Victor Sonic Spike Mole and Gopher Repellent, 2 Pack

Effectively repels moles and gophers with sonic frequencies!

• Key Product Features
• Sonic pulses penetrate the ground every 30 seconds
• Operates in a circular pattern, approximately 95 ft in diameter
• Safe for use around pets when used as directed
• Spike covers up to 7,500 sq ft
• Each spike requires 3 "D" batteries (not included), rechargeable batteries not recommended

Be sure to insert the Spike into the soil so that the cap is flush with the ground to avoid tripping hazards and the chance of hitting it with a lawnmower. Effectiveness depends largely upon soil type: dry, sandy or peat soil does not conduct the sonic waves easily. Moist clay is the best conductor of sound.
