There was this base in my clan war that had 6 cc loons and I had the idea of doing a pentalaloon as long as I could get rid of the AQ. I wondered how many poisons i needed to take out the AQ, and the calculation said 3 (450 dmg for lvl 3 poison and enemy AQ had 1000hp), but when I asked my clanmate he said that it would not work and requires about 12 poison spells. He did not know why though... so I have come to the forums to ask if anyone knew the reason poison spells don't work effectively on the AQ and for some video showing it as I could not find any. I did not end up trying it myself since it was for a clan war attack and I did not want to risk a fail.
I thought one of the reasons you need more poisons might be that the AQ moves around her alter, but her movement radius is less than the poison radius and each of her movements is predictable if you watch her for 20 seconds while scouting the base.
