I was playing grounded 2 and I got to this quest, I went to the marker and there were no bugs there just candy.

Same here. No bugs spawned 

Me to theres no bugs

 

none at the stone stash either 

 

i found out the bugs got stuck in the pipe i just had to wait for them to jump through it

 

Many people are having issues with this type of missions, the bugs are there but stuck somewhere you can try to hit them even if they are inside the walls and floors.

I still have problkem with this Objective, there are no Gurasds to kill, I reported it 3 days ago by mail and on steam discussion under technical but still nothing, I cant comtinue progress inggame if I cant do this objective plz fix it Regards Facemanwario

Same here...
