When it comes to taking care of our lawns, there are lots of additives that just make sense. Grass, after all, is a plant, and plants need water, nutrients, and occasionally some form of weed killer and pesticide. When we give our lawn these obvious amendments, it grows green and lush.
Occasionally, however, there are things we add to our lawns that are not so self-explanatory but are crucial for protecting our property.
A common pest treatment may common in the form of liquids like essential oils or vinegar, but sometimes even an everyday cooking spice can be used to improve the health of our turf. One example of a seasoning that can work as a pest treatment and deterrent is the capsaicin in cayenne pepper which can cause eye irritation and nose damage to potentially harmful pests like deer and dogs.
When applying anything to your lawn, you should do your research so let’s find out if the effects of cayenne pepper will kill our grass.
Is Cayenne Pepper Harmful for Turf?
Fortunately, for plants, there are no harmful effects of using peppers in your garden or around your property to repel unwanted pests. The active ingredient that has the spicy aspect of peppers (capsicum) is undetectable to other plants since it was developed to help peppers not get eaten by animals and not to compete against other garden plants.
While gingerly sprinkling hot peppers with strong scents around your yard will not harm the grass, dumping big piles of black pepper or even a handful of parsley on a patch of lawn looks tacky and may be undesirable for worms and other microbes.
The capsaicin in cayenne pepper may not hurt grass or garden plants but make sure to use gloves when applying fresh capsicum or you may transfer the oil to your eyes and other sensitive areas. It can also be a severe irritant and have adverse effects if too much is applied or it is administered directly to an animal. Pet owners should be especially careful they don’t expose pets while trying make to bug sprays or other pest repellents.
What Does Cayenne Do to Lawns?
Cayenne and other hot pepper seeds, with their spicy flavors, have very little effect on the grass on your lawn. Even pepper with water, when absorbed by the leaves and roots of plants, will not show any signs of distress. The scent of cayenne pepper is only irritating to animals and will not cause your turf to develop spice allergies.
A very highly concentrated solution of cayenne pepper can affect worms as well as microorganisms and will cause severe irritation to any creatures it contacts. Limit applications to areas with fewer composting organisms and if possible direct sprays at fences and other inanimate objects. Always use the correct dilution rate to avoid harming animals within your property lines.
Will Trees and Plants be Affected by Cayenne Pepper?
Plants and trees will not be harmed by pepper, no matter how it is applied. There are no receptors in plants that are vulnerable to the fiery nature of peppers plants. Tossing pepper seeds and fresh peppers, and even dry powder around trees will deter pests but only end up being more plant food once it dissolves into the soil.
Plants that grow in containers may be affected if too much is added, which throws off the balance of microorganisms. If you are trying to use cayenne to ward off pests coming after your potted plants, you may want to consider other repellents or apply it only on occasion when pest attacks are likely. In this way, you can ensure cayenne has no negative effects on your trees and plants.
Cayenne for Pest Control
Pests can do a lot of damage in a short amount of time, so having a reliable repellent like cayenne pepper can be a huge help. Dog poo on the shoe or any other critter excrement is annoying and can be reduced with cayenne spray around your property lines. Below are many of the animals that can be repelled by cayenne powder and spray.
|Pest||Amount of Cayenne||Application Method|
|Dogs||1 teaspoon of cayenne to 8 oz of water||Spray around the perimeter of the lawn and gingerly where dogs have been seen urinating|
|Cats||Small amounts in a spray bottle with water||Squirt on fences and places cats walk and travel along or where they go poop|
|Squirrels||Small amount of powder or spray||Apply near bird feeders, garden beds, and trunks of trees|
|Bugs and Insects||Small amount of powder or spray||Apply to areas of the lawn that have infestations like ant hills and bugs nests|
|Birds||No Effect||No Effect|
Cayenne pepper is effective against mammals that enter your lawn and try to mess up your grass. While you are unlikely to employ pepper on your own pets, there are plenty of critters that are eager to get inside your lawn for various nefarious activities. Fortunately, a very small amount of powder, either sprinkled or made into a spray, is enough to irritate and repel rodents and other mammals who are up to no good.
Lots of bugs make their way into yards, and most aren’t that pleasant. Hot pepper can damage the exoskeleton of many insects and will stop bugs from spreading into your lawn. Generally, direct contact with either powder or a cayenne solution is needed to harm the pests. If the bugs are extra sensitive, just the presence of the compounds may be enough to repel some insects like flies and mosquitoes.
Birds are completely unaffected by peppers as they have a different sense of smell than mammals. Birds eating pepper seeds will not experience the heat or discomfort we feel when munching on hot peppers. This is awesome when you realize you can sprinkle cayenne around bird feeders and bird baths to prevent squirrels and other rodents from showing up. This is a simple solution for many seed thieves.

Pouring a large amount of cayenne on your lawn with the intent of an animal coming into contact with it can lead to damage to the animals. Sniffing too much can harm a dog’s sensitive nasal passage, so only use a tiny amount in solutions and never the powder where a canine might accidentally sniff it.
Only use a few tablespoons diluted in a gallon of water or sprinkled liberally over the whole yard but do not apply it concentrated to any one area. Below are the best ways to apply cayenne pepper to your grass.
A simple way to keep animals from peeing or pooping on your lawn, this repellent is cheap and effective. Cayenne pepper is proven to irritate cats and dogs that are common guests in suburban lawns. Generally, not much of an issue until those pets start to dig up or damage your lawn. Then having a natural repellent can come in handy.
Rodents and deer may be attracted to your garden, trying to grab a quick bite to eat. Applying powder or spray around your garden fences and entry points should not harm them as they run away from the scent. Never throw powder or spray a mix directly at animals as you could harm them; instead, use it as a repellent and spray where you know the pests will be eventually.
Cayenne can also help to prevent digging and burrowing animals that have shown up on your lawn. You can place pepper inside and around the mole and gopher holes in an attempt to scare them off. Too much in the holes may harm worms and other soil microbes so just use enough to encourage these pests to move on.
Kill and Repel Insects
Cayenne is an irritant for many types of grubs and small insects, and enough of it directly on them can possibly kill them. Since there are other more effective insecticides, cayenne is generally used as a repellent instead. Pepper can really help keep down populations of pests like mosquitos and flies that like to land on the lawn but do not stay long enough to pick up some toxins in traditional pesticides.
This method of repellent may work better at keeping them from nesting. Concentrated direct applications can kill other insects like aphids and chinches.
Birds are not affected by cayenne, so they will gladly feast on seeds that have been mixed with it. This is a good solution for keeping squirrels out of bird feeders and may bring more birds to your lawn. Sometimes applying cayenne will encourage insects to move on, and birds may see this as a feast.
The spicy cayenne pepper will not kill grass, but it can keep your yard pest free and make your birds even happier.
