Easy DIY Survival Traps From A Bottle How to Make A Fish Trap From Trash

These simple survival traps utilize commonly found trash that washes up on all creeks, rivers, oceans, and any other water soure. These survival traps and fish traps are fantastic because they not only can work to collect small insects, or fish, but they can be made from almost any plastic bottle, in any size and take just a few minutes to make, and you need just three basic things to make them! 

How do Fish Traps Work

Bottle fish traps are ingenious tools designed to capture fish in a simple yet effective manner. Typically crafted from plastic bottles, these traps take advantage of the fish's natural instincts. A funnel-shaped entrance leads the fish into the bottle, where the narrower neck prevents them from easily swimming back out. Once inside, the fish are less likely to find their way out, creating a secure and humane trap. This method relies on the fish being lured into the trap either by bait or their own curiosity, making it an efficient and eco-friendly way to catch fish without the need for constant monitoring. Bottle fish traps are a testament to the resourcefulness of utilizing everyday items for survival and subsistence needs.

How to Make a DIY Fish Trap

Materials List:

  • Plastic Bottle: These small DIY fish trap work with a single bottle, but it works better with two (much easier to empty) they don't need to be a specific size, but the larger the bottle opening the larger the animals can fit into it.
  • Cordage: This will be used to tie the cut bottle tops to the body of the bottle, and if your making this a fishing trap, to tie to your bottle from the bank. HERE is a link to an awesome tool that can make cordage from the wasted portions of your two liter bottle to reduce waste. 
  • Cutting Tool : To make these small survival traps you'll have to cut a plastic bottle, and pierce it with several small holes.

You can use a small blade, but something round works best to pierce holes along the outside (for air for insects, or for water to flood in or out for fish) you can also do this by heating a round metal object to pierce the bottle along the lines shown above. Tie the two portions together with cordage wire, or zip ties works best but anything will do for a short time.

For collecting insects you'll want to bait your bottle with something to draw them. You can catch any manner of land based insects, reptiles, or small animals in this trap so beware of poisonous reptiles, and insects. Be sure to make either a ramp, or bury the bottle so that your target prey can easily get inside. To empty the bottle simply remove the cap.
