Build a Homemade Mousetrap

Build a homemade mousetrap to safely nab a mouse, as our two simple (and humane) traps prove, including the wooden cell mousetrap and can mousetrap, and mousetrap diagrams and construction directions.

| November/December 1982

Use these instructions to build two different homemade mousetraps. One design resembles a wooden cell and the other uses a recycled soup-can. A diagram for the soup-can mousetrap can be found in the image gallery (above).

Wooden Cell Mousetrap

This "Old World" model is based on a Danish design and — although it fairly screams "Rube Goldberg" — it's functional (and even sort of fascinating).

To make it, you'll need an all-wire coat hanger, a strip of pine measuring 1/4 inches by 2-1/2 inches by 54 inches, another scrap of softwood with 3/4 inch by 1-1/4 inch by 4 inch dimensions, about two dozen 16-gauge, 5/8 inch wire brads and a 3-penny finishing nail. The only tools required are a coping saw, a ruler, a hammer, a nail set, a pair of wire cutters, and a drill with an assortment of bits.

Begin by cutting up your 1/4 inch plank to produce the pieces called for in the illustration. Once you've done so, use a No. 48 bit to drill lines of holes — keeping the individual bores about 5/16 inches apart—with each series parallel to and 1/4 inch from one of the short ends of the 1/4 inch by 2-1/2 inch by 9-1/4 inch and the 1/4 inch by 1-1/2 inch by 2-1/8 inch by 5 inch panels — and drill yet another hole through each of the latter parts, at a point 1 inch from the straight edge and 3-1/4 inches from the wide end. (To keep the openings lined up, it's best to clamp the matching pairs of pieces together, then bore the necessary holes. Note, also, that the lines of openings in the ends of the two wedge-shaped panels don't extend all the way across the pieces, but terminate 1-1/4 inches down from the peaked corners.)



Next, clip apart your coat hanger to form bars of two different lengths. (You'll need six that are 1-7/8 inches long and seven that are 2-3/4 inches long.) With this done, tack the box together using some wire brads (make sure its walls are positioned between the top and bottom boards, and that the bar holes in the upper and lower panels are at the same end of the box), then tap the seven hanger rods into place. Complete the cage by drilling a 1/8 inch hole through the bottom board, being certain it's centered and 3/4 inches from the end opposite the bars.

To assemble the ramp mechanism, first tack the narrow ends of the wedge-shaped pieces to the sides of the softwood block (the lower edges of the 1/4 inch walls should be flush with the bottom of the 3/4 inch by 1-1/4  inch by 4 inch plug, and the joint should be 1-3/4 inches long), then tap five more bars into the aligned openings. Also, make a security pin by cutting a 3/4 inch piece from the finishing nail and driving it into the bottom of the softwood block at a point 1 inch from its inside edge.

I used the plans at WWW.EASYWOODWORK.ORG to build my own mouse trap – I highly recommend you visit that website and check their plans out too. They are detailed and super easy to read and understand unlike several others I found online. The amount of plans there is mind-boggling… there’s like 16,000 plans or something like that for tons of different projects. Definitely enough to keep me busy with projects for many more years to come haha Go to WWW.EASYWOODWORK.ORG if you want some additional plans :)

Don't waste your time on the soupcan trap. It *doesn't* work. No doubt, it can, probably, catch some tiny percentage of mice. But, over all, it doesn't work because it's a design error. I could see from the beginning that it seemed flawed, but, I built it anyway because I'm waiting for some snap traps. All I've been doing is giving the little vermin free meals. As someone who has caught many rodents in snap traps (both, mice and rats), and have seen how frequently they make off with the bait a lot of the time, I can see what the problem, here, is. But, because whoever contributed this "gizmo" is probably picking people's brains in order to get us to tell *him* how to make it work, I refuse to state what it is. Even the picture, accompanying the skimpy instructions, looks like it was filched from somewhere. I doubt that the person actually tried it. I do like the way that it closes, and would like to see how well it would hold a trapped mouse. The problem is that part of the design needs to be improved. There is a reason as to why snap traps have stood the test of time. Snap traps are, probably, the best simple-machine blend of form and function for catching these destructive little thieves. And, they are reusable, too. Useless ideas, like this one, belong in a Tom and Jerry cartoon.

DO NOT release living mice and rats back into the world. They are vermin, carry disease, eat tons of valuable food each year and reproduce like crazy.
