Squirrels may be cute but they are pests and are known to feed on farm produce such as wheat, corn, soybeans, fruits and oats.  They are a hazard to farmers. Their speed makes it difficult to get rid of them and so it becomes necessary to make use of squirrel repellants.

There are basically two major types of squirrel repellents – Ultrasonic and Chemical repellents. Both of these are effective. There are, however, a few differences between them.

Difference Between Ultrasonic and Chemical Repellents

Any sound wave over 20kHz is ultrasonic. This sound is inaudible to humans and audible to dogs and most animals, including squirrels. Ultrasonic repellents emit different pitches of sounds that frighten and irritate squirrels, thus repelling them.

Chemical repellents, on the other hand, include those using natural ingredients such as fox’s urine. They work because these repellents contain ingredients disliked by squirrels.

Since it is not easy to find the best product, the best squirrel repellents have been given here to help the reader.

Tips to Use Squirrel Repellents

Preventive measures such as throwing out garbage, keeping trash sealed, keeping food source away from squirrels, installing metallic or other protective structures around the property should be taken to make it difficult for the squirrels to enter.

People with pets should let out their cats and dogs as they the best deterrents. Squirrels are afraid of these big animals and keep away from them

Eliminate the source of water as squirrels will appear wherever there is water. Like every other being, squirrels need to keep hydrated and are naturally attracted towards places with a regular source of water.

Clear out places, especially the attic, where squirrels tend to build nests.

Use a rotary sprinkler that is motion activated to scare away the critters.

Squirrels hate flowers such as mint, lily of the valley, geraniums, daffordils and others. Plant such flowers in the garden. Other plants that can be planted are garlic, onion, herbs, scallions and leek, the smell of which drives squirrels away.

Squirrels are cute but they are pests nonetheless, causing damage to property, food and making nests out of wires inside the house. While all these products are good to use, it is always best to take preventive measures as given in the tips and tricks section. Cutting out the source of food and water is one of the best ways to keep out squirrels. The pests will not go where there is no food and water. Also, it is necessary to cut out entry into the house. Seal cracks to prevent them from entering. People with bird-feeders in the garden have these regular visitors. They need to use squirrel proof products to ensure that only birds visit them.

Remember that these critters are small, fast and jumpy. They have sharp teeth and jaws but they prefer to run rather than fight. Take advantage of this nature and use products or pets to get squirrels to run away. As mentioned before, dogs and cats are big squirrel deterrents and should be let out as much as possible. In fact, there should be no schedule in their outings.

All these together will help keep squirrels away without actually causing them any harm.
