Atomicrops

This achievement is fairly simple and can be completed in a standard run.

Beeson are flying Bee/Bison enemies and can be found in all areas and all tiers. Beeson are non hostile, they travel in herds but can damage the player on contact. The perk Beeson Whisperer means they can't even damage you, making this challenge even easier.

The Biodegrader or the Sriracha Soaker are ideal weapons because of their splash damage. I'd heavily suggest using the second character (Rye) because he has the best base odds to keep his weapon after each round. Increasing your fighting stats when possible and upgrading your weapon is advised too.

Instead of actively searching for them I've found success just clearing them as they appeared as I clear camps in the wild zones and you should get this achievement in the Autumn/Winter section.
