Tips For Killing Grubs In Your Lawn In Central & Southern Md
Lawn grubs are not only gross, they are also sneaky.Why? Theres no way you can really tell when they attack your lawn because they do their dirty work underground where you cant see them. In fact, your lawn can look just fine on the surface, but grubs are eating away at the lawn roots. And this cuts off the pathway of vital water or nutrients your lawn needs. Pretty mean, right? Since grubs can devastate your lawn in Central and Southern MD, lets get to know these nasty pests and also review a few tips for killing grubs.
Is Dish Soap Effective For Grub Control
It is a given, that dish soap can kill grubs in your lawn or garden, but how effective is it?
Flushing white grubs from underneath the lawn using dish soap is not possible. The best method you can use to check if there are grubs is to dig up a square foot of the lawn a couple of inches deep and inspecting if there are grubs damaging the roots.
I have tested the effectiveness of using detergents and insecticidal soaps to get rid of grubs in infested lawns and while it works, there are quite some limitations to it.
In early spring when white grub worms start to damage the lawn, youll notice brown patches and spots in your lawn. If the damage is small and limited, you can control the grubs using dawn dish soap.
However, for extensive damage over large areas of the lawn, it is very difficult to control grubs because youre spraying on top of the lawn while grub worms continue to cause damage to the roots.
For you to have any success, you may need to pour large amounts of soapy water on your lawn to smother grubs.
I found this to be a practical solution for small areas of infestation. Large yards will require a lot of this application of dawn dish soap to kill grubs effectively.
Japanese beetles, in their adult stage, can be killed in the lawn using dish soap. The soap dissolves their exoskeleton and interferes with their cell membranes. The soapy cover suffocates them to death.
Do I Need To Treat For Grubs
If you have a very high concentration of grubs 10 or more grubs per square foot treatment may be necessary to maintain healthy grass. However, if you have a lower count of grubs, yet arent seeing good results in your lawn, thats a clue that you should revisit your lawn care practices more broadly.
Some of the best practices we recommend are:
- Testing your soil every 2-3 years, and following the fertilizer and amendment recommendations.
- Keeping grass mowed high at least 2, and ideally 3 or more which means that your grass will have a deeper, healthier root system that can tolerate more sub-surface insect feeding.

How To Tell If Your Lawn Has Grubs
As your lawn greens up in the Spring, look for brown patches that never seem to get healthy. If you have a well watered lawn, these can signal the presence of grubs with damage having been done the previous Fall. To confirm your suspicion, lift up a piece of the turf. If it easily rolls up or you see no roots below the soil level, grubs have been here. Also, have you noticed your lawn has become a feeding ground for neighborhood critters? Skunks, Birds, Racoons and Armadillos all love grubs and will tear up your lawn to get them .
Killing Grubs Starts By Knowing The Enemy
Lawn grubs are pretty gross, we know.
Grubs are technically the larvae of bugs like Japanese Beetles, European Chafers, Southern Masked Chafers, and June Beetles. They are white and C-shaped with soft, squishy bodies and legs right beneath their heads. And throughout their life cycles, they can actually damage your plants above and below ground.

How To Kill Active Grubs In Your Lawn
If you have active grubs in your lawn and seem to grow and invade your turf, it is time to take more serious precautions. Here is how to get rid of active grubs for good:
Grub control products that contain carbaryl, imidacloprid, and bifenthrin are effective at destroying active grubs in an established lawn. There are also granular and liquid grub killers on the market.
When using granular pesticides, it is best to apply them using your garden spreader. Dont forget to water to get the product down into the soil and kill the active grubs. When using a liquid pesticide, make sure to mix it with water. Spray the affected areas carefully .
When applying pesticides, it is essential to select the best and most effective product.
Another way to kill active grubs in your lawn is by applying nematodes. Beneficial nematodes are small worms that move under the turf, deep in the soil. They kill the grubs by releasing pathogens that attack them and kill them quickly.
When choosing nematodes, make sure to pick ones that work effectively against grubs. Mix them with water in your regular garden sprayer. Water your lawn accordingly to keep it moist at all types and always spray the nematodes in the evening.

