Kindly allow me to contribute.

I've seen this thread earlier but hadn't had the time bec. of the holidays. Medyo forte ko itong topic not because magaling ako, but due to experience---> we have grain warehouses and feed mills in the province, and some businesses in the Tayuman/Bambang area (grabe daga dun dahil malapit sa Blumentritt Market).

  • Yung mga high tech gadgets (whether ultrasonic, electromagnetic, laser sword :p etc.) SIMPLY DO NOT WORK.

Rodent & pest control is truly a concern ng mga bodega ng grain and if they were truly effective, they would become industry standard equipment and see widespread use. Bilyonaryo na dapat mga nakaimbento niyan. A (relatively) small investment would save tons of money otherwise lost to pests & additional overhead. As far as I know, nobody in the business uses them. (May nag try, all disappointed)

The fact that they're still secret "magical" devices (with a but of pseudo-science thrown in) sold in whispers on the internet and TV shopping tells you a lot.


  • My answer's the same for scented "repellents" etc.

Hindi maarte & pa-sosy ang daga. Sila lang mabubuhay pag nag WW3. Pinag-aromatherapy mo lang sila, or assuming they don't like the smell, they will simply just go around it.


Alright, these things MAY have worked for some, on a small scale personal instance, but for the abovementioned reasons, I really don’t recommend them. Kasing effective lang ng magsabit ka ng anting anting or orasyon. (Note: not intended as a personal affront to anyone [sorry po], just stating from exp.) Sa amin, no one would stake $$$ in losses trusting these.
