There are a few was to kill these pests you could use a pike or spear and aim for the small hitbox in the middle or if they swarm in a gauntlet use the flamethrower to easly kill them also they do 1hp damage each bite so make sure you have your blood packs or medical brew and stay safe
A noob's worst nightmare buzzing around,
Just be careful to have a tame to hear the sound,
Can kill it with a torch, if not
Also a hatchet, but some have not thought,
You can easily kill them with a sword or pic
Even though you can't tame this prick.
