Do Squirrels Eat Cactus

Squirrels do eat cactus, but not in the way you might think.
 
While squirrels don’t typically munch on the spiny pads of most cacti, they absolutely will eat cactus fruit, cactus flowers, and even the tender inner flesh of certain cactus species.
 
If you’ve ever spotted a squirrel nibbling at your prickly pear or saguaro, you’re not imagining things, these clever critters have figured out how to get past the spines.
 
In this post, we’ll dig into why squirrels eat cactus, which parts they target, and how to protect your plants if you’d rather keep them squirrel-free.
 
Let’s explore the surprising relationship between squirrels and cactus.
 

Why Squirrels Eat Cactus

Squirrels eat cactus for a few practical reasons, and it’s rarely about the spiny green pads themselves.
 
These rodents are opportunistic eaters, so when food is scarce or when a cactus offers something tasty, they’ll go for it.
 
The main reason squirrels eat cactus comes down to hydration and nutrition, especially in dry desert environments where water is hard to find.
 
Cactus stores water in its flesh, and that moisture becomes a lifeline for squirrels during hot, dry months.
 
Beyond water, cactus fruit and flowers are packed with sugars, antioxidants, and other nutrients that squirrels need for energy.
 
Here’s a closer look at the specific reasons why squirrels eat cactus.
 

1. Cactus Fruit Is a Sweet Treat

The most common reason squirrels eat cactus is for the fruit, like the bright red or purple prickly pear fruits.
 
These fruits are juicy, sweet, and full of seeds, making them an irresistible snack for squirrels.
 
Squirrels will carefully pluck the fruit from the cactus, often rolling it on the ground to rub off the tiny spines called glochids.
 
Once the glochids are gone, they crack open the fruit and eat the fleshy inside along with the seeds.
 
This is why you’ll often see half-eaten cactus fruit scattered around your yard, a telltale sign that squirrels eat cactus in your area.
 

2. Cactus Flowers Provide a Quick Energy Boost

Squirrels eat cactus flowers almost as often as they eat the fruit.
 
Cactus blooms are tender, soft, and loaded with nectar, which makes them easy for squirrels to chew without dealing with tough spines.
 
The flowers are also rich in carbohydrates, giving squirrels a quick burst of energy during their busy foraging days.
 
In spring, when cactus flowers are at their peak, squirrels will climb all over the cactus to reach these delicate blooms.
 
So if your cactus never seems to flower fully, a squirrel might be the culprit.
 

3. The Inner Flesh Offers Hydration

When water is scarce, squirrels eat cactus for the moisture stored inside the thick pads.
 
Certain cactus species, like the prickly pear, have softer, less spiny pads that squirrels can gnaw into.
 
A squirrel will use its sharp teeth to scrape away the outer skin and spines, then chew into the watery interior.
 
This behavior is more common during droughts or in desert regions where standing water is rare.
 
It’s not their first choice since it takes effort, but when survival is on the line, squirrels eat cactus pads for that life-giving liquid.
 

Which Cactus Do Squirrels Prefer?

Not all cactus are created equal in the eyes of a squirrel.
 
Squirrels are more likely to target cactus species with edible fruit, softer flesh, or fewer dangerous spines.
 
Prickly pear cactus tops the list because it offers both sweet fruit and relatively chewable pads.
 
Saguaro cactus is also popular for its fruit, which ripens in late summer and attracts squirrels from miles around.
 
Barrel cactus is another favorite, as its fruit sits on top and is easy to access without climbing too high.
 
However, squirrels usually avoid heavily spined cactus like cholla or those with dense, needle-like spines that are tough to navigate.
 
If a cactus has both fruit and thin spines, you can bet squirrels eat cactus from it often.
 

How to Keep Squirrels From Eating Your Cactus

If you love your cactus and want to keep squirrels from destroying it, don’t worry, there are several effective strategies.
 
The key is making your cactus less accessible or less appealing to these persistent rodents.
 
Here’s how to protect your plants from squirrels who want to eat cactus.
 

1. Use a Physical Barrier

The simplest way to stop squirrels is to block their access.
 
You can wrap the base of your cactus with chicken wire or hardware cloth, leaving enough room for the plant to grow.
 
For potted cactus, move them to a high shelf or hang them from a hook that squirrels can’t reach.
 
You can also cover the cactus with a mesh netting during peak fruiting season.
 
This keeps squirrels from eating cactus fruit while still allowing sunlight and rain to reach the plant.
 

2. Apply a Natural Repellent

Squirrels have a strong sense of smell, and certain scents drive them away.
 
Sprinkling cayenne pepper, chili flakes, or garlic powder around your cactus can deter squirrels from getting too close.
 
You can also mix a few drops of peppermint oil with water and spray it on and around the cactus.
 
Reapply these repellents after rain or every few days, as the scent fades quickly.
 
This doesn’t harm the squirrels, it just makes them think twice before they try to eat cactus again.
 

3. Provide an Alternative Food Source

Sometimes the best way to stop squirrels from eating cactus is to give them something better to chew on.
 
Set up a squirrel feeder with sunflower seeds, corn, or nuts at the edge of your yard.
 
If squirrels have an easy, tasty meal available, they’ll likely leave your cactus alone.
 
Make sure to place the feeder far from your cactus so the squirrels don’t associate the two areas.
 
This is a friendly, humane way to coexist with squirrels while protecting your plants.
 

4. Prune Lower Branches

Squirrels often climb cactus from the ground or from lower branches.
 
By pruning the lower pads or branches of your cactus, you make it much harder for squirrels to climb up.
 
This is especially useful for tall cactus like saguaro or prickly pear that have low-hanging arms.
 
Keep the area around the cactus clear of debris or rocks that squirrels could use as stepping stones.
 
With fewer footholds, squirrels will find it tough to reach the fruit or flowers they want to eat cactus parts.
 

So, Do Squirrels Eat Cactus?

Squirrels eat cactus, yes, but mainly the fruit, flowers, and sometimes the inner flesh for hydration.
 
They don’t go after the spiny parts unless they’re desperate for water in harsh conditions.
 
Knowing this, you can take simple steps to protect your cactus while still letting squirrels thrive in your yard.
 
Whether you choose barriers, repellents, or alternative food sources, you can keep your cactus safe and your furry visitors happy.
 
So next time you see a squirrel eyeing your cactus, you’ll know exactly what it’s after and how to handle it.
