grubGONE! Description

For Organic Lawn Care, this easy to apply granule is effective at controlling various types of evasive grubs. grubGone! is the first Bacillus thuringiensis galleriae (Btg) bio-insecticide to control turf grubs at a level of efficacy equivalent to chemical standards, but without the harmful side effects or off-target damage to beneficial insects or pollinators, such as honeybees, ladybugs, fish or birds. With grubGONE!, entire landscapes can be economically, effectively and safely protected from destructive beetle grubs, such as Japanese, Asiatic, June and Oriental Beetles, European Chafers and many more. Unlike other biological or chemical grub-control products, grubGONE! is an effective control of all life stages of grubs including the later 2nd and 3rd-instar forms, and can therefore be used as either a curative early season remedy or preventative treatment in September - October for grub control all season. Furthermore, since the active ingredient Btg is derived from a naturally occurring soil bacterium, grubGONE! is safe for the environment and can be applied in areas that are frequented by kids and pets.

grubGONE! Benefits

• Novel & natural Bacillus thuringiensis galleriae (Btg) strain.
• Broader range of control: Can be used as a curative and preventative treatment for grubs!
• Works on all scarab grubs including Japanese Beetles, Masked Chafers, Asiatic Garden Beetles, Oriental Beetles, European Chafers, some Weevils and more.
• Proven to not harm bees, pollinators, or other beneficial insects (i.e. parasitic wasps and beneficial nematodes that also kill grubs).
• Protects the value of turf landscapes and ornamental plants by effectively controlling susceptible white grubs in the season of application
• Works on all stages of the adult beetle and larval (grub) stages; including the 1st through 3rd instar grub stages.
• Can be applied with other insect controls
• A non-chemical choice for areas that kids and pets frequent
• Is effective in cooler temperatures than other biologicals.
• Shelf life is greater than 2 years when stored as directed

grubGONE! Application Directions

Apply 2 lbs. (32 oz.) of grubGONE! per 1,000 sq. ft. of turf grass or ornamental plants (equivalent to 87 lbs. of grubGONE!, or about 2x of 40 lbs. bags  per acre).

• grubGONE! should be watered in (1/4 in. of water) within a few days of application or UV degradation can lead to lower product performance over time.
• grubGONE! can be applied and is effective any time grubs are feeding, including spring.  grubGONE! can kill grubs in all 3 instar stages, as long as they ingest the product.
• We do not suggest applying grubGONE! below 50°F, or any time grubs may not be feeding. Check with your local experts to determine optimal temperatures. You can check your soil temperatures accurately and for free by following the link here and simply entering your zip code.
• As an alternative when a liquid application is desired instead of a granular, beetleGONE! (which contains the exact same active ingredient) at a rate of 0.35 lbs. per 1,000 square feet (in 1 to 2 ounces or 1/2 a cup per gallon of water). Efficacy and price are almost identical between grubGONE! (granular) and beetleGONE! (wettable powder or liquid application).

When is grubGONE! Applied?

Exact application timing will depend on your location and climate, but in general:

• Optimal timing for preventative treatment is late July or early August when beetle eggs are hatching and grubs start feeding. However, grubGONE! can also be applied through the Fall as a curative treatment. The dual quality of having both curative and preventative properties, serves as a major advantage for grubGONE! over other grub products, even synthetic.
• grubGONE! can be effectively applied in the Spring, as well as in the Fall. This is especially helpful if animals (moles, skunks, raccoons, birds etc...) are causing turf damage as they feed on the grubs. A Spring grub treatment will not necessarily preclude a second Summer/Fall treatment, however, as the adult beetles will lay eggs beginning in July and the cycle may begin again.

grubGONE! vs. Milky Spore

grubGONE! has the broadest range of effectiveness against grubs in the non-synthetic market, and does it without harming beneficial insects!  Milky Spore is only effective against Japanese Beetle grubs; grubGONE! has a much broader spectrum of control against white grubs including not only Japanese Beetle grubs but also Asian and Oriental Beetle grubs as well as many chafers (such as the European) and borers:

Even more, grubGONE! is also effective against adult beetles as well as all stages of grubs (1st through 3rd instar stages) - Milky Spore is not. You get a more complete protection with grubGONE!

grubGONE! is composed of the natural soil bacterium Bacillus thuringiensis galleriae (Btg) but more the stable protein the microbe makes that is toxic to only grubs.  It is therefore not dependent on the finicky conditions required for the bacterium to live like Milky Spore.  grubGONE! is stable for years and is effective at any temperature range grubs are feeding. Milky Spore has a limited temperature range to work. In soils in the northeastern United States and some other parts of the country, the Milky Spore bacteria do not survive in the soil for extended periods, contrary to claims otherwise (see references below).

grubGONE! Shelf Life

The shelf life for grubGONE! is greater than 2 years with no special storage requirements or refrigeration needed.
