Grub Killer Buyer’s Guide
The spring is here, and it’s time to concentrate on your yard as the ground thaws and the buds start to shoot. Your lawn starts to come back to life after its winter slumber, and green shoots begin to emerge among the born thatch.
In a few weeks, your lawn will be back to its former glory, providing a luscious green landscape to your yard. However, after your grass comes around, you notice brown patches popping up in random places – what’s with that? You don’t own a dog, and you don’t remember spilling any chemicals on the lawn recently.
The reality is that something sinister is going on under the grass. Grubs are the favorite food of moles and voles, and they overwinter under your lawn, coming back to life in the summertime as the ground warms.
After investing so much time and effort into your lawn, it’s tragic to see the effects of grubs gnawing at the roots of your grass. Those unattractive dead patches in the lawn look terrible, and the presence of grubs attracts voles and moles to your yard.
Fortunately, you can protect your lawn using a specially formulated grub killer. These insecticide products kill grubs on contact, ensuring your lawn looks great all year.
In this section, we’ll unpack the different types of grub killers’ products and help you select the formula that’s the right choice for your garden and your budget.
Why are Grubs Bad for My Lawn?
Grubs are the larvae of various insect species. They reside under the lawn’s surface until they transform into a mature insect. Grubs survive by gnawing on the tender grassroots in your lawn. All grass can tolerate some level of grub feeding – it’s part of the natural world. However, some lawns experience severe grub infestations that damage the grass.
If you start to notice yellow patches appearing on your lawn, it’s a sign of heavy grub feeding. If you cut out a square in the affected area and lift the turf, you’re likely to find plenty of grubs feeding in that area.
Feeding grubs left unmanaged eventually cause bare spots in your lawn. If you find mounds of dirt around the yard, it means that voles are hunting the grubs. Grubs are the favorite food of voles, and they’ll tunnel through your lawn, destroying the grass in its wake.
Grubs cause damage, and so do voles. Therefore, keeping them out of your lawn is a top priority. Grubs become active after the ground thaws in the early spring. By the mid-summer, you’ll start seeing the effects of grub infestations on your lawn.
The damage starts as discoloration and thinning in the affected area. If you fail to act to resolve the problem, the grass will eventually die off, leaving bare spots on your lawn.
How Do I Know if My Lawn Has Grubs?
As mentioned, the effects of grubs on your lawn become apparent in the mid-summertime. Discoloration and thinning patches of grass are signs of severe grub infestation—however, the only way to be sure of the problem is to check it for yourself.
You’ll need to lift a few square feet of turf around your lawn and look for grubs. If your grass is healthy, there’s no need to do this exercise. However, if you have signs of grub infestation, start with the affected areas first.
If you find grub infestations, it’s best to buy some grub killer for your lawn maintenance this season. Even if your lawn shows no visible signs of grub infestations, preventative care is a good idea.
Purchase the best grub killer, and treat your lawn –Rather take the necessary precautions to prevent grub infestations, rather than wait for them to occur.
Bare patches on your lawn can take the entire summer season to recover, and some might not recover at all. By being prudent with your lawn maintenance and spreading rub killer around the lawn, you ensure you have great looking grass for the entire summer.
Why Is It Necessary to Treat My Lawn for Grubs?
During your grub-checking activities, you need to know what constitutes a grub infestation. Find one or two grubs here, and there are a common occurrence and nothing to concern yourself with during the summer season.
However, if you’re finding more than ten grubs per square foot of grass, you have a problem. You’ll need to purchase the best grub killer to help you kill the grubs and keep your grass healthy.
What are the Best Practices for Controlling Grubs?
If you want to keep your lawn in tip-top condition, year-after-year, make sure you follow these top tips when scouting for grubs.
- Test the soil every other year for nutrient levels.
- Take the soil sample to your local nursery for analysis
- Add fertilizer to give your grass the nutrition it needs during the growing season
- Remember to lay your lawn dressing before the first rains of the season.
- Use your grub killer formula in the second week of summer to stop juvenile grubs from feeding on your grass.
- When mowing your lawn, keep the grass as high as possible to encourage a strong root system.
- If you notice signs of grub infestations, cut up the turf in the affected area and look for grubs.
Do You Get Natural Grub-Killer Products?
