Cockroaches in a sink

Cockroaches in a sink
Bedbugs on the floor
Ants in the microwave
Spiders on a door

Termites in the fridge
Bees in the showers
Mushrooms in the dryer
Mildew in the flowers

There isn’t any question
That there are house-pests everywhere
But what I want to know is
How did they end up there?

Bonus haiku:

long feelers waving
I poke my head out to see
only shining white