But what are the most effective options for sustainable-minded lawn owners?
Preventive methods top Shetlars list for fighting grubs nonchemically. I emphasize a lot especially to lawn care and sport field managers to keep the thatch down to a minimum, Shetlar said. His key to this: fertilizing ones lawn with nitrogen only once per year, and doing it very strategically and judiciously, to quote Shetlar, usually in late October, early November.
He also mentions research from a University of Kentucky entomologist suggesting you should choose one species of turfgrass over another.
Professor Daniel. A. Potter has conclusively shown that the tall are much more tolerant of grub populations, said Shetlar, who then added, Where Kentucky bluegrass and perennial ryegrass will be damaged with eight to 10 grubs per square foot, the tall fescues usually require somewhere around 12 to 14 grubs per square foot before showing damage.
What about those common organic recommendations for killing lawn grubs online, such as milky spore disease or beneficial nematodes? The commercial milky spore disease is only for Japanese beetles, Shetlar warned. Even then, milky spore disease is a weak pathogen that results in 20% to 25% infection at best.
As for beneficial nematodes, Shetlar said, Theres a very steep learning curve to using the insect parasitic nematodes. They can only be effective when used curatively, and even then, only on small affected areas.
Garlic And Chili Peppers
Some beetles hate the smell of garlic, and so do some grubs. So make a solution of garlic in water and spray all over your lawn or garden to deter them.
If you add some mineral oil and liquid soap in this homemade pest spray, it will also kill larvae. Add some chili peppers, and you have an irritating and efficient deterrent against grubs and beetles.

Controlling Grubs In The Lawn
There are several easy-to-spot signs that you may have grubs in your lawn:
- Raccoons, skunks, or moles are digging up your yard. These animals all love to dine on large, mature grubs.
- You can pull back the dead patches on your lawn like pieces of loose carpet. This happens because grubs eat the roots holding the turf firmly in place on the soil.
- Before the dead patches even appear, your lawn feels spongy when stepped on, as it it were freshly laid sod.
To check if you have a grub problem, peel back a square foot of green turf in several areas of your lawn. If you see 6 or more grubs in each area, it may be time for action.
Beetles, like Japanese and chafer beetles, emerge in early summer, feed on plants in the garden, and lay their eggs in the soil in the lawn. Later in the summer, the grubs hatch and immediately begin to feed. They will continue to eat and grow until mid-fall, when they move deeper in the soil so they can survive through the winter. When the soil warms up again in the spring, the large, mature grubs move back into the upper soil levels, where they transform into adult beetles that emerge in early summer and start the whole process over again.
Preventive: Insecticide That Will Prevent Grub Damage Next Fall And The 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 had confirmed grub damage the previous fall or spring 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 chafer and Japanese beetle in the area, it is necessary to treat every year or your lawn will be damaged by grubs. This is not true.
Preventive products are the most effective.

Chafer Grub Lawn Damage
Chafer grubs are the larval forms of Chafer Beetle. A severe infestation of these larvae causes brown patches in the lawn.
Chafer grubs devour the roots of the grass and could go unnoticed for months. They are only outed by critters when they dig out the lawn.
The aforementioned methods work well to eliminate chafer grubs but the most efficient way to get rid of them is by using Provado.
Provado Lawn Grub killer
Provado lawn grub killer can eliminate Chafer grubs and Leatherjacket larvae efficiently. Imidacloprid thats present in the insecticide is the miracle behind such efficiency.
Recommended Practices As You Use Pesticides
- If you decide to use a pesticide to kill the grubs, it will probably be toxic to good insects like bees and other pollinators as well.
- To protect them from harm, mow your lawn before you apply the chemical to get rid of flowers that may attract them.
- Water your lawn after you apply the pesticide to avoid burning your plants and to enable the soil to absorb it.
- Dont apply too much pesticides as it will run off your lawn and into the environment. Use only the recommended usage on the back of the bottle.
