10 best grub control

Grub control is a term related to pest control in the context of lawn and garden maintenance. It specifically pertains to the management and prevention of grubs, which are the larvae of certain types of beetles, most commonly white grubs.Grubs can be destructive to lawns, as they feed on the roots of grass and other plants, causing damage to the turf. Here are some key points related to grub control:

  1. Identification: Grubs are creamy white, C-shaped larvae that can vary in size depending on their stage of development. They are typically found just below the soil surface, where they feed on plant roots.

  2. Damage: Grubs can cause significant damage to lawns and gardens. Signs of grub infestation include brown patches of grass that can be easily pulled up due to root damage. Additionally, increased activity from birds and other wildlife digging in the lawn to feed on grubs may be a noticeable sign.

  3. Lifecycle: Understanding the lifecycle of grubs is crucial for effective control. Grubs typically hatch from eggs in the soil, feed on plant roots during the summer and fall, and then overwinter deeper in the soil before pupating and emerging as adult beetles in the spring or early summer.

  4. Prevention: There are several preventive measures to control grubs. One common approach is to apply grub control products or insecticides to the lawn in the late spring or early summer when the grubs are still close to the surface and actively feeding. These products work by targeting the grubs before they can cause extensive damage.

  5. Cultural Practices: Maintaining a healthy lawn through proper watering, mowing, and fertilization can help reduce the attractiveness of your lawn to egg-laying adult beetles. A healthy lawn with strong grass roots is less susceptible to grub damage.

  6. Biological Control: Some beneficial nematodes and microbial insecticides can be used as biological controls to target grubs. These natural predators can help reduce grub populations.

  7. Chemical Control: Chemical pesticides are available for grub control, but they should be used with caution. It's essential to follow the manufacturer's instructions and consider the potential environmental impact.

  8. Timing: Timing is critical when applying grub control products. Applying them too early or too late in the season may not be as effective.

  9. Monitoring: Regularly inspecting your lawn for signs of grub damage and monitoring grub populations can help you decide when and if treatment is necessary.

In conclusion, grub control is a vital aspect of lawn and garden care, particularly for those dealing with white grubs and related beetle larvae. Proper identification, preventive measures, and choosing the right control methods are key to maintaining a healthy and vibrant lawn while minimizing grub damage.

User questions & answers

Question: Can this be used under fruit trees ie. Apple, pears, blueberries etc?? I need to be 100% sure and would like responses fro those whom are certain
Answer: I always want to give good information on this poisen. I can not answer your question. I use Bayer poisen for the yard and around the headges and for flea controll. I contacted Bayer about useing it during the hot summer months in Fl when the tempature reaches above 90*; Bayer informed me that it stops killing insects above 90*. For fruit trees you need to call their 800 # and ask them or your county Agracultrial Agent. Have a safe growing season. Dallas
Question: Will this work in flower beds with weed fabric and ceder mulch on top? Worried it won't get down to the grubs
Answer: This substance is a solvent. it will eventually dissolve and absolve in ground, so it would work when spread over mulch.
Question: does this kill chiggers? the normal insect killers won't work because they're arachnids, but noticed it does kill spiders and ticks
Answer: Yes it specifically lists chiggers as a pest it will control. Thanks for considering your purchase from Amazon through AgCareDirect.
Question: will this kill honeybees
Answer: Thats a good QUESTION. I dont know I would call Bayer and talk to them. Also make sure you read the MSDS INFORMATION and the instructions on how to speead it. Bayer is good for killing fleas and ticks. It lasts three months and use it untill the out door temps hit 90* or above. I live in Jax Fl. I use a comertial pest controll service year round and I have them spray for fleas during the 90* hot summer months. Comertial liquid poisen kills the fleas and ticks above 90*. I either just dump the bag in my spreader or sometimes use rubber gloves and speead it around the foundation of my house to kill roaches before they have a chance to get in. Also, BAYER does not kill anything if you use it during the hot days of summer when the tempature is above 90*. I called Bayer and read it on the MSDS sheet. Hope I helped you out. I was a Hamat Tech when I was a Firefighter now I am retired. Have a good spring.

