Aragog vs Orkin

Ron and Harry stood before the massive spider and despite his best efforts, Harry was losing his nerve and resolve to stay. Ron kept pestering for him to leave but Harry had a better idea, albeit one that was a nightmare for all involved, just not him. Ron could see that the spiders were inching closer, their hairy legs within a hairs breadth of touching him. Ron let out a shrill screech and took off running, with half the forest on his ass. Harry calmly took out his wand.

Aronia Exumai

one by one, spiders went flying as Harry made a mad dash towards the safety of the school. He barely managed to close and bolt the doors, just in time to see Aragog charging the doors. They did not break, thanks to years of magical repairs and improvements. One of these improvements was a hidden vat of boiling oil. One unlucky spider learned this the hard way and, when his friend tried to put it out with Gasoline, He screamed and set half the forest on fire, looking for water while howling in agony. He did not make it and was used as BBQ by the centaurs.

Harry peered out the window, they were watching his movements and Ron was still out in the forest. Harry felt for his friend but there were more pressing concerns. The relatives of said spider were looking into his window, intent on murdering him. Harry felt a chill.

"Does anyone have a phone?" He asked during dinner. Hermione said no and told him to try Hagrid.

"Hagrid is the same idiot that sent us into that deathtrap! No, screw this, i'm calling Orkin!"

Hermione was confused but tried again to persuade him not to make things worse.

"Go to Hagrid, he can help!"

Harry was unmoved and looked her dead in the eyes.

"What's next, consult The Carnivorous Muffin? Are you mad? Sending in clowns won't do anything but put them in hysterics and comedy CANNOT kill an Acromantula. No, i'm calling pest control. They can handle this."

Orkin was certainly Not prepared for this. Harry called them and reported a minor pest problem so they sent relatively few exterminators. Those same exterminators were wheeled back to the ambulance in various states of dismemberment, along with a note from Aragog

"Dear Exterminators

It has come to my attention that you seek to destroy us.

Bring it"

Signed Aragog

Next to the note was a dead bug. Orkin got the message. The US army arrived the next day.
