Do Mouse and Rat Repellents Work? back to Homepage


Do Peppermint Oil, Moth Balls, Sonic Devices or other Mouse and Rat Repellents work?

The short answer is no. Despite the frequency with which these solutions are suggested on the internet there is little scientific evidence to support their efficacy.

In fact, the Internet Center for Wildlife Damage Management, a university based organization whose mission is to “consolidate existing and future information on integrated pest management (IPM) in wildlife damage management,”  has conducted extensive research on the topic of mouse repellents and states that there are “No effective ones known, including sonic devices.” This includes, Peppermint Oil, Moth Balls, Dryer Sheets, ultrasonic devices and other heavily promoted herbal type pouches and remedies.

The only recognized, effective solution for preventing and controlling a mouse or rat infestation is a three step process consisting of:

  1. Exclusion: Thoroughly inspect your home from top to bottom looking for gaps 1/4″ or larger. If a pencil eraser can fit through it so can a mouse. Look high and low. Mice can jump 12″ vertically and can climb straight up any rough surface such as bricks and siding. Pay attention to the following areas:
    • Sill – the area where the walls meet the foundation.
    • Pipes – gaps often exist around pipes (air conditioning, gas, water, etc.) which enter the building.
    • Eaves – gaps occur at the soffit level. Remember, mice can climb!
    • Doors – be sure that the gap between a door and the floor is filled with stiff brush or other gap filling product.
  2. Sanitation: This includes good housekeeping practices and proper storage and handling of food materials, feed, and garbage. Bulk food should be stored in rodent proof containers and the perimeter of buildings and other structures should be clean of weeds and debris (including stacked lumber, firewood, and other stored materials) to discourage rodent activity.
  3.  Population Reduction: If an infestation already exists, some form of population reduction is almost always necessary. This can be accomplished with traps or baits.
