How to unlock the Ant Farmer achievement in Earth Defense Force: Insect Armageddon - Definitive Guide
Clear out all the bad guys, and once you get the objective to blow open the wall to the tunnel, go ahead and do so.
Here's the important part!!!
The tunnel is filled with ants and ant hills. Simply do not blow up the ant hills and the ants will keep respawning. This is a great area because it's very close-quarter combat, and the ants die fairly easy with the right weapon.
My personal strategy was to place a turret about halfway down the tunnel, and then run back to the tunnel entrance and fire explosives.
Again, this method is also great to obtain armor upgrades... just be sure to finish the mission so that your points count! Each ant kill grants you 45 points on Inferno, and they die pretty quickly.
I use this method for spider kills-on remix (see guide by someone), I find going to far end of tunnel and out the other side just on the lip is best so you can see all 3 anthills.
Towards the end of the stage, you will reach a wide pit that has two busted silos inside it. When you first approach the pit there will be three ant hills. They spawn the upgraded ants w/ metal parts, so they take a bit more to kill than regular ants.
Ants are the first standard enemy you encounter. They are the easiest to kill and are always plentiful. Accumulate a total of 10,000 ant kills across all playthroughs and modes. You earn these kills in both the story mode and survival mode. One playthrough of story mode will net you approximately 1000 kills.
Grind spot:
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.
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.
If you don't get this while going for all the other Campaign/Survival achievements (highly unlikely), it can be worked on best during Chapter 1, Mission 4 after you blow a hole into the drainage ditch. There are three ant hills inside which will continually spawn ants until blown up. Use a turret and high tier assault rifle to rack up kills on Normal.
