First of all, they stopped appearing even if I hide my presence, and they no longer foolishly walk across the middle of the room. Instead, they seem to opt for crawling underneath furniture timidly to move around.
From that, Remilia has little means to reach them, and even using brute-force with its wings to scoop house yukkuri out turned out ineffective.
While it is still useful catching few house koyukkuri who had let their guard down, it is ultimately not enough to fill Remilia's belly.It has been a week since I got a Remilia for getting rid of house yukkuri.
Since it was originally wild yukkuri, while it was stupid, Remilia did its role of hunting well. It was able to kill in one strike, massacring house yukkuri one by one.
While initially, I was comforted by the assumption that all house yukkuri will be eliminated soon, even the paste-for-brain house yukkuri started taking countermeasures, and the number of yukkuri hunt by Remilia has started to decline recently.
