They are good at and like hidding some things of mine. In addition, I can't notice they are moving to their targets and bring around with them. On the top of that, they also have the skill to cut out of my memory where I put them.
I have some items to insects, so I can call them to get out of my house. But I don't have any cards to them. I have visited some libraries in order to find out a way to slay them at some times. Although I have found out the way, It always slip from my mind by them.
What should I do?