User questions & answers

Question: How long do have to wait to mow again after applying duocide
Answer: Most granular products fall into the thatch layer so if it hasn’t been watered in you likely won’t suck up many of the granular. I would recommend lightly watering in after you apply which allows the granuals to disperse.
Question: Why can't this Product be shipped to California
Answer: Ask your state and local government. It probably has to do with their restrictions.
Question: They are destroying my tangerine plants. Applying it 2 ft away won't help. If there are no fruits, can it be applied closer to the root
Answer: Ues
Question: Is it safe to use at the same time I put down pre-emergent
Answer: I can’t answer that; I sprayed my pre-emergent back in February and I didn’t didnt put the Andersons Duocide Lawn Insecticide until April. I do suggest watching the short video on lightly watering and then 30 minutes later repeat to expedite its absorbing into the ground. I did apply other fertilizers etc. prior to the insecticide though. It does break down very easily, so I would say if the insecticide was put down and watered into the ground as recommended then I wouldn’t think that there would be a problem

The Andersons DuoCide is a professional-grade, curative lawn insect control. Fast acting DuoCide eliminates more than 50 common lawn pests, including grubs, ticks, fire ants and fleas. With a unique formula containing both bifenthrin and carbaryl, DuoCide eliminates lawn pests above and below the soil surface with a single application.

Applying DuoCide

Application rates range from 2-8 lbs/1000 sq ft and vary based on pest(s) to be controlled. See the chart below for more detail.

Proper application timing depends on pest(s) to be controlled. For surface pests (ants, spiders, billbugs, chinch bugs, etc.), treat when pests or turf damage symptoms first appear. For subsurface pests (white grubs, june beetles, etc.), apply 10-14 days after egg-laying activity and/or when turf damage is first noticed. See DuoCide label for complete detail.

Irrigation Required

DuoCide must be watered in immediately after application. Upon contact with water, DuoCide granules will disperse into thousands of microparticles, moving the active ingredients through the turf canopy and into the soil.

User questions & answers

Question: Does this also kill earthworms
Answer: While I don’t know for absolute sure, I don’t think so. I learned about this product from a YouTube video from Silver Cymbal, and he said it was pretty specific to grubs, and NOT other insects, but a much wider variety of grubs than milky spore. But I realize earthworms are not technically insects. That video is titled “How to get rid of grubs ORGANICALLY in the LAWN”. Reading the bag, it lists a lot of beetle type bugs that it controls but not other insects or worms. Risk to earthworms are not mentioned anywhere on the bag or in the YouTube video. But he does say it is safe for bees. Hope that helps. I’ll be very upset myself, if this kills earthworms. It is recommended for lawns and garden beds so I really don’t think it will hurt worms.
Question: When and how often do i apply
Answer: If you live in Northeast USA it’s to late. Application should have been applied. Google your zip code to determine when the optimum time to apply the 1st application. Then I’d apply again in 30 days. You can also contact your local Cooperative Extension for their recommendation. Last recommendation Is ask one of the neighborhood lawn service workers. Good luck
Question: Does it kill Japanese beetle grubs
Answer: Yes
Question: Does this kill beneficial earthworms
Answer: No. The product is non-toxic and unharmful to wildlife including earthworms, pollinators, insects, birds, and fish.

Stop the Damage Before it Starts!

Grubs and other insects can cause serious damage to lawns if not kept under control. After feeding on the roots, grubs leave grass looking brown and wilted, sometimes beyond repair.

The Andersons Organic Grub Control prevents grub damage and the destruction caused by foragers like moles and raccoons, who are known for rummaging through yards looking for grubs. Controlling grubs also helps to control the population of other pests like beetles, chafers, weevils, and emerald ash borers in your yard.

100% Organic and OMRI-Listed

Organic Grub Control is made of 100% organic ingredients and carries an OMRI Listing, certifying its ingredients for organic use. Containing the natural soil bacterium bacillus thuringiensis (Bt) galleriae, Organic Grub Control is as effective as chemical treatments without any of the dangers.

Won't Harm Beneficial Insects or Pollinators

While ridding your yard of grubs, beetles, and foragers like moles, skunks, and raccoons looking to feed on grubs, Organic Grub Control won't cause damage to earthworms, beneficial insects, or pollinators like bees, butterflies and ladybugs.

Safe for the Whole Family

Organic Grub Control helps create a beautiful yard the whole family will be able to enjoy, without restrictions. Because the product is 100% organic and toxin-free, children and pets can return to the treated area immediately following application!

Eliminate Grubs and Other Turf Damaging Pests

The Andersons Organic Grub Control is effective against annual white grubs of the annual bluegrass weevil, Asiatic garden beetle, chafer, green June beetle, Japanese beetle, May or June beetle, northern masked chafer, oriental beetle, and the southern masked chafer.

Application Timing

A spring application of Organic Grub Control shortly after the ground has thawed can be used to control grubs coming to the surface of your lawn to feed on roots. In mid-to-late summer, Organic Grub Control can be used to target newly-hatched grubs and prevent damage from foragers like birds, raccoons, moles, and skunks.

For those looking for maximum protection, Organic Grub Control can be applied again in the fall to minimize over-wintering grubs and set your lawn up for spring success.

To ensure best results, Organic Grub Control should be watered in with irrigation or rainfall.
