STV have produced a wide range of pest control systems & weatherproof baits for a wide range of unwanted guests in & around your home or work place. Moles are becoming more apparent just not in rural areas but in common back gardens. These little pests can do serious damage to the most well maintained garden. So that your hard work is not in vain STV have produced the STV646 mole repeller. This simple to install unit will just push in to the soil & will send a sonic pulse & vibration through the ground every 25 seconds to prevent the moles from staying & keep them on the move. The STV646 mole repeller will easily protect an area up to 1000 square metres. There is No requirement to exclude children & pets from the protected zone area as the unit is welfare-friendly & is just a deterrent that does not harm moles.
