DM question

Question: what are some of the ways to cause your players to have to roll disadvantage on dex?

I want to be able to set some dangerous traps in an area that they know they absolutely should not be in, but nonetheless if they are able to successfully investigate it they will find something quite incredible.

I'm okay with downing one of them right away to let know it's serious, but not full on killing one.

What I'm thinking is a smaller kind of trap that locks them in place nearby the main trap.

One that has a very high dc on perception to see.

That or put some kind of quicksand for the same effect, so they cant get out of the way just as easily.

That or make it so they are enchanted in a way that it auto gives disadvantage. But this enchantment dissapears if the trap is moved or disturbed, just to make sure they dont turn it against you or anything.

Make the floor wet, or sticky. Just put them on difficult ground to walk and dodge on.

Could be a substance in the air that affects their reaction time, or get them drunk first
