What is the origin of the idiom "fall into a trap" and when to use it?

The idiom "fall into a trap" is derived from the concept of a physical trap used in hunting or capturing animals. These traps are designed to deceive or ensnare the prey, leading them into a situation from which they cannot easily escape. Over time, this concept of a physical trap was adapted into a metaphorical sense to describe situations where individuals are deceived, manipulated, or caught in a carefully laid plan or scheme. In other words, it is now used to describe someone who unwittingly becomes a victim of a deception, scheme, or situation that was set up to harm or disadvantage them.
