Once set, Traps can be baited with Food items attractive to said animals. Baited or not, a Trap will trigger once a small mob moves close enough to it.

Traps are set by placing them on the ground and can be picked up again at any time. To bait a Trap once set, simply place a food item in it. Bait will be consumed upon a successful catch. Once a Trap has caught something, it will shake and rattle around with the animal inside.
Traps do not need bait in order to catch creatures; if a creature touches the Trap for any reason, it will fall and possibly catch it. This means if a Trap is placed directly on top of a Rabbit Hole, it will attempt to catch the Rabbit when it leaves home or comes back. However, sometimes a Rabbit will disappear into its hole before the Trap falls completely, leaving no loot.
When a Trap is picked up from the ground still set to catch an animal, no durability is lost, allowing it to be moved around freely. When a Trap is picked up after being triggered, it will lose durability. A Trap will lose durability whether or not it catches the animal that triggered it.
Frogs and Spiders die when the Traps that caught them are picked up, leaving their respective drops in the player's inventory. Rabbits and Beardlings are left alive.
Traps can also be used to mark notable areas on the map, as Trap icons appear wherever they are left.
A hostile creature can be lured into a Trap if it is chasing the player character; Spiders for example will always try to travel in a straight line and make no effort to avoid traps or other obstacles. Traps can be used in this way to form a barrier when destroying Spider Dens, or as a great method to farm Silk.
Traps are particularly useful during Winter, as they can be spread around a large area and placed atop Rabbit Holes for instant capture. In vanilla Don't Starve, Chests can be built nearby Rabbit Holes and filled with Rabbits to create a food stockpile.
In DLCs, the creatures caught under a trap will struggle for a few days before starving to death and dropping their loot on the ground. For example, a Rabbit will starve under a trap in two days, the same time it does in the inventory. If the loot (such as a Morsel) can spoil, it will do so as normal while on the ground. The loot will also be open for any creatures to eat or steal as their normal rules. After the creature has starved to death, the trap will remain in its sprung state.
In The Gorge event for Don't Starve Together, Traps function almost identically to the way they do in normal gameplay, other than the fact that they have no durability and can be used an infinite amount of times. They are used to catch Rabbits. Traps can be purchased from Billy for 4 Old Coins each.
- Creatures that cannot be caught in the Trap can still eat food used as a bait in the Trap. Traps with baits should be placed away from Pigs (omnivore) and Gobblers (herbivore) in order for them to be more effective.
- Birds will fly down to Traps baited with Seeds, but they will not be caught. Bird Trap can be used to catch Birds.
- Traps can be used to kill Spiders and Frogs without aggroing any others in close proximity. This can turn events such as Frog Rain into a way to easily obtain food without the risk of getting mobbed.
- Caught Rabbits or Crabbits can be left to starve to death, either in the trap or in the inventory. This gives the same items as murdering them but without raising the player's Naughtiness level.
- Traps found near Skeletons as part of Set Pieces have a random amount of durability. Sometimes, a Trap may be at 0%; they can be used to trap animals infinitely and will never break, presumably because their durability cannot go down.
- Schrödinger's Rabbit: while a Rabbit is in the middle of springing a Trap, it is possible to kill the Rabbit, receiving a Morsel and still obtaining a live Rabbit (although this is fairly hard to time correctly).
- When a Trap catches an animal and is picked up before it completely falls down, the prey will disappear and the Trap will lose durability as normal.
