Rat Repellent FAQs

Where Should I Use Rat Repellent Sprays?
Repellent sprays should be used in areas where you’ve seen rat activity. Depending on the ingredients in the spray, you may be able to apply the product anywhere in your home. Safe, non-toxic sprays can be used on doorways, windows and other potential entryways to keep rats out.

Keep in mind that sprays will need to be reapplied every few days. Otherwise, they start to lose their potency. Read the product directions on how often to reapply the product. Most will have directions on how to use the product to keep rats away.

How Do Ultrasonic Devices Repel Rodents?
Ultrasonic repellents use sound waves to keep rodents away. Ultrasound is a spectrum of sound that’s just beyond our hearing range. Rats and some other animals can detect ultrasound at varying frequency ranges.

Rats and other rodents are nocturnal creatures, but their night vision is poor. They rely on ultrasound for communication. Ultrasonic devices use ultrasound waves at different frequencies to confuse and disorient rats. It also interferes with the ultrasound signatures of natural predators.

These effects will send rats running the other way – away from your home.

Ultrasonic devices do not affect pets, although it will affect some other wildlife. If you have cats and/or dogs, they should not be bothered by the ultrasonic sounds.

How Long Does it Take for Repellents to Work?
The amount of time it takes repellents to work will depend on the type of product you use. If you’re using a spray or specialty insulated tape, the results will be immediate. Because these products rely on scent, they should start working immediately.

If you’re using an ultrasonic repellent, however, it may be 2-3 weeks before the rats stay away for good. And you may see more rats before they disappear completely. For more immediate results, you can combine an ultrasonic device with a spray.

How Long Do Repellents Last?
If you’re using a spray repellent, you’ll need to reapply it every few days, especially if you’re using it outdoors. You’ll need to be diligent and consistent if you want this type of repellent to provide continual results.

If you’re using an ultrasonic repellent, the results will last as long as the device is plugged in and working. They provide continual, uninterrupted results as long as it has power.

Keep in mind that not all repellents work for every rat. Some rats will respond well to sprays, while others are more affected by ultrasonic waves. Some people need to use a combination of the two to repel rats, so you’ll need to be persistent if you want to win the fight against these rodents.

Will a Rat Repellent Kill the Nest?
No. Repellents will not kill rats or their nests. Depending on the type of repellent used, there is a possibility that it might kill a single rat, but that’s not what these products are designed to do.

If you have a serious infestation, you’ll need to trap the rats, use a home remedy or call an exterminator to destroy the nest.

Conclusion

No one wants rats anywhere near their homes, but not everyone wants to deal with dead rats either. Repellents can keep rodents away without killing them, so you can tackle your rat problem without putting your family at risk.
