Ant's life studio Help please

Hello, I recently purchased the "ant's life studio" by bandai

https://www.japantrendshop.com/ants-life-studio-virtual-ant-farm-p-46.html

The seller told me that it is easy to understand, but I can;t read japanese and neither the seller.... <_<

I would like to know how do I ward the nasty predator bug.

what to do with the other bugs (spider and other ant)?

how do I unlock the items?

and how do I affect the nest shape?

I can answer a couple of your questions.

Tapping the screen can usually ward off predators. Some predators are not easily deterred and will make repeated returns in hopes of catching you off guard. (One of the predators even "plays dead" and won't leave without exhausting every attempt to catch an ant.) You can also use 'sugar cubes?" to keep your ants in/near their home until predators are clear. (I have NO IDEA how to prevent the earthworm.)

Unlocking, I believe, is done by just simply playing and the more time you "log", you unlock more items.

Nest shape? I'm unsure honestly...

tapping the screen? never tried that before. do i tap it continuously until the predator leaves or just few times?

and i also wonder if anyone knows what the items are for?

i think most of them are just foods, but are there any difference for each of them?
