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.
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.
The standard, and highly effective, grub control insecticides are products that contain imidacloprid, clothianidin or thiomethoxam. There is one insecticide product in a different chemical class that will give a similar level of grub control: chlorantraniliprole (Acelepryn).
GrubEx prevents Grub larvae from growing in the summer. It would be best if you used GrubEx in May. The active ingredient takes time to reach the root zone, so grubs will be controlled in June and beyond.
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.
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.
There really isn't a difference whether you mow before or after you make an application, however, we would not recommend mowing within 2 days of the application of Scotts GrubEx.
Grubex is not effective on mature grubs. Larger (mature) grubs are harder to control and resistant to most controls on the market. This product needs to be applied as a preventative in spring or early summer (prior to 4th of July) before damage is present, once damage is noticed it is too late.
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.
GrubEx is a well-known brand that contains chlorantraniliprole, the primary ingredient in grub killers. It is commonly used to manage grub infestations in mature lawns and can also be used while planting new grass.
Applying grub control in late spring or early summer, typically between April and June, will help to disrupt the lifecycle. This is when grubs are in their earliest developmental stages, and the treatment will be most effective.
Moist soil. Whether you over-water your lawn or have poor drainage, excess moisture creates an ideal habitat for grubs. Thatch. Beetles like to hide and lay their eggs in thick layers of grass rich in organic material so there's plenty of food for the larvae once they hatch.
Failure to water-in insecticides after application may result in poor grub control - Turf.
It is often best to put down grub preventers from April through mid-July when grubs are ready to hatch. If you want to stop grub damage right away, the best time to apply a grub killer to your lawn is when you first see signs of damage.
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.
The active ingredient needs watered into the soil before it is affective. Entire lawn must be treated for complete control. Application to water-logged lawn prevents product from getting into root zone.
As fall begins to approach, the cooler weather may provide your lawn relief from the stress of the summer heat and humidity, but it also brings another threat to your lawn's health. The month of September and into early October can bring grubs to your yard.
No, GrubEx is not safe for pets right after you applied it.
Grub damage takes the form of irregularly shaped brown patches on a lawn. It usually makes its first appearance in August is sometimes mistaken for drought harm. Unlike a drought-damaged lawn, grub-infested turf peels up easily from the soil because its roots have been depleted.
