Biological predators, like birds, raccoons, moles and more, are an option when it comes to grub control for lawns. You can choose to leave your soil exposed to welcome animals to devour the pests. For example, you can use bird feeders to attract birds to your yard to feast on the grubs. But do keep in mind, animals will dig holes in your lawn, which can cause further damage to your yard.
Lawn Grubs: What Exactly Are These Icky Creatures
Grubs are the larvae of Japanese beetles, June beetles, chafers, and other beetles.These white, C-shaped grubs have soft squishy bodies with legs near their head. They feed on grass roots and organic matter in the soil, causing sections of grass in the lawn to die. It can happen really fast. One day youre looking out at your healthy lawn, two days later its wiped out entire patches will be brown, dry, and wilted. Why didnt you see it coming? Because lawn grubs are super sneaky.

Get Rid Of Grubs For Good
Though grub populations can be an unsightly annoyance, there are several different ways to reduce their numbers while still looking out for your yards health. Make sure to monitor your grass for brown spots and look into lasting, natural solutions for grub infestations!
The best way to get rid of grubs is to use natural methods that will help keep grubs away for good rather than using pesticides and having a recurring problem year after year.
Why Are Grubs Bad
A large grub population can decimate a vegetable garden, flower bed or natural grass lawn, but most serious grub issues that homeowners deal with have to do with their lawns. While a small population is generally not an issue and will not destroy your grass, a population of 10 or more grubs per square foot can cause significant damage.
The damage caused by grubs is largely due to their diet, which consists primarily of grass roots, as well as other organic matter in the soil. As they eat the roots of your grass, they destroy the root system, which means your grass will not get the water and soil nutrients it needs to stay healthy. This will lead to patches of grass that are brown, dead and easy to pull out of the ground.
A significant grub population can also lead to lawn, flowerbed, and garden destruction indirectly as birds, raccoons, and other grub-eating critters tear up your lawn or garden to get to the grubs.

Natural Ways To Get Rid Of Grubs In Garden
Many gardeners have dealt with the irritation of finding grubs in the soil among their plants. These critters are voracious root-eating worms that turn into leaf-eating adult beetles .
Its not a pretty sight, seeing fat white worms crawling around, eating the roots of your crops, and damaging your lawn.
If youre reading this article, then youre likely seeking natural, harmless ways of getting rid of grubs once and for all.
Fortunately for you, there are plenty of methods you can use to rid your garden of grub bugs without harming your plants.
Use Neem Oil Or Azadirachtin
Azadirachtin is a component of neem oil. While many people think neem oil and Azadirachtin are the same things, neem oil contains very little Azadirachtin.
As such, people usually buy concentrated Azadirachtin to use on their lawns. According to one study, Azadirachtin application on Kentucky bluegrass killed Japanese beetles at 5x the products label rate.
Neem oil is another pest control option. Pure neem oil deters the grubs from feeding, growing, and laying eggs. For best results, mix neem oil with water and spray the diluted solution on affected areas.
Cons: Both neem oil and Azadirachtin require regular reapplication despite its efficacy at killing larval Japanese beetles, Azadirachtin wont kill mature beetles or deter them from laying eggs.

Preventive Insecticides That Will Prevent Grub Damage Next Fall And Following Spring
These products are used to prevent future grub problems, not to control the grubs present in the lawn in the spring. They will not work on grubs found in the lawn from the middle of October through the middle of May. However, when applied in June or July they provide excellent protection against the next generation of grubs. So, if you need to apply the preventive insecticide BEFORE the grubs are there, how do you know if you need to use an insecticide or not? If you confirmed grub damage the previous fall or spring, meaning you found lots of grubs, then you may want to use a preventive insecticide for one or two years to build a more dense turf that will be tolerant of grubs. If you have treated for several years and you do not see evidence of grubs in your lawn or in the neighbors lawn, it may be time to stop treating. There is an erroneous philosophy being perpetuated that because we have European chafers and Japanese beetles in the area, it is necessary to treat every year or your lawn will be damaged by grubs. This is not true.
In addition, grub control products that contain the active ingredient chlorantraniliprole are safe for bees, even when weed flowers are sprayed. Finally, avoid spray drift or granular spreader drift to flower beds when applying thiamethoxam, imidacloprid, clothianidin or any insecticide for grubs other than chlorantraniliprole
A Summary For Successful Grub Control
- Check the bag or bottle to determine what active ingredient the product contains.
- Do not use products containing ONLY lambda-cyhalothrin, gamma-cyhalothrin, bifenthrin, deltamethrin, cyfluthrin or permethrin for any phase of grub control.
- Do not use preventive compounds such as clothianidin, thiamethoxam or imidacloprid now. Use them in June or July to control grubs that would be damaging turf in the fall. Applying them now will allow some of the chemical to leach through the turf or break down to the point that not enough insecticide will be there in July to control grubs.
- The preventive compound chlorantraniliprole should ideally be applied in April or May to control grubs that would be damaging turf in the fall as it will take longer for the material to move to where the grubs will be feeding in July.
- To kill grubs in the spring or fall, use carbaryl or trichlorfon.
- Always wear rubber gloves and rubber boots when applying insecticides to turfgrass.
- Make sure to irrigate the lawn with at least 0.5 inches of water* and allow the grass to dry before allowing anyone or pets into the treated area. Irrigation is essential for the chemical to be most effective.
- Store insecticide products in a locked cabinet not accessible to children.
- Proper fertilization is important to prevent and allow the lawn to recover from grub damage.
- Mow lawns immediately before applying an insecticide for grubs to remove weed flowers and protect bees.
- Apply in spring or fall to active grubs.

Make A Homemade Grub Killer With Borax
Before you consider making a homemade grub killer using borax, it is important to note that borax contains boron, and too much boron will kill your grass. If you use a borax grub killer repeatedly on your lawn or in flowerbeds or garden beds, the boron will accumulate in the soil and nothing will grow. So, this option should be used sparingly, if at all.
If you choose to use borax, the simplest recipe is to add one tablespoon of borax with warm water in a spray bottle. Then, use the spray bottle to distribute the borax-water solution on areas where you have found grubs. You will need to repeat this treatment until you have eradicated the grub population, so remember the part about boron accumulating in the soil over time before you choose this option.
Other recipes for borax grub killers include mixing onion, peppers or garlic in the warm water with the borax.
