For something thats works and is fun for the whole family 3 and up try
The Amazing Handheld Bug Zapper. Get one for everyone. Its fun to hear
bugs Pop and light up. It even takes down horse flys and bees. But they
are cheap and cheaply made and last about 6 months, so stock up now.
Keep one in every room.

No Zapper is quiet since extremely high voltage is arching through the
bug melting it.
