Those laser diodes aren&#39;t too expensive. <div><br></div><div>But I guess I need current drivers for 30.00 (that&#39;s 2 drivers).</div><div><br></div><div>I think I need a heat sink (45.00?) and perhaps a lens (5.00).</div>

<div><br></div><div><div>I think if it could work it could make for a pretty effective way of stopping the yellow jackets. It would just be a matter of putting this device near where they enter their nest and it would (in theory get rid of the community).</div>

<div><br></div><div>These pests are an ongoing problem so I am prepared to come up with a device even it if take some time and I have to learn a few things. As it stands every time I have to deal with the little buggers it takes plenty of time to assess, take precautions and use various means to combat them and follow up.</div>

<div><br></div><div>The only concern I have for the laser is it&#39;s dangerous for humans. I suppose if the lens were dropped then it would only do damage at close range. Perhaps there could be a tube they have to get through and the laser is in there and the beam can&#39;t get out. </div>

<div><br></div><div>This laser thing is worth looking into since it could have other applications...</div><div><br></div><div>I ordered a disposable camera for about 12 bucks with shipping. That might work too. </div><div>

<br></div><div>Either way I think I need a trigger to only deliver the punch when the animal is in the right area. (So the thing can run for a while on batteries). Like Michael says, if there is continuous charge on the grid (in the high voltage case), it will discharge on contact. Hmmm, that&#39;s sounding better all the time, all I have to do is keep the capacitor charged.</div>

<div><br></div><div>I suppose I might not get lucky and reuse this thing since they may not have an exclusive access point. It&#39;s just that this time they&#39;re in the roof and I can&#39;t use my usual means.</div><div>

    You don&#39;t need to detect them at all...<br>
    Just use two parallel meshes at a distance of about 3/4 the length
    of a yellow jacket...<br>
    With opposing charges on the meshes, the yellow jackets become the

                                might be worth just buying one to find
                                out how it works and adapt it for<br>
                                automatic use with your wasp nest.  We
                                had one in the floor of our<br>
                                balcony.  It was a nuisance...<br>
                                <br>
                                You might want to adapt it with very
                                fine wires brushing around the hole<br>
                                (but if the wire is too fine, it might
                                fuse instead of delivering the<br>
                                intended shock to an insect...)<br>

                                  &gt; &gt;&gt; Let&#39;s say I have a nasty
                                  yellow jacket nest that&#39;s starting to
                                  cause<br>
                                  &gt; &gt;&gt; problems.<br>
                                  &gt; &gt;&gt;<br>
                                  &gt; &gt;&gt; I&#39;ve dealt with these in
                                  the past when the next is very exposed
                                  but this<br>
                                  &gt; &gt;&gt; time I only have access
                                  to an opening about an inch where they
                                  are coming<br>
                                  &gt; &gt;&gt; and going.<br>
                                  &gt; &gt;&gt;<br>
                                  &gt; &gt;&gt; Has anybody ever tried
                                  to put some sort of zapper near an
                                  entrance? Seems<br>
                                  &gt; &gt;&gt; that should be an easy
                                  way to get them.<br>
                                  &gt; &gt;&gt;<br>
                                  &gt; &gt;&gt; A trap seems to take
                                  long because they only go into it once
                                  in a while so<br>
                                  &gt; &gt;&gt; it takes a long while.<br>
                                  &gt; &gt;&gt;<br>
                                  &gt; &gt;&gt; I figure if I put a
                                  couple of electrodes near the hole,
                                  they could<br>
                                  &gt; &gt;&gt; complete the gap.<br>
                                  &gt; &gt;&gt;<br>
                                  &gt; &gt;&gt; If this would work, I
                                  wonder how many bugs a couple of
                                  D-cells could zap?<br>
