Full Description: The 'GOPHER SONIC SPIKE' Actually works to rid your garden of Gophers and Moles. Has a 95' foot diameter range, needs no batteries as its solar powered and the best part is no pesticide or messy traps needed. Emits a sonic pulse every 30 seconds that irritates Gophers and Moles causing them to find a home somewhere else instead of your garden.
NOTES; Used these for some time now at our nursey and works great! The 95 foot range is less if there are obstructions like walls, many posts etc. and also smaller range on slopes depending on the soil compaction. Used about one year and seems durable enough so not sure how long it can hold up in weather/elements but been wet almost every day and still going. If Gophers are already present it takes about a week to 10 days to scare them off. Said to work in lawns too but havent tried it myself yet.
