1Identify Your Nuisance Animal

It's important to know what type of animal is causing damage in your yard so you can effecticely repel them using the best tactics and repelling products for that particular critter. Take a look at the damage that is occuring - for example:

Deer damage occurs between 3-6 feet above ground level. Deer prefer the tenderest parts of plants including buds, young stems and leaves.

Squirrels and chipmunks steal bird seed. Squirrels chew through materials like siding and woods to access shelter, while chipmunks dig burrows and can damage building foundations.

Groundhogs chew anything wooden in order to sharpen their teeth. They also burrow, leaving large holes and dirt mounds.

Raccoons raid trash cans and tip over flower pots.

Rabbit damage occurs up to 3 feet from the ground, in the form of clean, angled cuts on the end of stems and leaves.

Cats and dogs urinate on your lawn, killing grass.

2Know What You Want to Protect

Whether you want to defend your entire yard, a small vegetable garden, or one bird feeder, it's important to identify exactly what area or surface you want to target, so can determine what kinds of repellents to use.


3Select the Best Animal Repellent(s)

Once you've identified your target animal and determined the areas you want to protect, use the information below to choose the best animal repellent for you. Note, different repellents serve different purposes, so the more solutions you employ, the better your chances at keeping animals away long-term.

Liquid Repellents

Best For: Preventing animals from browsing and/or damaging targeted surfaces. Spray directly onto surfaces such as:

  • flowers
  • shrubs
  • mulch
  • roofing
  • ornamentals
  • seedlings
  • woodpiles
  • gutters
  • trees
  • bulbs
  • bird feedes
  • trash cans/bags

TIP: Most liquid repellents are for outdoor use only, and must be sprayed in temperatures above 40° F.


Granular Repellents

Best For: Keeping animals out of protected areas. Sprinkling granules creates a repellent barrier around areas including:

  • gardens
  • entryways
  • garages
  • burrows
  • flowerbeds
  • houses
  • attics
  • gutters
  • pathways
  • barns
  • crawl spaces
  • trash cans/bags

TIPS: Spread granules on grass to prevent animals from digging. Granular repellents can be used in any weather and some may even be used indoors. For more information about choosing between repellent types, read Liquid vs Granular Repellents.


Covered Repelling Stations

Best For: Guarding plants and edible crops - the repellent is contained and protected in a durable casing, so it is completely weatherproof and does not contact your edible crops. Apply them in various ways, including:

  • Staked throughout vegetable gardens
  • Positioned around yard perimeters
  • Placed in planters or flower pots
  • Hung from trees or fences

TIPS: Covered repelling stations deter animals with scent and therefore work best in warm weather as heat will permeate through the station and carry the odor better than in cold weather.


Electronic Repellents

Best For: Effectively repels animals without chemicals. Electronics are also very convenient as they run 24/7 without intervention. Types of electronic animal repellents include:

  • Motion-Activated Sprinkler Repellents: These highly effective scare devices frighten away a large variety of animals with starling bursts of motion, water and sound.
  • Ultrasonic Rodent Repellents: These devices are mainly targeted to rodent and repel using piercing, high-pitched sounds only small animals can hear.
  • Wireless Fence Posts: Targeted specifically to deer, these devices lure the animal with an acorn scent to electrodes that deliver a conditioning static shock.

4Apply as Directed

The effectiveness of an animal repellent is contingent upon proper application. It is critical that the user follows the directions for use on the package. Some important steps include:

Reapply liquid and granular repellents periodically as directed and after periods of heavy rainfall to maintain repellency.

Shake liquids well before each use to ensure the proper mixing of active ingredients and to prevent clogging the sprayer.

Position motion-activated sprinkler repellents and electornics so that the motion-sensor points in the direction in which animals are approaching.


5Reduce Attractants

Animals are attracted to areas with available food, water, shelter and/or cover. Regularly maintaining your yard can make your home less inviting to animals and increase the effectiveness of your repellents. Some actions you can take include:

  • Cleaning up fallen berries, nuts, birdseed, etc.
  • Harvesting crops as early as possible
  • Replacing bird seed with thistle
  • Removing garbage and securing trash cans
  • Filling in any abandoned animal burrows
  • Mowing grass/pulling weeds/raking leaves
  • Trimming back overgrown plants

Expert Tips

Animal repellents should be applied at the very first signs of animal damage to prevent them from developing destructive habits, which are often difficult to break.

When applying liquid repellents, it’s important to thoroughly spray the repellent onto all parts of the plant you want to protect until the liquid begins to run off.

If you plan on using a high quantity of liquid repellents either for a large property or for multiple uses, try a concentrated repellent. With concentrates, you can mix a small amount with water to get more ready-to-use liquid.

Pateince is key when it comes to repelling animals. Although most liquid and granular repellents are effective immediately, it may take several interactions for the animal to associate the unpleasant irritation with the protection area. In some cases, more repellent may be needed OR it may need to be applied in a different location to influence the interaction that will ultimately repel the animal.

Concentrates are great for protecting bulbs - before planting them, dip the bulbs into a concentrated solution that’s proven to repel your nuisance animal.

Avoid homemade animal repellents; their effectiveness is inconsistent and unproven. Additionally, homemade animal repellents will not have any sticking power so get ready to apply at each and every rainfall.
