Repellents / Ulrasonic & Sonic Repellers

Bark Free

Bark Free has a specially designed sound selector that lets you choose ultrasonic frequencies which can only be heard by dogs and cats, or lower sound tones audible to human ears. Bark Free uses an old age principle of "Negative Reforcement using Sound" to help train dogs to stop annoyance barking.

Transonic IX-L

Intense, variable pitch ultrasonic and sonic sound waves repel pests and small critters. This noisy, hostile, dynamic sound environment is intolerable to pests, yet friendly to pets, humans and the environment.
