A Bug-Type Bounty in Pokémon GO
The Pokémon GO Bug Out event crawls into your area starting April 2.
March 28, 2019
Starting in early April, Pokémon GO is bugging out! From April 2 at 20:00 UTC until April 9 at 20:00 UTC, swarm into your neighborhood and look for Bug-type Pokémon in the Bug Out event. Bug-type Pokémon will appear more frequently in the wild, and Incense will last twice as long. Incense will also be more effective in drawing out Pokémon for you to catch! There will also be Bug-type Pokémon Field Research available during this event for you to complete for a limited time.
Explore the outdoors to see what Bug-type Pokémon you can find in the Pokémon GO Bug Out event!
