Built from nothing but scrap plywood and spare or recycled hardware for completely free, or you could build it for really cheap if you had to buy anything

With an "industrious" back yard and a large vacant field behind the neighbors across the street we occasionally find an opossum nesting somewhere we can usually catch with a gloved hand. Yesterday I spotted a juvenile running across the street, I gave chase but it hid in the neighbors garage and I lost track of it after a few minutes.

Figured it mustn't be difficult or complicated and came up with this after having seen a couple of other traps before.

Step 1: Tools and Supplies

You will need the following supplies:
1/2" plywood
1/2" x 1/2" strip
4 hinges
2 small washers
Bailing wire / metal hanger
Twine / String

You will need the following tools:
Drill / Driver
Tape Measure
Side Cutters
Razor Blade
Drill bit
*optional* A radio to jam out to
What kind of bait do you use?
I just used some dry cat food. If you use some Trix cereal you'ld have better luck catching the Trix rabbit, silly rabbit....
i use peanut butter. its cheap and it works great
<p>Hmm, I was gonna say cut smallish/mediumish holes in each surface, staple cage wire over 'em --- but looks like you already suggested that.</p>
<p>Very awesome indeed, I see you have mastered this art of an outdoorsman!</p>
<p>We have been trying to catch this dog for over 3 weeks. She is in survival mode and very hard to catch. How big would we have to make this trap for her?</p>
<p>For a dog the size of one in the picture you would simply need to scale all sizes necessary up. Quick suggestions as guessed from the picture; Cut the floor 30&quot;W x 72&quot;L, and the walls would probably need to be about 30&quot; or maybe even 36&quot; tall. The key factor is that you need a box big enough for the dog to be able to walk into and not feel like something fishy is going on. The mechanics of the trigger and door locks will work for any size box, you just need to super-size. Do it right you could make one big enough to trap an elephant, or small enough to catch just a field mouse.</p>
<p>How large of an animal can this be used for at this size?</p>
<p>When finished you have a roughly 11.5&quot;x11.5&quot; tunnel that is about 36&quot; long for the sizes given in Step 2.</p>
i made something similar out of cardboard , it was kind of a one time use trap and it works fine used rubber bands and made a pressure plate from the cardboard , this is a lot more reliable though
Cardboard huh, that's pretty cool. I could definitely see using the double thick/double corrugated industrial stuff but given enough time your prey would probably be able to chew his way out, though not impossible with the plywood, way to be creative.
just what I was looking for
Glad to help.

What's a sear???? Also curious why you posted in RED letters that can't be read? What's the matter with white letters???
the word &quot;sear&quot; is from the firearms dictionary. it refers to the part that actually holds back and has the specially ground ledge to release the firing pin, in most modern firearms the trigger is connected to the sear by a bar or linkage. As for the red letters it looked more standout on my laptop screen when I was editing the pics, sorry about that.
Next you might even add screened in air holes.
I built a trap similar to this to catch some raccoons that were coming in the house through the cat door to eat the cat's food. But we caught two neighbor cats and a possum before we ever got a raccoon. And the raccoon we caught was a juvenile. So there's a sizing issue. I know this sounds obvious, but before you set out to trap something, figure out what size your prey is and make the trap big enough or conversely, small enough so you don't catch something you don't want to. Not that it matters that much with a live trap. But even a live trap can kill if you don't check it frequently because the animal can overheat or get dehydrated if the trap is out in the sun. Also, if you want to be a law abiding citizen, you might want to check state laws on trapping. In CA you don't need a license to trap an animal that is damaging your property. Loosely interpreted, this means you can trap an animal without permission if it's not for the purpose of eating it or killing it for its fur. There is also the business of what to do with the animal you trapped. Again, there is opportunity here for breaking some laws. Not that you're likely to get caught, but it's good to know what the law is.
A good point about checking your state's game laws. Many states allow you to use (i.e. eat, skin, etc) animals trapped as &quot;Nuisances&quot; on your own property, but not all. Some places a trapping license (allowing you to trap on a neighbor's land, for example) is inexpensive, others it is burdensome. Most Wal-Mart stores and most sporting goods or hunting supply stores have free booklets of state game laws, and of course, they are pretty easy to find and download online.
Ewwww, wal-mart, nasty.
I built the trap of general size so that it could be used again for other critters we might encounter. Since opossum are nocturnal I checked my trap every morning, what's the point of a humane trap if you kill em slowly. Everybody, PLEASE, ethics are important in this. I hunt, probably could have shot the little guy with a pellet rifle and it would have killed it faster then 3 days in a box. Didn't see much point in killing it as I don't make opossum a food stock. As for this hell hole of CA we live in; opossum, skunk, raccoon, and ground squirrel are considered varmint. You need a hunting license (so the state feels better that you know some basic safety in the field) to shoot but you can shoot them without limit, tags, or reporting. And yes, as long as they're being trapped for nuisance and not for food/fur then there is no problems.
Good job!!! <br> <br>I would also advise a &quot;window&quot; to see what you have inside, though I recommend a piece of plexiglass (with a 'shutter'), rather than mesh! My father built a &quot;live trap&quot; for nuisance skunks....they could be transported to a NON-residential area &amp; released. (Also, skunks will not spray while in an enclosed space...they don't like the smell anymore than you do!!!!) A good 'bait' that is less apt to catch cats is peanut butter.....skunks &amp; raccoons love it, cats...not so much. <br> <br>Dad's first &quot;pesky skunk-traps&quot; were made of plywood. But he later made some out of sheet-metal for a Fish &amp; Game officer in eastern Oregon, while he was there visiting. <br> <br>His mechanism for closing the door was quite different, but I'm sure yours is very effective!
The nice thing about the trigger/sear set up is that if the sear pin is left perfectly straight the weight of the trigger boards will pull the pin with no problem, you have to bend the pin to keep the trap set. If you can bend the pin just barely enough the triggers could be as sensitive as 1/4 pound, maybe even 2 ounces.
I have built live traps in my younger years similar but with a Guillotine door to close behind them. I also use chicken wire to make a window to see what I had in my trap. Skunks don't like it when you open the door and out it comes lol. I would add a window if I was you no surprises when the door opens.
Theoretically your just opening the door enough to see what you caught then closing it again, unless your letting out the neighbors cat. The only time I would want to fully open the door on something caught for disposal would be when I get to my release area, a nice little year round creek about 30 minutes out into the country.
hi thanks for this nice job / it is a box trap made these when i was a boy years ago<br> good job nice photos showing the build
Thanks, not bad for my first time.
A little over complicated, but a nice job on the ible. Like the other poster wrote a guillotine door is much simpler and the screen on the other end is a must. I don't like surprises.
A screen window was something I mentioned in the last step of the instructable, both for viewing what's inside and for air flow. As for guillotine doors, you are counting on the weight of the door to be the lock keeping the door closed, these doors will hold my fist punching the door (did it as a demonstration for the neighbor).
