How to unlock the War Against Soaring Pests Award achievement in Earth Defense Force: Insect Armageddon - Definitive Guide
A)Ants
or
B)Spiders and wasps
If the ants spawn, just restart level until you get wasps and spiders (you have about a 50% chance on each). There are eight wasps in this area. Playing without bots, you are guaranteed eight wasp kills. Just kill everything in the area until you are ordered to plant the charge then restart the area. It records any kills you get without completing the stage, but you won't get xp. Playing with bots, I was able to average about 6 kills each run, but it went a little faster with the bots.
Wasps are typically deployed in conjunction with gunships. They are a bit difficult to kill due to the fact that they move constantly. Equip a missile launcher that has an autolock ability to make these kills easier. Accumulate a total of 100 wasp kills across your playthroughs and modes. You earn these kills in both the story mode and survival mode.
Grind spots:
Go to Mission 4 in Chapter 3. You'll want to play offline by yourself to maximize the amount of kills you receive. There are two major fights in this mission. The first fight pits you against ants, spiders and 3 small hectors. Defeat them and progress. When you get to the boss battle don't kill her. An infinite amount of ants, spiders and wasps will spawn. Kill as many as you want before finally finishing off the boss. When playing solo with the two AI partners be aware that they will eventually kill the boss on their own ending your kill grind.
Chapter 3 Mission 1 has another excellent spot to grind these kills if need be. You'll come to a fight where turrets are provided and two carriers arrive. The carriers will deploy gunships and along with the gunships, wasps arrive. Approximately 10 show up during this battle.
Additionally any of the maps in survival mode offer a great way to rack up kills. See Good Start for details on where certain enemies are located and in what map/wave.
The best spot I've found to farm wasp kills is described in the "Scavenger" achievement description. There are dozens of them on Map 2 (Shallow Grave) of Survival as well.
