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?
Canadian registration
In Canada, a pest control product carries a PCP registration number on its label. Every product here has one, ultrasonic devices included.
Indoor or outdoor
Ultrasonic units go inside. The 2 spray listings name outdoor surfaces such as siding, fences, posts and garbage cans.
Room size
Victor's Super PestChaser is made for attics, basements and garages; the small plug-ins are for one room.
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.
