Grub Killers FAQ
How do you get rid of grubs fast?
The minute you notice signs of grub infestation in your lawn, you need to think of how to get rid of it. For this, you need to know the symptoms of drug infestation.
Brown spots or patches will start to appear in your lovely green lawn. The grass itself will look dull and dead-looking instead of green, fresh, and thriving.
You will also begin to notice moles, raccoons, birds, and beetles on your lawn. Once you ascertain that your lawn is infested with grubs, you should determine the infestation level.
The general rule of thumb is that if there are less than five grubs per square foot, it is terrific as long as your lawn is healthy in other aspects.
If there are more, you have no other option but to use grub control products to get rid of them.
You can either use grub killer or Nematodes. However, Nematodes (small parasitic worms) will give you detailed results only after three years (yes, it is quite the long-term solution!).
If you want a quicker solution to keep the grubs in check, you should go for grub killers. These products will not only kill grubs but also protect your lawn from grubs throughout the year.
What is the best time to treat for grubs?
Timing plays a crucial role and can affect how effectively the grub killer you use can get rid of grubs, prevent new adults from emerging, and salvage your lawn.
The ideal time to treat for grubs is early fall or late summer. It is because it is during this time that the smaller, young grubs are susceptible to grub killers (or Nematodes, if that is what you are using).
You can make use of the narrow window in early spring before the grubs get bigger, pupate, and become deadly.
But keep in mind that that is a narrower window, and you may find it challenging to get it right.
Treat at the right time, and you will face no issues with grubs for years to come. The result? A gorgeous looking-lawn you put so much effort, maintaining!
Does laundry detergent kill grubs?
Yes, you can get rid of grubs with laundry detergents. To use laundry detergent to kill grubs, mix laundry detergent with water.
You need to mix only as much as the lawn area where you intend to pour it over.
Pour the detergent mixture you just prepared onto your lawn, and you will notice the grubs rising to the surface immediately.
To get them off the yard, you can do two things. Either remove them yourself, or leave them for the birds, animals, and other wildlife to eat.
This method works well, but we don’t recommend it as a first choice.
It is because the active ingredients in laundry detergents may cause damage to the grassroots in your lawn, slowing down growth.
Will grub-damaged lawn grow back?
If your lawn has suffered due to grub infestation, you can still bring life back to it and restore it to its former glory.
Once the damage has occurred, reseeding is an easy and effective treatment to make grub-damaged lawn grow back. The first thing you have to do is get rid of the dead grass affected by grubs.
Now, loosen up ¼ to ½ inch of topsoil. That is where you will plant the grass seeds. You can do this easily by simply scraping back and forth across the surface.
Next, add fertilizers like a bone meal to encourage healthy roots that run deep. Rake it into the soil that you have just loosened.
Sprinkle the seed over the loosened soil so that every square has 5 to 7 grass seeds. You can sprinkle a little topsoil atop the seed. Ensure that the spot is well-moisturized.
You can do this by watering thrice everyday day. Do this till the seeds start sprouting roots. These roots should be long enough to draw their water from the soil.
Water daily after the grass reaches about 2 inches. You need to keep pets away from your lawn and practice proper mowing techniques.
Mowing should be done only after the grass becomes 3 or 4 inches high.
It is all about the timing when it comes to effective grub treatment!
No matter how good the product is, if you don’t follow the instructions properly and apply it within the proper time frame, even the best products will be rendered useless.
Using too early will cause the insecticides to decompose in the soil even before the grub eggs can hatch.
But applying them late is also problematic because it will be harder to get terminated grubs once the damage to the lawn has already been done.
To make things easier for you, we have curated this list of 5 of the best grub worm killers in the market.
When you first start noticing the signs of grub activity, you should drop everything else and start taking care of your lawn.
Apart from causing damage and leaving brown patches of dying grass, they will also attract other wildlife like moles, skunks, raccoons, and a whole lot more!
These will feed on the grubs by pulling your lawn apart.
Moreover, prevention is always better than cure!
So, even before you start to notice signs of ravage to your lawn caused by grub infestation, you can still make use of grub killers just in case. It will prevent the problem in the first place.
