Garden pests can be a major problem for many gardeners, causing damage to crops, plants, and flowers.
While there are a variety of chemical-based pesticides available for pest control, these products can be harmful to the environment and pose health risks to humans and animals.

Fortunately, there are a variety of natural repellents that help to keep garden pests at bay without resorting to use of harmful chemicals. These include:
Companion planting as a natural repellent
This is one of the most effective natural repellents for garden pests. It involves planting certain plants together to help repel pests or attract beneficial insects that will prey on pests.
For example, planting marigolds near vegetables such as peppers and tomatoes can help to repel aphids and other insects while planting mint near cabbage can help to repel cabbage moths.
Similarly, planting dill and fennel near tomatoes can attract beneficial insects such as ladybugs and lacewings which will eat aphids and other harmful insects.
Essential oils that are pest repellant
Certain essential oils such as peppermint, citronella, and garlic oil, can be effective at repelling a wide range of insects and other pests.
These oils can be diluted and sprayed directly onto plants or used in a diffuser to repel insects in the garden.
For instance, peppermint oil can be mixed with water and sprayed onto plants to repel aphids, while citronella oil can be used to repel mosquitoes and flies.
Netting as a natural way to repel pest
Physical barriers such as netting, fencing, and row covers can also be effective at keeping pests out of the garden. These barriers can be particularly effective at protecting crops from larger pests such as deer and rabbits.
Netting can be used to protect fruit trees and berry bushes such as boysenberries, while fencing can be used to protect the entire garden from deer and other larger animals.
Good garden hygiene helps repel pest
It is also important to maintain good garden hygiene to prevent pests from invading your garden plants. This includes removing dead leaves and debris from the garden and keeping the garden well-watered and weeded.
Do pest repellents really work?
When it comes to pest repellents there are many different types of products available in the market, ranging from natural repellents such as essential oils and plants, to chemical-based repellents and traps.
While some of these products may have a limited effect on certain pests in certain conditions, the overall effectiveness of pest repellents is still a topic of debate among experts.
Natural repellents in the market
Some natural repellents such as certain essential oils have been found to have a modest repellent effect on certain pests in laboratory or field settings.
For instance, peppermint oil has been shown to repel certain species of ants and spiders, while citronella oil has been shown to repel mosquitoes and flies.
Similarly, certain plants, such as marigolds and lavender, have been found to repel certain insects when planted in the garden.
Resistance to natural repellents
Many pests have developed resistance to natural repellents over time and the effectiveness of these products varies depending on factors such as the species of pest, the concentration and formulation of the repellent, and the environmental conditions.
Effectiveness of pest repellents
While some natural repellents may have a limited effect on certain pests in certain conditions, the overall effectiveness of pest repellents is not well-established.
Pest management requires a multifaceted approach that may include sanitation, exclusion, and the use of pesticides, traps, or other control measures in addition to repellents.
It is important to consult with a pest management professional to develop an effective and safe pest control plan for your specific situation.
Do electronic rodent repellents really work?
Electronic rodent repellents are devices that use ultrasonic or electromagnetic waves to repel rodents such as mice and rats.
While the idea of using a device to keep pests away may sound appealing, the effectiveness of these devices is a topic of debate among experts.
Studies on effects of electronic repellents
Some studies have shown that certain types of pest repellents such as ultrasonic devices may have a limited effect on certain pests in certain conditions.
For instance, a 2002 study published in the Journal of Economic Entomology found that ultrasonic devices had a modest repellent effect on German cockroaches in laboratory settings, but the effect was not significant enough to be practical in a real-world environment.
However, other studies have shown that many pest repellents are ineffective and are a waste of money for users.
For instance, a 2013 study conducted by the University of Arizona in a large apartment complex found that ultrasonic devices had no effect on pest control.
While some pest repellents may have a limited effect on certain pests in certain conditions, there is little evidence to suggest that they are a reliable and effective method of pest control.
What are the side effects of ultrasonic pest repeller?
Ultrasonic pest repellers are electronic devices that emit high-frequency sound waves to repel pests such as rodents, insects, and spiders. While these devices are generally considered safe for humans and pets, there are some potential side effects to be aware of.
Discomfort and irritation of ultrasonic pest repellent
One of the main concerns with ultrasonic pest repellers is that they may cause discomfort or irritation to some people and animals.
The high-frequency sound waves emitted by these devices can be audible or even painful to certain individuals, especially those with sensitive hearing or hearing impairments.
Additionally, some pets such as dogs and cats may be sensitive to the sound and may become agitated or anxious in the presence of an ultrasonic pest repeller.
Frustration in use of ultrasonic pest repellent
Another potential side effect of ultrasonic pest repellent is that they may not be effective at repelling pests, which can lead to frustration, waste of time and money for users based on studies cited above.
It is therefore important to weigh the potential benefits and risks of using an ultrasonic pest repellent and to consider other pest control methods as well.
