had the Cockroach exterminator over

Cockroaches are by far and away, the hardest insect to exterminate.

For centuries, they've been smashed, bashed, mashed, crushed, trampled, and even... Stepped on.

And just when you've gotten rid of one, at least 10 more come to take it's place.

And no matter how many times you flush them down the toilet, they're crawling back up the bowl, drying off their wings and trekking across the lid.
