Defin­ing some Terms: Here is an illus­tra­tion of the anato­my of a mouse trap, just so you know what the terms I use refer to.Removing and repositioning staple in mouse trap


The Sta­ple: The mouse­trap I bought had a small sta­ple which held the lever arm (the wire which is loose­ly attached at one end) from swing­ing around in the pack­age. If yours has this, use the pli­ers to pull the sta­ple out and then press it into the end of theUsing a stapler to insert a string guide wood mouse­trap base, just under the trig­ger which holds the cheese. Place it so the hole through the sta­ple is going up-and-down. If yours does­n’t come with this sta­ple, use a sta­pler or sta­ple gun to put a sta­ple in the same place. Make sure the sta­ple does­n’t go in all the way, but allow room for a string to run under it.


Cutting notches for the Mouse Trap Booby TrapNotch­es: Use the saw, if you have one, to make slots about 1/16″ to 1/8″ deep, on each edge of the stick at “Line C”. These notch­es are where one end of the boo­by trap string will be tied, keep­ing it from slid­ing along the stick. I just used a hack­saw blade. If you don’t have a saw or saw blade, you could use a knife to whit­tle small notch­es.


Clamping the mouse trap to the stick while glueingGlue: Glue the mouse­trap to the stick, with the “cheese trig­ger” end near “Line A” and the oppo­site end near “Line B”. Use the clothes­pins or small clamps, if you have them, to clamp the pieces until they dry. If you don’t have clamps, use some books to hold the pieces tight while dry­ing.

Tying the string to the cheese triggerAttach the string: A 3′ length of string should gen­er­al­ly be all that is need­ed, but keep in mind that it is easy to replace it with a longer one if you have an idea that requires it, or cut it short­er if help­ful. I pre­fer black uphol­stery thread. It is strong and the black col­or makes is hard­er to see. Sewing thread is as strong as is need­ed to set off the trap, and it is also hard­er to see than, say, kite string. Thread the string up through the sta­ple, feed it under the spring-loaded trap wire, then tie it to the “cheese trig­ger”. The mouse­trap I have has a plas­tic “cheese trig­ger” made to look like swiss cheese, so I tied the string to the hole clos­est to the end of the trig­ger. The pur­pose of the sta­ple is to con­vert a pull of the string from any direc­tion into a down­ward pull to set off the trap.

    It would be fun to see videos of peo­ple get­ting “caught” with one of these. Post them to YouTube, and share the address here.

    My broth­er used to nail me with these things all the time. We had a trap war for the bet­ter part of a year. I ought to build one just for old-timey sake!
