What Are The Different Types Of Rat Repellents?

There are 2 types of rat repellents in this collection.

  • Repellent sprays

    Doktor Doom and Tomcat sprays use denatonium benzoate (Bitrex), a very bitter substance, to keep rodents from chewing and gnawing.

  • Ultrasonic repellers

    Plug-in or battery units that send a high-frequency sound people cannot hear. Their makers say the sound does not go through walls or furniture: one unit per room, or per floor for the battery model.

What Should You Look For In A Rat Repellent?

  1. Canadian registration

    In Canada, a pest control product carries a PCP registration number on its label. Every product here has one, ultrasonic devices included.

  2. Indoor or outdoor

    Ultrasonic units go inside. The 2 spray listings name outdoor surfaces such as siding, fences, posts and garbage cans.

  3. Room size

    Victor's Super PestChaser is made for attics, basements and garages; the small plug-ins are for one room.

  4. Power

    Plug-in units need an outlet; the PestContro unit runs on batteries.

How Do You Use Rat Repellents?

  • Read and follow the label of every product.
  • Repellents aim to keep rats away; they do not remove rats already inside. For those, see our [rat traps](/collection/rat-traps).
  • Block the gaps rats use to get in: see our [rodent proofing](/collection/rodent-proofing) products.
