[Lab] yellow jackets and electricity

Make sure your design allows for the dead to fall down and not clog the mesh. From my experience with bees, when something gets in close to their front door, they'll investigate immediately. From the traffic in the video, that might become an issue. Perhaps make it adjustable. In the beginning, you might sacrifice some kills for smooth operation. Later, you adjust for a more thorough deathrate.

    You don't need to detect them at all...

    Just use two parallel meshes at a distance of about 3/4 the length
    of a yellow jacket...

    With opposing charges on the meshes, the yellow jackets become the

      I've already got some parts on order (including a disposable
        camera to get a zapper out).

      I'm a little concerned about how I will detect when they are
        in contact with the mesh. Perhaps just a motion detector. 


            I just took some video of the little buggers: http://mambohead.com/2011/08/arduino-bug-zapper-yellow-jacket-removal/

              the ceiling? I guess I have to seal the hole after I get
              rid of them.

            An Arduino-powered stun gun is not something I would want to
            fall into the hands of a species as devious as the squirrels

            If it's not high powered enough, and you're not against
              using chemicals, I dealt with a nasty bee (my fiancee is
              allergic) problem in my backyard using Raid "One Shot"
              wasp killer.

                      Hi Richard, 

                          Thanks for the note.

                          I figured keeping a coil charged might be
                            expensive on the batteries. Seems the next
                            place to go is keeping a capacitor charged.
                            As I mentioned in the blog post, a
                            disposable camera may have enough hardware
                            to do this. May not be as high a voltage but
                            it might work. 

                          So it just comes down to triggering the
                            high voltage thing. 

                          I'm all ears on how to trigger it but I
                            figured I could just use an arduino because
                            the labor content may be lower. There might
                            be something that can save some pennies but
                            I think for the pain a community of yellow
                            jackets causes, it's okay if it uses an
                            arduino for a couple days.

                          Even if the Squirrels steal it.

                                I think the idea is to keep it charged
                                so that it does its work on

                                Does it really need an arduino, or just
                                a wired power supply and a way

                                of forcing all entering and exiting
                                wasps of touching the charged wires?

                                I've seen one of those at a friend's
                                cottage.  It is only $10, so it

                                might be worth just buying one to find
                                out how it works and adapt it for

                                automatic use with your wasp nest.  We
                                had one in the floor of our

                                balcony.  It was a nuisance...


                                You might want to adapt it with very
                                fine wires brushing around the hole

                                (but if the wire is too fine, it might
                                fuse instead of delivering the

                                intended shock to an insect...)
