  I live in an area that has lots of small rodents that love a tasty cricket. Also, with rodents come snakes who like to snack on their mamalian buddies and find ways to cozy up inside your house. So, basically, my question is: does the electric cricket attract pesky critters who like to eat real crickets?

  I tried putting this together but am confused. The schematic doesn't show a polarity for the capacitors - but the picture looks like there are electrolytic capacitors. Should they be elctrolytic? If so, what is the polarity?
  
  Also, is there another type of cheaply-made oscillator that would work? Anybody have a schematic or a link to other types of sounds that could be generated with such low power and low cost?

  The 100uF and the 6.8uF are electrolytic, with polarity.
  
  The straight side of the capacitor symbol is +. For both the 100uF and the 6.8uF caps in thie circuit diagram, that would be up.
  
  The others (10n, 22n) are ceramic, without polarity.
