– Effects on Grass
Castor oil does not negatively affect grass, so it is safe for use. However, it does not do any benefit either. You spray the grass with this oil and expect it to increase its growth or spread faster than ever.
Unlike most other oil types, castor oil forms a relatively thin layer over the surface of grass blades. Your grass doesn’t look greasy at all, like it has oil poured over it. The grass will feel sticky when you walk over it or touch it with your hands.
Castor oil has a strong smell, many dislikes and do not want to deal with. Even pets, especially dogs, are strongly put off and repelled by this smell.
Castor oil applied on grass will eventually seep into the soil along with regular watering. The fortunate side of this is that castor oil is as harmless to the soil as it is to the grass. You do not have to worry about oil affecting the soil’s nutrient levels or messing with the pH of the soil.
– Repels Skunks
Skunks are a big nuisance that will not leave your lawn alone once they start visiting in search of food. The worst thing about their unwanted visits is the unpleasant smell they leave behind that is extremely hard to eliminate.
They also mess around with your garbage can while destroying grass and vegetation during periodic visits. This smell can harm your lawn, hence using this oil will be beneficial to you.
Keep in mind that these animals love to eat grubs that are part of the lawn’s natural ecosystem and end up digging your entire lawn in search of them.

Then mix in half a pint of liquid dishwashing solution to it. Often, skunks leave behind visible signs about the parts of the lawn most frequently visited by the skunks. You need to spray your castor oil solution to repel skunks away in these spots. If you are unsure about such spots, spraying all over the lawn or the outer perimeter is safe.
You can use any spray bottle with a medium-sized nozzle to carry out this spraying operation. Skunks will keep visiting the lawn for at least two weeks before their habit breaks, so keep reapplying the repellant solution, especially after a proper amount of rainfall.
– Keeps The Moles Away
There is no better natural mole repellant than a homemade DIY castor oil spray. Moles dig holes all over the lawn and damage grass blades. Castor oil messes with their digestive system and repels them, which means they leave without harming them, and you won’t find them dead in the lawn.
You need to make sure that your oil has the best quality and is authentic without artificial additives. You may even go to a certified natural produce seller, and do not worry if you have to pay a little more than cheaper but lower-quality alternatives.
Collect one gallon of fresh water in a bucket and add six ounces of castor oil. Two tablespoons of vegetable oil or dishwashing solution help this mixed solution stay on the lawn longer than it would have otherwise. Keep in mind that this is the most effective castor oil mole-repellant recipe.
One method is to put a bit of this solution in a spray bottle with a nozzle and spray it all over the lawn.
This method is fine, but will take a very long time. Note that an easier approach would be to use a hose sprayer to cover more ground in less time. You can connect the hose to the sprinkle so that the entire lawn gets evenly saturated with the mixed solution.
If you like walking and spending time on your lawn and don’t want all of it saturated with the oily mixture. In that case, you must first observe the spots with the most mole holes and target these spots only.
However, after you have sprayed, you must let the oil soak deep into the soil so that moles hiding underground can be targeted, note that you can lightly water the areas that were sprayed earlier, taking care not to splash this water. Only about an inch of water should suffice in this situation.
– Repelling Pests
There is a reason why all commercial bug repellents contain castor oil granules as their prime ingredient. It can kill the eggs and larvae of all kinds of pests and bugs commonly found in home gardens and lawns.
Just as you spot them this is the proper time that you can mix this oil or its granules with essential oils like rosemary or lemongrass to make pest-repellant solutions at home.
Homemade solutions do not provide instant results like commercial pesticides and need frequent reapplications. On the plus side, they are way safer for plants, humans, pets, and the environment. Using this solution, you can expect to get rid of fleas, ticks, mosquitoes, beetles, grubs, termites, and more.
Even if you do not want to buy expensive essential oils, mix two parts castor oil with one part dishwashing liquid soap. Add two tablespoons of this foamy mixture in one gallon of water and spray weekly on a bug-infested lawn.
Again, taking help from a sprinkler to spray all over the lawn will save you so much time and even energy.
Unlike commercial pesticides, you can let kids play outside on a lawn sprayed with this solution without any concern for their health. Spray every week, and you will see a marked reduction in your lawn’s pest population and a visible improvement in the quality of the grass and plants.

If you own a dog, it can accidentally end up ingesting them and get severely sick. Signs of castor oil toxicity in dogs are drooling, abdominal cramps, and mouth burn. Your canine friend will appear in agony and might suffer from nausea and vomiting.
Immediately take the sick dog to the vet if any of the symptoms mentioned above develop, and you suspect castor oil toxicity. Do not use granules if you own a dog as a preventative measure.
Liquid solutions containing castor oil are much more diluted and unlikely to be licked by dogs in significant enough quantities to be dangerous. This is another reason you must go for a liquid DIY solution if you have pets of different kinds and evens kids at home.
