Am I the unique player that has this difficulty??

Hi to all. I've a simple question related to the balance of the game.. at the moment i need to upgrade power of my weapons (for killing ants or spiders) and tools. To do this, i need to craft an item that needs marble and quartzite. BUT: quartz and marble are INSIDE zones with ants or spiders (caves). So?? How it is supposed that I can do it?? Does it seem to be a nonsense, doesn't it?? Anyone else in my situation? Any suggestions? Thx very much for your help..
