Simple operation: plug into a standard AC outlet and the unit begins working when the blue indicator light is on. Low maintenance: no traps, chemicals, or refills required. What it does Emits ultrasonic waves at changing frequencies to stimulate pest sensory and nervous systems, making living spaces less attractive to pests such as mice, spiders, and common crawling insects. Designed for continuous indoor use to reduce pest activity over time.

Expected timeline 35 days: pests disturbed from hiding locations and begin to move away. 23 weeks: noticeable reduction in pest activity for many situations. About 1 month: further reduction depending on infestation size and environment. Practical applications Home: kitchens, basements, attics, garages to reduce mice and common crawling insects. Commercial: warehouses, offices, and hotel storage areas to supplement existing pest control measures. Retail and storage: supermarkets or grain storage areas where nonchemical, continuous control is preferred. Tips for effective results Use one unit for each room or area to avoid shadow zones. Avoid blocking the front of the device with furniture or drapery. Combine placement near entry points and known pest pathways for faster impact. This repeller provides a nonchemical, plugin option to help reduce pest presence in indoor spaces. Results vary with pest type, infestation level, and placement.
