Buying Guide

Match device type to location

Choose plug-in units for rooms and garages, and vehicle-specific models for under-hood or storage protection

Check targeted pests

Look for units labeled for mice, roaches, spiders, or general insects to ensure the frequency modes address your pest problem

Evaluate coverage and pack size

Larger homes benefit from multi-pack units or multiple devices to cover separate rooms and entry points

Prefer adjustable modes or remote

Devices with multiple ultrasonic modes, adjustable frequencies, or remote control let you tailor output for rodents versus insects

Consider electromagnetic or strobe features

Electromagnetic outputs and strobe deterrents provide supplemental non-chemical options for cars and sheltered spaces
