remember who is eating you

And let the spiders be. They’re on your side.
