Frequently Asked Questions

How does the Defentra Ultrasonic Rat Repellent work?

DEFENTRA uses variable ultrasonic frequencies to irritate rodents' auditory systems, plus flashing LEDs to disrupt their vision, making your engine bay uninhabitable for them.

Is the Defentra device effective against all types of rats and mice?

Yes, it is designed to be effective against common species of rats, mice, and squirrels that typically infest car engine bays. The variable ultrasonic frequencies help prevent them from getting accustomed to the sound.

How long does it take to see results after installing Defentra?

Most users see results within a few days. Severe infestations may take 1-2 weeks as the device makes the environment consistently uncomfortable for rodents.

What is the coverage area of the device within the engine bay?

The Defentra device is designed to cover a standard car engine bay effectively. The ultrasonic sound waves will reflect off hard surfaces within the engine compartment, helping to saturate the area.

Will the ultrasonic sound pass through solid parts of the engine?

Ultrasonic sound behaves like other sound waves – it travels through open air and reflects off hard surfaces thus securing your engine bay.

Is the Defentra device easy to install? Can I do it myself?

Absolutely! The Defentra repellent is designed for easy DIY installation. It typically involves a simple two-wire connection directly to your car's 12V battery terminals. Clear instructions are provided in the section above.

How do I know if the device is working?

The Defentra device typically has LED indicator lights (both on the main unit and potentially the flashing deterrent lights) that show it is powered on and operational.

Can I use the Defentra repellent in any type of car (e.g., petrol, diesel, EV, CNG)?

Yes, the Defentra device connects to a standard 12V car battery, making it compatible with most petrol, diesel, and CNG cars. For Electric Vehicles (EVs), please consult your vehicle's manual or a qualified technician regarding connecting accessories to the 12V auxiliary battery system if unsure.

Is the ultrasonic sound harmful to humans or common pets like dogs and cats?

The ultrasonic frequencies are generally above human and pet hearing ranges, making it safe and non-intrusive when the hood is closed.

Does the Defentra ultrasonic rat repellent remain active while the vehicle is running?

The Defentra device features a smart detection system that automatically enters standby mode after the car has been running for a period of time.

Will the Defentra device drain my car battery significantly?

It's designed with low power consumption technology and a normally used healthy battery will typically have no problem. Please note that battery discharge due to other components connected to your car battery, such as dashcams, internal security systems, or connected car technology, is not accounted for.

Is the device safe for my car's other electronics or the Engine Control Unit (ECU)?

Is the device heat-resistant for the engine bay environment?

Yes, Defentra is built with a durable, heat-resistant casing designed to withstand the typical high temperatures found under a car's hood in Indian conditions.

Is this a humane way to deal with rats? Does it kill them?

Defentra is a humane solution. It does not kill or trap rodents. It creates an uncomfortable environment that encourages them to leave the area and seek shelter elsewhere.

What should I do if I already have a rat infestation or nesting material in my car?

Before installing Defentra, it's highly recommended to thoroughly clean your engine bay to remove any existing rats, nests, droppings, or food remnants. This removes existing attractions and allows the device to work more effectively as a deterrent.
