But When Is It Too Early To Apply Grub Control

Applying Insecticide to my Lawn Using Scotts Wizz Hand-Held Spreader

When treating your lawn to prevent grub damage for the next season, it would be too early to apply grub preventer on your turf in early spring.

The pesticide will easily disintegrate into the soil and lose its potency by the time the grubs hatch in July through August.

According to the Colorado State University Extension, insecticides are best used in ways that allow them to be in high concentration in the root zone at the same time eggs are hatching and young white grubs are present.

When timing is done right, youll be able to control about 80 percent of the grubworm infestation in the next season.

For the grub killers, you can stop lawn damage almost immediately especially if you follow the right application guidelines on the label of the pesticide.

Not necessarily, because the adult stage of grubs are flying beetles that can travel to your garden from outside your property. Learn more about these beetles.

Preventive Insecticides That Will Prevent Grub Damage Next Fall And Following Spring

These products are used to prevent future grub problems, not to control the grubs present in the lawn in the spring. They will not work on grubs found in the lawn from the middle of October through the middle of May. However, when applied in June or July they provide excellent protection against the next generation of grubs. So, if you need to apply the preventive insecticide BEFORE the grubs are there, how do you know if you need to use an insecticide or not? If you confirmed grub damage the previous fall or spring, meaning you found lots of grubs, then you may want to use a preventive insecticide for one or two years to build a more dense turf that will be tolerant of grubs. If you have treated for several years and you do not see evidence of grubs in your lawn or in the neighbors lawn, it may be time to stop treating. There is an erroneous philosophy being perpetuated that because we have European chafers and Japanese beetles in the area, it is necessary to treat every year or your lawn will be damaged by grubs. This is not true.

In addition, grub control products that contain the active ingredient chlorantraniliprole are safe for bees, even when weed flowers are sprayed. Finally, avoid spray drift or granular spreader drift to flower beds when applying thiamethoxam, imidacloprid, clothianidin or any insecticide for grubs other than chlorantraniliprole

How Do I Know If I Need Insecticide For Lawns

If you have a chafer grub infestation in your lawn, youll be able to see the grubs just below the surface after a quick visual check. Leatherjackets are a little trickier to spot than chafer grubs, as when the grubs are evident in your lawn, it may be too late to treat, as they need catching in the very early stages of maturity. Look out for crane flies, as they will indicate the laying of their eggs which will eventually become leatherjackets.

When To Apply Pesticides

Insect Spray in 2020

Responsible pesticide use in gardens is important, regardless of whether you use a chemical form or a natural homemade combatant. The very fact that it is used to kill something means it requires respectful and smart handling. You should always dress protectively and follow the manufacturers instruction regarding mixing, application rates, and timing.

Pesticide application timing for a direct strike relies upon the product catching the insect at the correct stage. Many insects have several instars and go through metamorphosis. They may be more susceptible to the pesticide as nymphs or as larvae. The literature on the product can help you decide at what point of the insects development it is most effective so you can decide when will be the best time to use a pesticide.

Other factors in application would be wind, rain, and proximity to wildlife.

What Chemical Products Can I Use To Control Grubs In My Lawn

If you have a severe grub infestation and want to use a chemical product to control grubs, you have a number of widely available options.

From about late April into early June, you can effectively use a product with the active ingredient chlorantraniliprole to control all species of white grubs we have in New Hampshire. This chemical also controls caterpillars such as webworms and armyworms. This product is most effective when the grub is actively feeding so applying it 2 to 3 months in advance of severe grub feeding from June to August is recommended. This ingredient is in two widely available products: GrubEx® and Roundup® For Lawns Bug Destroyer. The U.S. EPA designates this chemical as a low risk pesticide due to its low toxicity to bees and other beneficial insects.

Some products registered for controlling grubs just have a pyrethroid, such as products with the active ingredient Gamma-Cyhalothrin, commonly found in the Spectracide® Triazicide® Insect Killer For Lawns. According to research from Michigan State University, products that only contain lambda-cyhalothrin, gamma-cyhalothrin, bifenthrin, deltamethrin, cyfluthrin or permethrin do not work for grub control.

In most cases, whether its early spring or fall, its preferable to simply wait until the next appropriate window for using a preventative product that gets better results and is more targeted. Learn more about current insecticide approaches for white grubs from UMass Extension.

What To Know Before You Spray Your Lawn With Pesticides

This is the time of year when pesticides get sprayed on lawns, parks and golf courses. Though the goal may be to make these green spaces more pleasant places to play fewer bugs, fewer weeds these treatments may not be as safe as you assume.

Most people are not aware of the hazards that the unthinking use of pesticides poses to their children, says Philip Landrigan, dean for global health and a professor of pediatrics at the Mount Sinai School of Medicine in New York. Pesticides include herbicides to kill weeds and insecticides such as those sprayed to manage cockroaches and other pests.

Pound for pound, children receive much higher exposures to these chemicals than adults do, just through normal daily activity, Landrigan says. Because children are growing quickly, they take into their bodies more of the pesticides that are in the food, water and air, he says. They also roll around in the grass and put their fingers in their mouths, which greatly increases exposure.

Researchers are learning a great deal about how vulnerable childrens brains are to pesticides during fetal and early childhood development. These delicate developmental processes are easily disrupted by very small doses of toxic chemicals that would be virtually harmless for an adult, Landrigan says.

Unfortunately, flags generally do not give people adequate warning, says Ginsberg, author of Whats Toxic, Whats Not. And many people ignore them, he says.

As a result, leaf-eating bugs may wreak havoc along the way.

A trained technician can quickly apply a broad-spectrum product to the perimeter. He can also add mulch, ground cover, and shrubs to thoroughly protect your property from invaders.

    How Bad Are Grubs For The Lawn

    Grubs, which are the larval, or immature, stage of several species of beetles and chafers, can damage a lawn by feeding on the roots of your grass. Healthier grass can tolerate more grub feeding, and all grass can tolerate some grub feeding.

    A grub infestation will cause patches of thinning turf, and these patches will gradually increase in size. Often times grub damaged grass will pull out very easily at the roots.

    What we often hear from homeowners is that they believe they have grubs because animals like moles, skunks, crows and racoons are digging in the lawn. This isnt a reliable clue, however, because grub infestations arent always accompanied by animal damage and animal damage doesnt always result from a grub infestation. These animals feed on other insects in the lawn, like earthworms, which are beneficial to the health of the lawn. That all said, if you do have grubs and animals are digging for them in the lawn, that can be detrimental to the health of your turf and to the appearance of your yard.

    If you have a very high concentration of grubs 10 or more grubs per square foot treatment may be necessary to maintain healthy grass. However, if you have a lower count of grubs, yet arent seeing good results in your lawn, thats a clue that you should revisit your lawn care practices more broadly.

    Some of the best practices we recommend are:

    • Testing your soil every 2-3 years, and following the fertilizer and amendment recommendations.
    • Keeping grass mowed high at least 2, and ideally 3 or more which means that your grass will have a deeper, healthier root system that can tolerate more sub-surface insect feeding.
