10 Natural Ways to Get Rid of Grubs in The Garden

Many a home grower and farmer have dealt with the irritation of finding grubs among their plants and crops.

It’s not a pretty sight, seeing little white worms crawling all over the place, eating your precious harvest and destabilizing the structure and stability of your plants.

If you’re reading this article, then it’s a good bet you’re seeking a natural, harmless way to get rid of grubs once and for all, with natural being the keyword here.

Fortunately for you, there are plenty of methods you can use to rid your garden of these little annoyances without harming either your plants or any of the beneficial insects you want to keep.

Many of the mentioned methods are highly effective, but plenty are also somewhat harmful to the insects you want in your garden. Hence, it’s important to make sure you’re getting what’s right for you and your garden.

If you’re still not sure about what to try, read on for tips on how to get rid of grubs naturally.

What are Grubs? 

Grubs are essentially nothing more than tiny, wriggly baby beetles laid by parent beetles into your garden and hatching out as little white worms.

In all life stages, they’re especially harmful to your garden and need to be dealt with as soon as possible.

As grubs, they nibble on the roots of your plants. This leads them later in life to chewing up the leaves of your prized garden, harming the plants and their ability to photosynthesize.

They spread like wildfire and once you’ve got them en masse, they’re tricky to get rid of because of how many of them can appear at one time.

Because of their damaging nature, it’s imperative to get rid of grubs as soon as they’re spotted. If not, you’ll be in for a rough time dealing with them as they mature.

They’re little ticking time bombs of destruction and mayhem for your harvest, so take these little buggers seriously. 

Signs of Grub Infestation 

You’ll see telltale signs of a grub infestation when you notice dead or damaged patches in your lawn. If it feels spongy and soft to the touch and if you see various wildlife digging at your grass, that’s another indication.

If you happen to pull back a section of grass and can count more than five grubs per square foot, you’ve got a fairly significant explosion of grubs this year.

This means your lawn likely wasn’t very healthy, to begin with. A healthy lawn is usually able to withstand such infestations to some degree.

If you notice these signs in your lawn, it means that grubs are most likely present in your garden as well.

Droopy leaves, the sudden death of plants, and the appearance of moles are all signs that your garden is infested with grubs.

It’s best to treat your garden and lawn for grubs before an infestation can happen. It’s usually in the spring or fall when they’ll be most active and feeding. 

Natural Ways to Get Rid of Grubs 

There are many home remedies for grub control. Some are items that can be readily accessed and others are things you can do to limit infestation.

There are also eco-friendly pesticides available. Not all pesticides are harmful to your garden and its crops. In fact, there are several brands that are quite natural and healthy for both you and your harvest.

Many of these can easily be found either at your local gardening store or else online for quick shipment. Any one of these methods is guaranteed to help rid your garden of beetle grubs before they can do any permanent damage.

Just be careful to make sure and read the components of each type very carefully and choose only those that are organic or OMRI listed.

All will do the job precisely as you wanted. However, not all will take care to spare the beneficial organisms who are actually helping your garden at the same time.

Pay close attention to what you’re applying to your garden so you eliminate only the annoying grubs chewing viciously on the roots.

There are plenty of choices to look at. Below are 10 eco-friendly ways for how to get rid of grub worms. 

1. Beneficial Nematodes

These tiny nematodes actively seek out grubs and similar soil-dwelling pests as their favorite treat. What’s more, you can purchase beneficial nematodes for your garden.

You simply soak them in water on the sponge they come in. Put into a sprayer attached to a hose and then give your garden and lawn a good and thorough rinse to release them. 

2. Milky Spore Disease 

This is a naturally occurring pathogen that, once released into your garden, won’t harm you or your plants.

It’s highly effective against grubs, but the problem is that it can take up to three years before it reaches its maximum potential.

It’s best to combine it with other techniques, such as the nematodes for the best effect against the grub enemy. 

3. Birds and Chickens 

Set up bird feeders or a chicken coop. The former may be easier, but with the latter, at least you’ll get eggs out of it.

The birds will peck and forage voraciously against anything they find in the soil, especially beetle grubs.

The only con to this otherwise brilliant plan is that the birds may also go after any beneficial insects you’ll want to keep, so give it some thought first. 

4. Organic Fertilizer 

Using organic fertilizer compared to synthetic stuff has a lower chance of killing helpful organisms, such as the mentioned nematodes.

It may not stop the grubs, but because it allows everything else to keep living. The other organisms stand a better chance of surviving another day to eat the grubs. 

5. Neem Oil 

This is a very popular option for gardeners as a natural and healthy pest control oil.

Mix with water and then spray generously across your garden to prevent grubs from appearing and, most importantly, feeding.

It can be found decently priced online and at some retail gardening shops. 

6. Diatomaceous Earth 

This special powder contains the skeletal remains of diatoms.

It is used to crack holes in the exoskeletons of any insects it comes across, dehydrating them to death.

It’s very effective, but it is also indiscriminate, so use sparingly.  

7. Garlic Spray 

Actually, a lot of insects can’t stand garlic spray, and grubs are no different. For this homemade grub killer, you can look up different solution mixes online for the best treatment.

For a simple solution, puree 4 bulbs into one cup of water and let it sit overnight.

Strain and then spray around your garden to discourage both grubs and whatever else you don’t want skulking about in there. 

8. PyGanic Gardening 

A special organic insecticide that has been widely proven to relieve gardens and lawns of all varieties of annoying pests, grubs included.

PyGanic is safe for most types of crops and works on a wide array of different insects. 

9. Surround WP

Made from specialized Kaolin clay, this stuff forms a protective shield around vegetables and other plants when sprayed on liberally.

Surround WP repels pests and causes severe debilitation in any who try to brave it to eat or lay eggs, such as confusion or irritation. 

10. Limit Irrigation 

White grubs require moisture for a healthy environment to grow successfully.

Therefore, if you limit the amount of water flowing into your garden, you can effectively dry them out.

This will prevent them from moving around easily and eating whatever they come across.

Whatever doesn’t require as much water can be left alone, and you’ll save some money in the process on your water bill. 

Takeaway 

Grubs can be a royal pain in the neck for any gardener or farmer, and there are so many ways of dealing with them that it’s often hard to choose.

Fortunately, with a little research and experimenting, you’re bound to find the perfect natural remedy for keeping these pests out for good.
