(please excuse grammatical mistakes or spelling mistakes, English is not my native language)

Chapter One: Hunter Attack - Antlion Battle

Chapter One begins after Alyx got attacked by the hunter. You will enter the mine until you find a pit stuffed with carts. On the last level, with the poison headcrab, you enter an illuminated hole where you’ll find the first 5 grubs [#1-5].

You enter a new part of the mine. In the first room are 3 grubs, located on the ground. [#143-145]

In the middle you will find a wooden cover with grenades and supply crates on top. Remove them before you step on the cover, because it will collapse and you along with the supplies will fall down into a dark abyss.

Chapter Three: Elevator Fight - Leaving the Mine

Chapter Three: Elevator Fight – Leaving the Mine
After you fought off the antlions and zombies you’ll come to a gate. The vortigaunt arrives soon after you and activates the generator. From now on the search for grubs continues.
Soon after you crossed the room with the corpse you will meet the antlion guardian. It’s impossible to kill him with your weapons, so don’t even try.

When you turn left you’ll find 6 grubs and a supply crate at the end of the passage. [#227-232]

When you turn right you’ll find 4 grubs in front of the carts. [#233-236]

Run to the yellow entrance to your right, covered by 3 grubs. Until the exit are 6 more to find.
[#287-295]

Try to run past the antlion guardian to the first yellow entrance you see, covered by 2 grubs.
The inside contains 3 more. [#296-300]

Wait until your energy has restored and then run until you see another yellow entrance, covered with 3 grubs. The inside contains 3 more. [#301-306]

Get to the exit, where you find 5 grubs, and run to your left. [#307-311]

Get the gear and put it into the elevator. The vortigaunt comes down and opens the gate. Next to the generator is a grub. [#329]

Just after you passed the gate are 3 grubs on your right. [#330-332]

The vortigaunt gets the vital extract and brings it to Alyx. After the G-Man sequence you leave the area and take the elevator to an upper level.
The last grub is located behind some wooden planks you will come across right after you left the elevator [#333]

At this point you should get the achievement. Congratulations!

Tips and Hints

Using the Guide & Keeping the Overview:
Be sure to have this guide by your side when you play, on your phone or second monitor, to always have an eye on it.
Some grubs are hidden and you will miss them easily, so make sure to move slowly and attentively.
To control the total number of grubs you have killed it’s necessary to open up the ACHIEVEMENTS section in the main menu. Just hit ESC when you’re in game to check quickly.

Killing the Grubs:
Grubs on the ground and at the bottom of the walls are easy to kill just by walking over or towards them. If they are located nearby but are not accessible you can easily kill them with the Gravity Gun. In case they are located further away use the 9mm Pistol because you can aim a lot more precisely and you will find various ammunition around.

Avoid killing the grubs with grenades, the SMG or the shotgun. You will lose overview over the number of grubs you have killed, which will aggravate to control if you spared one by accident or not. Furthermore, you need those weapons to kill enemies you will come across like antlions, zombies or barnacles.

Cheating:
It's useless to get to the grubs by using “noclip” or other cheats. The game won’t count any achievements as long as you have cheats activated, so you have to start from the beginning of the game and get them in the traditional way.

Special thanks to my friends rektangle for testing and proofreading this guide!

[ojmygl]

thank you so much!

[Kadae]

There is easer way. Console.

bind mwheelup "give npc_antlion_grub"

No cheats.

[reagold]

What a great guide! Thank you! I used the guide + the achievements tab inside the game to keep the count right, and even then was hard!

[iSoul95]

sensational guide, brilliant- thank you

[One Cut]

I tried this achievement without a guide and got 332/333 myself... Turns out I missed the one inside the locker (#27) and have to start ALL over... sigh... Thanks for the guide though! It helped me figure out which one I missed.

Thank you gamer friend!!!!

[The Bread Man]

Thank you so much for this guide. Not having pictures for some of the locations made it a bit hard at times, but quicksaving helped me whenever I realized I must've missed some. The parts where you say the "You can't go back there once you enter this area" type-of-thing helps a ton because it helps narrow down where you missed grubs. That being said this achievement still took a while for me to get even with the guide but I highly doubt I could've found them on my own. I'm trying to 100% more games on Steam as I only have 2 (as of writing) and for some of the harder achievements, I've been relying on guides like these (example: I completed all the HL2 achievements recently and needed a guide for Lambda Locator. This guide here is basically the HL2 ep2 equivalent to that).

TL;DR: Thank you for making this; super helpful if you're achievement-hunting. To everyone here, read the guide carefully and don't be afraid to make frequent saves just in case.

for 227-236, you should say that the grubs are found shortly after the supply crate, as i saw none looking around there and when i turned left from there and over the ramp, then i saw the 6 grubs and the other grubs mentioned to the right.
