The Singing Bottle is a natural mole repellent that is very easy to implement. This method doesn’t cost anything other than your time … and is very friendly to animals and the environment. Unfortunately this method does not always work … especially in areas that have longer periods without wind. In many cases it makes sense to combine Singing Bottles with professional sound devices.
How does the “singing bottle” act as natural mole repellent?
The basis of this natural mole repellent is the fact that rodents are naturally sensitive to sound and vibrations. The sound is generated by the wind that blows over open bottles. While this sound is not very loud to the human ear … it travels underground if the bottles are buried about halfway into the soil. This sound puts off the rodents … causing them to avoid the area.
Any size of glass bottle can be used … though the smaller the bottle is … the easier and faster they are to bury in the ground. For your “Singing Bottle” to act as an effective natural mole repellent it is important to place it as straight (vertical) as possible into the ground. (Otherwise it won’t “sing” as well.)
As for other sound-based vole and mole repellents … the protected area is a circle around the bottle. There are many factors that determine how far you need to space the Singing Bottles … for more details on this subject see sections 2 and 3 in our article on sound devices: “Method 7: Can sound devices near vole holes get rid of the animals?“)
How well does this method work?
The effectiveness of this natural mole repellent depends on a number of factors:
- Type of soil: The denser and heavier the soil … the better the sound travels underground … and the better this method will work.
- Strength & frequency of wind: As you may expect … the stronger the wind and the more often it blows … the better this method works. At the same time, you do not need a strong breeze every day.
- Number & spacing of bottles: As mentioned above, this is always important.
In conclusion, you will not fully know how well this method works until you have tried it out.
A much more reliable (if much more expensive) vole and mole repellent are purpose-built sound devices reviewed on our dedicated page: Method 7: Can sound devices near vole holes get rid of the animals?
In many cases, it makes sense to combine Singing Bottles with at least a few other sound or vibration devices. That way, you still benefit from the zero cost of the bottles … but also have a much better reliability of your mole and vole control efforts … especially in periods of low wind.
Is this method expensive?
No. All you need are old glass bottles. (Plastic bottles don’t work as well.)
How much effort does this method involve?
Burrying a bottle half way into the ground is fast and easy to do. Everything will depend on how many bottles you need to put into the ground.
Long-term, this natural mole repellant is little effort. All you will need to do is to pour out the rain water that will have collected in there over time. It takes a long time for the bottles to fill up … as the opening is quite small. In most cases, the Singing Bottles only need to be emptied once a year or so. It’s best to do this when the soil is wet … and the bottle can be easily pulled out of the ground and put back afterwards.
Environmental, animal and safety matters
This natural mole repellant is one of the most environmentally friendly methods. Unlike many other methods … no voles, moles, gophers, or other animals and plants are harmed.
There may be a risk if children pull the bottles out of the ground and break the glass.
Summary of pro’s and con’s
- No/low cost
