Squirrel Repellents

Once you’ve grown tired of squirrels damaging gardens, breaking flower parts, building nests within your attic or being too close to your car, they’ve given enough reason to dislike their presence. When there’s an abundance of squirrels there is an increased risk of rabies for your own pets, as well as disease-carrying fleas. Take notice of any droppings around your garage, scratching, rustling or clicking noises in your attic, which are all signs of a possible infestation.

Rodent infestations don’t always mean resorting to traps, or even poison to kill them. There are many options available that won’t result in dead animals, or toxins in order to deter squirrels. Keeping rodents at bay, while being gentle on the environment, will allow you to breathe easier and healthier.

How to Deter Squirrels?

1. Identify Damage

When you find yourself in need of a squirrel repellent, it’s best to first determine the location of squirrel damage so you may know where to apply repellents.

2. Choose the Best Squirrel Repellent for You

Follow the information below, for each area of damage, in order to decide which repellent fits your needs best. Repellents should be applied as preventative measures, before damage has begun, in areas of high squirrel density and pressure. Often, in many cases, layering multiple repelling solutions will offer the best possible results, when done on a regular basis.

3. Remove Attractants

It’s important to maintain the cleanliness of your yard, by removing potential food sources, to also prevent pests. See, squirrel repellents work best when they aren’t competing with other attractants nearby.

Tips & Life Hacks:

  • The trick of using the repellents is to start applying them as soon as you notice squirrels on your property.
  • Then, use different types of repellents, either interchangeably or one after another, so the squirrels don’t get accustomed to it.
  • Once squirrels make their nests and establish habits in your yard, they are very difficult to control. This is why squirrel repellents should be used as a preventative measure, or at the very first signs of squirrel damage.
  • It’s important to be patient and consistent with your squirrel repelling strategy. Although liquid and granular repellents are effective immediately, their effectiveness relies on a squirrel’s interaction with them. It may take several interactions with the repellent for the squirrel to associate the unpleasant taste and irritation with the protected area.
  • Squirrels do the most damage when they are eating or gnawing on birdseed, plants, siding, wires, etc. The best squirrel repellents tackle these problems head-on by targeting and irritating a squirrel’s taste buds. Look for repellents with capsaicin and other pepper-based ingredients that are proven to deter squirrels in this way.

What Kinds of Repellents Exist for Squirrels?

1. Natural repellents

Natural repellents are those of plant origin. They primarily work by odor or taste aversion. Consider planting peppermint across the perimeter of your garden. Other plants that you can consider planting include any type of narcissus bulb (daffodils, paperwhites, jonquils), geranium, and hyacinth. These plants send a message of toxicity odor to the rodents that might keep them at bay at least for a while.

2. Chemical repellents

These types of products usually contain enemy blood traces, predator urine, feather meal, and other ingredients that can scare rodents away.  The general rule is that squirrels (and other rodents likewise) get scared when feeling or smelling their enemies, or predators.

3. Electronic Ultrasonic Repellents

Electronic repellents emit high-frequency sound waves that are unbearable for rodents. While the effectiveness of such devices has not been confirmed by serious scientific research, many buyers notice that such devices, in fact, help a great deal.

4. Home-made Repellents

May I eat fruits and vegetables treated by such natural spray?
It is not advisable you consume fruits or veggies treated with a repellent, especially if you are allergic to any of its components. That is why we recommend using repellents either by placing them directly underneath the plants or by mounting a barrier around the plants and applying the repellent on there.

Should I reapply natural repellents after rain?
Yes, you should. Even if the manufacturer claims that there is no need to replace/change or add new portions of a repellent, we still recommend you do. Especially after a heavy rain.

Can you recommend squirrel deterrents for bird feeders?
Yes, you can, in fact, use any deterrent that contains pepper. Spray it directly on the feeder to repel annoying squirrels, while pepper is unpleasant for rodents, birds don’t mind it.

You can also try to boost up the repelling results by changing repellents over time, using different types of repellents at once, or using them in combination with squirrel traps.
