BORHOOD

Ultrasonic Pest Repellent Plug-in, Electronic Mouse Traps & Insect Repellent, Pest Control for Rodent, Roach, Ant, Squirrel, Spider, Bugs, Mouse, Rat, Bat for Home, Office, Warehouse Black 1 Pack

Why we love it
  • Humane pest deterrent.
  • Energy-efficient operation nightly.
  • Safe for kids and pets.
Main Highlights
  • Advanced Ultrasonic Pest Repellent: Upgrade your home defense with our modern plug-in device. Emitting variable sound waves (25kHz–65kHz), it offers a clean, humane alternative to traditional mouse traps and messy ant traps indoor. It functions as a highly effective rodent repellent and insect deterrent, helping to deter mice, rats, squirrels, bats, cockroaches, spiders, and ants from settling in your living spaces.
  • Wide Indoor Home Protection: Designed to help manage a pest infestation in expansive open areas, this mice repellent indoor unit is ideal for kitchens, living rooms, basements, and garages. Because ultrasonic waves cannot penetrate solid walls or heavy furniture, we highly recommend using one rodent repellent indoor plug per enclosed room. Ensure it is placed 10–50 inches above the floor for optimal sound dispersion.
  • Three Smart Modes for Custom Deterrence: Tailor your home defense with 3 specific settings. The quiet Pressure Wave and Ultrasonic modes serve as a daily mouse repellent and help manage creeping bugs. The third setting emits a sharp, audible sound for stubborn issues—please use this powerful squirrel repellent and rat deterrent mode only in uninhabited spaces like attics or when you are away from home.
  • Energy-Efficient & Hassle-Free: Forget about constantly monitoring a rat trap or replacing sticky roach traps indoor. Consuming only 3–5W of power, this device uses less energy than a standard nightlight. Simply connect the included adapter into an outlet for 24/7 continuous operation. You can easily check the active mode and working status via the smart, clear LCD display.
  • Family & Pet-Friendly Design: Providing a cleaner, trap-free solution for your indoor home, this device is designed to be used around children, dogs, and cats (Note: do not use around pet rodents like hamsters). Patience is key: It typically takes 3-4 weeks to see complete results. An initial increase in bug or rodent activity during the first week is completely normal as they are forced to leave their nests!
