Can Bug Zappers Handle Large Beetles in a Greenhouse?

Insects & Creepy-Crawlies

Hey everyone,
I run a small organic greenhouse, and giant June beetles are devouring my tomato plants. Desperate to avoid pesticides, I installed ​​UV bug zappers​ last month. Here’s the chaos:

  • ​​PROS​​: Zapped hundreds of tiny flies and moths—felt like victory!
  • ​​CONS​​: Beetles treat the zapper like a disco ball. They buzz around it, ​​ignoring the light​​, and keep munching my crops. Worse—the zapper’s sparking scared my seedlings!

Bug zappers = beetle fail. They’re drawn to scent, not light! I lure them with ​​fermenting banana traps​, drown in soapy water.

Zappers killed my ​​precious lacewings! Switched to ​​kaolin clay sprays, beetles hate the chalky film.

June beetles dgaf about UV! I blast ​​old-school rock music​ at night—vibrations freak them out.

Manual picking at 5 AM works but is soul-crushing. Zappers just add noise pollution. @SafePawsOnly, kaolin clay washed off in rain—any fixes?

Beetles see ​UV-insensitive wavelengths​! Use ​green LED traps​​ instead, they’re sensitive to 520nm! @CatCareGuru, music theory for pest control? Brilliant.

@SafePawsOnly Fruit flies drown too—double win!
