Bug Stomper

 is a challenge perk in Fallout: New Vegas. It is a Challenge Perk, thus is gained automatically after killing a certain number of 'insects'.

Despite being arachnids, not insects, Radscorpions count for this total.

''Pulling the legs off ants suits you well. You gain a damage bonus against insects.''

Effects
Bonus damage to mutated insects and arachnids (Radscorpions, Giant Ants, Radroaches, etc...). This perk stacks with other related perks such as Entomologist. Bug Stomper also allows you to literally stomp the corpses of bugs, causing them to explode as you walk over them. You gain experience for this.
