How to Repel or Avoid Rats Naturally – 6 Easy Steps

Tuesday, June 3rd, 2014
  1. Carefully Seal the Rat Entry Points –

    This is first step you need to carefully implement. Rats can easily enter any hole if its head get through, so find these entry points and seal or close it. Sometimes, you may leave open the windows on your garden side, you should close it completely or use steel mesh if you want to leave it open.


  2. Grow Pepper mint plants or Try Oil

    Pepper mint plants are natural deterrents, you can grow some plants in your garden, somewhere very close to your back doors and windows. Also, you can try soaking peppermint oil to some cloth or cotton balls and place near the rat entry points, the strong smell will deter rats for a period of time.

  3. Have a Cat as Pet at Home

    If you are fond of cats, have one or two cats as pet at home. Cats are naturally predator to rats, once rats feels the presence of cats, it vanishes in jiffy.

  4. Place Ultrasonic Rat Repellers

    This is a simple & permanent of way of chasing rats from any closed areas. It produces high pitch, fluctuating noise in rat hearing range (Above 20kHZ), which is highly irritating, stressful, changes the behavioral pattern of rats and makes them flee. Just place a repeller in the rooms where you would like and make it Rat-Free-Zone. Please note, it is non-audible and safe to humans.