Yes, you get all-natural grub killer formulations for your grass. Some homeowners might have an issue with using chemicals on their lawn, and that’s okay. While most insecticide grub killers are safe for use around the yard, they still feature chemical formulations.
There are a few natural grub killer compounds that are suitable for use in your yard. Milky spore is one of the most popular organic treatments, and it’s ideal for use in vegetable gardens as well as lawns.
If you live in a warmer area of the United States, Milky spore offers you an attractive natural grub killer. This product contains agents effective for controlling grubs, Japanese beetle larvae, and a host of other grubs and insects.
However, the milky spore isn’t as effective in colder climates, but it’s worth a try if you live in a warm region. Milky spore takes longer to prevent grubs from feeding on your grass. Therefore, it’s not the best choice for an emergency.
Milky spore is a great lawn dressing to add to your grass at the beginning and midway through the summer season. However, you’ll need to keep using it for it to remain effective. Milky spore is also suitable for use in vegetable gardens, and it’s entirely non-toxic for humans.
The big issue with milky spore is its efficacy and the price tag. Milky spore tends to be one of the more expensive options for grub control.
What are Safe Chemical Products to Use on My Lawn to Kill Grubs?
When using chemical grub killers, make sure you follow the manufacturer’s guidelines for using the product. Granular grub killers are easy to work with and require hand or machine spreading. Remember to wear gloves and wash your hands after applying the pesticide.
Liquid grub killers are harder to manage and mix, but they provide pleasing results, and it’s easy to use a spray bottle to cover your lawn in half the time of hand sowing granular insecticides. All the products in this review are safe for use around the yard.
None of the chemicals in the products listed above are toxic to local wildlife. Therefore, deer and rabbits won’t die if they start feeding on your grass or plants.
Will My Grub Killer Affect Bees and other Pollinators?
All the grub killer products in this review are safe for use in your yard. Some insecticides like “Roundup” contain dangerous chemicals that cause bees to die off if they ingest pollen coated with the product.
However, all the grub killers in this review feature design and formulation with non-toxic ingredients. Therefore, your lawn maintenance kills the grubs but leaves the birds and bees alone.
Whenever you buy a gardening product you are unsure of, ask for advice. You can get great gardening advice and information on insecticide products on online forums or gardening centers.
Can I Use Grub Killer in Flowerbeds?
Yes, some grubs get under your plants, feeding on the roots. This feeding causes slower development of the plants, stunting growth, and reducing yield. If you have a vegetable garden with a grub infestation, it can ruin your crop.
When using grub killers on vegetable gardens, makes sure you go with an organic product containing no chemicals. Look for products approved by the Natural Organic Program (NOP). These grub killers have formulations with no toxic ingredients, making them suitable for use around your vegetables and fruits.
Granular vs Liquid Grub Killer – Which Is Better?
A granular grub killer is a great choice for your lawn, but it’s more hassle to apply. You have the option of spreading it by hand or using a dispenser device. After spreading the grub killer, you’ll need to water lightly to activate the compound.
With a liquid formula, you get a concentrate, taking up less space in your garden shed. Liquid formulas require mixing to the right levels, or you risk burning the lawn. You’ll also need to apply them using a sprayer, but it’s more convenient than hand spreading.
Both options offer viable grub control or your lawn; choose the product that meets your preference.
Grub Killer FAQs
How long does it take the formula the kill grubs?
Most formulas kill grubs on contact, preventing them from feeding. Formulations can act in less than 24-hours, and by the end of the week, your lawn should be grub free. It can take affected parts of your yard up to two months to recover from the effects of grubs. The recovery time depends on the extent of the infestation and the damage.
Can I seed grass after applying my grub killer?
Yes, give you lawn 24-hours to rest after applying your grub killer, and then start sowing. There are no chemicals present in grub killers that damage grass. You can do both simultaneously if you want to save on time, but we recommend spacing them a day apart if possible.
Is there a home-made solution for killing grubs?
Some blogs suggest using laundry detergent as a home remedy for killing grubs. The reality is that this method works, but it’s not the best choice for your lawn. The active ingredients in laundry detergent might damage the roots of your grass, slowing growth.
Where can I purchase the best grub killer?
Pick up your grub killer products from Amazon, the world’s largest eCommerce store. Amazon offers you buyer protection on your order and hassle-free returns. You get the best range at the best prices and free shipping for Prime members.
