P7900  Sonic Molechaser ® 

KEEP BURROWING RODENTS OUT OF YOUR GARDEN FOREVER! 

The Sonic Molechaser ® is the most humane and environmentally friendly way of keeping 

gardens and lawns free of destructive ground rodents. 

Most underground rodents have poor eyesight, yet nature has given them a very acute 

sense of hearing and sensitivity to ground vibration.  The Sonic Molechaser ® exploits 

this sensitivity to produce a penetrating sonic sound of 300Hz over an area of approx. 

11,250 sq. ft. (1/4 Acre) at 15 second intervals.    

Sonic Molechaser ® is completely harmless to worms and other underground bugs. 

y

  Sonic Molechaser ® operates in a circular pattern, approx. 120 ft. in diameter.  This 

must be an unobstructed 120 ft. 

y

  Place Sonic Molechaser ® at site of worst rodent infestation. 

y

  Remove Sonic Molechaser ® if ground freezes or when flooding occurs. 

y

  Replace battery after approximately 4-6 months or when sound is no longer audible.

IMPORTANT : 

1.  Top cover of Sonic Molechaser ® must be tightened again  

after insertion into the ground  so there can be no possibility  

of water damage. 

2.  Make a pilot hole before inserting Sonic Molechaser ® into  

hard ground.  *DO NOT HAMMER OR PUSH EXCESSIVELY  

OR YOU MAY DAMAGE UNIT. 

3.  Range of effectiveness depends largely upon soil type : Dry,  

sandy, or peat soil does not conduct the sonic waves easily  

and sometimes two Sonic Molechaser ®s may be required.   

Moist clay is the best conductor of sound.
