Exterminator - Vol. 5 Ch. 22

[MangaDex]

A much better plant has been found, but only Naoki and Ayl can use it to exterminate? Gonna need actual tactics for that instead of brute forcing everything...

I feel like I've been seeing visuals of falling rain and/or flash floods in the previous 2-3 chapters. Only now is this actually starting? I thought the swarms already started and were just taking some time to reach town.
