Question
I’ve got voles on my lawn and I’d like to get rid of them. A neighbor advised me to put mothballs in their holes. Does it work?
Answer
The use of naphthalene, commonly known as mothballs, is a method sometimes recommended by word-of-mouth. However, this approach is far from a miracle solution. Inserting mothballs into holes dug by voles only encourages them to move around and create new tunnels, without eliminating them from your garden.
Naphthalene is not only useless, but toxic, harming other animals and useful wildlife, and posing risks to human health. Ingestion by domestic or wild animals can cause serious health problems. It adversely affects beneficial insects and can contaminate soil and water.
Minimizing Impact
It’s important to recognize that voles are extremely resilient and prolific creatures, capable of adapting and multiplying rapidly in a variety of environments, whether urban or rural. Their ability to reproduce at a sustained rate makes total eradication of these rodents from your property virtually impossible.
Nevertheless, there are strategies to minimize the visual impact of the damage they cause to your lawn. One of the simplest and most effective techniques is to fill in the tunnels and holes left by field mice with quality soil, then reseed these areas with a suitable grass seed mix. This approach not only masks the signs of vole activity, but also helps to regenerate and beautify your lawn. In just a few weeks, signs of voles invasion become invisible, allowing your garden to regain its aesthetic appeal and health. Adaptation and proactive damage management are the keys to maintaining an attractive, lively green space, despite the inevitable presence of these little inhabitants of nature.
Other Strategies
Alternatively, to ecologically reduce voles in the garden, encourage natural predators such as birds of prey, by installing perches. Use natural repellents (e.g. garlic or aromatic plants) and consider trapping with specific devices, taking care not to harm other animals. Physical barriers, such as buried barriers, can protect vulnerable areas.
