If you have seen crows digging up your lawn, you may have wondered why. In this article, we look at why they do this and how to stop them from destroying your lawn.
Crows feed on the grubs on your lawn. The most effective method to stop crows from digging up your lawn is to reduce the number of grubs. Beneficial nematodes will kill ants, fleas, moths, beetles, flies, weevils, and other pests that raccoons feed on. Crows want an easy meal, so make it difficult for them.
Why Do Crows Dig Up My Lawn?
Crows can destroy your lawn. The main reason why they invade your yard is in search of food.
They are likely to dig in your lawn, looking for insects to eat. They usually target larval insects, and they can overturn large yard sections when feeding.
Other animals that may also dig holes in your lawn include raccoons and squirrels. Raccoons will dig holes in your grass searching for food, while squirrels will dig up your lawn to bury food. The ultrasonic animal repellent works well on all of these animals.
Some of the most common grubs symptoms in your lawn will be drying grass, especially two to three inches in diameter, and appearances of brown spots on the lawn.
The main reason your lawn is being dug up is that there are plenty of grubs. These are the larvae stage of a beetle that serves as a rich source of proteins for crows and many other animals.
The grubs have brown heads and white or grey bodies. They are always an attraction to crows, which can end up causing a lot of damage to your lawn.
They are likely to destroy grass around these areas, so you have to do something to stop the crows from coming around your home.
Most animals that dig up your lawn, including crows, will be looking for worms, insects, and grubs. If animals are digging up your yard, you most likely have a grub problem.
How To Stop Crows Digging Up Your Lawn
Crows and other birds ripping up your lawn are trying to find food. They feed on the larvae of chafer beetles. To stop crows from digging up your property, you need to remove the food source.
Removing the grubs is essential, so I recommend grub killer. Ultrasonic bird repellers, motion-activated sprinklers, bird netting, and decoys are excellent ways of stopping crows from digging up your lawn.
Crows are digging up your lawn for food. Grubs are an easy, effective food source for them, and you must limit how many are on your lawn. The number one way to reduce crows digging up your yard is to buy a good grub killer. I have started using Lawnbox grubout. It lasts all season with one application and is 100% organic to give you a healthy lawn.
Use the grub killer in the warmer summer and fall months for the best coverage. Grub killer only works on young larvae, so you must use it after the new eggs have hatched. I don’t know of any nematodes that can kill larvae in the colder temperatures, even in Spring.
I usually treat my lawn in August or September and have had great success in keeping crows away for the last few years.
Ultrasonic Bird Repeller
I use a solar-powered flashing light and ultrasonic animal repeller in my garden. They are humane, use no chemicals, and the one I use is waterproof with a range of up to 20 feet. I recommend this solar animal repeller, as it works well.

You can consider using a motion-activated water sprinkler to act as a deterrent to scare them away. Crows and other animals are afraid of the sudden movement and spray of the water. I haven’t used one of these myself, but my friend loves his. You can find it on Amazon here.
Newly seeded lawns are a good food source for many types of birds. In these cases, I would recommend bird netting. The netting can be pulled tight across the lawn so that it doesn’t catch the birds. However, it will put them off and preserve your lawn.
Many types of decoys can be used to scare away birds. If you are using a decoy such as an owl or other bird of prey, I would recommend moving them around every couple of weeks so that the local birds don’t get used to them. This is also an excellent hint for scarecrows as well.
However, the best decoy I have found is kites. This peregrine falcon is scary enough that it will keep most birds away. Again, I would move it every couple of weeks, but this is an excellent deterrent if you don’t mind having a kite above your garden.
Crows of North America
There are five species of crows in North America, and they can be found almost everywhere. They are large black birds that measure 15.8-20.9 inches (40-53 cm) long and weigh between 11-21oz (300-600g).
Crows are incredibly intelligent, with many scientists now believing that they are as intelligent as chimpanzees. They are opportunistic feeders and eat almost anything, including carrion and human garbage. However, their favorite foods are grubs, which is why they are digging up your lawn.
You can find crows around suburban and urban areas. This is the reason why people regard them as pests. They can cause a lot of harm to gardens as they eat plants and dig in the lawn for insects.
How To Stop Crows From Digging Your Lawn?
As we have already stated, crows can cause severe damage to your lawn as they search for food. If you are sure crows are causing the damage, it is best to stop them. One of the best and the most effective ways of keeping crows from damaging your lawn is to take away the underlying cause.
By realizing they are after food growing inside the lawn and the soil, you can remove the cause. Reduce the number of grubs using Bonide’s insect and grub control. Once the grubs have been removed, you also need to take other actions to ensure crows will not return.
Removing other food sources such as pet food left outside will stop crows from returning, and purchasing a crow-proof feeder may also help.
Which Animal Is Digging?
The first way to determine the animals is to observe the type of holes. Moles will create tunnels and mounds, but crows will flip over whole sections of turf. Crows are looking for food, while moles are looking for food and shelter. Crows can destroy your lawn quickly, especially if there are enough of them.
Many animals can cause the same problem. However, if you suspect that crows are responsible, you have to do something about them. Many gardeners will have an issue with these animals unless something is done to reduce the number of grubs.
How Many Grubs Are Too Many?
A healthy lawn always has a certain number of grubs. A yard can host up to 5 grubs in every square foot. For example, a lawn of 5,000 square feet can be home to up to 25,000 grubs.
It would be difficult to kill all the grubs, and they do so much good for your garden and their natural habitat that you probably shouldn’t.
However, you can take some measures that will minimize the numbers significantly. Experts advise that killing all the grubs is very difficult, even if you use harsh chemicals.
The best action to minimize bugs growing is to use a natural suppression treatment to minimize food for crows. One of the best controls is the use of organic grub control.
There are no guarantees that you will be able to stop crows from landing in your garden completely using any of the above methods. However, a combination of the above techniques will minimize the damage to your garden, and the number of crows invading your property reduced significantly.
