Sweeney’s® Sonic Spike™
Safely send moles and gophers scurrying from your yard unharmed with this easy-to-use mole and gopher spike. When placed in the ground and activated, sonic pulses penetrate the soil, emitting a sound which is highly irritating to moles and gophers who are virtually blind and overly sensitive to sound and vibrations. Climate permitting, leave the sonic mole and gopher repeller in the ground to repel new generations of pests.
The mole and gopher sonic spike is designed with a convenient removable battery sleeve for trouble-free battery replacement. A Spike will work for 4 – 6 months on one set of alkaline batteries*. Spike must be used continuously for 7-14 days before moles and gophers start to move away from the area.
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.
*Spikes use 3 "D" cell batteries, not included.

How to Use
STEP 1-To open, unscrew YELLOW cap counter-clockwise.
STEP 2-Remove battery cartridge and insert 3 "D" cell batteries. Re-insert the battery cartridge into the Spike. If battery installation is correct, you will hear the first vibrating sound within 15 seconds.
STEP 3-Tighten the cap securely to keep moisture out.
STEP 4-Use a wooden or steel rod to make pilot holes prior to inserting the Mole & Gopher Sonic Spikes™. To prevent damage, do not hammer the Spike into the ground.
STEP 5-Insert Spike until the bottom of the cap begins touching the ground.
STEP 6-Insert Spike all the way into the ground. This will prevent the chance of hitting it with a lawnmower. Be certain to insert the Spike so that the cap is flush with the ground. If it protrudes an inch or two it could be a tripping hazard. Remember whrere the Spike is located so it may be removed for battery replacement.
STEP 7-Remove Sonic Spike™ when flooding may occur or before ground freezes.

We have a severe problem with moles. I've had them pop up just after mowing a spot. I get turned around and there it is. They nest in the trees next to one lawn area and have terrorized the lawn. I put a spike here just before growing season and to date, not a single mole. The next area is very large and more than the 95 ft specified. I put a spike in the middle with about 95% success. The first mole that popped up was exactly on the stick. I believe there is one in the nest that suffers with tinnitus. Other than that I'm extremely satisfied.

Thank you for sharing your experience with the Sonic Spikes. We are happy to hear how well they have worked to keep the pesky moles out of your yard. Moles are curious creatures, so they may occasionally dig tunnels closer to the spike to investigate where the sound is coming from. After a few days of hearing the constant buzzing, they will typically look for quieter places to live.
We hope that you continue to have success with these spikes in your yard. If you have questions or need additional assistance, please do not hesitate to contact our Consumer Relations Team at 1 800 800 1819 x458.
Amazon Review, I love this productNovember 22, 2013
This product delivers what it say's it does! I have no more gopher problems! Just wish the batteries didn't cost so much!!
Amazon Review, Very effective productNovember 04, 2013
Reviewer: J. House
These work very well with long battery life. We have sandy and rocky soil and within a few days activity moves away from our yard. The units will also keep ground squirrels and skunks away from out buildings.
Amazon ReviewNovember 02, 2013
Reviewer: Thomas E. Culhane
A new house was constructed next to ours two years ago and all the moles moved from that lot to our lawn and garden. I got fed up with bombs and poison as they seemed fairly worthless. Saw these at the big box store and thought I would give them a try. Frankly, I would have not bought them had I read all the negative reviews here first. But they have worked well for me the last four months. Have not seen a new mole hill within 30 feet of either device since installed! I used a piece of aluminum pipe of same diameter pounded into the ground to hollow out a pilot hole. So the spike fit very snugly into the ground. I believe that might be the key to successful use of these devices. More sound energy gets transmitted into the ground if the spike fits snugly. Use a stethoscope to check to make sure the batteries are still OK once every two weeks. Couldn't be more pleased with the results.
Amazon ReviewOctober 29, 2013
We have a major mole problem in our yard and have to have these all of the time. We cannot use pesticides because they are bad for the environment and we have indoor/outdoor pets. They work really well but we do have to replace them usually about once a year, usually because my husband whacks them with the weed eater:(

Reviewer: Eric Nielsen
My three lawns were covered with excavated mounds of soil. Two weeks after installing two stakes on opposite sides of each lawn was no more evidence of gopher activity. The backyard lawn is 50 feet wide by 30 feet deep.

