This guide is quite simple. This guide will teach you how to master the Pest Control Fighting Style. The classes best for this Fighting Style are the Pyro, Demoman (Demoknight), and Sniper.

The Pest Control Fighting Style is taking out the "pests" that don't do much harm alone, but could be dangerous in groups i.e Scouts, Snipers, Spies, Demomen, Pyro, and Engineers.

The loadout for the Pyro can be anything.
The loadout for the Sniper can have any Primary weapon, a Razorback or Cozy Camper, and a Tribalman's Shiv
The loadout for the Demoman is a Demoknight loadout. Any boots, any shield, but I recommend the Persian Persuader for the melee weapon because of its faster charge rate.
