Mosquitoes, Bugs & Rats Ultrasonic Pest Repellent 3 Modes Variable Frequency Ultrasonic Pest Repellent with LED Flashing, Indoor Insect Control Plug in Rodent Deterrent Repeller for Mice Mosquitoes Rats Roaches Bugs Bats Our advanced system emits variable ultrasonic waves that effectively target and disrupt the nervous systems of pests. This constantly changing frequency is key, as it prevents rodents and insects from becoming immune to the sound waves, ensuring your home maintains long-term protection against mice, rats, spiders, cockroaches, and mosquitoes. Unlike single-frequency devices, our technology remains effective season after season. Tackle any infestation with precision. Mode 1 provides daily protection against mosquitoes, flies, and crawling insects. Mode 2 intensifies ultrasound to combat mouse and rat problems, ideal for severe infestations in unoccupied spaces like attics, basements, and garages. Modes 3 & 4 unleash maximum power, with Mode 4 adding a potent LED strobe light for a dual-attack that drives away the most stubborn pests overnight. Achieve the best results by placing the device 12-20 inches (30-50 cm) above the floor, away from curtains and furniture. For open floor plans, large rooms, or severe infestations, we recommend using multiple units for complete coverage. It is normal to see increased pest activity initially—this is a positive sign that the ultrasound is effectively driving them out! This versatile plug-in design is ideal for countless indoor spaces: homes, apartments, kitchens, bedrooms, living rooms, warehouses, garages, offices, restaurants, and sheds. It provides 24/7 protection with minimal energy use. For best results, allow 3-4 weeks for a full cycle to clear existing pests, as this is a gradual process that disrupts breeding and drives them away naturally.
