If you are one of those homeowners who suffer from the constant attention of rats to your yard, garden, attic, or basement, read our efficient tips to make away with these annoying rodents. We’ll provide you with our rat repellent guide that will help you to determine the most effective repellent and deterrent product for you!

Effective Solutions on How to Repel Messy Rats

If you don’t want crafty rodents to destroy your property or your family’s health you can drive these disease-carrying pests with efficient rat repellents and deterrents.

Here is how to do it:

  1. Identification
    Before repelling, find out where these smart rodents spend most of their time. Identify rats’ signs of activity or damage like – rats’ tooth marks on cabinets, baseboards, grease marks along your walls, chewed wires or biting large holes in the packaging. Note that rats prefer to live quiet in less-frequented places like your closets, attics, and basements.
    Identification rats
  2. Choosing the option
    Now it’s time to choose an effective repellent. There are many ways to go. From ultrasonic repellents to natural rat repellent sprays it’s up to you what to choose.
  3. Attractants
    Don’t let them feed in or around your home. Since food is the rat’s main driving force, it’s essential to remove or protect food sources. Clean your property on a regular basis, store all indoor/outdoor garbage in rodent-proof containers, and clear all fallen seeds, nuts, etc.
  4. Eliminate rats’ access
    Once you’ve driven them away, take steps to ensure rats cannot re-enter. Cover the gaps underneath garage/pet doors, relocate piles of debris or wood, and seal spaces around openings for cable, vents, and water pipes.

Electronic Rat Repellent Ideas and Products

Many homeowners prefer electronic options to repel rats as they are safe and eco-friendly. What’s more, you don’t have to deal with the best rat traps that require the handling of disease-ridden rats or the best rat poison products that cause rats to either die outdoors or retreat into your walls to die and decay.

Ultrasonic rat repellents irritate rats and successfully drive them to another location. Electronic options work by emitting high-frequency sounds only audible to rats and other rodents.

Electronic rat repellents are easy to use. Simply plug the device in an outlet in the place where you have identified rat damage.
If you have rodent pets at home, relocate them away from repellents. Rats will start to relocate after about 7-8 days.
It is recommended to replace the device every two or three years.

Unfortunately, ultrasonic waves can’t travel through walls, so you need to purchase a device for each room. When selecting the device, purchase the one that has a signal strength fitting the size of the room you want to protect.

Let’s focus on excellent electronic rat repellents that work harder to protect your property:

It’s difficult to state the best rat control option. When it comes to electronic rat repellents they are very effective at repelling rats when used alone, and even more efficient when used in combination with other rat repellents. For example, you can try an ultrasound rat repellent alongside some rat spray or granular repellent. Remember the more options you use the better your defense is.

An integrated method that includes eliminating attractants, repelling, and trapping is the best form of successful rat control.
Using multiple rat control options will surely result in the most effective and successful defense.

  1. There is a 14 year old, Monterrey Oak outside my bedroom window which I think roof rats might be climbing to get onto the roof. The branches were pruned back from the walls, but are still above the roof. I hear the thud of some small bodies dropping onto the roof at night and the pitter-patter of little feet. Never hear any gnawing. I was wondering if pepper spray used to keep assailants away could also deter roof rats?

  2. Please provide me with ideas to get rid of rats from my back yard. Do they like oranges as I have several Orange trees? I want to use natural repellents as I have pet dogs. I have purchased electric rat traps.