Reviewer: Deborah Jordan
I have to admit, I was not expecting much.... But I am very pleased with my little spikes....3 weeks later and the dirt mounds are gone, the grass is growing again, and the little stinkers seem to be gone.!!!i.I would recomend this treatment to anyone who does not want to mess with the poision, or to try to actuall catch them!!
Amazon Review, Great for the gardenSeptember 04, 2013
The sonic pikes work great without the danger of chemicals around my pets. I very highly recommend them for any yard.

Reviewer: farmer marv
These spikes were very easy use. I had a groundhog move in under our deck and think it was his new home. After putting a spike in the ground under there about 3 weeks ago I haven"t seen him since. Tried poison didn't work. Tried hot pepper sauce didn't work. Tried traps didn't work. Sweeney's 9012 sonic spikes are the first thing that worked so they get 5 stars. Even have less ground squirrels around now as a bonus
Helpful hints for SpikesSeptember 25, 2014
My spikes worked but it takes longer than 5 days. It took about 21 days to work. What would help if the company showed how to setup the spikes up (ex. how fare apart and locations). Also you must move them as the gophers start to leave. The hardest thing is to get the spikes in the ground. It would be very helpful if they had a tool go with it. Good Luck

The Sonic Spikes™ must be used continuously for 7-14 days before ground rodents begin to move away from the area. The setup of the spikes at each property will vary based on the size of the area you are looking to cover and any obstructions that may block the signal. Each individual spike will cover up to 7,500 sq. ft. The sound is projected out from the spike in a circle with an approximate diameter of 95 ft.
It is very important to create pilot holes in the soil before inserting the spike. We recommend simply using a wooden or steel rod (or stake) to create the pilot holes. We hope you found this information to be helpful. We appreciate your feedback and have shared it with our Product Managers. If you have questions or need additional assistance, please do not hesitate to contact our Consumer Relations Team at 1 800 800 1819 x458.
After trying various methods I noticed the Sonic Spikes at Lowes. Purchased one and it worked in the worst area of my yard. Just purchased two more for my yard and will recommend product to my neighbors

Reviewer: beyond the end of nowhere "JD fan"
works well as far as functioning - gophers do seem to go further away from spike areas....I like the fact that it does not kill the animals, and is not harmful to my pets in any way....good humane way to discourage moles.
Amazon Review, Working as promisedNovember 21, 2013
Reviewer: jon turley
Seem to be encouraging the gofers to move on. In my soil (sandy clay with rocks) I needed another set to cover the property.

Reviewer: Cecilia Guarino
I found this to be the only deterrent that worked on keeping moles our of our back yard. I used 4 across the lawn, and replace the batteries every 6 months. One of the units no longer functioned after 12 months, but the manufacturer replaced it free of charge on the warranty.

Reviewer: Husband Rob AGAIN!!!
The best battery operated sonic mole resistor I've found. Long lasting & durable. Reasonably priced too. I purchased a 2nd pair after trying the 1st.
Amazon ReviewApril 27, 2013
Reviewer: M. Williams
Wow, I'm quite surprised at all the negative reviews. We've been keeping those little varmint's at bay for over 4 years now using sonic spikes. I use 8 of them most of the time and the batteries will last the entire summer without a problem. Every now and then you'll get a mole wanting to venture onto our property. They will never come in that far at all before they turn around and find a more peacful suitable/quieter grounds to dwell in. The only thing I recommend and what I do is place a small wire flag (the kind they use to mark buried cable with) next to the trap, just so you can locate them easily in the late fall or the grass happens to grow over them. The only reason they received 4 stars instead of 5 is the price. Other than that we've been happy with the results hands down.
