The Victor M793 Ultra Sonic Pest Chaser is an ultrasonic rodent repellent designed to deter mice and other rodents using high-frequency sound waves.

The varying ultrasound frequencies and volumes, peaking at 100db and ranging from 32 to 62 kHz, are intended to confuse and repel rodents effectively. Users typically notice a reduction in rodent activity within 6-10 days, which suggests a reasonable level of effectiveness relative to other products in this category. However, its effectiveness can vary based on the environment and the extent of the infestation. The device is also safe for humans and pets, except for those that are rodent pets like hamsters.

The product's coverage area isn't specified, which could be a drawback if you need to cover a larger space.

The Tomcat Rodent Block Expanding Foam Barrier is designed to effectively prevent mice from entering your home by filling gaps and cracks with a pesticide-free foam. One of its key strengths is its safety feature, as it is non-toxic, making it suitable for households with children and pets. The foam expands to create a durable and airtight seal, which can be applied both indoors and outdoors in areas like garages, attics, and basements. Since it can be trimmed, sanded, and painted over, it offers a seamless finish that won’t detract from the appearance of your home.

There are some considerations to keep in mind. While the product is effective for blocking entry points, its performance largely depends on how well the gaps are filled. Users need to be diligent in locating and applying the foam to all potential entry points for maximum effectiveness. Additionally, while the foam has a long-lasting bond, environmental factors could affect its longevity over time, especially if exposed to the elements. Some users might find the application process tricky, as it requires precision to avoid over-expansion or messy applications.

This product is suitable for homeowners seeking a safe and non-toxic solution to keep mice out, but it requires careful application and ongoing monitoring.
