I enjoy learning about traps because of my philosophy: in the advent of an emergency big game will be hunting clean in any populated area within a matter of weeks; however, small critters will always be around to trap and eat if you have the skills and tools. One of the most common edible critters that you will find lurking in your neighborhood are probably rabbits, be they jack, cotton tail, or peter. I swear I’ve seen jack rabbits in Montana as large as small deer, but that’s for another day.
Simply described, a snare is an anchored noose set to catch animals such as squirrels and rabbits. In the US they are used both for catching food and eliminating unwanted garden critters. Snares are one of the simplest traps and can be very effective. if it is not an emergency then do a little research and find out what regulatory laws are in place for snares; this is chiefly to avoid animal cruelty and avoid undesired critters being caught. As with much of trapping; some states require tags and a license.
There is no standard for snare building; and the examples I’ve shared pictures of are the simplest type and all it takes is a bit of string or wire and the ability to identify likely animal trails in the bushes. If you’ve never done this, try taking a walk in the park and paying attention to the bushes; you will likely pick up on where the small animal traffic is and start noticing the little tunnels through the foliage. As a quick note, when you do set one do not rely on a single string; its only string so don’t skimp; if you can throw a dozen snares out and broaden your likelihood of catching dinner. Also, keep the knot on the noose loose so the action can slide freely.
