These supplies should include heavy wires and cords in your bug-out bag. Below are the things you will need and steps to make a snare trap with dental floss.

Materials you need:

  • Sticks
  • 2-3 packs of dental floss


  • Look for two medium-sized sticks and hammer them deep into the ground. They should be in at an angle where the other end of the sticks will cross each other.
  • Tie the ends of the sticks together so they will cross completely. It should make an “X” shape.
  • Put your hand in between them and try pulling them up to check if they are sturdy enough. The sticks shouldn't be popping out of the ground.
  • Look for a fairly thin stick and hit it into the ground directly in line with the other sticks.
  • Look for another stick that will serve as your bait stick and put it in between the crossed sticks. Keep inserting the stick forward until it meets the other stick that will hold it.
  • Carve a notch wherever the two sticks meet. It will hold the bait stick until the prey pushes it down on it causing it to get out of the notch. This will make the snare go and eventually trap the prey.
  • Look for a sapling or a tree with a thin trunk. It needs to be alive and fairly small.
  • Choose the correct height depending on what prey or animal you want to catch. Make sure you strip it down until there are no more leaves or branches because this will affect how fast it will snap back.
  • Cut a ring that will go all the way around the tree or sapling, then put your dental floss inside of it. You need to be sure the dental floss has the same length of the tree before you tie them up.
  • About 6 inches down, tie your bait stick.
  • At bottom, tie a snare depending on how big the prey you want to catch.
  • Bend your sapling down and put the snare in front of the angled sticks.
  • Put you bait stick in between the angled sticks. Make sure the side of the bait stick that you tie your floss to is facing the sapling.
  • Barely hook it to the notch.
  • Put the bait on the other end of the bait stick.
  • Wait for the prey to eat your bait, and it will eventually be trapped in the snare.

Below are the simple instructions to make a rope which is also a good dental floss strength test:


  • Cut several pieces of floss to the desired length. Make sure it is long enough because it will get shorter as you twist the floss.
  • Lay the threads together until they are all lined up and tie a knot on one end to keep them secured together.
  • Divide the bunch into two even sections.
  • Hold the two sections, one in each hand, and twist them in the same direction. It can be clockwise or counterclockwise as long as it is in the same direction. This motion will cause the two strands to wrap one another.
  • If you still want to make the rope longer, splice an additional bunch of threads into the tail end before it runs out.
  • Simply twist the new bunch right alongside the old bunch. You now have longer tails where you can continue spinning your rope.
  • Once you have reached the desired length, tie a knot at the end of the rope to keep it from unraveling.
