To kill grubs in the spring or fall, use carbaryl or trichlorfon.
There are only 2 chemicals labeled for curative control of all species of white grubs: carbaryl and trichlorfon. These are ``24 hour grub killer'' type products. They can be applied whenever grubs are actively feeding.
However, since Chlorantraniliprole also kills active grubs, you get a little extra piece of mind with it. Now, if you are reading this article and it's the fall time and you have found actively feeding grubs, DO NOT use Scotts GrubEx.
This is why we recommend Grub Guard Ultimate, Acelepryn GR and Acelepryn Liquid. Acelepryn provides safe and effective control of black beetle while minimising the impact on the environment and non-target organisms, such as bees and earthworms.
You can get rid of grubs naturally by introducing natural predators, limiting the moisture your lawn receives, deploying milky spore or beneficial nematodes, using neem oil, creating a grub killer with borax, and dethatching and aerating your lawn. Conventional grub control methods include carbaryl and trichlorfon.
The adult stages of white grubs are scarab beetles. Common names for some of the species include June beetles, chafers, and dung beetles. Only a few species of white grubs' damage turfgrass, and most feed on decaying plant material and animal manure, proving a necessary role in recycling nutrients of these materials.
The maximum number of Grubex applications is one per year. Jonathan Green Grub & Insect Control can be applied up to 3 times per year. Apply your grub control to a dry lawn with a rotary spreader. Make sure to follow the spreader settings provided on the product's packaging.
So when exactly is the right time? Typically, late May through July is the prime period to apply grub control treatments for southeastern lawns. Monitor for the first signs of grub activity like irregular brown patches, spongy turf, or an uptick in moles/raccoons digging in search of a grub buffet.
Customers say that Sevin Insect Killer Lawn Granules are effective in controlling a wide range of pests, including ants, fleas, and grubs, with many noting quick results after application. Users appreciate the ease of application and the product's safety for pets and gardens.
Apply Scotts® GrubEx®1 Season Long Grub Killer to a dry lawn in the spring or early summer to kill grubs as they develop. We recommend using a Scotts® spreader to apply this product.
Luckily, your lawn can recover! Schedule an overseeding service to help thicken your turf after a grub infestation. By spreading grass seeds across your lawn, your lawn will be filled with new, green grass that will fill in any bare or patchy areas that were caused by grub damage.
It will take 10-14 days for the grubs to begin dying after the insecticide is applied.
Dish detergents disrupt the cell membrane of these soft, small insects and smother them to death. Grubs drown in dish soap and are suffocated by the fluid coating them. Dish soap has been shown to kill other lawn insects as well, and even dries out and kills fungus in lawns.
Skunks and raccoons are not the only creatures that will feed on grubs. Crows will search for them as well.
Both are excellent products and very effective at killing a wide range of common grubs that may be living on your soil. Scotts GrubEx is a contact and prevention insecticide, while the Bayer Grub Killer Plus eliminates Grubs on contact within 24 hours. And they are sold in ready-to-use granular bags.
Imidacloprid is highly effective and long-lasting, providing up to 4 months of control. One of the benefits of imidacloprid is that it is safe for use around pets and wildlife, and is not harmful to beneficial insects. We consider imidacloprid to be the overall best grub killer.
Although the grubs do not feed on turfgrass, their tunneling can cause problems if there are more than five to seven grubs per square foot. After treatment, the grubs will come to the surface within 12 hours. As they decay, the odor can be very strong.
If a neighbor has a lawn Grub problem, emerging Beetles will likely migrate toward your grass. They love moisture; populations peak in soil that's consistently moist. (More female beetles lay eggs in well-maintained turf, and the eggs that hatch develop better in such turf than they do in dry, stressed turf.)
Use a spreader to apply Scotts® GrubEx®1. Be sure to follow application directions. To activate the product, water immediately after applying. A drought-stressed, underfed lawn will show grub damage faster, and with fewer grubs per square foot, than a properly-fed, well-maintained lawn.
However, some customers have experienced inconsistent results, particularly with existing grub infestations, and noted that multiple applications may be necessary for optimal effectiveness. Overall, GrubEx is viewed as a reliable product, though some find it to be on the pricier side.
Once grubs discover your lawn, they won't let go unless you make them. They'll come back every spring, destroying your lawn's roots all over again.
Simple steps to try to control grubs include applying beneficial nematodes. Nematodes are microscopic worms. As larvae, nematodes will eat grubs. Castor oil granules can be spread over your lawn to control pests like moles, voles and raccoons that are seeking grubs.
