While wasps can be a nuisance, they are beneficial to the ecosystem as pollinators and a form of natural pest control. There are several ways to repel wasps without killing them, such as using natural repellents like mint, citrus fruits, or peppermint oil, or creating a homemade spray with vinegar and water. Another method is to use electronic insect repellents, which emit high-frequency sound waves to deter insects. However, the effectiveness of these devices is debated, with some studies showing they may not work as well as claimed.

What You'll Learn
High-frequency sounds are used to deter pests
High-frequency sound repellents are often marketed as a safe, nontoxic, and environmentally friendly solution to deter pests such as wasps. These electronic devices emit ultrasonic sound waves that are inaudible to humans but may be perceived by certain insects. The idea is that pests will avoid areas where these high-frequency sounds are present.
While these sound repellents are widely available, there is insufficient scientific evidence to support their effectiveness in deterring pests. Studies have been conducted to test their efficacy against various pests, including cockroaches, ticks, ants, mosquitoes, and rodents, but the results have been inconclusive. For example, a study reported in Insects in 2021 found that ultrasonic devices only repelled 19.5% of ticks, leading researchers to advise against relying on sound repellent products for tick bite prevention.
Despite the lack of scientific evidence, some users have reported success with ultrasonic pest repellers. These devices are plugged into electrical outlets or battery-operated and emit high-frequency sounds intended to disrupt pest behaviour. It's important to note that the Federal Trade Commission (FTC) has issued warnings to manufacturers of these devices, stating that their claims of efficacy must be supported by scientific evidence.
To effectively use sound repellents for pests like wasps, it is recommended to place the device in an optimal location, adjust the sound volume and frequency according to the instructions, and ensure it is protected from moisture and extreme temperatures. Additionally, it's worth exploring alternative methods for pest control, such as natural repellents like mint plants, citrus fruits, or peppermint oil, which can help deter wasps without the need for electronic devices.

There is insufficient evidence that high-frequency sounds repel or kill wasps
For example, a study reported in Insect Science in 2006 tested three commercially available sound repellents against the German cockroach, and there was no evidence that they were successful. Similarly, researchers tested 19 different ultrasonic devices against the female tick Ixodes holocyclus in a study published in Insects in April 2021. The results showed that the sound repellents only repelled 19.5% of the ticks, leading the researchers to conclude that they could not recommend sound repellent products for preventing tick bites.
The Biocontrol Network has stated that it would take years and significant financial resources to test the effects of electronic pest control devices on even one household pest group, such as wasps. Despite this, many users have reported success with ultrasonic pest repellers, and some products on the market claim to emit high-frequency sounds that wasps dislike. However, manufacturers' claims are often not supported by scientific testing, and safety concerns have been raised about the potential impact of these devices on telephone conversations, burglar alarm systems, and hearing aids.
While electronic insect repellents that emit high-frequency sound waves may seem like an attractive option for wasp control, the lack of scientific evidence supporting their effectiveness suggests that they may not be a reliable solution. Homeowners with pest problems are advised to consult qualified inspectors who can provide practical and effective solutions tailored to their specific situation. Additionally, there are other non-electronic methods to repel wasps, such as the Waspinator, a nest-shaped bag that testers say will repel wasps without the use of chemicals or electricity.

Ultrasonic pest repellents emit sounds inaudible to humans
Ultrasonic pest repellents are small electronic devices that emit high-frequency sound waves to deter pests. The sound waves are typically above the range of human hearing, making them inaudible to people but disturbing to certain pests. These devices claim to create an environment that pests find uncomfortable, encouraging them to leave or avoid the area.
The devices are primarily marketed to repel rodents such as mice and rats, but some also claim to be effective against insects like cockroaches and mosquitoes. However, there is insufficient scientific data to support the effectiveness of these devices. Studies have shown that while some pests may be bothered by the noise, they can quickly become accustomed to it as they realize it is harmless.
Furthermore, the sound waves produced by these devices can have unintended consequences. For example, the sound may interfere with telephone conversations, burglar alarm systems, and hearing aids. It can also cause distress to certain pets, such as rabbits, guinea pigs, and hamsters, which are capable of hearing ultrasonic frequencies.
While ultrasonic pest repellents may seem like an attractive option for nontoxic and environmentally friendly pest control, the lack of scientific evidence supporting their effectiveness suggests that consumers should approach these products with caution.

Some people can hear ultrasonic pest repellents
Ultrasonic pest repellents are small devices that emit high-frequency sound waves to repel or scare away insects and rodents. These sound waves are typically above the range of human hearing, but some people with acute high-frequency hearing may be bothered by the sounds emitted by these devices. While ultrasonic pest repellents are marketed as safe and effective, there is limited scientific evidence to support these claims.
Ultrasonic pest repellents are designed to create an environment that pests find uncomfortable, encouraging them to leave or avoid the area. The devices are primarily marketed to repel rodents such as mice and rats, but some also claim to be effective against insects like cockroaches and mosquitoes. However, studies have shown that these devices have limited to no impact on most pests, including rodents and insects.
Some research has indicated that ultrasonic sound can be harmful to certain species, causing increased body temperature or audio-induced seizures. However, these findings have not been replicated in real-world settings. Researchers using higher-quality ultrasound generators have shown that sound can disrupt the mating or eating habits of particular animals, but these generators are far more advanced than any commercially available devices.
The use of audible sound to deter pests is not a new concept. The ancient Chinese, for example, used mechanically operated sensory-repellent devices to deter rodent infestations in agricultural crops and buildings. While ultrasonic pest repellents may seem like an attractive, non-toxic solution for pest control, there is currently insufficient evidence to support their effectiveness.

Alternative wasp deterrents include vinegar and citrus
While there are electronic insect repellents that emit high-frequency sound waves to deter wasps, there is insufficient scientific evidence to support their effectiveness. These ultrasonic devices are safe and non-harmful, but studies have shown that they are not a reliable method to repel pests.
To make a vinegar-based wasp trap, you can use a recycled bottle and fill it with a DIY vinegar solution. Poke two holes in the bottle, opposite each other, and tie a string through them to hang the trap. The vinegar solution can be made by mixing apple cider vinegar, apple juice, water, sugar, and a few drops of dish soap. This trap will help to prevent wasps from nesting in your home.
In addition to vinegar, certain scents like peppermint, cloves, and citrus can be used to deter wasps. Placing cloves into an orange or lemon and hanging them near outdoor dining areas can help keep wasps away. The strong clove fragrance, combined with the citrus scent, creates an uninviting environment for wasps.

Frequently asked questions
There is no scientific evidence that high-pitch sounds effectively kill wasps. However, some ultrasonic devices in the market claim to repel or deter them.
Ultrasonic pest repellents emit high-frequency sounds that are disruptive to pests. The sound causes a physiological response known as audiogenic seizure response, which can lead to non-directional running, convulsions, and possibly death from cerebral hemorrhage.
Laboratory tests have shown that most ultrasonic pest repellents do not work as advertised. There is insufficient scientific data to support their effectiveness in repelling or killing pests.
Some alternative methods to get rid of wasps include using natural insect repellents, hanging a fake wasp nest outdoors, or spraying a mixture of vinegar and water around areas where wasps have been spotted.
Wasps are attracted to sweet smells, garbage, and standing water. To avoid attracting them, keep garbage cans properly sealed, avoid standing water, and be cautious of sweet smells from flowers or fruit trees.
