For an organic grub control we chose Milky Spore Powder.  The following are some top questions and the answers, that come with this product.  

Q: How fast does the spore work and how long does it last?

A: Milky Spore begins working as soon as it is applied as long as grubs are feeding.  Once grubs are infected they will multiply the spore by several billion times and spread it further.  In warm climates, good control can occur for two to three years.  In colder areas, such as New England, it will last for four to five years.  Once established in a lawn, however, Milky Spore has been known to last 15-20 years.  

Q: Can I use it in the vegetable garden?

A: Absolutely!  Milky Spore is harmless to food crops.  It is not a harmful chemical pesticide.  It may be used in gardens, lawns, flowerbeds, and around ponds and wells. 

Q: What about Moles and Gophers?

A: Eliminating grubs with Milky Spore often cause moles, gophers and skunks to feed elsewhere.  Milky Spore does not affect moles and gophers, it only eliminates their food source.

Q: Can I wait to water in the Spore?

A: It's best to water in the spore as soon as it is finished being applied.  Direct UV rays can damage the spore and be a cause for re-treatment.

Q: Should I keep my pets off the lawn?

A: Milky Spore does not affect pets, beneficial insects, fish, bees, birds, plants or humans.  It is non-toxic.
