Is grubGONE! Safe for Beneficial Insects and Pollinators?

Is grubGONE! Better than 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 many borers:

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

grubGONE! is composed of the natural soil bacterium Bacillus thuringiensis galleriae (Btg), but most of the activity in the soil comes from the ingestion of the stable protein derived from the Btg; it is therefore not dependent on the the finicky conditions required for the bacterium to reproduce.  grubGONE! is stable for years and is effective at any temperature range in which grubs are feeding. Milky Spore must grow and reproduce in order to be effective, and therefore has a limited temperature range in which it will possibly work. In soils in the northeastern United States and some other parts of the country, the Milky Spore bacteria do no survive in the soil for extended periods, contrary to claims otherwise (see references below). 

• University of New Hampshire: " The milky spore bacterium is not effective in northern New England because spring soils are too cold. “
• University of Connecticut: "Milky Spore has not been very successful in controlling white grubs."
• University of Vermont: "Milky Spore...(has had) relatively poor or inconsishttps://homegarden.cahnr.uconn.edu/factsheets/grub-problems-in-turf/tent results in the field."
• Cornell University: Does Milky Spore Work? "The overall effect of Milky Disease is as a population suppressant, not as a direct control."
• Reasons You Should Not Be Using Milky Spore.

When are grubGONE! and beetleGONE! Applied?

Exact application timing will depend on your location and climate, but in general:
• Optimal timing is late July or early August when beetle eggs are hatching and grubs start feeding (preventative treatment).  However, grubGONE! can also be applied through the fall as a curative treatment as well, a major advantage over even synthetic grub products as grubGONE! has both curative and preventative properties.
• 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.
The chart below provides general guidelines for when to apply grubGONE! and beetleGONE! in most milder climates of the United States:

Application Instructions for grubGONE!

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).
*As an alternative when a wettable powder is needed, beetleGONE! (which contains the exact same Btg active ingredient) at a rate of 0.25 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).

Application Notes for grubGONE!

• grubGONE! should be watered in (1/4 inch 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.
