Grub Control

It is not necessary for the anyone to spread potentially hazardous toxic chemicals on their lawn to try to stop the spread of grubs in the turf. Milky Spore (Bacillus popilliae) is an environmentally friendly alternative that is easy to apply and does not pose any harmful threat to children or pets. According to Cornell University, between 1939 and 1953, over 100 tons of spore powder was applied to turf in over 160,000 sites in the U.S. as part of a government program. Larval numbers in the turf decreased 10- to 20-fold and the population stabilized at this new low level with corresponding reductions in the levels of adult beetle damage.

According to the U.S EPA, spores of Bacillus popilliae infect larvae (grubs) of Japanese beetles, eventually killing the larvae and preventing their development into adult beetles. As a pesticide active ingredient, the spores of this bacterium are approved for use on lawns and ornamental plants around residential areas. The spores also infect larvae of some closely related beetles, but do not infect other non-target organisms, such as other insects, birds, mammals, earthworms, and plants. No harm is expected to humans or the environment from use of pesticide products containing spores of B. popilliae.

Before you jump to a potentially hazardous conclusion, I urge you to take a look at the Web site of the maker of Milky Spore, St. Gabriel Laboratories at http://www.milkyspore.com/milkyspore.htm and consider using this product.
Milky spore is widely available on the Internet and in many better-quality lawn and garden centers.
