Life in the tropics comes with many bugs. After studying the eating habits of the local gecko population I came up with this idea for a natural order gecko powered bug "zapper".
Basically, geckos love window screens because their little claw toes can grip it very well. They hide in the shade of the
frame and dart out at any insect that is caught in the all powerful tracker beam, that being a light bulb. They are extremely efficient.
My idea is a wooden box frame with screens covering 5 sides, the bottoming being solid. In the center the box is an LED, preferably a color that attracts bugs and also solar powered and easily accessible.
Just beneath this would be some "gecko condos" where they could live and multiply. They seem to like little crevices, so maybe jut some slates. This could be hung or put on the end of a pole.
If you could get 6 or so geckos on the lantern it would be most ideal.
