Spider Catcher

About: Dad, Maker, biker, trekker, I like sciences, technology, martial art and wild.

Hi everybody, on this instructable, I will build a spider catcher. Why? Because my wife is scared by spiders, and I don't like black traces on walls... and they will be happyest outdoor.

Are you effraid by spiders ? yes ? Hack your life !

Step 1: Components and Tools Needed

Tools :

- cutter

- manual drill (optional)

- glue (glue gun is welcome)

- tape

- pen


- 2 plastics bottles

- a stem (wooden skewer, metal ...)

Step 2: Pierce the Stopper

To begin, pierce the stopper in his center with the manuel drill (or with a cutter but caution !).

The hole should allow the turning stem, no more.

Step 3: The Chamber

To make the chamber (which will be the cage), cut the bottle:

The height of the bottle should be less than the length of the stem, of a way that it exceeds a few centimeters through the cap.

Now cut the bottom of the bottle, leaving about 3 cm high.

Then, cut a little less than half of the bottom (the red area in the picture).

Step 4: The Mechanism

Now cut the bottom of the 2nd bottle, leaving about 2cm in height.

Cut the bottom obtained in 2.

Pierce the center of this background and that of the chamber.

Made pass the stem in this bottom, and paste, leaving about 0.5cm exeed.

Step 5: Assembly

Finally, put the mechanism in the first background, close with the first part, close the stopper.

Tape the 2 parts of the bottle (it would be a pity that it opens with a spider inside :D)

Step 6: Catch a Spider !

Note: dosen't work with Spider-man.

    supposedly if you want to keep yr house spider free you need a soundwave of 30-55kHz. Was hoping to find an instructable on that. That is how I came here :-)
    Guess i have to design one myself :-)

    Interesting idea. Not sure I would go to all this trouble, but still a pretty cool design...

    I usually just use a handy container (usually a plastic cup or container, but anything close at hand and big enough to hold the spider will work...). Set the container down over the spider, then slip a piece of stiff card stock (tablet backing, an old greeting card, even a piece of copier paper folded over a couple of times to give it some stiffness will usually do in a pinch) under it to trap the spider. Obviously, whatever you use has to be big enough to cover the opening of your container. Most times the spider crawls up into the cup, but even if it doesn't, it will usually move as I slide the card stock under, so the legs don't get caught between the card and the edge of the cup. (If I wanted to hurt the spider, I probably would have just stomped on it.)

    Once you have it trapped, turn the cup over while holding the card stock in place and take it to a good catch and release point (i.e. outside the house, preferably far enough away so it is unlikely to find its way back in...)

    It sounds more complicated than it is...

    Hi, thanks for your feedback! I use the same method that you, but for my wife, the engagement range is too short ... And even with my system , she finds it too short. I will enlarge the handle, and enlarge the chamber. For me, no change :D

    awesome! I TOTALLY need this! I hate spiders and their guts (when smashed) and they are usually closer to the ceiling. probably will work for ladybugs, too? i have about 11-12 pet ladybugs at home, lol

    You can catch everything that is smaller than the opening. Including ladybugs... Post a photo if You build it!

    As home made spider catchers go, this is pretty good!
